Hydraulic steady rest :
Arms steady rest is an apt design for holding long slender cylindrical jobs. This steady can be specially used in CNC turning centers by it’s compatibility of programming &interfacing with the cnc system. Arms steady rests are designed to get optimum result in accurate turning of long slender jobs .Arms steady rests are designed for getting high productivity by eliminating rejection and the setting time of manual steady rests.
Arms steady rests are designed according to the customers’ requirement of job sizes. These are hydraulically operated steady rests.Side mounted and rear mounted cylinder designs are also available according to the bed design of lathes
Arms steady rests are at par to the international standard by manufacturing & design yet very competitive in price ! These steady rests are dimensionally interchangeable with any other similar models available in the market.
- 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.
