To install the support for J-beveling, loosen the screw
5
using the 8 mm hex
wrench and loosen two lock levers
6
, set the body to a proper height indicated by the
scale
7
, and tighten the screw and levers. Then, install the milling head for J-beveling
in the manner shown in Fig. 9.
Install the milling unit in the manner shown in Fig. 4.
To face the plate using the support for beveling 36
–70 mm plates at the angle of
0° to +60°, perform the first pass with the milling unit in the lowest position (
8
,
Fig.
10), and then the second pass at the indication of ‘0’ (
9
).
Before J-beveling, prepare the plate as shown in Fig. 11 using the standard milling
head. Then, replace the milling head to a special R6 or R8 milling head for J-beveling.
During J-beveling, the carriage must travel to the left, which will reduce vibrations,
increase the life of the cutting inserts, and improve the quality of the surface. When
performing multiple passes, before every next pass, place the carriage again on the
right
side
of
the
plate,
and
increase
the penetration of the milling head in the workpiece.
Establishing J-bevels may require several stages (Fig. 11) depending on the plate
thickness. After completing every stage, lower the milling unit, secure the support in
this new position, and perform the next stage. Proceed as described until the J-bevel is
established.
