Hybrid Welding CBN Insert

Processed Material: Hardened steel, high strength cast iron, powder metallurgy, gray cast iron, powder metallurgical
Processing Methods: Finishing, semi-finishing and roughing.
Application: Brake disc, compressor flange, brake drum, gears, valve, bearing, roller, grinding roller, engine cylinder head, cylinder sleeve, cylinder block, etc.

Cubic Boron Nitride (CBN) is a superhard material whose hardness is second only to diamond. It not only has many excellent characteristics of diamond, but also has higher thermal stability and chemical inertness to iron group metals and their alloys.

This type of CBN insert has excellent wear resistance and long service life when finishing materials such as cast iron parts and high-hardness hardened parts.


When processing hardened steel with PCBN tools, the quenching hardness of the workpiece is required to be higher than 45~55HRC. When processing hard cast iron, as long as the hardness reaches the medium hardness level (45HRC), good processing results will be achieved. For example, the exhaust valve seat on the cylinder head of an automobile engine is made of high chromium alloy cast iron material containing copper and molybdenum, and its hardness is generally about 44HRC

Advantages

1. Wide applicability. Can meet rough, semi-finish and finish processing;
2. High fracture toughness. Suitable for continuous, weak intermittent, strong intermittent environmental cutting;
3. Many cutting edges and high inserts utilization;
4. High bending strength, suitable for high-speed cutting with large cutting depth;
5. Can process countersink or through-hole blades, making clamping more firm;
6. Welding temperature of 800 degrees, can withstand 650 degrees of cutting temperature without falling off;
7. This structure is recommended for hard steel processing;
8. Can be regrind, but limited times;
9. The corresponding clamping shank is very complete, which can directly replace the coated blade without replacing the shank.
