Tool material for alloy or high speed steel, workpiece material is aluminum alloy or below HRC30 carbon steel, I want to use milling instead of boring, I wonder if I can ask the experienced brothers to advise me.
Milling machine milling round hole is no problem, but look at your machine tools, what precision, but also depends on the size of the machining round hole. The size of the round hole is not the same as the requirement of accuracy.If it is corrected using a laser tracker tool, machine tool precision can reach 0.01MM is no problem.Now the high-precision CNC machine tools to achieve 0.01MM basic, no big problem
Why do you choose milling for such a small diameter hole? The milling efficiency is low, the precision is poor, and the processing cost is high.H7 hole milling is generally impossible to achieve, the machine tool to take the arc interpolation, in fact, go by numerous small straight line, forming an integral circle, so the diameter accuracy is mainly guaranteed by machine tools.Processing aluminum alloy and processing carbon steel difference is huge, general aluminum alloy finish is no problem, because aluminum alloy can be very high wire speed, carbon steel is a little bit.Also depends on the hole depth and diameter of the tool diameter ratio, small diameter milling cutter too deep, easy to break, the election of the big diameter, not good chip.In a word, milling is not allowed if conditions permit
