What requirements does the CNC machining center have for the fixture?

The fixture is an integral part of the CNC machining center. If you want to produce an Aluminum Machining part, etc., depending on the processed product, the requirements for the fixture will be different, and you need to use the corresponding fixture. In general, the fixtures of CNC machining centers need to have the following attributes.

1. High precision

We know that the precision of CNC machining centers is very high, such as SteelMachining and other parts, which are generally used to process high-precision parts or molds. Therefore, CNC machining centers have relatively high requirements for positioning accuracy.

2. Convenient and fast

In order to meet the requirements of high-speed processing of machining centers, convenient and fast fixtures are often required, so high-speed locking power, such as hydraulic or pneumatic, is often used. If it is a workpiece with a long processing time, hydraulic clamps are generally used, and internal leakage is compensated during processing to prevent the clamp from loosening.

3. Good opening

The CNC machining center is processed by the contact feed between the tool and the workpiece. In order to realize the rapid movement of the workpiece and the quick operation of tool change, the workpiece should be clamped by the fixture to provide a relatively spacious operating space. Especially for those complex workpieces that involve multiple tool changes, the structure of the fixture should be simple, convenient, and fast, and open as much as possible so that the tool can easily enter and exit, and the fixture will not be affected during the machining operation. Collision with workpiece.

4. High adaptability

The workpieces processed by CNC Machining are often diverse, so the fixture needs to adapt to workpieces of various shapes.
