A training machine designed to raise the skill level of horizontal-machining-centre operators has been introduced by Heller Machine Tools Ltd (www.heller.biz).

Available for demonstration in the new customer area at the company’s Redditch factory, the latest CNC ProfiTrainer builds on the capabilities of an existing four-axis (rotary-table) version by offering the option of an additional +30/-120deg A axis.

Powered by a single-phase electrical supply, this machine is likely to be of interest to industrial training establishments, colleges and schools, particularly as it is small enough to be transported between different educational centres, if necessary.

Larger OEMs and sub-contractors may also choose to use it for operator training (there is a rental option, with payments subtracted from the purchase price, if a customer later opts to buy the machine).

Fitted to the machine’s ‘simulator’ is a full version of the Siemens 840D sl control, although Fanuc and Heidenhain equivalents can be specified, if preferred. Having 200mm travels and driven by servomotors at up to 15m/min, the machine is designed to mimic the operation of a full-size Heller machine tool.

The multi-functional spindle is new. Driven by a 9,000rev/min 2.75Nm motor, it offers the options of an ER16 collet as well as manual and automated inserts for holding HSK25 tools.

Heller’s latest CNC ProfiTrainer, which is designed to tolerate operating errors, provides skills training without tying up a machine on the shopfloor — and without the risk of a crash occurring on a real machine.
