Engaging Lever; Lathe Saddle With Cross And Top Slide; Immobilizing The Lathe Saddle; Turning Tapers With The Top Slide - Jet BD-11G Operating Manual

Immobilise the quadrant with the locking screw.
Attach the protective cover of the headstock and reconnect the machine to the power supply.

5.7.3 Engaging lever

O The automatic longitudinal feed and the feed for thread-cutting are activated and deactivat- ed using the
engaging lever. The feed is transmitted via the leadscrew nut.
Push the engaging lever downwards.
The leadscrew nut is engaged and the automatic longitudinal feed is activated.
Move the handwheel slightly to lock the engaging lever in place.

5.8 Lathe saddle with cross and top slide

The handwheel is used to manually traverse the lathe saddle.
The cross slide can be advanced and returned by turning the cross slide hand-
The top slide (tool slide) supports the quad- ruple toolholder.
Use the top slide handwheel to move the corresponding slide.
5.8.1 Immobilising the lathe saddle
The cutting force produced during facing, recessing or slicing process may displace the lathe saddle.
Secure the lathe saddle using the tight- ening screw.

5.8.2 Turning tapers with the top slide

It is possible to turn short tapers with the top slide.
Loosen the two nuts on the left and the right of the top slide.
Swivel the top slide.
Clamp the top slide again.

5.8.3 Cross-adjustment of the tailstock

The cross-adjustment of the tailstock is used for turning long, thin bodies.
Loosen the locking nut of the tailstock.
Unscrew the locking screw approxi- mately half a turn.
By alternately loosening and tightening the two (front and rear) adjusting screws, the tailstock is moved out of the
central position. The desired cross-adjustment can be read off the scale.
First retighten the locking screw and then the two (front and rear) adjusting screws.
Retighten the locking screw of the tailstock.
ATTENTION!
Check clamping of the tailstock and the sleeve, respectively, for turning jobs between centres!
Fit the securing screw at the end of the lathe bed in order to prevent the tail- stock from falling off the
lathe bed.

5.9 Tailstock sleeve

The tailstock sleeve is used to hold the tools (bits, lathe centres, etc.).
Clamp the required tool in the tailstock sleeve.
O Use the millimetre scale on the sleeve to readjust and/or adjust the tool.
Clamp the sleeve with clamping lever.
O Use the handwheel to move the sleeve forward and back.
The sleeve of the tailstock can be used to introduce a drill chuck for holding bits and counter- sinks.

5.10 Clamping a workpiece into the lathe chuck

When the workpiece is being clamped unprofessionally, there is a risk of injury as the workpiece may fly off or the
jaws may break. The following examples do not show all possible situations of danger.
The workpieces are to be clamped safely and tightly on the lathe before starting the operation. The clamping force
is to be dimensioned in a way to make sure that the workpiece is securely driven and that there are no dangers or
deformations on the workpiece.
WARNING!
