Guide Head Setting Procedure
Raise the saw blade approx. 20 mm above the fixed gripping jaw of the
vice. Switch off the master switch, isolate the machine from the supply and
secure it against restarting. Disconnect the supply hoses of the guide heads;
with ARG 500, dismantle also the whole carrier with the pressure control
head. Unscrew the guide heads gradually from the fixed and moving guide
bars and clean them thoroughly. Attach the guide heads to the fixture
approx. 300 mm from each other and turn them through 180° (bearings and
carbide guides upwards). Observe the perpendicularity of the guide heads
towards the guide bars and the identical height of the guide heads. Check
the tightening of the fixed carbide guides. Insert approx. 40 cm of an old
saw blade between the carbide guides and the bearings. Set the pressure
carbide guides with the setting screw of carbide guide width so that the saw
blade moves without clearance between the carbide guides, but does not
seize. When the saw blade is correctly set, adjust the eccentrically arranged
bearings to prevent the bearings from “cutting” the saw blade, but it must
not be loose between the bearings either. When the saw blade moves, the
bearings are carried along by the saw blade. Check all the bolt connections
for tightening. Unscrew the guide heads from the fixture. Fit the saw blade
on the moving wheels, check its correct alignment on the moving wheels
and tension the saw blade. Install both guide heads on the saw blade in the
space between the bars and adjust them in the correct position on the bars.
Than we move guiding heads up, so that the space between fixed carbide
guides and upper part of saw band was approx 0,5-1 mm. In this way, the
correct height of the guide heads towards the bars is set. Adjust the guide
heads so that the saw blade should be in perpendicular position towards the
machine table and tighten the saw blade. Connect the hoses of the cooling
system and the saw blade pressure guides. Close the band saw head guards,
switch on the master switch or connect the machine to the network. Switch
on the hydraulic unit and carry out a short test run of the saw blade. Switch
off the master switch, isolate the machine from the supply, open the band
saw head guards and check if the saw blade fits on the moving wheels and
