Description

Turning fixing tool clamp

Technical Field

The utility model relates to the technical field of turning, in particular to a turning fixing tool clamp.

Background

Turning is a machining method for cutting a metal material with a cutting tool on a rotating machine. In metal forming processes, turning is mainly used to remove excess material, thereby producing parts of complex shape and precise dimensions. Turning is widely used in a variety of applications including automotive, mechanical, tool, electronic equipment, etc.

In order to ensure stability during machining, the workpiece needs to be fixed on a workbench of a machine tool during turning. This prevents the workpiece from moving or tilting under the cutting force, thereby maintaining the machining accuracy. If the fixing effect is not good, movement or tilting may occur during the machining process, resulting in a decrease in machining accuracy, and excessive material may be cut off by the cutting tool during the cutting process, resulting in waste. Therefore, we propose a turning fixing tool clamp.
