Cutter selection

Only correct type and cutting edge may do a good job for milling work. Popular end mills include flat cutter, side cutter, face milling cutter, milling cutter, end mill, sawing, and milling cutter. Its characteristics is that many teeth and flutes on one milling cutter, some end mills with only two or three teeth; some cutters are with considerable numbers of teeth. Hence end mill is called as multi-teeth cutters.

There are many types of cutters and a variety of classification methods as below:

Classify by material:

  1. High-speed steel cutters:for general purposes, the most widely used.
  2. Carbide cutter:for high speed cutting.
  3. Non-ferrous metal casting alloy cutter:suitable for heavy cutting.

Classify by the way of grinding wheel:

  1. Contour cutter.
  2. Type cutter.

Classify by tool installation:

  1. Spindle cutter device:set cutter by use of the tool axis, which with a hole in the center of milling cutter, and used in horizontal milling machine.
  2. Shank type milling cutter:cutter body with straight shank or taper shank, it needs to be fixed by a chuck or socket for installation.
  3. Face Mills:This cutter is with a short cutter shaft, it needs to be settled by cutter shaft device then set on the spindle of milling machine directly for installation.

Classify by cutter structure:

  1. Overall cutter:body and cutting edge made by the same material as a whole, generally adopt high-speed steel.
  2. Brazed cutter:cutting blade made with carbide, the body is high carbon steel, combined by brazed joint.
  3. Welding blade cutter: cutting blade made with high carbon steel or tool steel, high-speed steel, ontology Ministry both to weld joints.
  4. Inlay cutter:blade screwed on the body, you can remove it to grind or replace, mostly used in face milling cutter of big diameter.
