18.6 Tool post
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.
Tool change
C A U T I O N
Before any manual tool change, stop the spindles, wait for all tools to come to a
standstill and secure the machine against unintentional restarting before changing
the tools!
Clamp the turning tool into the tool post (L).
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 a right angle to
the axis of rotation (see illustration on the left). When clamping
at an angle, the turning tool can be pulled into the workpiece.
Align the turning tool in height. Use the tailstock with centering point to determine the
required height. If necessary, place steel supports under the lathe tool to obtain the
required height.
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 post must be turned, open the clamping lever by
turning it counterclockwise. Turn the tool post to the desired
position and then tighten it by turning the clamping lever
clockwise.
18.7 Mounting steady or follow rests
Use steady or follow rests to support long turned parts if the cutting
force of the turning tool is likely to cause the turned part to deflect.
