HEIDENHAIN TS 460

Workpiece touch probes with hybrid signal transmission via RF and infrared signals.

Available with collision protection and thermal decoupling.

ts460 

The TS 460 workpiece touch probes with wireless connection is the new generation of compact probes designed for machine tools with automatic tool changing. The hybrid RF and infrared signal transmission means that the probe can be used on very large machines and also in applications such as probing inside a cylinder where a conventional infrared probe would fail to operate.

The electrical interface permits direct connection to most CNC systems, including FANUC.

 

Collision Protection Option

ts460 collision protection

A mechanical adapter between the touch probe and taper shank serves as collision protection. The touch probe can tolerate light collisions of its housing against a fixture or workpiece. At the same time, an integrated switch deactivates the ready signal and the control stops the machine. This collision protection therefore functions only if the touch probe has been activated.

The undamaged touch probe is recalibrated (via the control’s calibration cycle) and you can continue working. The collision protection adapter does not cause any additional error, not even at high accelerations, e.g. during tool change

 

Thermal Decoupling

ts460 thermal protection

Furthermore, the collision protection adapter functions as a thermal decoupler. This protects the touch probe from being heated by the spindle.

If the spindle gets very warm due to machining, the touch probe can also warm up—particularly in measuring cycles of long duration. This can lead to inaccurate measurements. Thanks to its collision protection, the touch probe with thermal decoupling prevents heat from being conducted from the spindle to the touch probe.
