Arms self centering steady rests are specially designed to get the optimum result in automatic holding of cylindrical jobs. Arms steady rests provide best centering accuracy& repeatability in microns .Arms self centering steady rests can be used as replacement of any other models of self centering steady rests due to interchangeability in mounting dimensions . Arms steady rests are hydraulically operated and can be interfaced with the cnc system, save the setting time and give better productivity. The special rollers used in Arms steady rests help for running the job in high rpm and give best surface finish . The body & parts of arms steady rests are well heat treated and provide good life.
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.
