About FISCHER Machines
FISCHER in this context refers to the Swiss center-hole grinding technology historically associated with Fischer Dottikon and often described as System Fischer. The name remains familiar to buyers seeking specialized equipment for restoring or producing accurate center holes before cylindrical, thread or gear grinding. Current machines using this operating principle are offered under the ZAMAG name by Switzerland-based Zeller Automatik AG.
Unlike a general-purpose surface or cylindrical grinder, a FISCHER center-hole grinder prepares the reference points that support a rotating workpiece between centers. Heat treatment can distort a shaft and its original center holes. Regrinding those centers helps establish a more accurate axis for later finishing operations and can reduce the amount of stock that must be removed during cylindrical grinding.
System Fischer machines use a rotating grinding pin, an oscillating or stroking movement and a rotating workpiece to create a cross-hatch finish inside the center hole. Depending on the configuration, a steady rest may be used for pre-ground components, while an adjustable precision chuck can help align rough, non-round or intentionally offset workpieces.
Typical applications include machine spindles, motor shafts, gears, ball screws, hydraulic components, toolholders and aerospace or automotive shafts. Their focused purpose and relatively limited availability help keep established FISCHER ZSM machines relevant to specialized grinding departments and rebuild projects.
