1. The worktable and wheelhead guideway adopt hydrostatic lubrication, ensuring smooth movement even at low speeds.
2. The wheel head spindle is supported by hydrostatic and hydrodynamic bearings of high rigidity, providing high rotary accuracy.
3. For UG-500 models, the workhead spindle adopts a sliding bearing structure with adjustable clearance, ideal for center or chuck grinding.
