Alloy drill the correct approach is how to use it?

Specializing in the production step drill manufacturers too good to let you know the proper use of alloy drill, because expensive carbide appropriate, accurate use of the drill, so that the best use is every practitioner's duty machining. How to accurately use carbide drill, the first includes the following aspects:

1. Selection of accurate machines carbide drills can be used in CNC machine tools, processing base power, steel and good tools, and should ensure that the tip runout TIR <0.02. The rocker drilling, versatile milling machine because less power, precision spindle poor, simple pre collapse damage resulting carbide drill should try to prevent.

2. Selection of accurate handle stretched spring chuck, side handle pressure, hydraulic handle, heat up the handle, etc. can be used, but because the quick-change drill chuck clamping force resulting not simply drill slippage and failure, should eradicate the use.

3. Accurate cooling
(1) cold outside combination should pay attention to the direction of cooling to form upper and lower echelon equipment, and to minimize the angle between the tool.
(2) cooling the drill should be aware that the pressure and flow rate, and should prevent the coolant leak affect the cooling effect.

4. Accurate drilling technology
(1) When drilling into the outer angle> 8-10 ° when, not drilling. <8-10 °, the feed should be reduced to the normal 1 / 2-1 / 3;
(2) When a diamond look inclination> 5 °, the feed should be reduced to the normal 1 / 2-1 / 3;
(3) When drilling through-holes (orthogonal or oblique bore hole), the feed should be reduced to the normal 1 / 2-1 / 3;
(4) 2 edge drill can not reaming.
