AF 400 Precision and flexibility in con rod machining.

AF 400 Minimum non-productive times. Maximum production. Professional division of work tasks: The division of semi-finish machining and finish machining in the highly specialized machines AT 200 respective AF 400 allows the parallel machining of components. The fixtures can be optimized for the different requirements of semi-finish and finish machining, thus enabling a drastic increase of productivity and precision. In addition, this separation of machining operations provides for a simpler and clearer process sequences.

To be uncompromising means to create a customer-oriented concept leaving the limits of existing technologies behind. As a result, this uncompromising attitude is the foundation of a new, highly specialized and modular generation of con rod machines. High production volume. Consequent flexibility. Individual scalability. Low change-over times. Highest precision.

ROTARY INDEX TABLE ASSEMBLY MACHINE AX 400 The AX 400 for rough machining of con rods. The rotary index table assembly machine for fracture splitting and assembly of con rods. · Productive as a special purpose machine, flexible as a machining center. · Machining of up to 4 con rods simultaneously · Extremely short chip-to-chip time thanks to main time-parallel tool change · Main time-parallel loading and unloading of components · Loading robot integrated in machine control, thereby simple operation without any robot knowledge · Ergonomic loading station for quick and fool-proof tool change,...

The AT 200 for semi-finish machining of con rods. The AF 400 machine for finish machining of con rods. · Up to 4 fixtures can be mounted simultaneously for short change-over times · Up to 2 turret heads with each 4, 6 or 8 tools · Extremely short chip-to-chip time · No chip problems at the tool interface thanks to the use of the tool turret · High thermal stability · High operator convenience · Very good accessibility for maintenance and tool change · Low space requirement in floor space and height · Very versatile: as variant with Y-stroke 630 mm a highly productive and process-safe...

UNCOMPROMISINGLY SPECIALIZED The AT 200 and the AF 400 con rod machines are specialized in semi-finish and finish machining whereby every machine is optimally designed for the corresponding requirements. Highly precise sub-assemblies are only used where required. The division of work tasks to two machines provides for easier and clearer process sequences. PARALLEL MACHINING In a machine concept combining finish and semi-finish machining, the corresponding work steps can not be realized simultaneously at different stations. Therefore the ALFING solution allocates the machining process to two...

CLAMPING FIXTURE The clamping fixture swiveling around the A-axis linearly moves in Y-direction. UNCOMPROMISINGLY FLEXIBLE The clamping fixture swivels around the A-axis and can be moved linearly in Y-direction. It can be quickly changed over and allows a clamping sequence freely programmable in the NC program. Due to the high flexibility it offers the possibility to quickly, easily and cost-efficiently produce different component types on the machine. Thanks to the clamping tombstone concept, up to 4 different component types can be machined without any change-over. HYDRAULIC ROTARY...

UNCOMPROMISINGLY PRECISE All main spindles of the AF 400 are equipped with hydrostatic bearings and direct drives, preventing vibration problems occurring with usual belt drives. SPINDLE CONFIGURATION Crank and pin end are machined one after the other by displacing the Y-axis. Thus reactions of the two machining processes are avoided, and the bore pitch can be produced with full flexibility and utmost precision. Depending on the size of the con rods, up to 3 x 2 spindles with a pitch of 250 mm for truck con rods or up to 4 x 2 spindles with a pitch of 200 mm for passenger car con rods are...
