Category: Machine Shop

Summary: Supporting long workpieces.

Steady rests are lathe accessories used to provide support to long, slender workpieces during machining. These workpieces are prone to bending or deflection under the cutting forces, which can lead to inaccuracies and poor surface finish.

Function: Steady rests act as an external support, preventing the workpiece from vibrating or deflecting away from the cutting tool. They typically have adjustable jaws or fingers that contact the workpiece and keep it centered and stable.

Use: Steady rests are crucial for:

    * Turning long shafts or rods.

    * Machining slender parts that are susceptible to bending.

    * Performing operations like drilling or threading on long workpieces.

Types: 

    Fixed steady rests: Mounted to the lathe bed and provide stationary support.

    Follower rests: Attached to the lathe carriage and move along with the cutting tool, providing support close to the cutting point.
