We at Dee tee engaged in the manufacturing of tooling for
various metal processing industries since 1975. While meeting the stringent
quality and tough application requirements of our reputed customers we have
acquired sufficient expertise and experience in optimizing the cost benefit
ratio of tooling consumed per ton of processing. This is a practical note,
based on our long experience in the manufacture of slitting line tooling,
which has been enriched by the meaningful customer feed back.

1. SLITTING KNIVES
In case of slitting knives, because steel is to be cut by steel, the cutting
quality is the prime criterion for selection of its raw material. The knife
material should necessarily by harder than the material to be cut. Along
with hardness, the knife should be sufficiently tough so as not to deform
during cutting. The knife should be in a position to retain the cutting edge
under load.
In addition, from the manufacturing point of view, the steel should be such
that it can be hardened in depth, and should retain its dimensions for long.
The thickness of the material to be cut can vary from 0.1 mm to 20 mm.
Hence, the cutting loads to which the slitting cutter knives are subjected vary
considerably. Besides thickness, the tensile strength of the material to be
cut, also affects the loading on the slitting knives. In general the thinner
the material to be cut, the higher should be the hardness of the slitting
cutters, for
same knife material.
2. SPACERS
The best suited raw material for spacers is Ball Bearing quality steel.
Spacers do not transmit any load and hence wear resistance and retention of
dimensions are the only criteria. Spacers should be having parallel and flat
faces for better performance.
3. OVER ARM SEPARATOR DISCS
Both impact strength and wear resistance should be for separator discs.
4. RUBBER RINGS / RUBBERIZED SPACERS
In a slitting line, these rubber rings / rubberized spacer come in close contact with the strip being
cut which is normally smeared with oil and carries the coolant. Therefore,
the rubber should be wear resistant, and should not get spoiled while in
contact with different oils.
