How to adjust CNC cylindrical grinder

2025-04-10

How to adjust the CNC cylindrical grinder?1、 The use and adjustment of grinder head frame.1. The head frame dial is generally achieved through segmented stepless speed regulation through pulleys and frequency converters.2. The gap between the headstock spindle and the bearing is mainly adjusted by rotating the scale sleeve. If it rotates clockwise, the gap increases, and vice versa. However, the gap should not be less than 0.005mm.3. Before rotating the scale sleeve, the idle amount on top should be removed to ensure accuracy.2、 The use and adjustment of grinder tailstock.1. If you want to retract the tailstock socket, you usually need to turn the wrench.2. The automatic advance and retreat of the tailstock sleeve is mainly achieved through foot pedals.3. To adjust the force of the pointed workpiece, it is usually done by rotating and adjusting the gripper. ...

Four clamping methods for grinding on a surface grinder

2025-04-10

Four clamping methods for grinding on a surface grinder.Common thin sheet parts such as gaskets, friction plates, templates, and thin plates are prone to clamping deformation during clamping and warping during grinding due to poor rigidity, difficult heat dissipation, and bending after heat treatment. Magnetic suction cups are usually used for grinding on surface grinders. After grinding is completed, the magnetic attraction is removed, and the thin sheet workpiece is restored to its original state, making it difficult to ensure machining accuracy. If the following clamping methods are used to ensure the positioning and clamping of thin sheet workpieces in a free state, and double end faces are used for grinding processing, good results can be achieved to meet the requirements of part processing accuracy.1. Elastic gasket clamping method.2. Strengthen the rigidity of thin sheet workpieces with temporary mea...

Regarding the manufacturing method of the tailstock for external cylindrical grinding machines

2025-04-09

Regarding the manufacturing method of the tailstock for external cylindrical grinding machines.The workpiece spindle device and tailstock of the external cylindrical grinder are installed on both ends of the worktable. The tailstock is matched with the worktable through a sliding groove tenon structure. One end of the workpiece with a longer axial length is clamped by the workpiece spindle device, and the other end is supported by pushing the tailstock to drive the pointed shaft on the tailstock. Then, manual control is used to generate a pressing force on the workpiece. The workpiece spindle device drives the workpiece to rotate, and the grinding wheel device performs external surface machining on the workpiece.During the process of pushing the tailstock to the top, if the pointed axis on the tailstock moves quickly, it is easy to generate a large impact force on the workpiece, affecting the machining accu...
