"NEW" ACER HIGH PRECISION SURFACE GRINDER
 MODEL: Supra-618-II
 
 FEATURES:
 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 roller 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 without 
 backlash for more convenient operation.
