High Precision CNC Centerless Grinding MachineFX-20CNC-3


1.Super grinding force
2.The sand wheel shaft is the hydrostatic main shaft
3.Large diameter workpiece grinding is preferred
●Low center of gravity design, increase the grinding stability,can ensure the accuracy of machine tools for a long time.
●Super grinding force, more suitable for large diameter workpiece processing, greatly shorten the processing time.
●It is very suitable to install automatic equipment such as manipulator lifting grinding/automatic feeding and receiving.

Grinding wheel dressing part:

●Sand repair system adopts two-axis linkage, with servo motor and ball screw drive, the grinding wheel forming precision is high, the dressing speed is fast.

●Roller dressing can be quickly interchangeable with single point sanding pen to realize different types of grinding wheel dressing

●Grinding tungsten steel long rod using roller dressing and mutual repair, sand repair efficiency is fast, the grinding wheel cutting surface is flat, can make the grinding wheel contact surface larger and more uniform.

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.

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.

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 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.
