Two of PCS’s tribology test equipment and laboratory instruments feature the IEF Werner Domiline linear motion system from Rodriguez.

PCS Instruments manufactures equipment for testing fuels and lubricants for oil companies, national standards laboratories and test houses.

When specifying components for its tribology test equipment and laboratory instruments, it needs to satisfy both performance and appearance criteria.

Formed by a group of research engineers from the Tribology Laboratory at Imperial College London, PCS uses computer control and measurement techniques, enabling automation, flexibility and low operating costs.

Its range of test equipment performs standard ISO, ASTM and CEC test procedures and other specialised research tasks.

The PCS Mini Traction Machine is a flexible general-purpose instrument for measuring the frictional properties of lubricated and unlubricated contacts under a range of rolling and sliding conditions.

One of the main applications is the fully automated traction mapping of lubricants under conditions commonly found in internal combustion engines.

Domiline is responsible for the linear motion and focus adjustment of the red-green-blue (RGB) colour camera and microscope system.

It plays a similar role in PCS’s EHL Ultra Thin Film Measurement System.

This is a computer-controlled instrument for measuring the film thickness and traction coefficient of lubricants.

The Domiline assembly specified for this product focuses a spectrometer and monochrome camera.

Dr Matt Smeeth from PCS said: ‘Standard, long-axes lengths available in single- and multi-axis combinations and the fine adjustment of 0.05mm were the main reasons for the choice of Domiline for these applications.’ Manufactured from hard anodised aluminium and with a stainless-steel option, the compact Domiline system offers high load ratings, low play and easy motor assembly, according to Rodriguez.

It is specified for X-Y-Z applications across a variety of sectors, ranging from adjusting soldering heads to measuring optical fibres.

Also available is a low-cost turntable for rotary motion, which can be fitted with a digital display for NC positioning.
