The broaching machine elevator, which is the part of the machine that moves the broach above the workholder, then lowers the broach through the workpiece. Once through, the broaching machine's puller, essentially a hook, grabs the pilot of the broach. The elevator then releases the top of the follower and the puller pulls the broach through the ...
There are three main steps in broaching a keyway: First, the workpiece is set on the arbor press and the bushing is placed in the opening of the workpiece. Next, the broach is inserted and pushed through, cutting the keyway. Finally, shims are placed between the bushing and the broach to achieve the correct depth necessary for the key. [6]
Shaper tool slide, clapper box and cutting tool Shaper with boring bar setup to allow cutting of internal features, such as keyways, or even shapes that might otherwise be cut with wire EDM. In machining, a shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to
Some machines will cut to a depth on the Y axis and index the rotary table automatically. The largest gears are produced on these machines. Other operations such as broaching work particularly well for cutting teeth on the inside. The downside to this is that it is expensive and different broach sticks are required to make different sized gears.
Broaching can refer to two operations, linear broaching, where a multi toothed tool is pressed through a hole to cut a desired shape (e.g. a spline, square, or hex shape) or along a surface by taking increasingly larger cuts by the increasing sized teeth of the broach; or rotary broaching, where a drafted tool is rotated in a special toolholder ...
Other ways to generate the hex socket include linear broaching and rotary broaching. Broaching the heads with a linear broach is essentially the metalworking analog of mortising wood with a mortising machine; a hole is drilled and then the corners are broached out. This operation often leaves little telltale curled chips still attached at the ...
