Steady rest operation guidelines and maintenance
Steady rest options supplied by Milltronics are designed for toolroom use or limited
production applications only. High speed, high production applications extend beyond
the scope of a simple steady rest.
When using the steady rest, adhere to the following guidelines:
1. The steady rest bearings must ride on a turned surface. Out of round workpieces
including unfinished bar stock cause uneven load on the bearings resulting in
shortened bearing life.
2. Avoid over-tightening the support bearing adjustments. Over-tightening causes
binding and shortened bearing life. Use your best judgment to avoid binding.
3. Avoid over-speeding the bearings. The bearings are rated to 9,000 rpm. Note
that the bearing rotation speed will exceed the spindle rpm whenever the
workpiece diameter being supported is greater than the bearing diameter.
4. Before each use, ensure the bearings are greased and they rotate smoothly.
See grease specification below.
5. Avoid direct coolant spray on and around the bearings to avoid washing the
grease out of the bearings.
Failure to comply with these guidelines voids the factory warranty.
