What is a Broaching machine?

A broach tool is a machining machine that performs cutting using a tool called a broach that has a large number of cutting edges arranged in dimensional order. By pushing or pulling the brooch toward the workpiece using hydraulic pressure or other force, it is possible to perform a series of processes from roughing to finishing the inner and outer surfaces of the hole. It is a highly productive processing method and is widely used in the manufacture of automobile parts and mass production of various machine parts. On the other hand, the equipment cost is higher than general general-purpose machining equipment, so it is not suitable for small-quantity production.

Application of Broaching machine

Machining accuracy and productivity depend on the design and accuracy of the brooch. In addition, the cost is high, and it is not versatile because it is a dedicated tool for the specifications of the machined part. The brooch has a shank that serves as a grip when pulling out, and has a front guide that follows the pre-processing. There are rough cutting blades, medium finishing blades, and finishing blades that are subsequently processed, and there is a back guide.
