What is the lathe steady rest?follow rest?
When machining long, slender workpieces like shafts or tubes on a lathe, two specialized fixtures are crucial to prevent deflection and vibration: the “steady rest”and the “follow rest”. The “steady rest”(or center rest) is a “fixed support”clamped directly to the lathe bedways. It provides “rigid, stationary support” at a specific point along the workpiece's length, typically between the headstock and tailstock. This is essential for operations like boring the center of a long tube or turning sections far from the chuck, preventing bending. In contrast, the “follow rest” attaches to and “moves with the lathe carriage”. Positioned directly behind the cutting tool, it provides “traveling support” immediately adjacent to the cut. This dynamically counteracts the radial pressure of the tool on the workpiece, especially critical during threading, finishing passes, or turning very thin sections where the tool force could push the material away. While the steady rest stabilizes the workpiece at a fixed location, the follower rest actively follows the tool to maintain support precisely where cutting forces are applied. Both are indispensable for achieving accuracy, good surface finish, and safety when working with long, flexible components, often used separately or sometimes together on critical jobs.
Key Differences Summarized:
Feature | Steady Rest (Center Rest) | Follow Rest |
Mounting | Fixed to lathe bed | Mounted on the carriage |
Movement | Stationary | Moves with the carriage/tool |
Position | Supports at a fixed midpoint | Supports directly behind tool |
Primary Use | Preventing mid-span bending | Countering tool pressure |
Typical Ops | Boring, turning mid-sections | Threading, finishing, thin work |
Access | Can allow internal machining | Obstructs side access |
