Heckert HEC 400 Machining Centres Rev Up For Automotive Users

Added to MTDCNC by Starrag UK Limited on 04 September 2015

The combination of power, precision and productivity – plus cost-effectiveness – has recently seen Starrag UK supply another batch of Heckert HEC horizontal machining centres to a UK-based major supplier of components to the automotive sector.



These four-axis machines are the latest tranche of HEC models that are being used throughout the automotive sector – by OEMs and their top-tier suppliers – for the single set-up machining of workpieces such as gearboxes, coupling housings and valve bodies, and they are proving especially effective when used as manufacturing cells/flexible manufacturing systems.



For example, a group of five HEC 400 D machines (plus one five-axis HEC 500 Athletic horizontal machining centre) are successfully being used in a flexible machining system for the production of four-cylinder aluminium and cast iron crankcases. The result is reduced machining and door-to-door times compared with the previous methods.



And a cell of eight HEC 400 D machines are processing flywheels – the machines’ guaranteed uptime of 95 per cent has led to a number of benefits, including reduced machining cycle times and less overall operating costs.



The 500 mm by 400 mm pallet HEC 400 D can be supplied in a variety of modes to suit specific needs:

[] For machining light alloys, cast metals and steels - with rapid traverse rates of 60 m/min and spindle speeds of 10,000 revs/min (optionally 20,000);

[] With Starrag’s Dynamic package - traverse rates up to 100 m/min and 15,000 revs/min spindle (optionally 20, 000 or 24,000 revs/min); and

[] With Power package for heavy-duty cutting - 37 kW main spindle/350 Nm torque plus 60 m/min traverse rates.



While such impressive traversing rates are courtesy of powerful AC feed drives in all linear axes - complemented by highly accurate profile rail guideways on all axes to guarantee a consistently high degree of positioning - the machine’s ability to minimise unproductive downtime is also ensured by chip-to-chip times of just 2.7-3 secs in conjunction with a 60- or 80-tool magazine. In addition, pallet change takes just 8 secs. There is an option for multiple chain magazines providing up to 320 tools.



The machine’s high-level performance is underpinned by Heckert’s renowned compact thermo-symmetric machine design techniques, which results in a machine that exhibits excellent damping and very low heat expansion.



Another design highlight is the machine’s ability to efficiently remove large amounts of chips, via a wider than usual chip conveyor, to minimise the likelihood of swarf build-up and heat problems, thus creating an ideal environment for dry machining.



The Heckert HEC range extends to HEC 500 machines with pallets of 500 mm by 630 mm and includes the five-axis HEC 500 D U5 model with NC swivel head.
