EMO Milano 2021 How can components be machined with a precision of less than 1 µm?

Editor: Alexander Stark

Germany — How can components — e.g. injection molds for filter housings — be machined with a precision of less than 1 µm and surfaces in the low single-digit nanometer range? At EMO 2021 in Milan, Hall 1 Booth C21, Kern Microtechnik will be demonstrating live how this is done.

For the five-axis series production of components with process-reliable accuracies of less than 1 µm, Kern Microtechnik offers special precision machines.

At EMO 2021 in Milan, the company will be producing live injection moulding tools for filter housings that are used in respiratory protection masks. The components are first rough machined with the Heidenhain OCM option and then machined to the highest quality at neuralgic points with five-axis grinding cycles via coordinate grinding. Normally, manual polishing is the order of the day after machining. Due to the high surface qualities in the low single-digit nanometre range that the Micro HD achieves, this production step can be omitted.

Several innovative features are decisive for the performance of this technological spearhead from Kern. According to the manufacturer, in addition to linear direct drives, the unique micro gap hydrostatics and sophisticated temperature management are the main contributing factors.

Depending on the user's needs, different automation systems can be integrated. Which ones to use depends on the specific application. Therefore, Kern considers targeted, project-related consulting to be almost indispensable.

At the company's stand, experts will answer all questions about the Kern Micro HD and also about all other Kern machines such as the variably configurable Micro Vario and the Micro Pro, a process-stable solution for efficient component machining in a price-sensitive market segment.
