Cemmented Carbide Drilling Cutting Parameters

Cemmented carbide drilling cutting parameters - cutting speed (VC), unit is m / min, is determined by the peripheral speed, cutting speed with spindle speed (n) to get. The spindle speed is represented by the number of revolutions per minute. In a turn, the drill circumference of π × Dc, Dc is the drill diameter. The drilling machining parameter of the cutting speed will change, which depends on the cross section of a cutting edge on the drill. From the drill center to the circumference, its speed is from zero to maximum. Recommended cutting speed is the highest speed of circumference.
