Quality Keyway Broaching

Keyseating is a machining process in which internal shapes and forms are cut using a reciprocating, single-point cutting tool - similar to the shaping process.

 

Keyseats Can Be Done with Precision and Speed

For a key to function, the shaft and rotating machine element must have a keyway and a keyseat. There are three main types of keys: Sunk, Saddle, and Tangent Round, and Spline keys. We have the capabilities to do them all with precision and speed.

 

1 Keyway = 1 Minute! Even if you make just one keyway per week, we have affordable, adaptable solutions to fit your needs at a reasonable price.

Also for: Splines, Internal gears, Long bores, Blind holes.

Ask for a broaching keyway demo without any obligation. Please don't hesitate...we can come to your workshop, discuss technical issues and broach a keyway to compare times. Seeing is believing.

  • Sunk Key: A key that fits into keyways in both the shaft and the secured member in machinery. It includes rectangular, square, parallel sunk, Gib-head, Feather and Woodruff keys.
  • Rectangular Sunk Key: The rectangular key is rectangular in shape. They are used for shaft diameters over 6.5 inches (170 mm) or when the wall thickness of the mating hub is a concern.
  • Square Sunk Key: The square sunk key has the same thickness and width.
  • Gib-head Sunk Key: The shape of gib-head key is similar to rectangular key but has head at one end. The reason behind using head is to provide some ease at the time key removal.
  • Square Sunk Keys: Square keys are used for smaller shafts
  • Parallel Sunk Keys: Parallel keys are the most widely used. They have a square or rectangular cross-section.
