1. Control power supply switches
and indication lamps.
2. Provide left end / right end
table parking selection.
3. Pilot lamp shows that fine
grinding is performing.
4. L.E.D. digital screen
shows "Y axis position"
5. "WHEEL LIFT UP TO" switch:
Grinding wheel lifts up to start
point or reference point after
grinding cycle is finished.
6. Z-axis stroke can be set by
using setting key.
7. Selections steps for wheel
dressing interval.
8. "DRESSING OFFSET"
provides the first dressing
compensation percentage.
The percentage is chosen
according to operator's
grinding experience. The
percentage of dressing
compensation will be
performed right after
dressing is complete.
The balance will be
compensated at next
downfeed increment.
9. Separate switch provides
crossfeed increment for
rough and fine grindingTotal removal amount can be set by
pushing the "+" or "-" to increase or
decrease each digit..
Fine Grinding
Increment Selector
To set crossfeed reversal points,
move saddle to desired "in"
reversal position & press stroke
set and repeat afore mentioned
steps to set desired "out" reversal
position.
The Start of line grinding can
be selected and the range is
0"~0.0020" (0μ~40μm)
A rough crossfeed increment is
set for rough grinding, and fine
increment is set for fine grinding.
Each setting corresponds with
rough and fine crossfeed
increments.
Table speed can be adjusted by
table speed control lever from
16~82FPM (5~25m/min).
The operator can set the dress
amount from 0.0002"~0.0008"
(0.005mm~0.02mm), dressing
passes across the wheel from 1
to 4, and dress frequency during
rough and fine grinding. The
wheelhead position is automatically
compensated during AUTO
dressing (optional).

Rough Grinding
Increment Selector 3The machine with micro-processor is programmed to perform
rough grinding, fine grinding sparkout passes, automatic overwheel
dressing and compensation for wheel dress amount. After grinding,
table can be set to park either left end or right end. Spindle can be
set to stop running or keep running and wheelhead can also be set
to lift up to start point or reference point after grinding cycle finished.
The machine is suitable for mass production.
Precision Spindle And Rigid Elevating Guideways
The rigid wheelhead houses a large diameter cartridge type
spindle supported by 6 super precision class 7 (P4) permanently
lubricated angular contact ball bearings (4 pcs for 20 series).
The precisely balanced spindle motors are air cooled to ensure
optimum surface finishes and maintain superior accuracies.
Automatic Wheel Dressing With Compensation (Optional)
The machine efficiency is maximized by automatic dressing with
automatic dressing compensation during rough and/or fine grinding
and at the end of rough grinding. This allows machine to run
unattended, and reduces machining costs.
Completely Supported Guideways
Extended base guideways for crossfeed and longitudinal travel
enhance machine rigidity & stability and upgrade machine accuracy
& longevity. The permissible loads can be completely supported and
table overhang is eliminatedAll essential casting are made of high grade dense
cast iron which has been stress relieved and ribbed
with honeycomb ribs to enhance rigidity
and increase stability thereby increasing cutting
capability.
Crossfeed Stroke Setting
The crossfeed travel is set with push buttons on
control panel. This new break through in design is
more efficient and user friendly.
AC Servo Vertical Drive
The wheelhead, travelling on hardened and ground
square ways coated with Turcite-B system is
cooperated with hardened and ground leadscrew
(20 series) and precision ballscrew (24 series), and
an AC servo motor to provide high torque, speed
and accurate positioning with a minimum increment
of 0.0001" (0.001mm). A manual pulse generator
(MPG) is standard for easy operation.
Crossfeed Speed Control
Column continuous movement speed is controlled
by a frequency converter for obtaining better
grinding surface finish and better dressing result
from table.
