TS27R PROBE FUNCTIONS

• Setting tool lengths in Z.

• Setting rotating tools in X and Y for radius

offsets.

• Tool breakage detection.

The probe body is fully adjustable to enable the stylus

tip to be aligned with the machine's axes. The probe

mechanism is protected from hot chips and coolant

by an outer metal eyelid and inner flexible seal. The

base T bolt is clamped in a machine table T slot.

Styli

Disc styli Ø12.7 mm (Ø0.5 in), or square styli

19.05 mm × 19.05 mm (0.75 in × 0.75 in) are

available. The stylus mounting allows styli to be

changed.

A weak link break stem protection device is

incorporated in the stylus mounting to protect the

probe mechanism from damage in the event of

excessive stylus overtravel or a collision. A captive

link secures the stylus to the probe if the break stem

is broken in the event of excessive stylus overtravel.

Achievable set-up tolerances

The achievable tolerance setting of tools depends

upon the flatness and parallelism of the stylus tip

setting. A value of 5 μm front to back and side to side

is easily achievable over the flat portion of the stylus

tip (5 μm parallelism with the axes of square tip styli is

sufficient for the majority of tool setting applications).
