Difference between two edge milling cutter and three edge milling cutter

Different precision requirements:

1. The size of keyway milled by the two edge milling cutter can reach high accuracy, and the end face of the keyway milling cutter does not have a central hole, so it can directly feed down, instead of the common three edge milling cutter, which cannot directly feed down because of the central central hole.

2. The end mill with three edge milling cutter can not achieve the precision of keyway milling cutter. When the two milling cutters are milling, there is no difference in the three elements of milling.

What are the causes of the surface milling cutter lines?

Some people will find that when they are milling with the milling cutter, there will be tool lines, which not only affects the beauty of the workpiece, but also affects the quality of the workpiece. What is the reason for the tool lines? In fact, there are only the following reasons for the general surface milling cutter.

1. Size of feed per tooth

2. Microtrauma of cutting edge

3. Uneven feed speed

4. Mechanical vibration

Milling cutter

It is a rotary tool with one or more cutter teeth for milling. During operation, each cutter tooth will cut off the allowance of the workpiece intermittently. Milling cutter is mainly used for machining plane, step, groove, formed surface and cutting workpiece on milling machine.
