The new Hauser™ 2000, the successor to the H35-400 model, is a universal jig grinder with proven technical features such as automatic taper grinding, automatic grinding tool changer (ATC) and automatic pallet changer (APC). It can be expanded easily to an autonomous grinding unit. The Hauser 2000 not only meets the demand of the market for combined grinding and hard milling on a single jig grinder, but also enables further improvements in machining precision to meet future requirements. The main technical feature is the dual-frame design, which significantly increases the rigidity of the grinder and therefore ensures even higher precision. In this box-type design, the machining head is positioned centrally within the machine frame, thus enabling machining forces to be optimally controlled. Almost no transverse forces are created – the prerequisite for ultra-high geometric precision machining. Since the tool machining point is located at the center of the machine, practically all thermal expansion effects are eliminated.

With higher dynamic axis movements and significantly greater rigidity, the Hauser 2000 gives the best possible conditions for finishing with hard precision milling.The overall result is a significant increase in productivity not only for the ultra-precise grinding processes on the machine but also for hard milling.
