The specific parameters of the drilling and milling machine for drilling diameter (the tensile strength of 50-60kg/mm2 steel is 40 mm), spindle stroke is 250 mm, 200 mm spindle spindle box travel speed range 31.5-1400 rev/min, spindle feed rate 0.056-1.8 mm/rev.
How much speed depends on what material to cut. As well as the actual use, we should consider the spindle power, the machine tool and the handle of the beating. Up to 200 meters per minute, usually aluminum, or magnesium alloy.
The cutting force of drill milling cutter is based on the sharp knife and drilling the drill, milling cutter cutting force should not be calculated, but its capacity is fixed, speed, it has high speed, medium speed and low speed. Spindle speed 31.5-1400 rev/min, that is to say, in a minute, the main shaft to turn 1400 laps, the speed in which you say machine tools should be high speed, and it each into the level of 0.056-1.8 mm/rev, that is, 0. 5 millimeters to 1. 8 mm,
