In the CNC machining process, the fixtures are the process devices used to quickly fasten the workpiece during machining, so that the machine, the tool, and the workpiece can maintain the correct relative position. Fixtures are indispensable parts in CNC machining. Driven by the development of machine tool technology in the direction of high-speed, high-efficiency, precision, composite, intelligence, and environmental protection, fixture technology is developing in the direction of high-precision, high-efficiency, modular, combined, universal, and economical. In a broad sense, any process in the processing process, a device used to quickly, conveniently and safely install a workpiece can be called a fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures for short.
What are the types of fixtures we use for CNC machining? Below is a detailed classification of fixtures by 3QMACHINING.
- General CNC machining fixture
General CNC machining fixtures refer to fixtures that have been standardized and can be used to process different workpieces within a certain range. For example, three-jaw chucks and four-jaw chucks, top and core chucks on lathes; flat-nose pliers, indexing heads, and rotary tables on milling machines. They have great versatility and can be used to clamp different workpieces without adjustment or slight adjustment. This type of fixture has generally been standardized. Produced by a professional factory and supplied to users as machine tool accessories.
