CNC machining fixture requirements

Fixture is an essential part of CNC machining center. Each CNC machining center will use fixture. According to the different products processed, the fixture used is different, and the requirements for fixture are different. However, CNC machining center has similar requirements for fixture, and special workpiece has different requirements for fixture. So what are the requirements of CNC machining center for fixture? Let’s have a brief understanding:

1. High precision fixture

As we all know, CNC machining center has a very high precision, which is usually used to process parts or molds with high precision. For this reason, CNC machining center also puts forward the requirements of fixture high-precision positioning and installation, as well as the requirements of transposition and positioning accuracy.

1. The fixture should be convenient and fast when clamping the workpiece

In order to meet the high-speed machining fixture of CNC machining center, hydraulic and pneumatic fast locking power is adopted, especially for the workpiece locking with long processing time. The general hydraulic clamping system will be attached with a storage device, which can supplement the internal leakage and prevent the workpiece from loosening on the fixture.

1. The fixture should be open

CNC machining center is processed by the tool contacting the workpiece. Under the clamping of the workpiece, the workpiece should provide relatively spacious operation space for the fast moving tool and tool changing quick action. Especially for the complex workpiece with multiple tool changes, the fixture structure should be as simple, convenient, fast and open as possible to make the tool easy to enter and exit, and prevent the tool from colliding with the fixture workpiece in the process of processing.

1. The fixture should have high adaptability

We all know that CNC machining center is flexible and multi deformation, so the fixture should have high efficiency adaptability to different workpiece and different clamping.

The above is the CNC machining center on the clamp requirements, I hope to help you.
