Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grinding machines, in particular to a working method of a peripheral grinding machine and the peripheral grinding machine. BACKGROUND

[0002] The peripheral grinding machine is a machine tool for grinding the periphery of a workpiece by rotating and feeding a main grinding wheel, and is mainly used in the superhard blade grinding industry.

[0003] The main grinding wheel is mainly made of diamond. Diamond particles of the same granularity and diameter in irregular shapes are sintered on the grinding wheel base by a binder, so that the micro surface of the grinding wheel is uneven. Microscopically, the diamond particles protrude from the grinding wheel to form "peaks" and remain sharp. When the main grinding wheel grinds the workpiece, the material particles falling off the workpiece during grinding will be adsorbed on the main grinding wheel, blocking the gap between the diamond particles, making the micro surface of the grinding wheel flat, and thus the grinding wheel is no longer sharp and the grinding force decreases. The current mainstream method for dealing with the clogging of the grinding wheel is to install a cleaning wheel on the grinding machine. A cleaning wheel made of large-particle white corundum is used to grind against the main grinding wheel during the grinding process of the main grinding wheel to remove the clogging on the surface of the grinding wheel. This grinding wheel cleaning and flattening method consumes the main grinding wheel and the dressing wheel at the same time. When the dressing wheel is used to clean the main grinding wheel, the consumption of the main grinding wheel is more than 5 times that of the main grinding wheel when grinding the blade. The main grinding wheel is severely wasted during cleaning, and the cost of grinding the blade is high. SUMMARY

[0004] Therefore, the present application provides a working method of a peripheral grinding machine and the peripheral grinding machine to solve the problem of high consumption of the main grinding wheel when the dressing wheel is used to clean the main grinding wheel, severe waste of the main grinding wheel during cleaning, and high cost of grinding the blade.

[0005] According to an aspect of the present application, a working method of a peripheral grinding machine is provided for controlling the peripheral grinding machine to grind a plurality of first blades in turn. The working method of the peripheral grinding machine comprises: a grinding step of controlling the peripheral grinding machine to grind the first blade and obtaining the maximum grinding force of the peripheral grinding machine on the first blade; a comparison step of comparing the grinding force with a predetermined value; when the maximum grinding force is less than the predetermined value, the grinding step is performed; when the maximum grinding force is greater than or equal to the predetermined value, a cleaning step is performed, and after the cleaning step is completed, the grinding step is performed; The cleaning step comprises: controlling the peripheral grinding machine to grind a second blade, the hardness of the second blade being greater than the hardness of the first blade.

[0006] Preferably, the working method of the peripheral grinding machine further comprises: after the cleaning step is completed, obtaining an inscribed circle diameter of the second blade; comparing the inscribed circle diameter with a predetermined range, when the inscribed circle diameter is greater than an upper limit value of the predetermined range, the second blade can continue to be used to perform the cleaning step; when the inscribed circle diameter is within the predetermined range, replacing another second blade for performing the cleaning step.

[0007] Preferably, the working method of the peripheral grinding machine further comprises: replacing another second blade for performing the cleaning step after the cleaning step is completed.

[0008] Preferably, the first blade is a PCBN blade, and the second blade is a PCD blade.

[0009] Preferably, the first blade is a cermet blade, and the second blade is a PCBN blade.

[0010] Preferably, the first blade is a cemented carbide blade, and the second blade is a PCBN blade.

[0011] Preferably, the first blade and the second blade are both PCBN blades, and the CBN content of the first blade is less than the CBN content of the second blade.

[0012] Preferably, the peripheral grinding machine uses a ceramic-based diamond grinding wheel.

[0013] Preferably, the peripheral grinding machine uses a resin-based diamond grinding wheel.

[0014] According to another aspect of the present application, a peripheral grinding machine is provided, which performs the working method of the peripheral grinding machine described above.

[0015] The working method of the peripheral grinding machine of the present application comprises: a grinding step of controlling the peripheral grinding machine to grind a first blade and obtaining a maximum grinding force of the peripheral grinding machine on the first blade; a comparison step of comparing the grinding force with a predetermined value; when the maximum grinding force is less than the predetermined value, performing the grinding step; when the maximum grinding force is greater than or equal to the predetermined value, performing a cleaning step, and after the cleaning step is completed, performing the grinding step; wherein the cleaning step comprises: controlling the peripheral grinding machine to grind a second blade, the hardness of the second blade being greater than the hardness of the first blade.

[0016] In the peripheral grinding machine, when the above-mentioned working method of the peripheral grinding machine is performed, after the grinding of a first blade is completed, the maximum grinding force applied by the grinding wheel to the first blade during the grinding of the first blade is compared with a predetermined value, and when the maximum grinding force is less than the predetermined value, the grinding wheel of the peripheral grinding machine is less worn, and the grinding of the next first blade can be continued. When the maximum grinding force during the grinding of the first blade is greater than or equal to the predetermined value after the peripheral grinding machine is operated to complete the grinding of a first blade, the peripheral grinding wheel is more worn, and the cleaning step is performed, so that the peripheral grinding machine grinds a second blade. Since the hardness of the second blade is greater than that of the first blade, this causes extrusion when the second blade contacts the grinding wheel, so as to extrude the dull particles on the grinding wheel, thereby making the grinding wheel sharp. After the cleaning step is completed, the grinding wheel can continue to be used for grinding the first blade. In this way, the second blade is used to clean the grinding wheel, and compared with cleaning the grinding wheel using white corundum, the grinding wheel is less worn when the grinding wheel is cleaned using the second blade, thereby reducing the cleaning cost of the grinding wheel. At the same time, when the second blade cleans the grinding wheel, the grinding wheel also processes the second blade, thereby improving the utilization rate of the grinding wheel.

[0028] According to an aspect of the present application, there is provided a working method of a peripheral grinder, comprising: Figure 1 As shown, the working method of the peripheral grinder is used to control the peripheral grinder to grind a plurality of first blades in sequence, and the working method of the peripheral grinder comprises: a grinding step of controlling the peripheral grinder to grind the first blade and obtaining a maximum grinding force of the peripheral grinder on the first blade; a comparison step of comparing the grinding force with a predetermined value; when the maximum grinding force is less than the predetermined value, performing the grinding step; when the maximum grinding force is greater than or equal to the predetermined value, performing a cleaning step, and after the cleaning step is completed, performing the grinding step; wherein the cleaning step comprises: controlling the peripheral grinder to grind a second blade, the hardness of the second blade being greater than the hardness of the first blade.

[0029] In the working method of the peripheral grinding machine of the present application, after the grinding of a first blade is completed, the maximum grinding force exerted by the grinding wheel on the first blade during the grinding of the first blade is compared with a predetermined value, and when the maximum grinding force is less than the predetermined value, the grinding wheel of the peripheral grinding machine is less worn, and the grinding of the next first blade can continue. When the maximum grinding force during the grinding of the first blade is greater than or equal to the predetermined value after the peripheral grinding machine runs to complete the grinding of a first blade, the peripheral grinding wheel is more worn, and a cleaning step is performed so that the peripheral grinding machine grinds a second blade. Since the hardness of the second blade is greater than that of the first blade, this causes the second blade to form extrusion when it contacts the grinding wheel, so as to extrude the dull particles on the grinding wheel, thereby making the grinding wheel sharp. After the cleaning step is completed, the grinding wheel can continue to be used for grinding the first blade. In this way, the second blade is used to clean the grinding wheel, and compared with using white corundum to clean the grinding wheel, the grinding wheel is less worn when the second blade is used to clean the grinding wheel, thereby reducing the cleaning cost of the grinding wheel. At the same time, when the second blade cleans the grinding wheel, the grinding wheel also processes the second blade, thereby improving the utilization rate of the grinding wheel.

[0030] Optionally, the predetermined value can be 1.1 times the maximum grinding force exerted by the grinding wheel of the peripheral grinding machine on the first blade during the grinding of the first blade.

[0031] In addition, when the second blade used for cleaning the grinding wheel is ground to the inscribed circle diameter within a predetermined range, the grinding of the second blade is completed, and the second blade can also be used, that is, the grinding wheel can also be ground during the cleaning process, thereby improving the utilization rate of the grinding wheel.

[0032] Further, the working method of the peripheral grinding machine further comprises: After the cleaning step is completed, the inscribed circle diameter of the second blade is obtained; The inscribed circle diameter is compared with a predetermined range, and when the inscribed circle diameter is greater than the upper limit value of the predetermined range, the second blade can continue to be used to perform the cleaning step; When the inscribed circle diameter is within the predetermined range (i.e. the inscribed circle diameter is less than or equal to the upper limit value of the predetermined range and greater than or equal to the lower limit value of the predetermined range), another second blade is replaced to perform the cleaning step.

[0033] The predetermined range is a range that the second blade needs to satisfy when the second blade is ground as a regular blade to be ground. After performing the cleaning step once, the inscribed circle diameter of the second blade is judged. If the inscribed circle diameter of the second blade is still greater than the upper limit of the predetermined range, the second blade does not meet the processing requirements at this time, and the second blade can still be used to perform the cleaning step. If the inscribed circle diameter of the second blade is within the predetermined range after performing the cleaning step once, the second blade meets the processing requirements at this time, and the processing of the second blade is completed, and the second blade can no longer be used to perform the cleaning step.

[0034] Optionally, different materials of the second blade can be selected for different materials of the first blade. The predetermined range can be different when different materials of the second blade are used.

[0035] In addition, when the peripheral grinding machine grinds the first blade, different grinding programs are selected for the first blade to meet the grinding requirements of the first blade of different materials. At the same time, the grinding program of the first blade can be used to grind the second blade in the cleaning step, or a special grinding program can be selected for the material of the second blade.

[0036] When the grinding program of the first blade is used to grind the second blade, because the hardness of the second blade is greater than the hardness of the first blade, when the first grinding of the second blade is completed, the inscribed circle diameter of the second blade is still greater than the upper limit of the predetermined range, and the second blade can perform multiple cleaning steps at this time. In addition, because the hardness of the second blade is greater than the hardness of the first blade, the cleaning step using the grinding program of the first blade will not directly reduce the inscribed circle diameter of the second blade from greater than the upper limit of the predetermined range to less than the lower limit of the predetermined range. That is, when a second blade performs a cleaning step to make the inscribed circle diameter of the second blade only slightly greater than the upper limit of the predetermined range, the second blade performs a cleaning step again to make the inscribed circle diameter of the second blade within the predetermined range, thereby completing the processing of the second blade.

[0037] When the grinding program of the second blade is used to grind the second blade, the second blade performs a cleaning step to make the inscribed circle diameter of the second blade within the predetermined range at this time. A piece of second blade can only perform a cleaning step once, and a new second blade needs to be replaced when the cleaning step is performed again.

[0038] Optionally, different materials of the second blade can be selected based on the material of the first blade.

[0039] When the first blade is a PCBN (Polycrystalline Cubic Boron Nitride) blade, the second blade can be a PCD (Polycrystalline Diamond) blade, at this time, the peripheral grinding machine adopts a ceramic-based diamond grinding wheel, because the hardness of the PCD blade is greater than the hardness of the PCBN blade, which makes the PCD blade can push away the particles on the peripheral grinding machine due to the dullness of grinding PCBN blade, so that the ceramic-based diamond grinding wheel remains sharp. When the PCD blade cleans the grinding wheel, the grinding wheel also processes the PCD blade, thereby improving the utilization rate of the grinding wheel. In this implementation form, when the ceramic-based diamond grinding wheel is used to grind the PCD blade alone, the ceramic-based diamond grinding wheel can only grind 200 pieces, when the ceramic-based diamond grinding wheel is used to grind the PCBN blade alone, the ceramic-based diamond grinding wheel can only grind 1300 pieces, if the working method of the peripheral grinding machine of the application is adopted, the ceramic-based diamond grinding wheel can grind 1200 pieces of PCBN blade and 200 pieces of PCD blade, which improves the utilization rate of the ceramic-based diamond grinding wheel.

[0040] When the first blade is a metal ceramic blade, the second blade is a PCBN blade, at this time, the peripheral grinding machine adopts a resin-based diamond grinding wheel, because the hardness of the PCBN blade is greater than the hardness of the metal ceramic blade, which makes the PCBN blade can push away the particles on the peripheral grinding machine due to the dullness of grinding metal ceramic blade, so that the resin-based diamond grinding wheel remains sharp. When the PCBN blade cleans the grinding wheel, the grinding wheel also processes the PCBN blade, thereby improving the utilization rate of the grinding wheel. In this implementation form, when the resin-based diamond grinding wheel is used to grind the PCBN blade alone, the resin-based diamond grinding wheel can only grind 300 pieces, when the resin-based diamond grinding wheel is used to grind the metal ceramic blade alone, the resin-based diamond grinding wheel can grind 3300 pieces. If the working method of the peripheral grinding machine of the application is adopted, the resin-based diamond grinding wheel can grind 200 pieces of PCBN blade and 3200 pieces of metal ceramic blade, which improves the utilization rate of the resin-based diamond grinding wheel.

[0041] In the case that the first blade is a cemented carbide blade and the second blade is a PCBN blade, the peripheral grinding machine adopts a resin bond diamond grinding wheel. Since the hardness of the PCBN blade is greater than that of the cemented carbide blade, the PCBN blade can push away the particles on the peripheral grinding machine that are dulled by grinding the cemented carbide blade, so that the resin bond diamond grinding wheel remains sharp. When the PCBN blade cleans the grinding wheel, the grinding wheel also processes the PCBN blade, thereby improving the utilization rate of the grinding wheel. In this implementation form, when the resin bond diamond grinding wheel is used to grind PCBN blades alone, only 200 pieces can be ground, and when the resin bond diamond grinding wheel is used to grind cemented carbide blades alone, 30,000 pieces can be ground. If the working method of the peripheral grinding machine of the present application is adopted, the resin bond diamond grinding wheel can grind 200 pieces of PCBN blades and 30,000 pieces of cemented carbide blades, thereby improving the utilization rate of the resin bond diamond grinding wheel.

[0042] Alternatively, the first blade and the second blade are both PCBN blades, and the CBN content in the first blade is less than the CBN content in the second blade. In this case, the peripheral grinding machine adopts a ceramic bond diamond grinding wheel. Since the hardness of the second blade with high CBN content is greater than that of the first blade with low CBN content, the second blade with high CBN content can push away the particles on the peripheral grinding machine that are dulled by grinding the first blade with low CBN content, so that the ceramic bond diamond grinding wheel remains sharp. When the second blade with high CBN content cleans the grinding wheel, the grinding wheel also processes the second blade with high CBN content, thereby improving the utilization rate of the grinding wheel.

[0043] In the case that the first blade is a PCBN blade with a specification model of SNGN090408, the second blade is a PCD blade with the same specification model, and the grinding wheel of the peripheral grinding machine is a ceramic bond diamond grinding wheel, the peripheral grinding machine performs the cleaning step using the program for grinding PCBN blades to grind the PCD blade. When the peripheral grinding machine performs the working method of the peripheral grinding machine of the present application to grind the PCBN blade, the process is as follows: (1) Perform the grinding step to make the peripheral grinding machine grind the first PCBN blade; During the grinding of the first PCBN blade, the maximum grinding force exerted by the grinding wheel on the first PCBN blade is less than a predetermined value. After the grinding of the first PCBN blade is completed, the grinding wheel is slightly dirty and the surface is slightly black, but the grinding wheel can still be used.

[0044] (2) Perform the grinding step to make the peripheral grinding machine grind the second PCBN blade; During the grinding of the second PCBN blade, the maximum grinding force exerted by the grinding wheel on the second PCBN blade is greater than the predetermined value, and then the cleaning step needs to be performed; (3) performing the cleaning step to make the peripheral grinding machine grind the PCD blade; The PCD blade is ground by the program for grinding the PCD blade, and when the grinding is completed, the inscribed circle diameter of the PCD blade is greater than the maximum value in the predetermined range, the PCD blade can be used again to perform the cleaning step.

[0045] After the cleaning step is completed, the grinding step can be performed again to grind the PCBN blade, and the maximum grinding force applied by the grinding wheel to the PCBN blade in the grinding step is compared with a predetermined value, and based on the comparison result, the grinding step or the cleaning step is selected to be performed, and so on. When the PCD blade performs the cleaning step until the inscribed circle diameter of the PCD blade is within the predetermined range, the PCD blade can no longer be used to perform the cleaning step, and another PCD blade is replaced to clean the grinding wheel when the cleaning step is performed again.

[0046] In the first blade is a PCBN blade with a specification model of SNGN090408, the second blade is a PCD blade with the same specification model, the grinding wheel of the peripheral grinding machine is a ceramic-based diamond grinding wheel, and when the cleaning step is performed by the program for grinding the PCD blade to grind the PCD blade, the peripheral grinding machine performs the working method of the peripheral grinding machine of the present application to grind the PCBN blade as follows: (1) performing the grinding step to make the peripheral grinding machine grind the first PCBN blade; (2) performing the grinding step to make the peripheral grinding machine grind the second PCBN blade; (3) performing the cleaning step to make the peripheral grinding machine grind the PCD blade; The PCD blade is ground by the program for grinding the PCD blade, and when the grinding is completed, the inscribed circle diameter of the PCD blade is within the predetermined range, the PCD blade can no longer be used to perform the cleaning step, and another PCD blade is replaced to clean the grinding wheel when the cleaning step is performed again.

[0047] After the cleaning step is completed, the grinding step can be performed again to grind the PCBN blade, and based on the comparison result, the grinding step or the cleaning step is selected to be performed, and so on.

[0048] According to another aspect of the present application, a peripheral grinding machine is provided, which performs the working method of the peripheral grinding machine described above. The grinding wheel of the peripheral grinding machine is cleaned by grinding the second blade. Compared with cleaning the grinding wheel using a white corundum cleaning wheel, the grinding wheel is less worn when the grinding wheel is cleaned using the second blade, thereby reducing the cleaning cost of the grinding wheel. At the same time, when the second blade is used to clean the grinding wheel, the grinding wheel is used to process the second blade, thereby improving the utilization rate of the grinding wheel.

[0049] In addition, the peripheral grinder of the present application no longer needs to modify the related components of the grinding wheel installation and no longer needs to modify the grinding wheel, thus simplifying the structure of the peripheral grinder and reducing the cost of the peripheral grinder.

[0050] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
