This is a large size surface grinder suitable for grinding big, heavy work piece. To ensure smooth and steady movements, the cross travel is designed by having the vertical column travels in and out instead of the saddle. The table and column travels on T-shaped one piece casting base with TURCITE coated sideways.
- For cross travel, the vertical column travels in and out instead of a saddle. This design offers more accurate grinding for large, heavy work piece
- The length of the bed ways are twice the table length to ensures no overhang of the table.
- Longitudinal and cross slide ways are hand-scraped and Turcite coated for high wear resistance and smooth table and column movements
- Hydraulic longitudinal table movement
- Motorized cross column movement with solid state relay.
- Spindle rapid traverse is standard. NC down feed is optional
- Free standing hydraulic units prevents heat and vibration from causing grinding inaccuracy
- Two single action hydraulic cylinders and piston rods ensures stable table motion.
