1. The transmission chain is short. Compared with ordinary machine tools, the spindle drive is no longer a motor-belt-gear pair mechanism. Instead, it uses horizontal and vertical feed to be driven by two servo motors. Traditional components such as clutches and clutches have greatly shortened the transmission chain. Kan

2. High rigidity. In order to match the high precision of the numerical control system, the rigidity of the numerical control machine tool is high to adapt to the high-precision processing requirements.

3. Light drag, the tool holder (worktable) moves with ball screw pair, which has low friction and light movement. Screw at both ends of the support-type special bearings, the pressure angle is larger than ordinary bearings, in the factory will be selected good; CNC machine tool lubrication part of the use of oil mist automatic lubrication, these measures make the CNC machine tool mobile light.

CNC machine tool processing characteristics

A high degree of automation can reduce the manual labor intensity of the operator. The CNC machining process is automatically completed according to the input program. The operator only needs to start the tool, load and unload the workpiece, and replace the tool. During the machining process, the main task is to observe and supervise the operation of the machine tool. However, due to the high technical content of CNC machine tools, the operator's mental work increased accordingly.

2. The machining parts have high precision and stable quality. The positioning accuracy and repeated positioning accuracy of CNC machine tools are very high, and it is easier to ensure the consistency of the size of a batch of parts. As long as the process design and procedures are correct and reasonable, coupled with careful operation, the parts can be guaranteed to obtain high machining accuracy, and it is also convenient to implement quality control in the machining process. Kan

3. High production efficiency. Numerical control machine tool processing can process multiple processing surfaces in clamping again, and only the first piece is generally detected. Therefore, many intermediate processes, such as marking and size detection, can be used in ordinary machine tool processing in provinces and regions, thus reducing auxiliary time. Moreover, due to stable quality of parts processed by numerical control, convenience is brought to subsequent processes, and its comprehensive efficiency is obviously improved. Kan

4, to facilitate the development and modification of new products. CNC machining generally does not require a lot of complex process equipment, through the preparation of processing procedures can be complex shapes and high precision parts processing out, when the product modification, change the design, as long as the change program, without the need to redesign the tooling. Therefore, CNC machining can greatly shorten the product development cycle, for the development of new products, product improvement, modification provides a shortcut. Kan

5, can be developed to a more advanced manufacturing system. CNC machine tools and their processing technology is the basis of computer-aided manufacturing. Kan

6, the initial investment is large. This is due to the high cost of CNC machine tool equipment, the first processing preparation cycle is long, and the maintenance cost is high. Kan

7, high maintenance requirements. CNC machine tools are technology-intensive mechanical and electrical integration of typical products, the need for maintenance personnel to understand both mechanical, but also understand the knowledge of microelectronics maintenance, but also equipped with better maintenance equipment.
