● The axial direction of the lower disc adopts the bearing structure of hydrostatic rotary table, which has the characteristics of high precision and high rigidity, and has good accuracy retention for high-pressure loading grinding processing.
● The inner and outer ring gear of the upper and lower discs adopts four-motor independent drive, and the process adjustment range is wide, and the process parameters can be flexibly adjusted according to different material products.
● The upper plate adopts a floating cylinder mechanism to adjust the balance, and the four groups of floating cylinders are arranged symmetrically and evenly to improve the processing efficiency on the premise of maintaining processing accuracy.
●The upper and lower plates have independent cooling channels to cool the grinding disc, and the upper and lower discs are equipped with multi-point temperature sensors (with wireless sensing), which control and adjust the refrigeration capacity through real-time temperature monitoring to ensure that the temperature of the grinding disc is uniform and constant.
● Equipped with online inspection system (optional), to achieve simultaneous processing and testing, high processing qualification rate.
