When manufacturing wire, bar steel and rebar, the highest quality standards apply regarding precision and surface quality of grooves in rolls and roll rings, especially in finishing stands. In order to machine rolls and roll rings efficiently and economically, tight tolerances have to be met.
The solution: groove grinders made by Herkules. Using deep pass grinding and contour grinding for grinding grooves in carbide rings achieves the highest shape accuracy and surface quality in very short machining times. A long table version of the machine allows for the machining of composite rolls. In combination with a notch milling device, the grooves can be provided with notches for rolling construction steel.
