“Nobody buys a black box from us,” says Willers. The customer first gives his specifications, which are
usually quite narrow; after all, he knows his components. Then various diamond grit sizes are tested,
results are analyzed, another parameter is changed, and a new test is started – until everything is quite
perfect. After all, we are talking about sensitive requirements in the value chain all the way to the end
customer. For this reason, new release samples are always created for each new application. Nothing is
left to chance. Pureon not only has a comprehensive range of diamond micrograins with precise
classification, but also compiles new diamond powders from different syntheses according to customer
needs. And the Swiss from Lake Constance have yet another plus to offer:
Because process repeatability is so important to customers, Pureon maintains inventory levels at all
locations – bucking the trend in logistics. “We don’t discuss things at length, but respond to our
customers’ wishes,” Willers reports. And they are happy to have access to proven quality products at any
time. This also applies to the tool industry, which Pureon supplies. The quality requirements for polishing
and grinding instruments used in the electronics, dental or jewelry industries cannot be set high enough.
Just think of precision grinding wheels for processing semiconductors. “Here, customers are looking for
ultra-precise grit sizes,” explains Helge Willers.
The market is large, and the major players are mainly based in Japan. What is important to them?
Maximum removal rates through a rough particle surface and the right classification, the highest purity
of the diamond powders and suspensions or liquid diamond supplied, short processing times and
first-class surface results. In other words, maximum quality.
