Heidenhain Offers New High-Precision Touch Probe for Grinders, Lathes

Offering many benefits, the new TS 750 high-precision touch probe is now available for in-process workpiece measurement in grinding machines and lathes.

Posted: June 6, 2021

Heidenhain's new probe is very durable and offers the ability to state the reproducibility of its jobs at increased probing speeds better than its competitors.

When working with soft or delicate workpieces, the TS 750’s low probing force is an important benefit. Its probing forces are approximately 1.5 N (axial) and 0.2 N (radial). So, the TS 750 can attain high probing accuracy (±1 µm) and repeatability with almost no effect on the measured object. Only on further deflection do the forces of the springs take effect until the machine stops.

The TS 750 operates with high-precision pressure sensors, with force analysis for generating the trigger pulse. The forces that arise during probing are processed electronically. This method delivers extremely homogeneous, 360° probing accuracy.  It offers high probing speed of up to 1 m/min and does not require a minimum speed.

Delivering reliable measurements after prolonged use–even after five million probing cycles–the TS 750 touch probe is still highly accurate: with a probing repeatability of down to 2 σ ≤ 0.25 µm at its high probing speed.

Johannes Heidenhain GmbH (Traunreut, Germany) develops motion control feedback solutions for many markets, including these: machine tool, metrology, and automation. Its North American subsidiary is Heidenhain Corp. (Schaumburg, IL, and San Jose, CA).
