SCHAUMBURG, IL – With the new TS 249, HEIDENHAIN offers an extremely compact touch probe primarily for use in NC-controlled grinding machines and lathes. This small device provides immediate connection to all common control types.

NC-controlled cylindrical and tool grinding machines are often equipped with a touch probe mounted on a tilting fixture in the machine workspace when there are tight workpiece tolerances to meet and the high process reliability required. On surface grinders, it is common to see them used for in-process measurement — for example on workpieces with very long dimensions — to ensure optimum process control. On lathes, touch probes are commonly used when demanding workpieces have to be measured in small batch production. A touch probe can also be used to inspect turning tools for wear and breakage directly in the machine.

In-process measurement requires a touch probe with high repeatability and a high number of probing cycles. The HEIDENHAIN TS 249 meets these demands with its exceptional signal quality and high trigger-point repeatability. And because the sensor operates without wear, accuracy is ensured for a large number of measurements over a long period of time.

The TS 249 touch probe also provides trigger signals that are ready for immediate processing by the controls. There is no need for an amplifier interface between the device and the control. In addition to the standard HTL signal, the TS 249 provides a floating trigger signal which is required primarily for connection to FANUC controls. Transmission is immediate when incorporated with all HEIDENHAIN controls.

The TS 249 touch probe is available as standard with axial cable outlet. A variant is available with radial cable outlet, if required.
