UG-320H UG-320BF
Main Functions and Features
1. UG-320H and UG-320BF universl cylindrical grinder is an improved design of its predecessor, G-320 and UG-320A, with full retainment of their noteworthy merits. It is operated by hand and can be controlled and actuated either by power or by hydraulic system.
2. In comparison the machine is superior to UG-320A in the following field: greater rigidity and resistance to temperature change deformation of the machine body; large diameter for the grinding wheel spindle; Two sets of bearing consisting of four-shoes used as wheel spindle bearings, more power of the grinding wheel and use of small orifice lubricant restrictor for better table lubrication. All these improvements result in higher efficiency and better finsih in grinding performance.
3. Machine table longitudinal travel, wheelhead rapid approach and withdrawal and automatic periodic cross infeed are driven hydro-electrically by pushing button operation. The machine also has the following functions: hand-operated worktable and wheelhead manually traverse infeed plus hydraulic tailstock quill retraction by foot.
4. The headstock can be swiveled in counter-clockwise direction in 90 degree range. By swiveling the headstock, or wheelhead or table, components with different external or internal taper can be ground. By turning down the internal grinding attachment, internal surface of components can be provided for grinding selection. The chuck mounted using short axis.
5. Workpiece, external and internal grinding wheels, hydraulic and coolant pumps are all driven separately by individual motors.
6. All the power moving portions of the machine are interlocked by electro hydraulic mechanism to ensure safety in operation. External and internal grinding wheels are guarded in sound and strong covers.
