[0002] Ceramic materials have the characteristics of high melting point, high hardness, high wear resistance, and oxidation resistance. They are currently widely used in the fields of construction, medicine, electronics, aerospace, and daily life. Due to the high hardness and high wear resistance of ceramic materials, it is difficult to process them, and diamond grinding wheels are usually used for grinding. However, the existing diamond grinding tools are small in size, and when processing ceramic materials, the processing efficiency is low and it is easy to generate heat.

[0003] The patent with the announcement number "CN209903617U" discloses a "polycrystalline diamond integral cutting tool", which includes a tool holder and a polycrystalline diamond bit, wherein the polycrystalline diamond bit is welded to one end of the tool holder, and the polycrystalline diamond bit has a plurality of integrally formed blades at the end away from the tool holder, and the blades are circumferentially distributed on the outer peripheral side of the end of the polycrystalline diamond bit. However, the blade of the tool is covered at the end and periphery of the front end of the tool, resulting in an overall size of the blade being too large, which will cause a waste of resources.

[0004] To this end, our company has proposed a diamond multi-edge tool for processing ceramic materials. Summary of the invention

[0005] The purpose of the present invention is to provide a diamond multi-edge tool for machining ceramic materials, which can realize grinding of ceramic materials and improve machining efficiency.

[0013] Preferably, a second guide groove is formed on the end surface of the tool base, and the second alloy base has a second guide portion matched with the second guide groove.

[0014] Preferably, the first cutting edge and the second cutting edge are both arranged on the tool base in the form of alternating coarse teeth and fine teeth.

[0015] Preferably, the surfaces of the first and second cutting edges of the coarse tooth form are both plated with titanium nitride.

[0016] The beneficial effects of the present invention are: 1. Through the setting of the peripheral blade group, the holes of ceramic workpieces can be processed, and the chips can be discharged smoothly through the chip groove to ensure the processing quality.

[0023] The present invention is further described below in conjunction with the accompanying drawings.

[0024] Embodiment 1 like Figure 1 and Figure 2 As shown, a diamond multi-edge tool for processing ceramic materials includes a tool handle 3, a tool base 4 is provided at the lower part of the tool handle 3, and a peripheral blade group 5 is provided on the side wall array of the tool base 4. The peripheral blade group 5 includes a plurality of first cutting edges 52 for processing a workpiece, and a first chip groove 53 is formed between adjacent first cutting edges 52. The tool base 4 is made of high-strength steel or high-quality alloy steel, and has good rigidity, strength and wear resistance. The first cutting edge 52 is made of high-quality polycrystalline diamond or mixed-grained diamond composite sheet, and has high wear resistance and high impact toughness. It is fixed on the tool base 4 by vacuum welding, and a gap of 0.1-0.5 mm (i.e., the first chip groove 53) is maintained between each cutting blade to reduce the influence of thermal expansion and stress concentration, and also facilitate chip removal.

[0025] The upper part of the shank 3 is fixed with an ultrasonic horn 2 through a key connection, and the ultrasonic horn 2 is connected to the ultrasonic generator 1. The ultrasonic generator 1 transmits high-frequency vibration to the cutting edge through the ultrasonic horn 2, which is conducive to the removal of chips and improves the cutting performance. Through the intelligent control system, the ultrasonic vibration frequency and amplitude can be adjusted in real time to meet different processing requirements.

[0026] like Figure 2 and Figure 3As shown, the peripheral blade group 5 includes a first alloy base 51, and a plurality of first cutting edges 52 are arranged in parallel on the first alloy base 51. The extension direction of the first cutting edge 52 is consistent with the axial direction of the shank 3, which is convenient for processing the workpiece hole. The first alloy base 51 is a cemented carbide, and the first cutting edge 52 and the first alloy base 51 are bonded together at high temperature (1560°C) and high pressure (6GPa). The first alloy base 51 is connected to the tool base 4 through a first bolt 54. When the first cutting edge 52 is worn and affects the workpiece processing, the corresponding peripheral blade group 5 can be replaced without replacing the entire tool base 4 and the peripheral blade group 5 of the remaining parts, which greatly saves maintenance costs.

[0027] The side wall of the tool base 4 is provided with a first guide groove, and the first alloy base 51 has a first guide portion that matches the first guide groove. The peripheral blade assembly 5 can be assisted in positioning by the first guide groove, and can only be moved in a fixed direction, so as to facilitate its installation and fixation. In this embodiment, the first guide groove is a T-shaped groove, and in other embodiments, guide grooves of other shapes can also be used.

[0028] like Figure 1 and Figure 4 As shown, the end face array of the tool base 4 is provided with an end blade group 6, which includes a plurality of second cutting edges 62 for machining a workpiece, and a second chip groove 63 is formed between adjacent second cutting edges 62. The connection mode between the second cutting edge 62 and the tool base 4 and the size of the second chip groove 63 are consistent with the corresponding structures in the peripheral blade group 5. By setting the end blade group 6, the plane of the workpiece can be machined.

[0029] The peripheral blade group 5 and the end blade group 6 are arranged in a staggered manner to avoid blocking the chip removal process of the other party during the processing, thereby making the tool have higher cutting efficiency and better surface quality when processing ceramic materials. Appropriate cooling and lubricating fluids are used to reduce cutting heat and tool wear during the processing.

[0030] like Figure 4 and Figure 5 As shown, the end blade group 6 includes a second alloy base 61, a second cutting edge 62 is arranged on the second alloy base 61, the second cutting edge 62 and the two alloy bases 61 are bonded together at high temperature (1560°C) and high pressure (6GPa), the extension direction of the plurality of second cutting edges 62 is consistent with the diameter direction of the end face of the tool base, the second alloy base 61 is fan-shaped, the center of the fan-shaped circle is consistent with the center point of the end face of the tool base, the extension direction of the second cutting edge 62 is concentrated to the center of the fan-shaped circle, and the second alloy base 61 is connected to the tool base 4 through a second bolt 64. A second guide groove is provided on the end face of the tool base 4, and the second alloy base 61 has a second guide portion that cooperates with the second guide groove.

[0031] The first cutting edge 52 and the second cutting edge 62 are both arranged on the tool base 4 in the form of alternating coarse teeth and fine teeth to further improve the processing performance. The surfaces of the first cutting edge 52 and the second cutting edge 62 in the form of coarse teeth are plated with titanium nitride to improve the surface hardness, wear resistance and impact resistance of the tool head.

[0032] When the device is in use, the plane of the workpiece is processed by the end blade group 6, and the hole of the workpiece is processed by the peripheral blade group 5, thereby realizing all-round processing of the workpiece. In the prior art, workpieces with higher hardness such as ceramics are mainly ground by grinding wheels, which is inefficient. The device replaces the grinding wheel with a diamond blade, which can greatly improve the processing efficiency. The ultrasonic-assisted processing technology drives the tool to vibrate, and can also effectively reduce the cutting force, cutting temperature and facilitate chip removal, thereby improving the processing efficiency and surface quality. An intelligent control system can also be used to adjust the cutting parameters of the tool in real time according to the processing requirements, thereby further improving the processing efficiency and workpiece quality. The cutting force and temperature are monitored by sensors, and the ultrasonic vibration parameters and cutting parameters are adjusted in real time to ensure the stability and efficiency of the processing process.

[0033] In order to improve the impact toughness of the tool during high-speed machining while ensuring sufficient hardness, the first cutting edge 52 and the second cutting edge 62 of the device are made of polycrystalline diamond. The polycrystalline diamond is made by mixing 5% by volume of 1-3 micron WC powder with a certain volume ratio of 302 mixed particle size diamond micropowder and cobalt powder, and then sintering at high temperature and high pressure. The cutting edge is then subjected to a cobalt removal and pickling treatment, and the passivation effect is increased to improve the tool strength so that it meets the required performance.

[0034] Embodiment 2 like Figure 6 As shown, this embodiment is only used for processing holes in a workpiece, so only a peripheral blade group 5 is provided on the side wall array of the tool base 4, and the peripheral blade group 5 is detachably connected to the tool base 4 for easy replacement, and at the same time, the tool handle 3 is connected to the ultrasonic amplitude transformer 2 and the ultrasonic generator 1.

[0035] The other structures of this embodiment are consistent with those of the first embodiment.

[0036] Embodiment 3 Similar to the second embodiment, this embodiment is only used for processing the plane of the workpiece, so only the end blade group 6 is arranged on the end face array of the tool base 4. The end blade group 6 is detachably connected to the tool base 4 for easy replacement, and the tool handle 3 is connected to the ultrasonic horn 2 and the ultrasonic generator 1.
