Goodway gru/gra/grw cnc cylindrical grinder

Goodway  GRU / GRA / GRW Series CNC Cylindrical Grinder

Grinding wheel Spíndle Supported by Hydro-static Bearíng
The grinding wheel spindle is precision machined from Nickel Chromolybedenum
alloy steel SNCM-220 . lt is supported by hydro-static bearing, which greatly upgrades the spindle running stability while reducing temperature growth to a minimum.
Hydro-static Lubrícatíon on X Z axes Slideways
The cross and longitudinal slideways for the grinding wheel head are lubricated
by a hydro-static automatic lubrication system. This outstanding lubrication
system allows for extremely smooth movement of the grinding wheel head,
accurate feed and ensures high grindíng accuracy.Advanced Construction Design X-axis with hand scraping extra large V type guide way to ensure the best
dynamic accuracy and balance loading.
C1 class X-axis / C3 class Z-axis hardened precision ground ball screws ensure the highest accuracy and durability possible. Plus, pretension on all
axes minimizes thermal distortion.
1 X Z axes are all V type guide way design on GRW series
