-lomflMo TOPKING TECHNOLOGY CO., LTD. HYDROSTATIC CENTERLESS GRINDER NC series The H Series is built around static pressure technology, offering high precision, low wear, and long-term stability to ensure consistent processing quality. The wheel spindle, regulating wheel spindle, and feeding axis (lower slide rail) are supported by a static pressure oil film, allowing for contact-free operation. This prevents mechanical wear and maintains high precision even during extended use. Its high rigidity and damping characteristics effectively reduce vibration, enhancing stability and surface quality during machining. The minimum feed rate is as low as 0.0005mm, ensuring excellent roundness, surface quality, and dimensional accuracy of the workpiece. HYDROSTATIC SPINDLE AND SLIDE RAIL■ No abrasion between metal to metal, improving the service life of the machine. ■ Extremely low metal friction. Low-temperature rise during processing, not easy to deform, improves processing stability and component accuracy. ■ High-pressure oil film wraps around the spindle, suitable for high-speed rotation. ■ High-precision application and constant rotation ensure rotation accuracy. ACCUMULATOR FOR PROTECTION DEVICE The special pressure accumulator design can make the hydrostatic oil return to the hydrostatic system of the main shaft when the pressure drops due to power failure. It can avoid the damage caused by the momentary loss of static pressure oil film caused by power failure when the spindle is running at high speed. HYDROSTATIC GUIDEWAY CONSTRUCTION ■ R.W. lower slider (infeed axis) is a hydrostatic guideway construction design. This provides various features such as extremely smooth and fast sliding movement, high precision feeding accuracy, and stable grinding accuracy. ■ he lower feeding axis is driven by a servo motor cooperating with a harmonic reducer. The advantages are reducing backlash, increasing torque, improving grinding efficiency, and stabilizing precision grinding quality. OIL COOLANT SYSTEM The oil coolant system is equipped with an oil cooler to effectively maintain a constant oil temperature and prevent the spindle from affecting the machining accuracy due to changes in oil temperature.
