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: Hydraulic Table.
