With the development of manufacturing industry, the application of numerical control machine tools is becoming more and more extensive in the modern machine manufacturing. Design of machine tool fixture, can greatly improve the production efficiency of machine tools. Xiamen machine tool fixture design in the design should pay attention to the following points:

1 NC machine tool fixture without cutting tool guide device. This is because the numerical control machine tool processing, the machine tool, the jig, the tool and the work piece always maintains the strict coordinate relations, the tool and the work piece need not need the guide element to determine the position. .

2 numerical control machine tool fixture clamping should be firm and reliable, easy to operate. The clamping element position should be fixed, to prevent the automatic process, components and tools together.

3 CNC machine tools should be used as far as possible to choose the adjustable fixture, fixture and modular fixture. Because machining CNC machine tools, is often a single and small batch production, must adopt flexible fixture, short preparation time.

4 CNC machine tools often need to work in several directions on the workpiece machining, so the numerical control machine tool fixture should be open.
