Milling cutters are one of the indispensable tools for milling machine. Only by choosing the right milling cutter, can the ideal machining result be achieved.
1. Milling cutter material
1) High-speed tool steel has good cutting performance, the appropriate cutting speed of 16 ~ 35 m/min. Used in the manufacture of more complex shape of the cutter.
2) Carbide steel has good wear resistance, poor cutting performance at low speed and poor manufacturability. Cutting speed is 4~7 times higher than that of high speed tool steel. Milling machine cutting tools are used for high speed cutting and hard material cutting. Usually, the carbide blade is fixed on the cutter body by welding or mechanical clamping.
The cutter is essentially a multi-blade standard tool consisting of several single-blade tools whose main and secondary cutting edges are distributed on the outer or outer surface according to their type and structure.
2. Milling cutter classification
There are many ways to classify miller cutters. According to the milling cutter installation method is divided into two kinds of hole milling cutter and handle milling cutter.
The common hole milling cutters are cylindrical milling cutter, three face milling cutter (integral or inlaid type), saw blade milling cutter, modulus milling cutter, angle milling cutter and arc milling cutter (convex arc or concave arc) and so on. The milling cutters with holes are used in horizontal milling machines for machining flat surfaces, straight grooves, cuts, teeth and arc grooves (or spiral grooves).
Handle milling cutter according to the shape of the handle is divided into two kinds of straight handle or taper shank. Commonly have a tooth face (end) cutter, end mills, keyway cutter, T-slot cutter and dovetail slot cutter, as shown. Handle Mills are used in vertical milling machines for machining flat, stepped surfaces, grooves and keyways, T-slots or dovetail slots.
