A sizable investment is made on these tooling. They have been manufactured to precision tolerances and should be handled accordingly. It is most important that the operator and set-up man realize how much money they are handling, when they pick up a knife or distance ring.
The following points should be taken care of for getting the best out of the slitter tooling :
(a) While setting the knives & distance rings, ensure that all the components are cleaned properly. Arbors should be cleaned & oiled.
(b) When mounting, removing and storing knives, cutting edges and surface must be treated with extreme care.
(c) Knives must be reground regularly. Please do not use blunt knives for the slitting operation - this will cause excessive load on the knife edge and there are possibilities of their chipping off.
(d) All the knives should be ground in a set and variation in O.D. should be within 0.02 mm.
(e) Since the material of the knives is hard, a suitable grinding wheel should be used for the grinding of knives.
(f) While regrinding the knives, use enough coolant.
(g) While slitting the material, ensure that the check nuts of the arbors are tight.
