Diamond coated tools

Diamond coated tools with diamond coated tools directly in the carbide CVD method (K type carbide) or ceramic layer deposited on the substrate 1 ~ 25μm diamond films,

no cleavage plane isotropic. Figure 3 (b). Film coated tool hardness of 9800 ~

10000HV. High thermal conductivity, thermal conductivity at room temperature up to 2000W · m-1 · K-1, while the carbide thermal conductivity is only 80 ~ 100m-1 ·

K-1. Diamond CVD method may be coated to any complex shape of the tool, which is not owned by the polycrystalline diamond

The most significant advantage.
Cubic boron nitride (PCBN) cutting tools cubic boron nitride (PCBN) is the second synthetic diamond that appears after the second inorganic superhard materials, its

slightly inferior to diamond hardness, good thermal stability, heat resistance up to 1400 ~ 1500 degrees, the heat resistance than diamond (700 to 800 degrees) Quite

Almost twice as high. Cubic boron nitride (PCBN) cutting tools is mainly suitable for processing a variety of ferrous metals and their alloys; most suitable for a

variety of hardened steel (carbon tool steel, bearing steel, tool steel, high speed steel) pearlitic gray cast iron (vanadium-titanium iron) chilled cast superalloys

(nickel-based alloys

Cobalt-based alloys) and surface coating welding processing. Has a long life and reduce the number of tool changes, compensation down the time spent for NC machine

tools and automated production line efficiency can be more fully exploited, can change the traditional machining way (ie, before quenching with a tool

Wheels for roughing and finishing after quenching method), which can be on a CNC machine before quenching after quenching turning (turning instead of grinding), with

good economic benefits.
