High Precisioin CNC Internal Grinding Machine for Large Size, Excess Grinding Volume Workpieces
Device description:
1. The body and components are cast by Milhanna high grade cast iron FC30, which is artificially normalized heat treatment and then treated by natural aging. Components are processed by YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment once clamping processing. Precision size can be up to micron level, to ensure high precision equipment basic components.
2. An automatic centralized lubrication system lubricates the machine linear guides and ball screws continuously, which makes sure longer service life and high precision. The cooling system is separated with machine body, which eliminates vibration and helps heat radiation.
3. The grinding wheel spindle adopts an electric spindle with the characteristics of high speed, high precision, high rigidity, low vibration, low noise and low temperature rise. The driving system is cooled by a water cooling system to ensure that the grinding wheel headstock always works in a thermally stable state, making the grinding wheel more stable, and working efficiency is doubled. According to the processing needs, electric spindles with different speeds of 24000-60000rpm are optional; for workpieces with deep inner circles, an integrated spindle can be customized to achieve precision grinding.
4.It adopts German Siemens CNC system and has undergone further development. It has a user-friendly human-machine dialogue operation interface and is equipped with Siemens high-performance servo motors, which makes the equipment CNC system and transmission system have better compatibility. It also has automatic sand dressing and automatic offset function, which ensures the stability and accuracy of feed and grinding.
5. The grinding feed system is composed of a V and a flat track of hand-crafted precision shovel, with automatic lubrication system and C3 level precision grinding ball screw, which can achieve smooth movement, excellent repeated positioning accuracy and long track life.
6. The standard configuration of the grinding wheel spindle is rear four and rear two bearing structure. High precision dynamic and static pressure spindle can also be selected, which has the characteristics of high rotation precision, high dynamic stiffness, good vibration resistance, high grinding efficiency and good grinding surface quality. For special work-piece grinding, the grinding wheel speed can be adjusted, up to 3500 RPM and 60m/s.
7. The tail seat is designed to be both rigid and robust. A hardened alloy steel sliding cylinder encrusted in the cast iron body is designed to carry the MT4 top core. The jacking force of the sliding cylinder can be easily changed by adjustment knobs at the rear. Special accessories oil pressure tail seat with a pedal to facilitate unloading work parts.
8.Siemens numerical control system as the standard configuration, after secondary development, all Chinese operation interface, easy to use. Equipped with Siemens high performance servo motor, the equipment CNC system and drive system have better compatibility, at the same time with automatic sand repair and automatic compensation function, to ensure the stability and precision of feed and grinding.
