What is workpiece clamping?

First, in the process of machining, in order to ensure the machining accuracy, before machining, the position of the workpiece on the machine tool should be determined and fixed for machining or testing. The process of locating and clamping a workpiece on a machine tool or fixture is called clamping.

2. The installation of the workpiece includes two aspects:

1. positioning: the process of determining the correct position of the workpiece on the machine tool or fixture is called positioning;

2. Clamping: The operation of fixing the workpiece after positioning to keep the positioning position unchanged during machining is called clamping.

Machine tool fixture: proces equipment that can locate, clamp and guide that tool conveniently on the machine tool, called fixture. Using fixture to position and clamp the workpiece has the characteristics of fast and convenient operation, high positioning accuracy, stability and high productivity.

Fourthly, the fixture has been adjusted on the machine tool in advance, and the workpiece can be positioned by the positioning device provided by the fixture, so as to establish the correct position on the machine tool. The correct position of the machined surface of the workpiece relative to the tool can also be ensured by the tool alignment device on the fixture. In the case of using fixture, the mutual position accuracy of workpiece, machine tool and tool is guaranteed by fixture.
