Serial No. S6932001     New - 2004
 
 
GENERAL INFORMATION:
The Chevalier SMART H818II -
 "Microsoft WinCE Platform, 2-Axis 
 Conversational CNC. Semi-automatic or manual 
 operations use hydraulic drive for 
 longitudinal table movement.
 Conversational factory-programmed canned
 cycles, simple conversational graphics 
 with preview function and 
 surface/plunge/crisscross/profile grinding modes.
 Programming, a graphic program
 input function avaialable for grinding 
 and dressing with auto compensation, 
 
 It is easy to operate and can combine the
 grinding  cycle, wheel dressing and auto 
 compensation without using a CNC program. 
 The wheel dressing can be executed
 during the grinding cycle. It can simulate 
 the grinding path and dressing cycles by
 turning the MPG handwheel. 
 It can Grind multi-slots with different
 pitch and depth. 
 Conversational and G-code programs can be saved on
 a hard drive or floppy disk. It is FANUC CNC Program 
 compatible and has a patented longitudinal stroke
 adjustment from the screen.
 
• High precision spindle is supported by 
  four pieces of class 7 (P4) super precision
  angular contact ball bearings and directly 
  coupled with low vibration class V3 spindle 
  motor, suitable for heavy duty grinding 
• Counterweight balance device on spindle 
  housing to reduce load burden • Headstock 
  elevation accuracy is adjusted by gibs and
  designed with counterweight balance device 
  to ensure the micro downfeed accuracy 
• Base and saddle, specially designed 
  one-piece T-shaped base casting offers
  superior rigidity 
* Precision C3 grade ball screws on cross feed 
  and down feed axes directly mounted via 
  coupling to the Mitsubishi® AC servo motors 
• Hand scraped, Turcite B coated crossfeed 
  guideways between base and saddle have double
  "V" design, provides support for full table
  travel and prevents table overhangs 
• Hand scraped, Turcite B coated longitudinal 
  ways between table and saddle are double 
  "V" design, ideal for delicate side grinding 
  operations 
• Hydraulic creep-feed function. Hydraulic 
  Table longitudinal movement speed can be 
  adjusted easily by turning two knobs 
• Quick lock/unlock mechanism. Hydraulic cylinder 
  can be disengaged very quickly for quick fixture
  alignment 
• Recirculating forced lubrication system 
  on all guideways
