TS 249

October 01, 2010

Heidenhain Corp. offers a compact touch probe primarily for use in NC-controlled grinding machines and lathes. This small device is based on the compay's sensor technology, providing 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 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 of the company's controls. The TS 249 touch probe is available as standard with axial cable outlet. A variant is available with radial cable outlet, if required.

  • fixture


    Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • process control

    process control

    Method of monitoring a process. Relates to electronic hardware and instrumentation used in automated process control. See in-process gaging, inspection; SPC, statistical process control.

  • turning


    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
