8.1 Blades
8.1.1 The blade clearance (blade gap) adjustment:
It is a very important factor to adjust the blade clearance which relates the cutting quality and knife life. Pls follow below procedures: the clearance data is 0.07~0.1 times of the plate thickness, the plate thickness =0.07~0.1t. The above is for Ob=450-500N/mm
2
. For more
than450-500N/mm
2
, it is suggested to use smaller clearance. And for less than 450-500N/mm2, pls use larger clearance. Turn the handwheel in the front of the plane board to adjust the clearance data. That means adjust the clearance according to the plate thickness. The data will
be displayed on the handwheel
8.1.2 measuring of blade clearance and adjustment of the proportional clearance
the proportional clearance relates the cutting quality directly. It is set up by the manufacturing and unnecessary to modify normally. After the machine has been used for a period of time and if the knife side is changed, then it is a must to adjust the blade clearance again . The
adjustment procedure is as below: turn the switch to adjust mode, adjust knife beam to balance( cutting angle is 0, Turn the clearance adjust hand wheel anticlockwise to the “smallest clearance”, turn off main motor(power on), press oil filling button, move knife beam down until
distance between upper and bottom blades is 3~5mm, adjust the bolts and nut which support bottom blade on work table, use the plug gauge to inspect the clearance. After the adjustment is finished, repeat reset course of knife beam(5.2.C).
8.1.3 The installation of the blade
After the machine has been used for a period of time, must turn over the blade sides
or change the blade. The installation of the upper blade is as below: make the upper
knife beam flat( the cutting angle is 0 ). Then turn off the screw at the lower knife to
change the blade or turn over the blade. (be careful of the sharp blade to avoid hurt.)
it is easier to change the lower blade.Just take off the upper blade cover at the
working table and turn off the screw to change the blade or turn over the blade.
