Featuring high rigidity with PRO/E analytical physics design and endurable mechanical stability, the Chevalier surface grinder range is certainly your best companion for high precision surface grinding jobs.
Technical Features:
Automatic lubrication of lead-screws and ways as these advantages can help to reduce friction and prolong machine life.
Work-piece flatness is guaranteed to be within +/-0.00012”(+/-0.003mm) over the entire working surface.
Spindle run-out is within +/-0.00060”(+/-0.0152mm) for superior accuracies and finishes.
Meehanite casting (including the base), ensuring excellent rigidity and superior
dampening during heavy machining |

Features:
The working table executes only longitudinal movements. Double V guide-ways are laminated with Turcite-B hand scraped to obtain smooth stick-slip free movements.
The column carries out only crossfeed movements. The column slide is guided by STAR roller linear guides, with C3 grade high precision ball-screws and driven by servo motor.
The spindle housing carries out only vertical movements. The Y-axis is also guided by STAR roller linear guides, with C3 grade high precision ball-screws and driven by servo motor.
The flanged cartridge type spindle is supported by 3 pairs of class 7 super precision angular contact ball bearings, preloaded and select-fitted into spindle cartridge.
The dresser is mounted on right side of table. Auto surface grinding cycles and dressing cycles with compensation are standard.
The automatic re-circulating lubrication system supplies lubricant to all of the guide ways and lead screws as the machine operates.
The external independent hydraulic tank is located outside the machine to be easily accessible for maintenance. Driven by the proportional valve hydraulic system for easy speed adjustment in a range of 2~30meter/min for most surface grinding applications.
The oil cooler unit is standard for hydraulic system to prevent the temperature rise, and thermal deformation can be reduced to minimum.
An independent control box with an ergonomically designed panel offers a comfortable and convenient operation environment.
Modern 10.4" color LCD touch screen panel, simply touch the screen to set the grinding variables.
Manual Pulse Generator (MPG) is also provided for user's convenience for both down feed and cross feed.
Sizes available from ( 500~800 )mm by ( 1000~2000)mm.

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 |
