The rolls meeting all the stringent tests to our complete satisfaction are then sent to the rest of the machine-shop, comprising high precision lathes, radial drill machines, boring machines wobbler milling & grinding machines, etc. Special purpose milling machines for accurate machining of wobbles and the driving end, and Roll Grinders equipped with special concave and convex device, capable of grinding roll necks (both tapered and straight) to extremely close tolerances are the essential part of our work-shop.
The high precision boring machines guarantee highest accuracy in regard to roundness and concentricity of the bore. In our machines one would find a mix of some of the best Indian & International names for precision machining, grinding and drilling.
Meanwhile all the steel rolls require heat treatment. The hardening and tempering furnaces are provided with temperature control microprocessors and the required rolls are subjected to various heat treatment cycles. Stress relieving of special S.G. IRON ROLLS is also done here. Metallurgical tests in respect of grain size and micro-structure are carried our after heat treatment and eventually the ultrasonic testing is done, where required, to ensure the overall internal soundness of the roll. Hollow rolls are dynamical balanced at different RPM to ensure their friction free movement.
