SLIDEWAYS
Table (Z) and Wheelfeed (X) Axes are guided by low friction coated vee and

flat slideways with positioning by servomotors, preloaded ballscrews and

rotary encoders.

WORKHEAD
The workhead is a swivel base, live and dead center type. A servomotor drives

the spindle, which rotates in high precision preloaded tapered roller bearings

and offers speed selection within a range of 1 - 660 RPM.

TAILSTOCK
Housed in a cast body, the hardened nitralloy steel sleeve carries a removable

center. Sleeve movement is by a lever and can be adjusted for light or heavy

loads.

WHEELHEAD
The universal wheelhead includes independent external and internal wheel

spindle drives. The hardened and ground wheelspindle rotates in two pairs of

angular contact rolling element bearings.

WHEEL DRESSING
Dressing can be accomplished using the table dresser unit or the tailstock

diamond.

Dressing Operation
After set up, dressing can be undertaken before or after a grind cycle as

required simply by selecting dress mode, moving the table to the dress

position (assisted by the displays) and pressing cycle start. The amount that

the wheel diameter reduces by dressing is compensated for automatically. When

changing from grind to dress land (vice versa), a double register ensures that

axis displays are stored and then recalled with the appropriate mode.


ELECTRONIC CONTROL
Grinding cycles are very easy to program, using step by step parameter

prompting with default values which can be accepted or amended as required.

At the end of a cycle the wheel retracts automatically. For manual operation,

precise control of table traverse and wheelfeed is by hand pulse generators

(HPG's) and the position of each axis is clearly indicated on digital read

outs, which also display parameters.
