The CNMG inserts are Double-sided 80° rhombic inserts, positive rake angle that varies along the edge to negative in order to prevent chipping. Special design reduces vibrations. CNMG inserts are the great options for carbon and alloy steel, stainless steel and high temp alloys. The CNMG inserts can be used for roughing, semi-finishing and finishing proportionate to the sizes, grades and the nose radius of the insert
General Technical Information:
The effects of clearance angle:
The main function of clearance angle is to reduce the friction between the clearance face of tool and the surface of workpiece. When the rake angle is fixed, larger clearance angle can increase the sharpness of cutting edge, reduce cutting forces and friction, and then achieve higher surface quality. However, if clearance angle is too large, the strength of cutting edge would decrease. Also, heat can’t be diffused easily and serious abrasion would occur, reducing tool life.
The principle of choosing clearance angle: Choose small clearance angle if friction is not serious.
1. What are the differences between hard metal and heavy metal?
In the metalworking world, these two terms have different meanings. Hard metal much more refers to the cemented carbide which is mainly used in cutting tools. And heavy metals are the metals with high atomic weight or density. In general, it refers to heavy metal alloys which are sintered composite materials containing 90% or more tungsten.
2. How many employees in your company?
The total number of our employees is 1800. Notably, 25% of the total employees are the R&D personnel which allow us to develop more and more new products to our customers.
