Henan JCB can provide high-quality ceramic diamond grinding wheels for rough and fine grinding of PCB circuit boards, V-Cut knives, woodworking saw blades and other PCD tools. Ceramic diamond grinding wheels have better mechanical strength, long service life, fast cutting speed, good heat resistance, sharp cutting, high grinding efficiency, and are not easy to accumulate heat and blockage during the grinding process. It solves the problem of low efficiency, poor edge quality, and chip accumulation in the process of processing circuit boards, which leads to burrs in the finished product, reducing costs for customers. Under normal wear, V-CUT tools must be ground 0.25mm to 0.35mm each time, that is, the diameter is reduced by 0.5mm to 0.7mm. A new tool needs to be reground about 5 times when it is worn and the gap is not greater than 0.35mm.

Advantages of Henan JCB ceramic diamond grinding wheel
-The multi-porous structure makes the passivated diamond easier to fall off, reduces grinding resistance, prevents the generation of vertical stripes on the workpiece and improves the surface processing quality
-Perfect dimensional tolerance control, suitable for CNC and manual tool grinders
-Good self-sharpening, high grinding efficiency, high wear resistance, and low abrasive consumption
-The use of ceramic binder can make PCD/CBN tools achieve good surface finish and avoid edge chipping, thereby reducing the scrap rate and improving the grinding accuracy of PCD/CBN tools
-The service life of ceramic bond grinding wheel is several times that of resin bond grinding wheel and can be easily trimmed online
Application fields of diamond V-CUT tools
1. It can be used to cut double-sided copper-clad PCB circuit boards, various glass fiber FR2 boards, glass fiber FR4 boards, copper-clad boards, aluminum substrates, copper substrates, high TG boards, halogen-free boards, iron substrates, CEM1, CEM3 material circuit boards.
2. It is also suitable for cutting V-groove processing of PCB circuit boards in other industries.
Why choose diamond V-Cut knife to process PCB circuit boards?
- The hardness of polycrystalline is as high as 8000HV. Diamond is one of the hardest materials on earth. The product has good wear resistance, which can reach 50 times that of cemented carbide. - Long service life: Taking FR-4 board as an example, the normal operation is to cut 30,000-40,000 meters at a time. When the use status is good, the service life can reach 50,000-60,000 meters.
- PCB diamond V-CUT knife is used for PCB circuit board V groove
- The knife distance can be automatically adjusted according to the thickness of the circuit board to reduce tool wear.
- The V groove operation has high precision, one-time forming, and longer service life.
- It is very suitable for processing aluminum substrates and suitable for dry cutting operations.
- Relative wear resistance improves the stability of line width.
