Self Centering Steady Rest

image

Arms Hydraulic steady rests are very compact in design for the automatic holding for round jobs.The design of arms hydraulic steady rests enables the saving of setting time and eliminating the rejection of jobs. These steady rests can be programmed through the cnc system. Arms steady rests give good centering accuracy & the repeatability. Various models are available as the side mounted cylinders,rear mounted cylinders etc. according to the bed design of the turning machine& the job sizes.Arms hydraulics steady rest can be used as travelling steady rest also. Arms hydraulic steady rests can be used for replacing any other models due to the mounting dimensional standard suitably selected to match the international standard.The special rollers used in the steady rest gives good surface finish to the job . Proper heat treatment and the lubrication system give better life for the steady rest.



Application
  • Machining of Long Slender Shafts
  • Automatic Holding of Jobs In CNC Turning Machines.
  • Crank Shaft Machining
  • For Grinding Applications
Salient Features
  • The Steady Rest Can Be Used For Any Machine Including CNC Lathes With a Suitable Bracket
  • The Steady Can Also Be Used As A Travelling Steady Hence No Need Of A Follower Rest !!!
  • Repeatability Is Within 5 Microns !!!!!!!!
Working principle

The steady rest consists of 3 arms assembled in a steel body with rollers at the arms for holding the work piece. The centre one brings the other two arms in a circular movement to hold the center of the work piece .This helps to get the repeatability and consistency in getting the centering accuracy The centre arm is operated by a hydraulic cylinder. The job holding rollers are lubricated through centralized lubricating system.
