HEIDENHAIN Introduces Infrared Touch Probe for CNCs

With the introduction of the TT 449 tool touch probe, HEIDENHAIN brings to market its first infrared tool probe.  Designed for use with numerically controlled machine tools, the TT 449 is suitable for applications where unlimited movements are necessary, such as with tilting or rotating work or rotary tables or with 5-axis machining centers.  It will be on display for the first time in North America at the International Manufacturing Technology Show (IMTS) at HEIDENHAIN’s booth # E-5131 (September 13-18) in Chicago’s McCormick Place.

Without the need for a cable, this new versatile infrared touch probe offers increased mobility.  For tool measurement and inspection right on the machine, it is a simpler alternative than the use of complex laser measurement systems seen commonly on 5-axis machines.

A key benefit of this wireless infrared touch probe is that the unit can be placed anywhere on a work table.  It is also possible for an operator to move and re-mount without the need to handle cabling.  Once mounted and put into operation, the disk-shaped contact of the TT is deflected and the signals are transmitted to the control over an infrared light beam.  The generated trigger signal is then transmitted via an SE 642 transmitter/receiver unit to the control, where it is further processed. The SE 642 can also be used for a spindle probe. The control then ultimately saves the measured tool length and radius in the tool memory.

The HEIDENHAIN TT 449 tool touch probe has protection of IP 67 and boasts continues duty at typically 200 hours with a lithium battery (included).  A battery warning is sent if its capacity falls below 10%, and a rated break point protects the touch probe from damage due to operator error.
