Chuck turning and milling composite machining technology is a highly integrated precision machining method that combines the advantages of turning and milling. Through highly automated CNC equipment, it realizes efficient and high-precision machining of materials. In the manufacturing process of the chuck, turning is mainly used to initially remove excess material and form the basic outline of the chuck; while milling focuses on fine machining of the details of the chuck to achieve the final dimensional accuracy and surface quality requirements.

Copper, with its good physical and chemical properties, has become one of the ideal materials for chuck manufacturing. First of all, copper has good strength and toughness, can withstand various mechanical stresses during the machining process, and ensure the stability and reliability of the chuck in long-term use. Secondly, copper has excellent wear resistance, can effectively resist the friction and wear generated by the tool during the machining process, and extend the service life of the chuck. In addition, copper also has good electrical conductivity and thermal conductivity, which helps the machine tool and tool to operate stably and dissipate heat during the machining process.

Entering the milling stage, the machining of the chuck has entered the most critical link. The task of this stage is to use high-precision milling tools and fixtures to finely process the details of the chuck to meet the final dimensional accuracy and surface quality requirements.

The selection of milling tools is directly related to processing efficiency and processing quality. When selecting milling tools, multiple factors such as the material, shape, size and processing requirements of the chuck need to be considered. For the processing of copper chucks, carbide or ceramic milling tools are usually used. These tools have high hardness and wear resistance, and can effectively resist the adhesion and wear of copper during processing.

The fixture is an indispensable auxiliary tool in milling processing. It is responsible for fixing the chuck on the machine tool to ensure stability and accuracy during processing. In the chuck turning and milling composite processing, the design of the fixture needs to fully consider the shape, size and processing requirements of the chuck. Customized fixtures are usually used to ensure that the chuck can be firmly fixed on the machine tool during processing to avoid shaking and displacement during processing.

The control of the milling process is the key to ensuring processing quality. During the milling process, the cutting parameters, including cutting speed, feed rate, cutting depth, etc., need to be strictly controlled to ensure the stability and accuracy of the processing process. At the same time, it is also necessary to monitor the wear of the milling tool in real time, replace the severely worn tool in time, and avoid the occurrence of processing errors.

In the milling stage, the details of the chuck need to be finely processed, including milling planes, slots, threads and other complex shapes. The processing requirements of these details are extremely high and need to meet the micron-level precision requirements. Through the turning and milling composite processing technology, the micron-level processing of copper materials can be achieved to ensure that every detail of the chuck meets the design requirements.
Milling plane: The plane is one of the most common shapes in the chuck. When milling the plane, it is necessary to ensure the flatness, verticality and parallelism of the plane. Through high-precision milling tools and fixtures, as well as precise cutting parameter control, the micron-level processing accuracy of the plane can be achieved.
Slot processing: The slot is an important part of the chuck for installing tools or connecting other parts. When milling the slot, it is necessary to ensure the dimensional accuracy, shape accuracy and position accuracy of the slot. Through precise tool path planning and cutting parameter control, the micron-level processing accuracy of the slot can be achieved.
Thread processing: The thread is a key part of the chuck for connection and fixation. When milling threads, it is necessary to ensure the thread pitch, tooth angle, thread depth and other requirements. Through high-precision thread milling tools and precise cutting parameter control, micron-level thread processing accuracy can be achieved.

Inspection and evaluation of processing quality
After the chuck milling composite processing is completed, the processing quality needs to be strictly inspected and evaluated. This includes measuring and inspecting the chuck's dimensional accuracy, shape accuracy, position accuracy, and surface quality. Through high-precision measuring equipment and professional inspectors, it can be ensured that the chuck's processing quality meets the design requirements.
