PH20 system maintenance

CAUTION: Always adhere to the safety instructions given in this guide (General safety instructions). Failure to do so could adversely affect the performance of the PH20 system and / or lead to personal injury.

General

CAUTION: The PH20 head has no user serviceable parts. In the event of a problem, please contact your local supplier for assistance.

Following the simple maintenance procedures given below will prolong the operational life and continued high performance of the system. The user should determine the frequency of inspection and maintenance actions according to the conditions of use.

The external surfaces of all system components should only be cleaned using a soft, lint free cloth., all parts should be kept dry.

The probe kinematic coupling mechanisms have a precision ball seating and permanent magnets. It is recommended that all these features be cleaned before first use, and thereafter at regular intervals. The frequency of cleaning depends on the local environment conditions, but should be at least every 500 changes.

A cleaning kit is available from your local Renishaw supplier (Renishaw part number A-1085-0016) and comprises of strips of ‘yellow tack' material. For cleaning small diameter products such as TP20, it is recommended that the protecvie film is peeled back from the yellow tack, and the kinematic coupling face of the product is firmly pressed into the material.

Styli

Stylus balls, threads and mating faces should be cleaned using a proprietary cleaning cloth or solvent. Stylus balls should be regularly inspected for damage or ‘pick-up' of component material. See Styli and accessories - technical specifications guide (Renishaw part number H-1000-3200).
