machine tool

Machine rigidity determines the machining accuracy of hard turning. Almost all the machine tools manufactured in the past 15 to 20 years are very rigid enough to withstand hard turning. In many cases, the overall condition of the machine tool is more important than its useful life, and well-maintained ordinary lathes can also be used for hard turning.

In order to add rigidity and damping characteristics to hard turning machine tools, Hardinge has used many advanced machine tool features for turning centers, including polymer composite reinforced machine bases, direct-fitting types with spring collets (to bring the spindle support close to the workpiece) Spindle and hydrostatic guide.

Maximizing system rigidity means minimizing overhangs, tool extensions, and part extensions, and eliminating spacers and washers. The goal is to keep all components as close to the turret tool post as possible.
