Aanalysis on end mill cutter

The main cutting edge end mill is a cylindrical surface, the end surface of the cutting edge of the blade is deputy. No central blade mill cutter at work can make along the axial feed motion. In accordance with national standards: milling cutter diameter of 2-50 mm, can be divided into two kinds of coarse teeth and fine teeth. Straight shank diameter range 2-20, 14-50 for the taper shank diameter range.

Standard end mills with coarse teeth and two fine. Coarse teeth end mill bits for 3 to 4 teeth, helix angle β bigger; a fine-tooth milling cutter teeth 5 to 8, the helix angle β smaller. Material part of high-speed steel cutting, steel shank 45.
There are many shapes cutter, general milling and CNC milling machine slot with a straight profile, the boring and cutting disc machining center cavity, core, curved shape outline available.

Cutter broadly divided into:

1. Flat cutter, fine-milling or roughing, milling grooves, remove large amounts of rough, a small area of the horizontal plane or contour finishing;

2. The end mill cutter, for surface finishing and semi-finishing; knife could face a steep fine milling / straight wall of the small chamfer.

3. round nose cutter, make minor changes in the surface, less a small recessed area, relatively flat area more rough milling.
