Table (Z) and Wheelfeed (X) Axes are guided by low friction coated vee and
flat slideways with positioning by servomotors, preloaded ballscrews and
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.
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.
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.
Dressing can be accomplished using the table dresser unit or the tailstock
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.
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.
