Steady Rest, When You Need One And What To Look For
What is a Steady Rest
A Steady Rest is a Workholding Device generally consisting of 3 rollers that close inorder to engage and clamp a round diameter on a workpiece to provide support.
Steady Rest, When You Need One And What To Look For
When the inherent strength of a work piece is not sufficient to resist the force of the cutting tool usually to support long rods or shafts.
To support the end of a work piece without a tailstock engaged. Usually to allow for 2nd Operation end machining to be completed on the work piece. These operations may include facing , ID drilling or boring and possibly adding a bolt hole pattern on the end of the work piece.

Hose Track
Steady Rest, When You Need One And What To Look For
• Always ensure the steady rest is properly aligned to the machine spindle centerline.
• Use proper type (ISO 46) and intervals of lubrication for the Steady Rest and rollers.
• Use the lowest hydraulic pressure that gives you desirable results.• Always turn the part prior to engaging the steady rest. Turn the steady rest band(s)
in an area where you can get a good round diameter free of chatter. You might need to start closer to the headstock or tailstock and work your way to the center of the part.
• Do not engage the Steady Rest on a part rotating at higher speeds as this can develop flat spots on the rollers.
• Always ensure the steady rest rollers and chip guards are in good working condition.

What is the Maximum Diameter to be Clamped? What is the Minimum Diameter to be Clamped? What is the Length of the Part(s)? Do you require more than 1 steady rest? Is this a Fixed or Traveling Steady Rest Application? How will the Steady Rest be Mounted in the Machine?
• Tailstock Way Mounted with Manual or Automatic Positioning• Turret Mounted with or without Indexing Capability
Will the Steady Rest Support a Straight and/or Tapered Part?• Cylindrical Bearings Preferred?• Spherical Bearings Preferred?
Manual Grease or Automatic Oil Lubrication Preference? Is the Steady Rest Interface available from the OEM?
• Needs to be Installed and Operational prior to Installation. What is the Delivery Requirement?
