Difference between steady rest and follower rest in lathe machine
Answers
A Lathe machine is a basic machine tool that is used for removing metals from a work piece in order to give it a desired shape and size by operations like grooving, turning, knurling etc. When the tool deflects the workpiece, the accurate dimensions defer and it affects the quality and efficiency of the turning.
Therefore, two applications have been designed as a remedy for the lathe turning deflection problem. They are Steady rests and Follower rests. They help in holding the work piece steadily during turning.
Steady Rests – These rests are mounted on the lathe bed and do not move with the lathe. Although they limit the supporting cut length, they ensure concentricity. It provides the support while turning to reduce vibration.
Follower rests – attach to the lathe component that holds the tool, also called as the "saddle" and move along or “follow” the lathe. It is fastened to the carriage and moves along with the cutting tool. It is used when the flexible shafts are threaded.
