Product Description

Diamond cutting tool grinding equipment

    Ultra precision machining mainly includes ultra precision cutting, ultra precision grinding, and polishing, and its machining accuracy can reach sub micron level shape accuracy and nanometer level surface roughness. Especially when using precision natural single point diamond cutting tools to process non-ferrous and non-metallic metals, ultra smooth machining surfaces can be directly cut, eliminating manual precision machining processes such as grinding. This not only saves time, but also improves machining accuracy and surface quality.

    Diamond cutting tools have advantages such as high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low coefficient of thermal expansion, and low affinity with non-ferrous metals. It can be used for precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high silicon aluminum alloys, and other ductile non-ferrous metal materials. There are various types of diamond cutting tools, with significant differences in performance. There are significant differences in the structure, preparation methods, and application fields of different types of diamond cutting tools.

    The wear of diamond cutting tools generally occurs in the following situations:
Mechanical wear, adhesive wear, reverse transformation (phase change) wear, chemical wear, diffusion wear, bonding wear, micro cracking wear, abnormal wear.

    Wear forms: wear on the front blade surface and wear on the back blade surface.

    Diamond cutting tools are mainly used for ultra precision mirror processing of copper and copper alloys, precious non-ferrous metals such as gold, silver, and rhodium, as well as special parts, such as recording camera disks, optical flat mirrors, polyhedral mirrors, and quadric mirrors. But its crystal anisotropy makes cutting tools expensive. The performance of PCD depends on the content of diamond grains and cobalt, and the tool life is 10-500 times that of hard alloy (WC matrix) tools. Mainly used for turning various non-ferrous metals such as aluminum, copper, magnesium and their alloys, hard alloys, highly wear-resistant fiber plasticizers, metal matrix composites, wood and other non-metallic materials. The cutting speed, feed rate, and cutting depth during cutting depend on the material and hardness of the workpiece.

Blade grinding is mainly divided into the following processes:
(1) Clean thoroughly with alcohol cotton.
(2) Measurement:Blades with large chipping and excessive wear (exceeding the grinding limit) are considered incapable of grinding.The ones with small chipping and low wear shall be grouped for grinding according to the drawing requirements, and the dimensional tolerance of each group for grinding shall be within 0.05mm.
(3) Grinding: Grinding worn tools that are grouped according to size.
(4) Testing: Measurement using a universal display instrument.

Grinding plan:
1. Determine the grinding limit and scrapping standards according to customer requirements;
2. Check if the blade has significant chipping or significant wear;
3. Develop grinding drawings and grinding processes based on the grinding limits and requirements provided by the customer;
4. According to the drawing requirements, group the blades according to size and perform batch grinding;
5. Measure with the Wangongxian instrument and store it for packaging after passing the inspection.

Grinding standards:
1. The blade body and blade head on the blade are clean and tidy, without any foreign objects, and the surface must not have cracks or rust, and the blade must not have any breakage;
2. The front and rear corners remain unchanged after grinding;
3. The thickness of each blade is consistent;
4. The radial runout tolerance of the blade diameter is 0-0.05mm;
5. The circular runout tolerance of the blade end face is 0-0.03mm;
6. Grinding feed: generally 0.002~0.01mm each time.


Precautions before grinding:
1. First, select a grinding wheel that uses PCBN tool for rough grinding of the cutting edge, and then program for rough opening wear (note that after the first tool is polished, be sure to self check first to avoid batch repairs or scrapping).
2. Select a grinding wheel suitable for PCBN tool edge precision grinding, and then program for precision grinding of the edge (note that the center of the tool must be adjusted between the first and second steps to avoid errors during mechanical arm clamping).
3. After the grinding is completed, the corresponding groups are placed in a box for testing (be careful not to damage the cutting edge when placing).
4. Tools with chamfers are transferred to the next process for chamfering, while tools without chamfers are transferred to final inspection.

Precautions during grinding:
1. Adjust the dynamic balance of the grinding wheel;
2. Adjust the feed rate positioning;
3. Self inspection of the first grinding tool chamfer. (1) Is the angle of the chamfer correct; (2) Is the size of the chamfer qualified.

The cutting edge of the tool plays an important role in the cutting process, and the improvement and enhancement of tool performance are of great significance for cutting. The passivation technology of tool edges has not yet received sufficient attention from people. Compared with the development of tool materials, tool structures, tool coatings and other technologies, the passivation technology of tool edges is relatively lagging behind. By conducting reasonable passivation treatment on the cutting edge of the tool, the tool life and cutting performance can be significantly improved, and the stability of the cutting system can be improved.

Measurement after grinding:
1. Check for burrs around the blade.
2. Check the cutting edge, the cutting edge must be smooth and free of any breakage.
3. The thickness of each set of cutting tools should be consistent.

Under a 60x magnification optical microscope, it is possible to finely detect whether the cutting edge of the tool has broken edges and whether the diamond particle size is uniform. Good cutting edge and uniform particle size can improve the machining accuracy of the tool and the surface quality of the workpiece, thereby significantly improving the cutting life and stability of the tool.
