Frequently Asked Questions About Tailstocks
What is the function of tailstock?
Tailstocks are used to support long parts on a lathe or rotary table.
Is a tailstock necessary when using a CNC lathe to machine a workpiece?
The answer depends on the length of the piece. For short-length pieces, you can get by without a tailstock. However, a tailstock for long, slender pieces — such as a rifle barrel — a tailstock is vital to ensure accurate machining without distortion or chatter. Read more
How do you check tailstock alignment?
The center of the tailstock is aligned with the center of the spindle if it comes from the factory. If the tailstock is added to a rotary table, the center height of the tailstock is matched to the center height of the rotary table. If you want to check the alignment, you would use an indicator sweep of the tailstock quill. Indicators can be mounted to either the lathe spindle or the rotary table faceplate. Tailstocks can be adjusted side to side, but if the center height is off you will either need to add shims if it is low or remove material if it is high.
What are the different types of tailstocks?
There are manual, hydraulic, pneumatic tailstocks, and there are tailstocks with built in live centers. In the case of rotary tables, you can also get a heavy duty tailstock which looks more like a another rotary table to support heavy parts.
What types of centers are commonly used in tailstocks?
There are dead centers and live centers. Dead centers that do not turn are almost always used on manual machine tools or rotary table tailstocks. Live centers, with built in bearings, are commonly used on CNC machines and where higher RPMs are required.
