Description

Technical Field

[0001] This invention relates to the field of magnetic material processing. More specifically, this invention relates to a spiral tile processing apparatus and a processing method thereof. Background Technology

[0002] Neodymium iron boron permanent magnets are widely used in permanent magnetic field devices and equipment such as electroacoustics and telecommunications, motors, instruments, nuclear magnetic resonance, magnetic levitation and magnetic sealing due to their excellent properties of high remanence, high coercivity and high energy product, and easy processing into magnets of various shapes and specifications. They are particularly suitable for manufacturing various high-performance products, such as tile-shaped products of various sizes in permanent magnet motors, VCM sheets in optical drive motors, irregularly shaped magnets in the acoustic field, and helical magnets in oil exploration drilling rigs.

[0003] Due to the excellent conductivity of neodymium iron boron magnets, most irregularly shaped products are processed using wire electrical discharge machining (EDM). The ease of operation of wire EDM with 3B code programming, along with the machine's machining accuracy within 0.005mm, and the fact that neodymium iron boron magnets are brittle and hard, mean that apart from EDM, various machining tools are almost unable to process them; only grinding can achieve various shape requirements.

[0004] Given this situation, how to process spiral roof tiles is a huge challenge facing the NdFeB industry.

[0005] Spiral roof tiles consist of two curved surfaces, two flat surfaces, and two helical surfaces. Wire EDM can only machine the two curved surfaces and two flat surfaces; the two helical surfaces require secondary machining using a five-axis machining center. However, currently, such five-axis machining centers can only produce laboratory samples and cannot achieve mass production. Furthermore, using a five-axis machining center for these helical surfaces is prone to chipping and corner breakage, and the processing cost is very high and inefficient. Therefore, achieving high-efficiency, low-cost mass production of spiral roof tiles is a pressing problem that needs to be solved in this field. Summary of the Invention

[0006] This invention provides a spiral tile processing device and method, which can quickly and efficiently grind the inclined surface of the spiral tile blank into a spiral curved surface. This not only enables low-cost batch processing to increase production capacity, but also improves efficiency and reduces labor intensity.

[0007] To achieve these objectives and other advantages of the present invention, in a first aspect, the present invention provides a spiral tile processing apparatus, comprising:

[0008] A rotating component has a groove with a helical curved surface on one side along the circumferential direction;

[0009] A fixed station is set on the rotating assembly to fix the spiral tile blank to be processed and to position the inclined surface of the spiral tile blank that needs to be ground to produce a spiral surface above the spiral surface of the groove.

[0010] A helical guide assembly includes a first rotating shaft and a moving component that performs linear motion on the first rotating shaft. The axial direction of the first rotating shaft and the axial direction of the rotating component are horizontally arranged, and the first rotating shaft and the rotating component rotate synchronously in the same direction.

[0011] A grinding device is fixed on the moving part of the spiral lead assembly, and the rotating grinding head of the grinding device is positioned next to the spiral curved surface and can contact the inclined surface of the spiral tile blank. When the rotating assembly rotates, the first rotating shaft rotates synchronously, driving the moving part to make linear motion, thereby driving the rotating grinding head of the grinding device to move and grind the inclined surface of the spiral tile blank into a spiral curved surface.

[0012] Preferably, in the spiral tile processing device, the first rotating shaft and the rotating assembly are arranged to rotate synchronously and in the same direction as follows: a driving wheel is provided at one end of the rotating assembly, and a driven wheel is provided at one end of the first rotating shaft, and the driving wheel and the driven wheel are connected by a synchronous belt.

[0013] Preferably, in the spiral tile processing device, the rotating assembly includes a second rotating shaft and an annular column disposed on the second rotating shaft, with the groove disposed on the annular column; the fixed station includes an arc-shaped plate and an arc-shaped cover, the arc-shaped plate is fixed on the annular column, and an arc-shaped groove is disposed on one side of the arc-shaped plate for placing the spiral tile blank to be processed, the arc-shaped cover is fixed on the arc-shaped plate and covers the arc-shaped groove to fix the spiral tile blank to be processed, wherein a through hole is disposed on the other side of the arc-shaped plate, and an adjusting bolt is disposed in the through hole to prevent the spiral tile blank to be processed from moving into the arc-shaped groove during the grinding process.

[0014] Preferably, the spiral tile processing device has a swing arm on the second rotating shaft, through which the reciprocating rotation of the second rotating shaft is realized.

[0015] Preferably, in the spiral tile processing apparatus, the grinding device includes:

[0016] A guide slide is fixed on the moving part of the helical lead assembly, and the movement of the moving part drives the guide slide to move.

[0017] The X-axis dovetail slide is fixed on the guide rail slide, and the sliding cover of the X-axis dovetail slide moves in a direction perpendicular to the moving direction of the moving component.

[0018] The Y-axis dovetail slide is fixed on the slide cover of the X-axis dovetail slide, and the sliding cover of the Y-axis dovetail slide moves in a direction parallel to the moving direction of the moving component.

[0019] A high-speed grinding device is installed on the slide cover of the Y-axis dovetail slide, and a cylindrical rotating grinding head is installed at the end of the high-speed grinding spindle of the high-speed grinding device.

[0020] Preferably, the spiral tile processing device further includes two first support members. The spiral guide assembly and the rotating assembly are rotatably disposed between the two first support members, with the spiral guide assembly located below the rotating assembly. The first shaft end of the driven wheel and the second shaft end of the driving wheel both pass through one of the first support members and are then connected by the timing belt.

[0021] Preferably, the spiral tile processing device further includes a base plate, on which the two first support members are fixed; on the base plate, two cylindrical support rods are also provided, the axial directions of the two cylindrical support rods are parallel to the axial direction of the first rotating shaft, and movable sliders are provided on the two cylindrical support rods, the sliders being fixedly connected to the bottom surface of the guide rail slide table to support the guide rail slide table.

[0022] Preferably, the spiral tile processing device further includes a fixing plate, the bottom surface of which is fixed to one end of the guide rail slide, and the side surface of which is fixed to the moving part.

[0023] Secondly, the present invention provides a method for processing spiral roof tiles, applied to the aforementioned spiral roof tile processing apparatus, comprising:

[0024] Step 1: Obtain the rough blank of the spiral tile to be processed, which has two arc-shaped surfaces, two planes and two inclined surfaces. The two inclined surfaces need to be processed into spiral curved surfaces.

[0025] Step 2: Place the spiral tile blank in the arc-shaped groove, then fix the arc-shaped pressure cap, and rotate the adjusting bolt to expose the spiral curved surface of the groove body on the inclined surface to be processed of the spiral tile blank.

[0026] Step 3: Adjust the X-axis dovetail slide and the Y-axis dovetail slide to adjust the feed of the rotary grinding head, so that the rotary grinding head is located next to the helical surface of the groove and at an appropriate distance from the helical surface, to ensure that the inclined surface to be processed is ground into a helical surface;

[0027] Step 4: Rotate the swing arm, rotate the rotating component, rotate the second rotating shaft, and drive the first rotating shaft to rotate synchronously through the synchronous belt, so that the moving part makes linear motion, drives the guide rail slide to make linear motion, so that the rotary grinding head makes linear motion. The rotary grinding head that makes linear motion, the spiral tile blank that makes circular motion, and the set groove spiral curved surface cooperate with each other to grind the inclined surface of the spiral tile blank into a spiral curved surface.

[0028] Step 5: After one of the inclined surfaces is ground into a spiral surface, rotate the spiral tile blank 180 degrees and reinstall it. Then, following the order of steps 2 to 4, grind the other inclined surface into a spiral surface.

[0029] The present invention has at least the following beneficial effects: First, because the rotating component of the present invention has a groove with a helical curved surface on one side along the circumferential direction, it provides a suitable moving space for the moving trajectory of the rotary grinding head. A fixed station for fixing the spiral tile blank is provided on the rotating component, located above the helical curved surface of the groove, so that the inclined surface to be processed on the spiral tile blank slightly protrudes from the helical curved surface of the groove. This ensures that the rotary grinding head grinds the inclined surface without damaging the helical curved surface of the groove. Second, the first rotating shaft of the helical lead component of the present invention rotates synchronously and in the same direction as the rotating component. That is, the rotating component rotates counterclockwise downwards, and the helical curved surface of the groove and the spiral tile blank also rotate counterclockwise downwards. The first rotating shaft also rotates counterclockwise synchronously, driving the moving component to move forward in a straight line, thereby driving the rotary grinding head to move forward in a straight line. Relative to the rotating component, with the rotating component as a reference, the moving trajectory of the rotary grinding head is spirally upwards. This configuration ensures that the rotary grinding head grinds the inclined surface of the spiral tile blank into a helical curved surface. Therefore, the implementation of this invention requires the coordinated action of a rotary grinding head that moves linearly, a spiral tile blank that moves in a circular motion, and a spiral curved surface of a groove. The technology provided by this invention can improve the processing efficiency of spiral tiles, enable low-cost mass production, and reduce labor intensity.

[0030] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0041] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0042] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are conventional methods, and the reagents and materials mentioned are commercially available.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0043] like Figures 1-4As shown, the spiral tile processing device provided in this embodiment of the invention includes: a rotating assembly 1, which has a groove 130 with a helical curved surface 131 on one side along the circumferential direction; a fixed station 2, which is disposed on the rotating assembly 1 to fix the spiral tile blank 11 to be processed, and to position the inclined surface of the spiral tile blank 11 to be ground to have a helical curved surface above the helical curved surface 131 of the groove 130; and a spiral lead assembly 3, which includes a first rotating shaft 310 and a moving part 320 that moves linearly on the first rotating shaft 310, wherein the axial direction of the first rotating shaft 310 and the rotational direction are respectively connected. The axial direction of component 1 is horizontal, and the first rotating shaft 310 and the rotating component 1 rotate synchronously in the same direction. The grinding device 4 is fixed on the moving part 320 of the spiral lead component 3, and the rotating grinding head 441 of the grinding device 4 is located next to the spiral curved surface 131 and can contact the inclined surface of the spiral tile blank. When the rotating component 1 rotates, the first rotating shaft 310 rotates synchronously, driving the moving part 320 to make linear motion, thereby driving the rotating grinding head 441 of the grinding device 4 to move and grind the inclined surface of the spiral tile blank 11 into a spiral curved surface.

[0044] In the above embodiments, the rotating assembly 1 of the present invention has a groove 130 with a helical curved surface on one side along the circumferential direction, thus providing a suitable moving space for the moving trajectory of the rotating grinding head 441. A fixing station 2 for fixing the spiral tile blank 11 is provided on the rotating assembly 1, located above the helical curved surface of the groove 130, so that the inclined surface to be processed on the spiral tile blank 11 is slightly exposed on the helical curved surface of the groove 130. This ensures that the rotating grinding head 441 grinds the inclined surface without damaging the helical curved surface of the groove 130. In this invention, the first rotating shaft 310 of the spiral guide assembly 3 and the rotating assembly 1 rotate synchronously and in the same direction. That is, the rotating assembly 1 rotates counterclockwise downwards, and the spiral curved surface of the groove 130 and the spiral tile blank 11 also rotate counterclockwise downwards. The first rotating shaft 310 also rotates counterclockwise synchronously, driving the moving part 320 to move forward in a straight line, thereby driving the rotary grinding head 441 to move forward in a straight line. Relative to the rotating assembly 1, with the rotating assembly 1 as a reference, the movement trajectory of the rotary grinding head 441 is spiral upwards. Of course, the rotating assembly 1 can rotate clockwise, but the clockwise rotation case will not be discussed in detail. This arrangement ensures that the rotary grinding head 441 grinds the inclined surface of the spiral tile blank 11 into a spiral curved surface. Figure 5 The diagram shows the shape of the spiral tile ground by the apparatus provided in this embodiment, namely, the arc surface 1101, the plane 1102, and the spiral curved surface 1103. To allow for a more intuitive observation of the spiral curved surface of the spiral tile... Figure 6 and Figure 7The overall shape of a spiral tile, formed by grinding multiple spiral tiles together in this example, is shown. Therefore, the implementation of this invention requires the coordinated action of a rotary grinding head 441 (moving linearly), a spiral tile blank 11 (moving in a circular motion), and a spiral curved surface of the groove 130. Specifically, regarding the groove 130 on the rotating assembly 1 with one side being a spiral curved surface, if the groove 130 is a recessed groove carved into the rotating assembly 1, then one side is a spiral curved surface. If the rotating assembly 1 includes a rotating shaft and an annular column 120 mounted on the rotating shaft, then the groove 130 can be set on one side of the annular column 120, and that side can be set as a spiral curved surface. In this embodiment, the spiral curved surface is set as a spiral upward curve, i.e., the lower groove 130 is wider and the upper groove 130 is narrower. It can also be set as a spiral downward curve, as long as the function of this embodiment is achieved. For the helical lead assembly 3, a lead screw is used in the specific setting. The moving part 320 and the first rotating shaft 310 are screwed together. The rotation of the first rotating shaft 310 causes the moving part 320 to make linear motion.

[0045] It should be noted that in this embodiment, the spiral surface of the neodymium iron boron spiral tile is processed, but the processing device provided in this embodiment can be applied not only to neodymium iron boron spiral tiles, but also to other materials that need to be ground into a spiral surface.

[0046] In one specific embodiment, the spiral tile processing device is configured such that the first rotating shaft 310 and the rotating component 1 rotate synchronously and in the same direction as follows: a driving wheel 7 is provided at one end of the rotating component 1, and a driven wheel 8 is provided at one end of the first rotating shaft 310. The driving wheel 7 and the driven wheel 8 are connected by a synchronous belt 9.

[0047] In the above specific embodiment, in order to ensure that the first rotating shaft 310 and the rotating assembly 1 rotate synchronously and in the same direction, a synchronous belt 9 is used to connect the first rotating shaft and the rotating assembly 1 to ensure absolute synchronization and unidirectional rotation. Specifically, preferably, the helical lead assembly 3 is located directly below the rotating assembly 1. The helical lead assembly 3 can also be located on one side of the rotating assembly 1, either to the lower left or lower right, as long as it facilitates the installation of the grinding device 4.

[0048] In one specific embodiment, the spiral tile processing device includes a rotating assembly 1 comprising a second rotating shaft 110 and an annular column 120 disposed on the second rotating shaft 110, with a groove 130 disposed on the annular column 120; the fixed station 2 comprises an arc-shaped plate 210 and an arc-shaped cover 220, the arc-shaped plate 210 being fixed on the annular column 120, an arc-shaped groove 240 being disposed on one side of the arc-shaped plate 210 for placing the spiral tile blank 11 to be processed, and the arc-shaped cover 220 being fixed on the arc-shaped plate 210 and covering the arc-shaped groove 240 for fixing the spiral tile blank 11 to be processed; wherein, a through hole is disposed on the other side of the arc-shaped plate 210, and an adjusting bolt 230 is disposed in the through hole to prevent the spiral tile blank 11 to be processed from moving into the arc-shaped groove 240 during the grinding process.

[0049] In the above specific embodiment, for the annular column 120 set on the second rotating shaft 110, in order to facilitate fixing the annular column 120, the annular column 120 is set with a larger diameter in the middle and smaller diameters at both ends, and the groove 130 is set on the annular column 120 with a larger diameter in the middle. For the arc plate 210 and arc cap 220 of the fixed station 2, their curvature should be adapted to the curvature of the annular column 120. In this embodiment, the arc length of the inclined surface of the spiral tile to be processed is less than the arc length of the groove 130, so as to leave enough space to adjust the feed position of the rotating grinding head 441 before grinding begins. Since this embodiment processes the inclined surface of the spiral tile blank 11 into a spiral curved surface, the size of the arc groove 240 can only ensure that the spiral tile blank 11 will not move in the circumferential arc direction, but cannot guarantee that the spiral tile blank 11 will not move in the left-right direction. In the left-right direction, i.e., the axial direction of the second rotating shaft 110, the arc groove 240 cannot be perfectly matched with the size of the spiral tile blank 11, and the setting of the arc-shaped pressure cap 220 can only ensure that the spiral tile blank 11 will not fall out of the arc groove 240. Therefore, in order to ensure that the spiral tile blank will not move during the grinding process, a through hole is provided on the other side of the arc plate 210, and an adjusting bolt 230 is set in the through hole. This can both fix the spiral tile blank and adjust the position of the spiral tile blank 11 in the arc groove 240 according to the amount of inclined surface to be ground. Preferably, there are two through holes, but there can also be three or four. The number of through holes can be specifically set according to the arc length of the spiral tile blank 11 to be processed. Figures 2-4 As can be seen from this, in order to make the fixed workstation and the spiral curved surface of the tank compatible, both the arc plate and the arc cover are set to an arc shape that is wider at the top and narrower at the bottom.

[0050] In one specific embodiment, the spiral tile processing device is provided with a swing arm 5 on the second rotating shaft 110, and the second rotating shaft 110 is reciprocated by the swing arm 5.

[0051] In the above embodiment, by providing a swing arm 5 on the second rotating shaft 110, the reciprocating rotation of the second rotating shaft 110 can be easily controlled. In a specific configuration, the swing arm 5 can also be automatically controlled by a crank-slider mechanism to set the reciprocating time and number of reciprocations, thereby achieving the purpose of automatic control. Regarding the specific configuration of automatic control, existing technologies can be used, and this embodiment will not elaborate further.

[0052] In one specific embodiment, the grinding device 4 of the spiral tile processing apparatus includes:

[0053] The guide slide 410 is fixed on the moving part 320 of the spiral lead assembly 3;

[0054] The X-axis dovetail slide 420 is fixed on the guide rail slide 410, and the sliding direction of the X-axis dovetail slide 420 is perpendicular to the moving direction of the moving component 320.

[0055] The Y-axis dovetail slide 430 is fixed on the slide cover of the X-axis dovetail slide 420, and the sliding cover of the Y-axis dovetail slide 430 moves in a direction parallel to the moving direction of the moving component 320.

[0056] A high-speed grinding device 440 is provided on the sliding cover of the Y-axis dovetail slide 430, and a cylindrical rotary grinding head 441 is provided at the end of the high-speed grinding spindle of the high-speed grinding device 440.

[0057] In the above embodiment, the guide slide 410 is fixed on the moving component 320 and moves with the moving component 320. The X-axis dovetail slide 420, mounted on the guide slide 410, includes a dovetail slide base and a dovetail cover. A Y-axis dovetail slide 430 is mounted on the cover of the X-axis dovetail slide 420, and the high-speed grinding device 440 is mounted on the cover of the Y-axis dovetail slide 430. The X-axis dovetail slide 420 and the Y-axis dovetail slide 430 can have their feed rates controlled by servo motors to achieve automatic control. This embodiment does not specifically limit the specific configuration of the automatic control; existing technologies can be used.

[0058] In one specific embodiment, the spiral tile processing device further includes two first support members 10. The spiral guide assembly 3 and the rotating assembly 1 are rotatably disposed between the two first support members 10, with the spiral guide assembly 3 located below the rotating assembly 1. The end of the first shaft 310 of the driven wheel 8 and the end of the second shaft 110 of the driving wheel 7 both pass through one of the first support members 10 and are then connected by the synchronous belt 9.

[0059] In the above embodiment, the helical lead assembly 3 and the rotating assembly 1 are fixed to the first support members 10 on both sides by bearings. Positioning the helical lead assembly 3 below the rotating assembly 1 allows for convenient installation of the grinding device 4, resulting in a rational structural layout of the entire device and saving space.

[0060] In one specific embodiment, the spiral tile processing device further includes a base plate 6, on which the two first support members 10 are fixed. Two cylindrical support rods 610 are also provided on the base plate 6, with the axial directions of the two cylindrical support rods 610 parallel to the axial direction of the first rotating shaft 310. Movable sliders 620 are provided on each of the two cylindrical support rods 610, allowing the sliders 620 to slide on the cylindrical support rods 610. The sliders 620 are fixedly connected to the bottom surface of the guide rail slide 410 to support the guide rail slide 410. The sliders 620 both allow the guide rail slide 410 to move linearly with the moving component 320 and provide support for the guide rail slide 410.

[0061] In one specific embodiment, the spiral tile processing device further includes a fixing plate, the bottom surface of which is fixed to one end of the guide rail slide 410, and the side surface of which is fixed to the moving component 320. The fixing plate facilitates the connection between the guide rail slide 410 and the moving component 320.

[0062] Another embodiment of the present invention provides a method for processing spiral roof tiles, applied to the aforementioned spiral roof tile processing apparatus, comprising:

[0063] Step 1: Obtain the spiral tile blank 11 to be processed, which has two arc-shaped surfaces, two planes and two inclined surfaces. The two inclined surfaces need to be processed into spiral curved surfaces.

[0064] Step 2: Place the spiral tile blank 11 in the arc groove 240, then fix the arc pressure cap 220, and rotate the adjusting bolt 230 so that the inclined surface to be processed of the spiral tile blank 11 is exposed on the spiral curved surface of the groove 130.

[0065] Step 3: Adjust the X-axis dovetail slide 420 and the Y-axis dovetail slide 430 to adjust the feed of the rotary grinding head 441, so that the rotary grinding head 441 is located next to the helical surface of the groove 130 and at an appropriate distance from the helical surface, to ensure that the inclined surface to be processed is ground into a helical surface.

[0066] Step 4: Rotate the swing arm 5, rotate the rotating component 1, and rotate the second rotating shaft 110. The first rotating shaft 310 is driven to rotate synchronously through the synchronous belt 9, causing the moving component 320 to make linear motion, which in turn causes the guide rail slide 410 to make linear motion, thereby causing the rotary grinding head 441 to make linear motion. The rotary grinding head 441, which makes linear motion, the spiral tile blank 11, which makes circular motion, and the spiral curved surface of the groove 130 cooperate with each other to grind the inclined surface of the spiral tile blank 11 into a spiral curved surface.

[0067] Step 5: After one of the inclined surfaces is ground into a spiral surface, rotate the spiral tile blank 11 180 degrees and reinstall it. Then, following the order of steps 2 to 4, grind the other inclined surface into a spiral surface.

[0068] In the above embodiments, for obtaining the neodymium iron boron spiral tile blank 11, firstly, the neodymium iron boron powder is subjected to near-net-shape pressing and sintering to achieve a tile-shaped blank; then, it is processed by a continuous forming grinding machine to achieve the finishing of the two arc-shaped curved surfaces and two planes of the spiral tile, reaching the required dimensional and positional accuracy in the design; finally, a multi-wire cutting device, such as... Figure 8 As shown, the dashed line is cutting line 12. A special positioning fixture is used to machine the beveled surface at the end, thus obtaining... Figure 9 The spiral tile blank 11 shown has bevels at both ends, which are the bevels used for grinding the spiral surface.

[0069] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the invention will be readily apparent to those skilled in the art.

[0070] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.

8. A method for processing spiral roof tiles, applied to the spiral roof tile processing apparatus according to any one of claims 1 to 7, characterized in that, include: Step 1: Obtain the rough blank of the spiral tile to be processed, which has two arc-shaped surfaces, two planes and two inclined surfaces. The two inclined surfaces need to be processed into spiral curved surfaces. Step 2: Place the spiral tile blank in the arc-shaped groove, then fix the arc-shaped pressure cap, and rotate the adjusting bolt to expose the spiral curved surface of the groove body on the inclined surface to be processed of the spiral tile blank. Step 3: Adjust the X-axis dovetail slide and the Y-axis dovetail slide to adjust the feed of the rotary grinding head, so that the rotary grinding head is located next to the helical surface of the groove and at an appropriate distance from the helical surface, to ensure that the inclined surface to be processed is ground into a helical surface; Step 4: Rotate the swing arm, rotate the rotating component, rotate the second rotating shaft, and drive the first rotating shaft to rotate synchronously through the synchronous belt, so that the moving part makes linear motion, drives the guide rail slide to make linear motion, so that the rotary grinding head makes linear motion. The rotary grinding head that makes linear motion, the spiral tile blank that makes circular motion, and the set groove spiral curved surface cooperate with each other to grind the inclined surface of the spiral tile blank into a spiral curved surface. Step 5: After one of the inclined surfaces is ground into a spiral surface, rotate the spiral tile blank 180 degrees and reinstall it. Then, following the order of steps 2 to 4, grind the other inclined surface into a spiral surface.
