Gantry surface grinder P2060
1.High rigidity/regrinding:
Surface/contour/surface forming grinding
2.Machine tool characteristics:
High rigidity structure
The fuselage is designed as an integrated double V track structure. All the castings are made of high-grade cast iron, which is annealed and aged to eliminate the internal stress. The box body is equipped with reinforced ribs to enhance the structural rigidity.
Lubrication system
The high precision lubrication system makes the machine run more stable and can withstand regrinding. The precision feed system greatly improves the grinding efficiency.
Worktable
Table moving back and forth (X axis) slide rail, using double V structure design, continuous forced lubrication, avoid wear, high motion accuracy, high service life.
Ball screw
The machine adopts C3 precision ball screw, which is directly driven by servomotor.
3.Precision spindle:
The main shaft of the grinding wheel is made of nickel-chromium alloy steel, and the internal stress is eliminated through heat treatment, precision grinding and dynamic balance correction.
The grinding wheel mandrel adopts dynamic pressure composite lubrication design, which is easy to form a higher oil film supporting pressure. When it is lower than the working pressure, the automatic pressure detection switch will prevent the start of the abrasive wheel shaft to avoid the mutual wear between the mandrel and the copper bearing shaft. Moreover, the lubricating oil temperature control cooling device is attached to avoid the oil viscosity decreasing due to high temperature, thus affecting the maintenance of pressure.
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. Machine guide rails and precision ball screws are continuously lubricated by automatic lubrication system to ensure longer service life and accuracy. The cooling system is separated from the body to eliminate vibration and favorable heat dissipation.
3.Equipped with Siemens 828D CNC automatic grinding system, and secondary development, man-machine dialogue fool operation, with many optional equipment to choose from, including inner hole grinding device, automatic end measuring device, automatic outside diameter measuring device, etc.
4. 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.
5. 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.
6. 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.
7.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.
