PHS1 legacy probe head

  • PHS1 servo motorised headMeets the demanding requirements of "body in white" measurement where fine angular positioning and long reach are needed
  • 2-axis servo operated with a ±184° variable positioning capability in both axes
  • Long reach up to 750 mm (29.53 in) enables trigger probes to measure otherwise inaccessible features
  • Automatic probe changing
  • Repeatable exchange of PHS1 probe heads via KM1 / KM2
  • Easy interchange with Renishaw's PH10T PLUS / PH10M PLUS motorised heads via a PHA1 or PHA2 probe head adaptor in applications where existing parts need to be inspected without the need to re-write the programs for PHS1

System components

PHS1 head

This is not locked into position in the same manner as an indexing head. Instead, it 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 probe readings.

The PHS1 head is controlled directly via a PC interface card in the CMM controller, and requires full integration by the equipment supplier. It has an in-built overtravel protection unit that can be configured to stop the machine in the event of a collision.

An air supply to the head is recommended for axis motor cooling and optimum metrology performance.

    The Renishaw servo positioning head (PHS1) is a 2-axis motorised head with continuous 360° servo drive enabling the probe confi guration to be positioned at almost any angle. This makes the head ideal for use in restricted spaces and enables styli to be angled normal to a surface or aligned to the axis of a hole.

    The PHS1 head has been equipped with a head temperature sensing facility to allow thermal compensation. Previously, the PC card was unable to read this information but a new card has been designed to accommodate this facility.
