  B. The method of slitting adjustment

  a. Lift up the upper blade shaft by double worm gear and worm rob, to make center Stroke between the two blade shaft is greater than blade outside diameter, 2-12mm slitting machine: blade OD.: Φ480mm , center Stroke: ≥485mm

  b. Hydraulic pushing movable frame

  c. Determine the space between the upper and lower blade according to the slitting plate thickness.  Equation : S=thickness X(10━15)/2

  d. The method of blade arrangement : arrange the blade to the both side of center line according to the center line of production line, before arrange blade, the separated roll of blade should be cleaned debris, and don’t use hard wast,fiber to wipe. Arrange the lower blade first, and then arrange the upper ones, convex blade with big rubber rings, concave blade with small rubber rings, not too much or too little. After arranging blade shaft, make one side of lock nut locking. The cutting length of blade general take 1.0-2.0mm, and use positioning nut locking.

  e. Can’t use large hardness metal material to trial cutting, sharp cutting edge of blade shall not use objects to hit, temporary unused blade should be cleaned,and oiled to prevent the mental surface from rusting. The blade should be grind after using, and use core rod to grind the outside uniformly, strictly forbidden to grind the both side of blade.
