What Is Distance Between Centers On A Lathe: A Comprehensive Guide

The term “distance between centers” in the context of a lathe refers to the maximum length of a workpiece that can be securely clamped between a center positioned in the headstock and another center located in the tailstock of the lathe. In essence, it represents the lathe’s capacity to accommodate longer workpieces. This measurement is an important specification used to describe the size and capabilities of a lathe, with the first number usually denoting the swing over the bed, and the “distance between centers” being the second number. Together, these specifications provide a comprehensive understanding of the lathe’s size and suitability for various machining tasks.

What is turning between centers? Turning between centers is a fundamental machining technique used when a workpiece needs to be precisely machined using specialized centers. In this process, a center, typically a lathe center, is carefully inserted into a corresponding hole that has been created using a center drill. This hole starts as a conical shape near the surface of the workpiece and gradually becomes cylindrical as it extends deeper. Turning between centers is a critical method in machining that ensures accurate and centered rotation of the workpiece during various machining operations, contributing to the production of high-quality and precise components.
