Lnitial drilling, to recommend the use of cutting conditions in the middle range, followed by(in accordance with wear) to adjust the cutting parameters to achieve the best cutting effect.
He above cutting parameters is for 2D, 3D drilling toools. For 4D drilling tools, the cutting parameters need to decrease 15%.
Cooling mode using only cold outside, cutting speed should be reduced by 10%. It must adopt inner cooling mode for austenitic stainless steel machining. Drilling on the slope or the parts have pre-drilling hole or intersection hole. The drilling feedrate must decrease to 1/3 of the recommended data.
