Classification and characteristics of cylindrical grinding machines. Cut in cylindrical grinder: When the length of the workpiece grinding part is less than the width of the grinding wheel, the grinding wheel only needs to make continuous lateral feed without relative axial movement with the workpiece. This type of grinder has high productivity. End face cylindrical grinder: The grinding wheel holder is tilted at an angle around the vertical axis, and the grinding wheel surface is polished into two grinding surfaces parallel and perpendicular to the workpiece axis. It can simultaneously grind the outer circle and shoulder end face of the workpiece, and is generally used for mass production. Universal cylindrical grinder: The grinding wheel holder is equipped with an internal cylindrical grinding accessory, and the grinding wheel holder and head holder can adjust an angle around the vertical axis. I...

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...
