Standard features:

High precision 3 axis fully automatic programmable
Controlled model, the grinder is suitable for mass production

The machine with micro processor is programmed to perform rough
Grinding,finegrinding sparkout passes, automatic overwheel dressing
And compensation for wheel dress amount. After grinding, table can be
Set to park at left end or right end for part inspection

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

Rigid construction, all essential castings are made of high
Grade meehanite® cast iron which has been stress relieved
Through annealing to eliminate internal stress and ribbed with
Honeycomb ribs to enhance rigidity and increase stability
Thereby increasing cutting capability.

High precision cartridge type spindle is supported by
Four pieces of class 7 p4 super precision angular contact ball
Bearings which have been accurately measured, selected and preloaded,
And then assembled in a temperature controlled room.

The spindle is permanently lubricated and requires no maintenance.
Spindle motor, spindle shaft, and couplings are
Precisely balanced to ensure accuracy and superb finishes

Ac servo vertical drive, the wheelhead travelling on a preloaded
Linear guideway system is driven by a hardened and ground
Leadscrew and an ac servo motor providing high torque, speed and
Accurate positioning with a minimum increment of 0.0001".
A manual pulse generator (mpg)is standard for easy operation.

3 axes needle roller slideway, all three axes guideway rails are
Composed of s55c steel that is normalized then hardened by high
Frequency induction. The guideways are 60 - 64 hrc after heat treating.
Precision roller bearings run through a sieve to select exactly matched
Sets which are preloaded between the linear guideway to provide
A guideway system that will ensure excellent accuracy and
Precise positioning with stick-slip free movement

Elevating guideway system, the wheelhead and column way system
Is composed of hardened and ground inserted steel guideways
And precision roller bearings.

The wheelhead and column guideways are preloaded providing
Zero clearance for precise straight line movement.
The low friction wheelhead guideway system enables accurate
Feeds even at 0.00005" increments while providing extended way life.

Table guideway system, the table guideway system is composed of
Hardened and ground steel guideways with precision needle
Roller bearings to provide
excellent longevity and low friction,
And also to provide precise linear movement without deviation,
Even during rapid traverse movement.

Saddle guideway system, the guideway system of the saddle is
Composed of specially designed preloaded needle
Roller bearings and hardened and ground slide rails.
The roller bearings consist of independent loading and leading bearings.
Loading bearings are to support the vertical load and preloaded
Leading bearings are to assure accuracy of the cross movement of saddle.
The combination of these two features provide excellent
Longevity and low friction, stick-slip free accurate movement.

Crossfeed transmission, the saddle incorporates a specially

Micro crossfeed device, the micro crossfeed device consists of a
Once the worm and wormgear are engaged, the cross powerfeed motor
And the cross handwheel are automatically.
Speed is controlled by a frequency converter for obtaining
Better grinding surface finish and dressing grinding wheel
From table as options.
All switches, buttons, leds, indicating lamps, and displays
Are ergonomically positioned providing user friendly operation

Automatic lubrication system provides lube oil to saddle ways,
Separate hydraulic system prevents vibration and reduces heat
The interlock between electrical cabinet door and power
