Five-axis machine supports training

A training machine designed to raise the skill level of horizontal machining centre operators has been introduced by Heller Machine Tools. Available for demonstration in the new customer area at the company’s UK factory in Redditch, the latest CNC ProfiTrainer builds on the capabilities of an existing four-axis (rotary table) version by offering the option of an additional +30/-120° A axis.

The machine, which is powered by a single-phase electrical supply, is likely to be of interest to industrial training establishments, colleges and schools, especially as it is small enough to be transported between different educational centres if necessary. Larger OEMs and subcontractors may also choose to adopt the machine 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 200 mm travels driven by servomotors at up to 15 m/min over linear rails, the machine is designed to mimic the operation of a full-size Heller machine tool.
The multi-functional spindle is new. Driven by a 9000 rpm, 2.75 Nm motor, the spindle 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 shop floor. With this in mind, the risk of a crash occurring on a real machine is eliminated.
