Product Description
(1)
Body
The body and components are cast with high-grade cast iron FC-30, which is artificially normalized heat treatment and then subjected to natural aging treatment. Component processing adopts YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment for one-time clamping processing, precision size up to micron level, to ensure the high precision of the basic components of the equipment.
(2)
Automatic lubrication system
Machine guide rail and precision ball screw are continuously lubricated by automatic lubrication system to ensure longer service life and maintain the best accuracy for a long time. The cooling system is separated from the body to eliminate vibration and facilitate heat dissipation.
(3)
Automatic system
The first compound grinder in China with one clamping, realizing the integrated grinding of inner circle, inner cone, outer circle, outer cone and end face. The standard configuration is Siemens NC system, and there are many optional accessories to choose from, including automatic rotating device of working head, automatic outer diameter measuring device, automatic end face measuring device, magnet paper tape filter device, oil mist collector, etc.
(4)
Working head manual adjustment device
For the grinding of outer cone and inner cone work piece, the working Angle can be adjusted manually.
(5)
High precision feed system
The grinding feed system is composed of Japanese THK linear guide rail with automatic lubrication system, precision THK ball screw, and silent motor, which can achieve smooth movement, excellent accuracy and repeatability, and long track life.
(6)
Grinding wheel spindle
The outer spindle of grinding wheel adopts FA-G high-precision spindle bearing structure, sleeve structure, no separate lubrication, simple maintenance, eliminating metal-to-metal contact, and 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. High speed motorized spindle is selected for inner circular spindle to prevent the influence of resonance of inner and outer circular motor.
Working head stroke of internal grinding wheel: 0-500mm
Working head stroke of cylindrical grinding wheel: 0-400mm
(7) CNC system
German Siemens CNC system, and after secondary development, idiot Chinese man-machine dialogue operation interface, with Siemens high performance servo motor, so that the equipment CNC system and transmission system has better compatibility, at the same time with automatic sand repair and automatic compensation function, to ensure the stability and precision of feed and grinding.
