Beskrivelse
PHS-2 is designed to meet the arduous requirements of ‘body-in-white’ measurement, where fine angular position and long reach are needed.
The PHS-2 servo positioning head features continuous servo drive in two axes, enabling the probe configuration to be positioned at almost any angle.
The PHS-2 head is driven to approximately the required position and, when a probing point is taken, the axes of the head latch simultaneously with the axes of the CMM to give accurate measurements.
A range of different probes can be fitted and automatically exchanged. These include touch-trigger probes and third-party laser/optical measurement sensors.
Extra-long extensions allow the Renishaw trigger probes to reach normally inaccessible features.
The head is protected by a built-in electronic over torque that disengages the head and signals the machine to stop in the event of a collision.

Accessories
PHS-2 interface card
The PHS-2 head is controlled by the head interface card in the CMM controller. The card handles communications and conditions the signals between the head and the CMM controller. The PHS-2 interface card does not handle probing system signals.
Kinematic mount
A kinematic mount (KM1 or KM2) allows quick fixing of the head to the machine and a fast changeover to a PH10 PLUS system (utilising a PHA1 or PHA2).
KM1 features through-quill cabling.
KM2 allows for cabling to run outside the CMM quill.
ACR2 autochange rack
The ACR2 autochange system is an arm-changing system for the PHS-2 servo positioning head system. It allows probe extensions or probe adapter arms to be exchanged to suit the probing task required.
Arms are locked or unlocked from the head by motion of the machine itself. The head engages a rack port and the machine drives the port: up to unlock an arm, or down to lock it in position.
No power connections or signal connectors to the rack are necessary, making installation very simple.
The ACR2 is supplied as pairs of rack ports which are mounted onto a suitable fixture supplied by the OEM. The system is modular and any number of port pairs can be used anywhere on the CMM.
Extended warranty
For peace of mind a 3-year warranty is available for your new CMM products during the first 3 months from purchase. Contact your vendor.
