Broach refers to the tool for the majority of heavy-duty tool and fine sharpener, which is mainly installed in broaching machine.
Broach is a kind of high productivity and high precision multi thread tool. It can broach various shapes of internal surface (e.g. circular hole, polygonal hole and various spline holes) and external surface (e.g. indentation at the root of the blades of steam turbine, external gear, semicircle orifice of connecting bar and rabbet surface etc.) The broach used to broach the internal surface is called inside broach, and the broach used to broach the external broach is called broach. The majority of the broaching forces are tensile forces, however some are compression forces. The broach under compression force is called broach, and the broach under thrust is called pushing broach. Considering the stability, pushing broach is relatively short.
Advantages of broach cutting tools:
• Short machining time and high efficiency.
• Good surface roughness of the machining surface(≒12.5S).
• If the axle of irregular shape and straightforward multi shapes are in the same axle, it can also be machined.
• High machining precision, small deviation
• The machining method is economic, and the operator who is not skilled can also work.
• It will be just all right is the axle of irregular shape and straightforward multi shapes are in the same axle and direction.
