HI-GRIND200-II Middle Size High Speed Hydrostatic Centerless Grinder
1. Cost-effective machine with high accuracies, high efficiency and high productivity
  a)Hydrostatic bearings are applied to both wheel head.
2. Hydrostatic bearings offer advantages;
  a)no abrasion
  b)extremely low friction and low temperature rise
  c)high oil film stiffness independent on the number of rotation
  d)precise and constant rotating accuracy
3. Open sided support is applied for GW spindle for convenient changeover operation.
4. RW table is driven by CNC for consistent infeed cycle and high accuracies.
  a)Beginners are able to make infeed cycle patterns by using easy to understand Macro variables.
  b)Reliable V and flat guideway is applied for RW table, which is based on long experiense, rich achievements and veteran craftsmanship.
  c)Mechanical compensation is available for thru-feed grinding. (Option)
