MRV
with NC-Superplus-D control
or Siemens 840D control or Fanuc* control
(*USA and Far East only)
The advantage offered by the compact, rotary grinding machines of the MR family over longitudinal table machines, particularly when it comes to grinding small and mass-produced parts or round parts, is that there is no need for reversing the worktable.
Grinding area 500 to 2000 mm table diameter
Spindle drive 11 kW to 26 kW (horizontal/vertical)
Distance table to spindle centerline 700/900/1100 mm

Features:
Three axes automatic surface grinder with small footprint.
Castings are made of high quality ribbed cast iron, which have been tempered to achieve extreme rigidity.
X&Y slide ways are laminated with Turcite-B, hand-scraped with sufficient lubrication. ( 250AHD with ball bearing table and D-2 (SKD-11) slide ways).
The elevation guide ways (Z axis) are hand-scraped then secured to the column structure.
The spindle is supported by CP4 preloaded super precision angular contact ball bearings. This will guarantee a maximum run-out of 2 microns for heavy duty, stable and accurate grinding.
Separate hydraulic system with a specially designed valve enables smooth table reversing with a 26 meter/min table speed.
Automatic lubricating system to ensure smooth and long lasting operation in all 3-axes.
Automatic down-feed gearbox for accurate down-feed increment.
Sizes available from ( 250~400 )mm by ( 500~800 )mm.
