Equipment Introductions
The CNC internal grinder machine's main structural features are as follows:
- It features a fully enclosed protective cover, a two-axis CNC model, and is controlled by a Siemens CNC system.
- The CNC internal grinder machine bed is constructed of a casting, and the base has undergone multiple treatments, ensuring excellent rigidity and resistance to deformation. The guide rails utilize a plastic-coated design to reduce machine vibration, extend service life, and improve feed sensitivity.
- The feed screw is a high-precision ball screw. The workpiece spindle utilizes AC frequency conversion for stepless speed change. The spindle is fixed to the worktable, which reciprocates, while the grinding wheel carriage is fixed to the bed bridge, providing feed motion for the grinding wheel. - The spindle box utilizes a high-precision sleeve spindle, with both front and rear bearings featuring high-precision bearings for high rotational accuracy. The working spindle motor is an AC variable-frequency motor with stepless speed regulation.
- The grinding head spindle utilizes a highly rigid, high-precision mechanical spindle, with a standard 24,000 rpm high-speed mechanical spindle. Custom abrasives can be customized to meet grinding requirements for a wider range of sizes.




- The CNC internal grinder machine tool fixture utilizes a three-jaw chuck, with an optional hydraulic chuck for automatic loading. The worktable utilizes a flat-V hydrostatic oil-film guideway, a one-piece wear-resistant casting. The grinding wheel has a 105mm feed stroke and is equipped with an independent cooling water tank.
