Laser-cut PCD-tipped inserts can provide a smooth cutting edge for a mirror-like finish and longer insert life.
Principle of laser cutting PCD
It is a laser beam with very high density of energy star irradiates on the surface of polycrystalline diamond, and part of the light energy is absorbed by the surface and converted into heat energy. The temperature in the local area of the irradiated spot rises rapidly to tens of thousands of degrees, which makes the polycrystalline diamond material locally melt or even vaporize and form a pit.
By comparing the machining principles of WEDM, HSS grinding and laser cutting, the advantages of laser cutting are as follows:
1. Smooth surface finish
At present, when using WEDM or high speed steel disc processing pcd will cause diamond grains will crack, which will destroy the structure and affect the cutting performance of PCD material.
Laser cutting directly acts on the diamond grains and link materials for processing with process high purity and coarse particles character , it can obtain the cutting edge fillet radius<15um, perfect cutting effect without breaking edge.
2. Complicated forms and tight tolerances
The tool used in the rounded edge processing of the iPhone phone shell is the PCD forming tool. It takes 30 minutes when using the ball milling cutter is used for the spindle processing,
After the forming PCD milling cutter is used for processing, every time It only takes 20 seconds. Greatly improve the efficiency and reduce the cost.
3. Smaller cutting radius edge
Laser cutting technology is a non-contact processing technology, cutting quality star is good, the minimum edge radius of the blunt circle can reach between 3-5um. 
4. less influence on edge heat.
The principle of laser cutting is to make the workpiece in its focus position by high power density of laser spot irradiation, the instantaneous high temperature of tens of thousands of degrees, the process of instantaneous gasification, the thermal impact of the cutting process is small.
PDC cutters are widely used for gas,oli drilling,coal minning etc.Grinding procession will directly influence the quality od PCD cutter.Moresuperhard provide diamond grinding wheel for grinding different parts of pdc cutter like surface grinding,external grinding wheel ,double-sided grinding disc and centerless grinding wheel.
In the grinding industry, ceramic diamond double-end grinding discs have attracted much attention for their high efficiency and high precision. In order to help newcomers quickly master the core knowledge in this field, Moresuperhard specially invited Jim, a sales expert in double-end grinding discs, to conduct a systematic training. From basic concepts to practical applications, this training content is full of practical content. Of course, in order to test the learning results, Jim assigned homework to everyone. The students' answers are all very good, which are summarized as follows for everyone to learn and refer to.
