Cross Slide - WABECO D4000 E Operating Instructions Manual

9.4.1

Cross slide

The cross slide is situated at the front on a prismaticatic guide and at the back on a flat surface
guide. The slide is held to the bed from below by means of guide rail (46). At the front on the RH
side is the cylindrical screw (39). With the help of this cylindrical screw, clamp (76) can be clamped
up against the underside of the prismatic guide. This clamp is suitable for transverse turning and
slicing.
The dove-tailed guide of the cross slide can be adjusted. If you wish to make an adjustment, then
first you must loosen hexagonal nuts (12). Tighten threaded pins (45) so that the slide can move
backwards and forwards along with ball-ended crank (57). After adjusting, tighten hexagonal nuts
(12) again.
You can also adjust any axial play which occurs in spindle (38) of the spindle bearing. If you wish
to make an adjustment first of all you have to loosen threaded pin (29). Now scale support (27) can
be turned to the right until there is no more axial play. Then tighten threaded pin (29) again.
After making the adjustment the spindle must still be free to turn easily.
For calculating the displacement path of the slide on scale support (27) there is a large scale ring
(29) divided into millimetres. One notch corresponds to 0.05 mm of adjustment and this corre-
sponds to the same amount of shaving on the workpiece. This means that in reality the slide is only
adjusted by 0.025mm, whereas the diameter of the workpiece changes by 0.05mm.
9.4.2 Top slide
The top slide is clamped via clamp ring (5) on the cross slide upper part (5). Loosen both screws
(operational elements Pos. 6) and the top slide can be pushed or turned along the cross slide. This
is suitable for lathing short tapered pieces. A scale is engraved on guide ring (2) so that you can
read the setting exactly. The zero line is on the cross slide upper part.
The dove-tail guides of the top slide can be adjusted as described for the cross slide. The parts
have a different numbering in the drawing: hexagonal nut (11), threaded pins (10), ball-ended
crank (24).
Likewise, as described in the case of the cross slide, the axial play of the spindle can be adjusted.
Here the parts are numbered differently: spindle (21), spindle bearings (19), threaded pin (26),
scale support (27).
