What is the PCD&PCBN Cutting Tools?
The PCD Cutting Tools is that the PCD (Polycrystalline diamond) is brazed onto the Tungsten Carbide Carrier to form an insert. While, the PCBN (Polycrystalline Cubic Boron Nitride) Cutting Tools is that the PCBN is brazed onto the Tungsten Carbide Carrier to form an insert. During cutting, only the cutting bit is utilized, however, the cutting base is also an indispensable element.
Diamond Vitrified Grinding Wheel for Grinding the PCD&PCBN Cutting Tools
At present, the Grinding Processes of the PCD &PCBN Cutting Tools mainly adopts the Diamond Vitrified Grinding Wheel, which mainly because the Diamond Vitrified Grinding Wheel possesses the following excellent
performances during grinding:
1. high grinding efficiency, and not easy to heat and block ;
2. excellent wear-resistance, and less abrasive grains consumption. Especially most obvious in the condition of grinding the very hard and poor tenacity work-piece;
3. small grinding force, and low grinding temperature;
4. high grinding precision, and good surface quality for work-piece;
5. good shape keeping;
The Common Parameters of the Grinding Wheel in the PCD&PCBN Cutting Tools Industry
The grit size is the indispensable element for the grinding wheel production. ‘HEROHOME’ is very familiar with the Grinding Wheel in PCD&PCBN Cutting Tools Industry. According to our experience, the grit size of the Diamond Vitrified Grinding Wheel mainly includes the D6, D9, D15, D20, and D35. Also the shape is comparatively fixed: 6A2, 12A2 and 1A1. As for the specification of the outer diameter of the Grinding Wheel in this industry, is from 100 to 350 mm.
Different Grinding Procedures for PCD&PCBN Cutting Tools
When we are planning to produce a piece of grinding wheel, we need to know the detailed grit size first. At this time, we may ask our clients directly or ask them what’s their requirement for the surface roughness of
the work-piece? In the PCD & PCBN Cutting Tools Industry, according to the client’s need for the surface roughness of the PCD Cutting Tools or PCBN Cutting Tools, our engineers can recommend the suitable grit size
for you. Please see the following chart:
| Grinding procedures | Suitable grit size | Surface roughness of the work-piece (μm) |
| Coarse Grinding | 230/270#-325/400# | 0.05 |
| Semi-fine Grinding | M20-M40 | 0.02 |
| Fine Grinding | M5-M10 |
0.005
