2.Device description:
1)  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) the domestic initiative of the core type grinding machine structure, so that the grinding wheel processing from the outer surface of the small grinding, low efficiency. With the end face as the initial surface of rough machining, processing quantity is large, processing efficiency is high, at the same time for small diameter segment difference workpiece more advantages.

3)   Adopt the Chinese secondary development highly automatic grinding system jointly developed by Hotman, which can freely move and rearrange buttons and ICONS, and realize the creation interface of multi-step complex work piece with different sections without programming. The interactive touch screen technology with excellent performance can easily realize more advanced gesture instructions.
4) Operators can according to the definition of a variety of shapes, according to the shape of the workpiece, quickly arrange the combination of graphics and input related parameters, you can complete programming processing graphics.
5)     Precision linear 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 and lubrication systems are separated from the body to eliminate vibration and facilitate heat dissipation.
6)  High precision motorized spindle is selected as the main shaft of grinding wheel. The spindle keeps a constant temperature through internal oil cooling and is equipped with adjustable speed regulating device. The maximum linear speed of grinding wheel can reach 90m/S.
7)   The machine itself is equipped with the standard clamping method for the collet type, using the Swiss Choplin clamping assembly, clamping precision is high, good durability.
8)  Automatic loading and unloading manipulator is the power supply of 3 ANCA servomotor. Through the combination of precision rail and ANCA control system, in the process of feeding and receiving, the whole process of feeding and receiving can be completed efficiently, accurately and conveniently.
9)   Using Italian Marposs contact or Japan Keenes laser positioning device, using the way of front positioning, can accurately process the multi-stage segment difference of the workpiece, ensure the length of the workpiece segment difference, and eliminate the influence of the error caused by the automatic feeding device and installation.
