FAQ

How about the speed of the drill bit and the feed of the cutter in the machining center?

1, if I first drill with D13 bit (S600, F80, Q5), and the rest of all milling cutter hole2, casting and steel parts almost turn, the speed can be faster. After 28 of the hole points, use 28 bit S300, F50, Q3. directly3, 35r6 direct spiral down, layer below 0.5-0.8, S1500, F2000-3000

How do the front and back angles of the drill change? How does it affect drilling?

The drill rake sometimes do some changes, for example, in the drill brass material and an insulating plate material, easy to drill bar knife, the cutting edge of the drill to grind 0 degrees before the angle, so the bit will not tie the knife; in addition, some of the more hard materials in the drill bit, if it is before angle, cutting edge strength is not enough, high temperature generated when the drill cutting, easy to burn out or cutting edge jump edge, then the bit to grind out before the rake angle is 0 degrees, it is helpful to enhance the strength of the drill edge. Protect the cutting edge of the bit so that the drill can go smoothly.

Small bit drilling, drilling machine speed is fast or slow?

The two cutting edges should be the same length, and the cutting edge is usually between 8~12 degrees. Do not cut the cutting edge even lower than the back angle, so that the drill can not be drilled. In addition, the drill bit should be slightly sharpened so that the axial resistance of the bit during drilling will be reduced, so that the drill can save a lot of effort when drilling down.

How can we change an ordinary drill bit into stainless steel?
