The fixture is one of the indispensable accessories when using the best budget cnc mill for parts processing. The choice of the type of fixture is generally determined according to the type of parts processed by the CNC machining center, and the fixtures used are different for different types of processed products. However, CNC machining centers have the same requirements for fixtures, unless there are parts with special processing requirements, special custom fixtures are required. So what are the requirements of the CNC machining center for clamping when processing parts? As a professional machining center manufacturer, we will introduce in detail for reference:
CNC machining center requirements for fixtures:
High-precision fixture
As we all know, the machining accuracy of CNC machining centers is very high. Users who choose to use CNC machining centers are generally used for parts or molds with higher machining accuracy requirements. Therefore, in this case, the accuracy requirements of the fixture are also relatively high, and its accuracy The requirements generally include the installation of high-precision positioning of the fixture and the requirements for indexing and positioning accuracy.
The fixture should be convenient, fast and efficient when clamping the workpiece;
The running speed of CNC machining centers is relatively high. Under this high-speed machining state, machining requires higher clamping of fixtures. Common fixture locking generally includes hydraulic and pneumatic locking. The workpiece with a long processing time will generally choose hydraulic clamping. The system will be equipped with a storage device to supplement internal leakage and prevent the workpiece from loosening during processing on the fixture.
The fixture should have good openness;
CNC machining center processing is a process in which the tool contacts and feeds the workpiece. When the workpiece is clamped in the fixture, the rapid movement of the machining center machine tool and the rapid tool change action of the tool magazine are the same. Therefore, the selected fixture must have a comparison Spacious operating space. Especially for workpieces that are complex to process and require 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 avoid collisions between the tool the fixture workpiece during the processing movement.
The adaptability of the fixture should be strong;
CNC machining centers have flexibility and variability during processing, so the fixtures are required to have high adaptability when responding to different workpieces and different clamping requirements.
