The characteristics of CNC bearing grinder are as follows

CNC grinder manufacturers believe that the main faulty parts of CNC grinders are the CNC system and the machine tool itself. Due to the objective limitations of the CNC system, the working conditions of the bearing CNC grinder are quite harsh, and its CNC system is prone to software and hardware failures, making it difficult to find the fault point and therefore maintenance is very difficult. Because domestic CNC grinding machine manufacturers want to minimize costs as much as possible, the selected supporting components are also domestically produced. For example, the ball screw pairs and roller guides in the transmission part have poor quality and short service life. Due to the influence of materials and heat treatment, the transmission accuracy of CNC grinders generally decreases after one year of operation, resulting in poor positioning accuracy and repeated positioning accuracy of the machine tool.

CNC grinding machine manufacturers believe that the characteristics of CNC bearing grinding machines are as follows:

1. High precision. In order to ensure the accuracy of bearing grinding, CNC grinder manufacturers believe that in addition to the geometric accuracy and good structural characteristics of the machine tool body, it can also be achieved by reducing the errors of the CNC system and adopting certain compensation techniques. At the same time, it must have high-precision position measurement and a high-performance CNC system with a pulse equivalent of 0.1mm.

2. Fast processing speed and high efficiency. Improving productivity is also a major characteristic of CNC machine tools. Therefore, the frequency conversion spindle speed is generally 60000 r/min. When the machining diameter is less than 20mm, a spindle speed of 75000 r/min can also be selected. The CNC system automatically assigns feed rates and amounts for fast, rough, fine, and smooth grinding based on machining allowance, and automatically eliminates them.

3. High reliability is a key indicator of CNC machine tools. CNC grinding machine manufacturers believe that if evaluated using the mean time between failures, the mean time between failures should be above 40000 hours.

4. Intelligent adaptive control technology is adopted to detect the change signal of spindle current during bearing grinding process, automatically adjust the grinding parameters such as feed rate and feed rate of the CNC system, improve the grinding state, and achieve good grinding effect. At the same time, the CNC system should have self diagnostic function, which can timely detect and eliminate fault components.
