The stylus length is limited to 60 mm

The TP20 push button modules are relatively expensive at around € 890 / module

The service life of the modules is around 3 million. Touch points relatively low

Operation area:

If the probe head does not need to be rotated and swiveled too often and probe lengths of up to 60 mm are sufficient

Suitable for the following applications:

Swivel steps of 15 ° are sufficient

The duration of the measurement is not critical

The immersion depth of 60 mm is sufficient

More commonly used for small CNC measuring machines

Button pans are not that common

The Renishaw PH20 probe head in simultaneous panning

Renishaw PH20 swivel probe head

Renishaw PH20 5-axis probe head

PH20 5-axis probe head swivels to any angle in space

Can control any angle in the room. The resolution of the angular positions is 0.15 sec. When measuring circles, the head-touch function can be used. This means that the probing speed is up to 5 times higher than with conventional machine movements.

Benefits:

Any angle in the room can be controlled

The head-touch function can be used when measuring circles. As a result, the speed of probing is up to 5 times higher than with conventional machine movements

The probe head can be swiveled simultaneously with the machine movement

Small swivel radius

Compact design

Disadvantage:

The stylus length is limited to 60 mm

If the stylus is long, the head-touch speed and the scanning accuracy are reduced

The head-touch function can only be used to a limited extent in the X-Y plane

Operation area:

Ideally suited for workpieces with bores in any spatial angle

Preferred for measuring bores, as this is where the head-touch function can best be used

Suitable for the following applications:

The highest precision to be measured is approx. 0.014 mm

A short measurement time is important

An immersion depth of 60 mm is sufficient

Any angle must be able to be set, since many inclined holes have to be measured
