Heckert DBF 630

4-axis machining center

The DBF 630 / 800 enable complete machining in one clamping position, hence the name DBF (which stands for turning-drilling-milling in German) which has a decisive effect on the productivity of the overall production system. The working spindle of the DBF heads carries out all the machining on the tool that is attached. When turning is required on a clamped work piece, the rotating lathe tool can be radially shifted by ± 1.38 inch (servo-axis).

The HEC 630/800 Athletic machining centers are the base system concept. The DBF head enables complete machining with a consistent axial and radial run-out of 5-6 µm on the part. The imbalance of the valve plate is compensated by a counterweight, allowing turning speeds up to 1,200 rpm

Key benefits:

– High level of process integration with turning, drilling, and milling in a machining center with a single clamping position reduces investment costs and production system footprint
– Optimized cutting set-up for milling and drilling (up to 3,500 rpm) and 60.3 hp drive capacity
– Wide range of turning applications (external turning, face turning, interior face-turning, interior straight turning and relieving)
– High transferrable torque (1,254 lbf/ft) maximizes cutting performance (drilling up to 3.94 inch diameters)
– Intelligent tool management with adjustable chain or tower magazines, tool ID, tool breakage control and r.p.m. monitor
– Reduced set-up times through parallel work piece mounting and removal
– Expansion through palette linear storage
