"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.
