Touch Probes for Machine Tools
3-D touch probes from HEIDENHAIN were conceived for use on machine tools – in particular milling machines and machining centers. 3-D touch probes help to save costs: NC controls can automatically run setup, measuring and verification tasks – and most controls can also run them under program control.
The stylus of a TS three-dimensional touch trigger probe is deflected upon contact with a workpiece surface. This releases a trigger signal in the TS that is transmitted to the control either through a cable (TS 220 and TS 230) or as an infrared light signal (TS 7xx, TS 6xx, TS 4xx). The control simultaneously saves the actual position values as measured by the machine axis encoders, and uses this information for further processing.
Tool measurement on the machine shortens non-productive times, increases machining accuracy and reduces scrapping and reworking of machined parts. With the tactile TT touch probes and the contact-free TL laser systems, HEIDENHAIN offers two completely different possibilities for tool measurement.
