Cylinderical grinding machine+internal hole grinding device:
Device description:
The body and components are cast by Milhanna high grade cast iron FC30. 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.
The grinding wheel spindle adopts FAG high-precision bearings, the first four and the second two sleeve structure, without separate lubrication, simple maintenance, free of metal-to-metal contact, and can obtain nearly permanent service life. The grinding wheel spindle has the characteristics of high rigidity and high precision. For special workpiece grinding, the grinding wheel speed can be adjusted to increase the linear speed
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.
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.
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.
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.
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.
Special thread for lead screw/tap Grinding process of shovel grinding
The spindle is equipped with high resolution encoder as position feedback, full closed-loop control.Simple assembly, short transmission chain, compact structure, good accuracy and stability.
Equipped with CNC grinding wheel dresser, interpolated by two CNC axes W and V,High precision dressing of grinding wheel is carried out by diamond disc wheel driven by servo motor.
Linear movement of workpiece is driven by linear motor and equipped with high resolution grating ruler.Ensure high precision machining.
