GF-type centers are special designs with fixed
point and a bearing-mounted rotating head.
The radial and axial loads are absorbed by
several heavy-duty, adjustable roller bearings.
They supplement the DA-series for workpieces
with even larger bores. Unlike the other types,
the GF center is only supplied with an angle of 75°.

DH-types are equipped with a carbide
tipped point and are recommended for
machining operations where the live center
is subject to frictional wear such as when
workpieces are changed at full speed.

DM-type centers are due to their short point designed
for extra heavy workpiece. The load ratings listed in
the table apply only if dimension E is maintained and
a Z-type support disc is used. (Please order the Z-type
support disc separately).
If the speed is increased, the axial pressures must be
correspondingly reduced.

DV-type centers are specifically designed
for use on CNC machine tools and copying lathes.
Because of the extended point they can be used
for work-pieces with smaller diameters. When
machining eccentrical workpieces please note that
the specifications concerning workpiece weight
and speed must be correspondingly reduced.
