HIGH PRECISION CARTRIDGE SPINDLE: High precision cartridge type spindle is supported by 4 high precision preloaded angular contact ball bearings and is driven by V3 class motor that allows high accurate grinding performance.

HIGH ANTI-WEAR GUIDE WAYS: The saddle rests on precision hand-scraped double V Turcite-B ways; the table rests on precision ball rolling ways. These guide ways are equipped with an auto lubrication system to resist premature wear and they are hand scraped or hardened & ground to 1/10,000" per 12".

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: An enlarged column and base creates high stability and rigidity. The height of the column is increased up to 19.3" from table surface to the center line of spindle.

TABLE DRIVE: For handfeed models, the table drive makes use of cable which encloses high tensile steel cores that ensures more smooth table movement and longevity. The table handwheel can be indexed to 9 different positions withou backlash for more convenient operation. (618AH II has hydraulic table.)
