Internal Grinder For Small Inner Diameter Minimum 6 mm, Applicable for Various Size Workpiece
Machine tool accuracy:

Machine tool accuracy test list (included)

After grinding (grinding) by Hotman's differential grinding machine, the following requirements shall be met: (Different grinding wheels shall be used for different materials)

Note: rough grinding (generally grinding amount 0.02~0.05mm); Fine grinding (generally grinding amount 0.005~0.015mm)

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.

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.

Grinding wheel spindle adopts FAG high-precision spindle bearing sleeve structure, without separate lubrication, simple maintenance, free of metal-to-metal contact, grinding wheel spindle has the characteristics of high rigidity and precision, can obtain nearly permanent service life. For special workpiece grinding, optional motorized spindle, with the function of increasing linear speed.

Equipped with Siemens 828D CNC automatic grinding system, and secondary development, man-machine dialogue fool operation, with many optional equipment to choose.

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.

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.

Siemens numerical control systemas the standard configuration, after secondarydevelopment, all Chinese operation interface, easy to use. Equippedwith Siemens high performance servomotor, the equipmentCNCsystemanddrivesystemhavebettercompatibility,at the same time with automatics and repair and automatic compensation function,to ensure the stability and precision of feed and grinding.

• Grinding program is created automatically through the user-friendly interface, using graphical programming tools shopmill / shopturn, unnecessarily needing special G codes (Optional).
• No need battery or cooling fan. And no need memory battery for the motor coder.
• Ethernet connector. No capacity limit USB (on line) and CF card. The programs in USB and CF card can be modified at will. Process monitor on line. And the data can be saved forever.
• Process showing with animation. High efficiency.
• There are kinds of optional functions, including automatic end-surface measuring, automatic inner diameter measuring, hydraulic tail stock, highly integrated auto loading and unloading system, and so on.
• Automatic wheel dressing and offset. Keep high precision and stability for the feeding and grinding.
