The market for technical components made of steel, metal or ceramics is large, the precision industry
has a future, a research-intensive guild. This is because there are countless applications with increasingly
specific requirements, especially in medical, measurement and control technology. Or in automotive
engineering, for example, when sensors need to measure brake pressures or fuel flow.
Water pumps for the dishwasher at home need polished sliding seals, chemical pumps on an industrial
scale cannot exist without smooth ceramic rings, and plastic elements come from injection molds, which
of course in turn must have excellent surfaces. One must always fit into the other – ultra-precisely and
reproducibly. Each part is not installed until the surfaces are perfectly milled, ground, lapped and
polished. “Many can do the milling and grinding, but that’s not what we do,” explains Martin Spring,
Co-CEO of Pureon. “We take care of the lapping and polishing, and that is a real art!” There are few, but
crucial, things that someone who wants to master this art must bring to the table.
Let us go back to the starting point on the way to the optimum solution: Once all the specifications are
on the table – the type of workpiece, the desired roughness, the machine configuration at the customer’s
plant, the cleaning line and, above all, the desire to reduce the reject rate – then the analysis begins.
Either on site at the customer’s or in Lengwil, Switzerland, with the possibilities of test series also in
large format. The search is on for exactly the right diamond formulation for the problem in question.
Once a solution has been found, the question of rejects is also solved. Pureon manages to reduce the rate
“Our formulations are tailor-made. Above all, we bring one thing to the table: the ability to understand
the big picture,” explains the Co-CEO. Polishing is a matter of know-how from trained specialists with a
professional background as engineers, toolmakers, machining specialists or polymechanics. There is no
standstill, at Pureon there are regular trainings and education. Knowledge “state-of-the-art”, a lot of
experience, reliability and 100 percent quality control of the products counts also in another sub-segment
of the precision industry that Pureon serves.
