How to choose CNC milling cutter?
Milling cutter is a kind of rotary cutter with one or more teeth, which is used for milling. When working, each cutter tooth cuts off the spare quantity of the workpiece in turn. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and workpieces on milling machines. According to work needs, milling cutters can be divided into cylindrical milling cutters, face milling cutters, end milling cutters, etc. Surface milling cutter is mainly used for plane processing on vertical milling machine, end milling machine or gant
Analytical toolholder method techniques
In the machining center handle, cutting tool on the machine tool chip, we need to consider not only the speed of processing, more also have to understand its chip principle. And the chip coefficients. This is like the importance of the way the cutting edge leaves the workpiece in machining. The blade clearance may be reduced somewhat by material remaining near the end of the blade. When the chip detaches from the workpiece, a transient tensile force is generated along the front face of the blade, often resulting in burrs on the workpiece. This te
