Original Press Release:

Heidenhain's New Compact Infrared 3-D Touch Probe - The TS 440

SCHAUMBURG, IL - (July 2004) - The newest addition to HEIDENHAIN's recently improved 3-D touch trigger probes is their compact TS 440 model. Its extremely small dimensions make the infrared TS 440 the ideal touch probe for machines that are carrying out repeated setup and inspection procedures and have limited working space.

The TS 440 is offered in as small a size as 0.49 mm x 63 mm, and offers 360 degrees transmission. Its features are similar to HEIDENHAIN's TS 640 Trigger Probe, and in conjunction with the HEIDENHAIN's transceivers, can be used on the iTNC 530 control and higher.

HEIDENHAIN also offers another new transceiver for the infrared touch probes, the SE 540. It is designed for installation in the headstock providing the advantage of moving along with the touch probe. This ensures a reliable transmission of infrared signals at any position of the machine's working space and is an advantage with very large machines and those whose spindles move in two separate working spaces.

3-D touch probes are ideal for quick and exact workpiece alignment as well as for automated workpiece measurement on the machine. Most CNC controls - especially the TNC controls from HEIDENHAIN - offer numerous measuring cycles to automatically measure and determine common geometries such as bore holes, rectangular pockets, circular pockets, slots, studs, bolt hole circles and planes.

For more information on the TS 440, contact HEIDENHAIN at (847) 490-1191 or HEIDENHAIN CORPORATION, 333 E. State Parkway, Schaumburg, IL 60173. HEIDENHAIN can also be accessed directly via the web site at or e-mail at
