4.10 Installation on a lathe
The mill head with column can be mounted on a
lathe. For fastening an adapter is required.
The adapter needs to be fixed to the engine bed. It is
not possible to fix it to the lathe slide. The adapter is
dimensioned in a way that the middle of the lathe
chuck should be reached with the center of the
milling spindle (alignment headstock – lathe chuck).
Due to the manufacturing tolerances of castings and
the manufacturing tolerances of two different
machines it is however not possible to reach the
exact center, the adapter may be too long or short.
If required, the adapter is to be milled off or equipped
with dummy sheets. When using sheets the complete
surface is to be filled.
In order to reduce the support expenditure of the
column with milling head during the orientation we
recommend you disassemble the milling head off the
column. Unscrew the locking screw (safety screw) position 266. Disassemble the milling head
off the column by completely loosening the clamping screw and the lead screw and stripping off
the milling head.
Control the orientation (90° angle horizonal and vertical) of the column with the reference planes
on the engine bed of the lathe.
In order to prevent you from having to reorient the milling head when altering later on, we
recommend you to provide the column and the adapter as well as the engine bed with
alignment pins. If required, pin the column together with the cross table before disassembling
the column.
It is recommended to use hardened straight pins according to DIN 6325 in 8mm or 10mm and a
fitting tolerance zone m6. (zB. DIN 6325-8 m6 x 30). These alignment pins have a round cap on
one side which facilitates pinning together the parts. When assembled the boring holes must be
pilot-drilled to 0.2mm smaller and then rubbed with a reamer also when assembled. Ideally, use
a new twist drill with a diameter of 7,8mm for alignment pins of 8mm.
