State chip area and originate in the shaft that top terminates at alloy cutter bar., can be to useless by the design at the top of the alloy cutter bar of taper
Bits provide enough resigning chambers, are easy to scrap to be discharged from corresponding chip area.
Preferably, the cross section of the chip area is in V-shape.Scrap can be avoided to be overflowed from the both sides of chip area, it is ensured that useless
Bits are only capable of reaching the region specified along chip area.
Preferably, the cross section of the PCD blades is in a rectangular trapezoid, and the cross section of the alloy blade is in sector.Alloy
In the integrally formed alloy cutter bar of blade, in fan-shaped more practicality, the cross section of PCD blades is determined by diamond characteristic.
It is as further improvement of the utility model, in order to solve because PCD blades cause milling cutter because not prison welding is solid
The side and the side of alloy blade of the PCD blades in the problem of can not processing, the utility model are welded and fixed, described
Upper surface at the top of the bottom surface of PCD blades and alloy cutter bar is welded and fixed；The solder side of PCD blades has two end faces, it is ensured that
The firmness connected between PCD blades and alloy cutter bar.
It is as further improvement of the utility model, the upper surface at the top of the bottom surface of the PCD blades and alloy cutter bar
Solder side be an inclined-plane, the inclined-plane forms an angle with horizontal plane shape.Increase knife bar intensity；Save material.
Preferably, a portion of the side of the alloy blade and a portion of the side of PCD blades are welded
Fixed, to reserve processing cutting edge, what alloy blade connected with PCD blades is partially larger than 1/2 alloy blade so that solder side is not
Easily come off.
Preferably, the alloy blade, concentricity≤0.001 of PCD blades；The bounce of the alloy blade, PCD blades
Amplitude≤0.01.Stable when concentricity and bounce, machined surface finish can be lifted significantly.
