CNC machine tools are high-precision, high-efficiency mechanical processing equipment equipped with various accessories to meet different processing needs. These accessories can help machine tools complete the processing tasks of workpieces of different shapes and materials. Accessories for CNC machine tools usually include the following:

1. Tools and their tool holders: The tools of CNC machine tools are mainly divided into rotatable tools and non-rotatable tools. The rotatable tools are generally composed of a tool holder and a blade nested. Different toolholder and insert combinations can meet various machining needs, such as turning, milling, drilling and more.

2. Fixture: The fixture is a very important auxiliary equipment on CNC machine tools. It can ensure the stable clamping of the workpiece on the machine tool and ensure the processing quality. Clamps come in different shapes and mounting methods, such as chucks, machine tool slot plates, etc.

3. Tool grinder: Tools on CNC machine tools require regular maintenance and grinding. A tool grinder is a piece of equipment specially used for tool grinders. It can help machine tool cutting tools stay sharp and ensure processing quality.

4. Automatic tool changer: The automatic tool changer is a very practical accessory for CNC machine tools. It can realize automatic tool change according to different tools during processing. This can greatly improve processing efficiency and reduce the work intensity of operators.

5. Measuring instruments: In order to ensure the processing accuracy of CNC machine tools, it is usually necessary to use various measuring instruments to monitor and measure the processing process. These instruments mainly include micrometers, altimeters, vibration testers, etc.

In short, CNC machine tool accessories are an important part of CNC machine tools, which can greatly improve the operating efficiency and processing quality of the machine tool. Appropriate use of accessories can help the machine tool complete more different types of processing tasks and meet different processing needs.
