What is a keyway bushing?
Keyway broaches, keyseating broaches, keyway broach shims, and keyway broach bushings are used to machine keyways, splines, and other irregular shapes into a hole in metalworking tasks.
How do you design a shaft key?
Key dimensions: Parallel keys are most commonly used. The key and key seat cross section are ISO standardized. The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion.
Which chisel is used for cutting keyways?
Cross-cut or cape chisels: These are used for cutting keyways, grooves, and slots.
What is a keyway broach set?
Cut and bore keyways in gears, pulleys, and shafts. Using the G9774 18-Piece HSS Keyway Broach Set is the quickest and easiest way to produce a keyway. A keyway is a slot that is cut on a gear, pulley, or shaft which covers the other half of the key projecting out of the shaft in which it is seated.
What is a keyway broach set used for?
Keyseating broaches are used for producing keyway-shaped holes in a workpiece. They are ground to precision keyway tolerances and designed for AF series machines. Keyway broaches are used for producing keyway-shaped holes in a workpiece. They may be used with shims if the depth cannot be broached in a single pass.
How do you dimension a keyway?
In the English system, it is standard practice to dimension keyways. The hub keyway is dimensioned by its width and depth on the shaft – keyway sides. Referencing Figure 1, the keyway dimension is W x T1. Unless otherwise specified, the shaft keyway is assumed to be standard.

How do you put a broach in a bushing?
Liberally lube up the broach with your favorite cutting oil and and insert the broach into the slot in the bushing. The first quarter or so should slid in easily before the teeth engage with the part. Align the part with the gap in the press and ensure the broach is straight up and down.
How do you use an arbor press broach?
Align the part with the gap in the press and ensure the broach is straight up and down. Then apply even pressure, ensuring that the part is not tilting or rocking off the arbor press work surface. In aluminum it requires little effort. Be prepared to catch the broach as it reaches the end of its stroke-it may fall out.
