Product Description
***G-630/G-800 cylindrical grinder is suitable for grinding the outer surface of cylinders and cones; UG-630 universal cylindrical grinder is suitable for grinding the outer and inner surfaces of cylinders and cones.
***The longitudinal movement of the workbench is driven by hydraulic pressure or hand wheel. The workbench can rotate at a certain angle and is suitable for grinding tapers.
***The transverse feed of the grinding wheel frame is hydraulically driven to achieve automatic periodic feed and rapid feed. Coarse and fine feeding can also be carried out through the handwheel. The workbench and grinding wheel frame guide rails are lubricated by static pressure, and the low-speed movement is smooth.
***The main shaft is supported by high-rigidity static pressure and dynamic pressure bearings, so that the main shaft has high rotation accuracy and perfect rigidity.
*** The workbench uses a variable frequency motor to achieve stepless speed regulation. The spindle of the UG-630 workbench adopts a sliding bearing structure.
***Front bearing clearance adjustable to suitCenter or chuck for grinding. With the UG-630, the work head can be rotated to any position within 90° of its counterclockwise direction, so it can be suitable for grinding the inner or outer surface of a cone. For UG-630, the cylindrical grinder has an internal grinding device, and the internal grinding spindle is supported by precision rolling bearings. ***The worktable spindle, grinding wheel frame spindle, internal grinding spindle, coolant pump, dynamic pressure oil pump and static pressure oil pump are driven by separate motors.
*** Each moving part of the machine is equipped with electrical, hydraulic, and mechanical interlocking structures. The machine is well designed and beautiful in appearance. All joysticks are concentrated on the panel, making it easy to operate.
***The grinding wheel dresser can be installed on the work surface of the tailstock.

Operation manual (English version)
The one-piece machine bed is made of high-quality cast iron, and the surface of the guide rails is hardened and precision ground for high stability and rigidity. Time has proven: the carefully designed structure guarantees excellent processing capabilities.
The abutment slideway is made of TF material and has been precisely scraped by hand; the grinding wheel head guide rail is a V-shaped flat rail equipped with linear rollers, which has high precision and low motion friction.
Cylindrical grinding of rotating parts
Comes with removable internal grinding device.
The grinding wheel frame spindle is supported by bimetal shell bearings, which gives the spindle high rigidity and stability, ensuring heavy-duty, excellent finishing surfaces.
The grinding head can be rotated 180° to realize the conversion between internal grinding and external grinding.
Centralized operation panel and reasonably distributed actions
The handle is very clear and user friendly
The machine is front friendly.
