GENERAL FEATURES:
- High Precision Cartridge Wheel Spindle:
High precision cartridge type spindle is supported by two preloaded precision angular contact ball bearings & one NN type Roller bearing and driven by V3 class motor that allow high accurate grinding performance. (618/818 series are driven by 2.0HP motor.)
- High Anti-Wear Guide Ways:
The saddle rests on precision hand-scraped double V ways, and the table rests on precision hand-scraped V and flat ways which coated with “TURCITE-B”. These guide ways are equipped with auto lubrication to resist wear of guide ways, plus lasting accuracy and damping.
- High Rigid Casting Construction:
Machines are casted with high grade casting iron with heavy walls and reinforced ribs to provide excellent rigidity and damping.
- Enlarged Column And Base:
Enlarged column and base create high stability and rigidity. The height of column is increased up to 18″ (460mm) from table surface to the center line of spindle.
- Auto Lube System:
Automatic lubrication system is applied as standard to ensure sufficient lubrication at lead-screws and guide-ways for more longevity.
- Longitudinal & Cross Drive:
For all models, except 618 & 818 handfeed, the longitudinal movement is driven by hydraulic system; for 2A, 3A, ASD series, the cross movement is driven by motor for more accurate increment feeding.
