6. Startup and Maintenance
6.7 Cross support
If adjustment becomes necessary, please proceed in the following manner:
1. Loosen the lock nuts.
2. Tighten the readjustment screws by using a socket head wrench until the slides can easily be
moved to and fro by means of the crank.
3. Re-tighten the lock nuts after the adjustment.
Longitudinal support:
The longitudinal support which is mounted to the transversal support is pivotable by 360°. Thus, it is
suitable for the turning of tapers. Adjust the position by loosening the two screws located on the
outer sides of the transverse support with a 4 mm allen key. The arrow on the transversal support
indicates the position of the longitudinal support in degrees. There is a degree scale on the
longitudinal support. The distance between two graduation marks represents one degree.
Graduated collars:
The support spindles are provided with graduation collars with graduation marks used for setting
the turning tools. One graduation mark represents a 0.05 mm feed adjustment which corresponds
to a 0.1 mm chip removal from the workpiece at the transversal slide and a 0.05 mm chip removal
at the longitudinal slide. The hexagon socket screw serves for locking the cross support to the
guide bars (e.g. in face turning.) The screw pulls the block at the bottom of the transverse support
against the two guide bars.
6.8 Tailstock
The tailstock is attached to the guide bars in such a way that it is slidable. It can be be locked in any
position by actuating the lower T-handle (4251). It can be separated into barrel and base. By
loosening the hexagon bolt (424), the tailstock barrel can be pushed to either side by up to 10 mm
and is, therefore, suitable for the machining of slight tapers. After completion of the taper
machining, move the tailstock to its home position.
The lateral mark indicates the central position of the tailstock. Find out by doing some trial turning if
the workpiece is cylindrical and correct the tailstock position if necessary.
Solid tailstock sleeve:
The solid tailstock sleeve, which is provided with a millimetre scale, is designed in such a way that
the lathe centre, drill barrel or chuck are automatically ejected during the backward motion.
Tool clamping:
An inner taper MT 2 is available for holding the tool. It is integrated in the sleeve. By tightening the
upper T-handle (4251), the tailstock sleeve can be clamped easily in any position. The sleeve can
be moved axially by the crank (31212) located at the rear end via the threaded spindle.
