Cemented Carbide Broaches Types & Applications

Cemented carbide broaches species may be distinguished by machined surface portion, the structure and use of the broaches.

1.Distinguish cemented carbide broaches by different surface to be machined parts

Surface to be machined parts can be divided into within broaches and outside broaches. More common within broaches and outside broaches: round broaches, spline broaches, broaches Quartet broaches, keyway broaches and outside plane broaches.

2.Distinguish cemented carbide broaches by structures

Cemented carbide broaches are divided into integral broaches, welded broaches, assembly broaches and tipped broaches by structures. Cemented carbide broaches using for processing medium and small size surface are made of overall high-speed steel; Cemented carbide broaches machining large size, complex shape surface are made of assembled structures.

3.Distinguish cemented carbide broaches by different use methods

Cemented carbide broaches use methods can be divided into broaches, push knives and rotary broaches.

The push knives thrust working under. Push knives are mainly used for the correction hardness <HRC45, the amount of deformation <0.1mm machined hole. The push knives structures is similar with broaches, but the fewer number of teeth, the length is short, the front and rear shank portion is relatively simple. The rotary broaches torque acts through the rotational movement of the cutting of the workpiece.
