Handtmann PFZ 850 CNC

The Handtmann PFZ 850 CNC is a high-speed, high-precision machining center engineered specifically for aluminum structural components in aerospace and automotive applications. Handtmann, the German specialist in aluminum machining, designed the PFZ 850 to excel at the thin-wall pocket milling, hole patterns, and contoured surface machining that define modern lightweight structural assemblies.

The PFZ 850 employs a portal (gantry) architecture with the workpiece stationary on a generously sized T-slot table, while the crossbeam carries the high-speed spindle unit. This configuration eliminates workpiece inertia effects during high-acceleration moves, allowing the machine to sustain elevated feed rates across complex part geometries without sacrificing surface finish or dimensional accuracy.

A high-frequency spindle rated up to 30,000 RPM and paired with HSK-A63 tooling delivers the fine chip loads needed for aluminum thin-wall machining — preventing part deflection and achieving the surface quality that aerospace customers require. Handtmann's integrated clamping and fixturing systems complement the PFZ 850, enabling secure holding of complex profile extrusions and sheet metal assemblies.

The PFZ 850 is a mainstay in European aerospace supply chains, particularly for companies producing wing ribs, fuselage frames, seat tracks, and structural brackets. Handtmann's deep expertise in aluminum application engineering means customers receive not just a machine but a complete machining solution including tooling strategies, fixture concepts, and process validation support.
