CNC machine tool accessories mainly include the following:

1. Cutting tools: used for cutting, turning, milling, drilling and other processing techniques. Common cutting tools include turning tools, milling cutters and drill bits.

2. Fixture: It is used to fix and clamp the workpiece to maintain the stability of the workpiece during processing. Common fixtures include fixture tables, fixture plates and fixture racks.

3. Bearings: used to support rotating parts, reduce friction and wear, and improve the accuracy and stability of machine tool operation.

4. Servo motor: controls the movement of each axis to achieve precise position control, and is commonly used in the feed system of CNC machine tools.

5. Sensor: used to monitor and measure the operating status of the machine tool and the processing status of the workpiece. Common sensors include position sensors, speed sensors, and force sensors.

6. Control system: used to program, control and monitor the operation of CNC machine tools. Common control systems include CNC systems and PLC (programmable logic controller).

The main purpose of CNC machine tool accessories is to improve the machining accuracy, stability and efficiency of the machine tools. They play a key role in positioning, fixing, cutting and rotating in each process, so that the machine tools can realize automated processing according to the predetermined program.
