GRINDING MACHINE FOR BLOOMS, BLOCK, BILLETS

Custom manufacturing and supply of grinder for the grinding of surface defects of slabs, blocks, billets and round continuous castings. It’s an effective way to achieve a pure surface of the material before further processing – hot rolling. Grinding is divided into two types: full-area or local, depending on the material quality or the occurrence of surface defects. Grinding also includes the beveling of the front part of the ground material.

Grinder type::

Stationary grinder with travelling bench
Travelling grinder with stationary bench

Operational regimes::

Automatic – a new series of grinder also offered in fully automatic operation, incl. the control of surface defects by a profile laser
Semiautomatic – grinding of the billet area. Loading, dispatching and turning of billets, grinding of the edge ends is manually performed
Manual – all movements are performed manually
