19.4.5 Clamping the tool in the tool holder
The main function of the tool holder is to fix the tool. If necessary, the tool holder can also hold
more than one tool (maximum 4).
When inserting the tool, make sure that the cutting head of the tool points in the direction of the
rotation axis of the workpiece.
Align the turning tool in height. Use the tailstock with centring point to determine the
required height. If necessary, place steel supports under the lathe tool to obtain the
required height.
19.4.6 Mounting Steady/Follow Rest
Use a steady and/or follow rest when the cutting force of the turning tool is likely to cause the
turned part to deflect.
19.4.7 Levelling Tailstock to Headstock
Clamp a 200 mm long solid pipe piece correctly between the spindle and tailstock.
Now clamp a dial indicator into the tool holder.
Use the manual feed (handwheel) to guide the top slide along the workpiece. If there are
measuring differences, adjust the tailstock to the headstock using the adjusting screw so that the
measuring differences no longer appear on the tailstock.
HOLZMANN MASCHINEN GmbH
Clamp the turning tool into the tool holder.
The turning tool must be clamped as short and tightly as
possible in order to be able to absorb the cutting force occurring
during chip formation well and reliably.
Also ensure that the turning tool is clamped at right angles to
the axis of rotation (see illustration on the left). When clamping
at an angle, the turning tool can be pulled into the workpiece.
The cutting edge of the turning tool must be set exactly to
centre height during facing so that the face is free of studs.
Facing produces flat surfaces perpendicular to the workpiece axis
of rotation. A distinction is made between transverse face
turning, transverse cut-off turning and longitudinal face turning.
If the tool holder must be turned, open the clamping lever by
turning it counterclockwise. Turn the tool holder to the desired
position and then tighten it again by turning the clamping lever
clockwise.
