CNC cylindrical grinder is a machine tool used for machining the outer surface of workpieces. It adopts CNC technology to achieve automated machining and has the characteristics of high precision, high efficiency, and good stability. The specific operating mechanism is as follows:
1. Workpiece clamping: The machine tool clamps and fixes the workpiece to be processed through fixtures or chucks to ensure the stability and accuracy of the workpiece during the machining process.
2. Spindle motion: The spindle of the machine tool is driven by a motor to achieve the rotational motion of the workpiece. The speed of the spindle can be adjusted according to the machining requirements.
3. Grinding wheel motion: The grinding wheel of the machine tool is driven by a motor to achieve rotational motion of the grinding wheel. The speed and feed rate of the grinding wheel can be adjusted according to the processing requirements.
4. Feed system: The CNC cylindrical grinder is equipped with a feed system to control the movement of the grinding wheel relative to the workpiece. The feed system can achieve different motion modes such as radial feed, tangential feed, and longitudinal feed according to processing requirements.
5. Control system: The core of the machine tool is the control system, which controls and operates the machining process through numerical control programming. The operator writes a numerical control program according to the processing requirements, inputs it into the control system, and the system controls the movement of the spindle, grinding wheel, and feed system according to the program instructions to complete the machining of the workpiece.
During the machining process, the machine tool controls the movement of the spindle and grinding wheel to generate cutting force from the relative motion between the grinding wheel and the workpiece, thereby achieving grinding of the outer surface of the workpiece. The control system accurately controls the processing requirements and parameters to ensure the stability and accuracy of the processing process.
In general, CNC cylindrical grinding machines achieve accurate grinding of the outer surface of workpieces, improve processing efficiency and product quality through the motion of the spindle and grinding wheel, control of the feed system, and application of CNC programming.
