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.

terweight balance device on spindle
housing to reduce load burden adstock
elevation accuracy is adjusted by gibs and
designed with counterweight balance device
to ensure the micro downfeed accuracy
ase 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 Mitsubishir AC servo motors
d scraped, Turcite B coated crossfeed
guideways between base and saddle have double
"V" design, provides support for full table
travel and prevents table overhangs
d scraped, Turcite B coated longitudinal
ways between table and saddle are double
"V" design, ideal for delicate side grinding
operations
ep-feed function. Table longitudinal
movement speed can be adjusted easily by
turning two knobs
lock mechanism. Hydraulic cylinder
can be disengaged very quickly for quick fixture
alignment
circulating forced lubrication system
on all guideways
