In June 2007, HEIDENHAIN shipped its 200,000th NC control.

According to Heidenhain's press release, with over 30,000 units, the current iTNC 530 has succeeded the TNC 426 as HEIDENHAIN's most successful of over 50 models. Over 10,000 units of this model are expected to ship from Traunreut, Germany in 2007.

These NC controls feature user-friendly dialog guidance in applications that require shop-floor programming. Heidenhain controls guide the user with questions and prompts and automatically generates the program. Since 2004, the "smart.NC" operating mode has offered straightforward fillable forms, interactive graphics and user aids.

Heidenhain controls are widely used on machining centers and complex milling machine for five-axis machining as the iTNC 530 stands for short machining times, high contour accuracy, short block processing times and optimal path control. In the mid-range, the TNC 320 provides precision in manufacturing on machines with up to four controlled axes. The TNC 124, a straight-cut control for simple machine tools, is designed for less demanding control tasks. Controls for lathes such as the MANUALplus 4110 complete the product range.
