The milling head requires seven (7)
machining inserts. Each insert is
held in place with a screw and can
be replaced or repositioned as
needed. The insert key is used for
these screws.
Assemble the milling head casing (2.2) and the milling unit holder (3), then use the drive ring
(2.3) to regulate the bevel depth. On the drive ring, one unit corresponds to 1 mm.
MILLING UNIT HOLDER
The milling unit holder or bracket head assembly mounts to the carriage and positions the
milling unit at a fixed angle. The milling unit holder must be changed to change the bevel angle.
The standard SPB-3000 package includes four (4) holders -- 0º, 22.5º, 37.5º, 45º. Holders are also
available for 15º, 20º, 25º, 30º, 55º, and 60º. Figure 5 shows the major features of the milling unit
holder.
