8" x 18" Chevalier SMART H818II
CNC & Conventional Surface Grinder
with Full Factory Enclosure Option
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
