Brakes and Clutches


Both braking and clutch systems require well machined and correctly coated surfaces to ensure best performance over time. Fluid retention, surface texture direction and bearing area are just a few of the functional characteristics that can easily and readily be quantified via non-contact 3D optical metrology.

Engines


The production of engine blocks to exacting industrial standards requires the use of accurate metrology. In automotive plants around the world, 3D optical profilometry is being used to measure items such as the grind pattern on engine valves, the texture inside engine cylinders, and the critical characteristics of fuel injectors.


Gears and Sprockets


Automatic pitting identification and detailed time studies of lubricant and corrosion inhibition of gears is being used extensively in the automotive industry to enhance fatigue strength and improve manufacturing QC. 3D optical microscopy provides rapid, gauge-capable metrology for functional surface parameters relating to the performance of gears, including surface roughness, interfacial area, and fluid retention.

Interior, Exterior, and Other Trim


Producing attractive yet durable trim pieces is a must for automotive and aerospace industries who cater to public passenger transportation. From defect detection in chrome-plated moldings, handles, and interior trim pieces to wear measurement of synthetic coverings and rubber components, 3D optical microscopes enable engineers to improve their manufacturing processes and select the most optimized materials possessing both the appropriate aesthetics and the durability demanded by the industry.


Lubricants and Additives


The selection of the best lubricant and understanding the mechanism by which it acts to separate surfaces in an automotive component is a complex process. Bruker’s 3D optical microscopes enable engineers to clearly document and trace changes over time in lubricant transportation, as well as characterize the influence of additives and corrosion prevention techniques.
