Universal Grinder UG-500
* The worktable and wheelhead guideway adopt hydrostatic lubrication, its movement on low speed is smooth.
* Wheel head spindle is supported by hydrostatic and hydrodynamic bearings of high rigidity, it makes the spindle have high rotary accuracy and perfect rigidity.
* For UG-500, spindle of workhead adopts sliding bearing structure. the clearance of the front bearing can be adiusted to make it suitable for the grinding use center or chuck.
