As everyone knows, however, a commodity only with just perfect, in order to achieve the best effect. So is the alloy bit. But what's the right way to use the alloy bit? Now, let's let you know the way to use the alloy bit correctly.

Because of the hard alloy is very precious, the correct use of the drill bit, make the best use of it, is a mechanical processing the responsibility of practitioners. How to use the hard alloy bit correctly mainly includes the following aspects:

, choosing the right machine tool carbide bit can be applied to CNC machine tools, machining centers and other large power and good quality machine tools, and ensure that the tool tips run TIR<0.02. The rocker drill and the universal milling machine are easy to avoid the early collapse of the hard alloy bit because of the low power and the poor precision of the spindle.2., choose the right tool holder, chuck, side pressure holder, hydraulic handle and thermal expansion knife handle, etc., but because the clamping force of quick change drill chuck is not enough, it will cause failure of bit slippage, so we should put an end to it.
3. correct cooling

(1) should pay attention to the direction of external cooling cooling combined, forming the upper and lower echelon, and possibly reduce angle and cutting tool.

(2) the internal cooling bit should pay attention to the pressure and flow, and should prevent the leakage of the coolant to influence the cooling effect.

4. correct drilling technology

(1) when the dip angle of the drilling surface is >8-10 degrees, it is not drillable. At <8-10 degree, the feed should be reduced to the normal 1/2-1/3.

(2) the feed should be reduced to the normal 1/2-1/3 when the dip angle of the drilled surface is >5 degrees.

(3) when drilling cross holes (orthogonal or oblique holes), the feed should be reduced to the normal 1/2-1/3.

(4) the 2 blade bit must not expand the hole.
