EMO visitors will see Kern (Stand C21, Hall 1) undertake live machining demonstrations to show how injection moulding tools for filter housings (used in respiratory masks) can be machined with a precision of less than 1 µm and surfaces in the single-digit nanometer range. This level of precision and surface finish will be demonstrated on the Kern Micro HD machining centre that is now available in the UK from Rainford Precision.

The parts will initially be roughed with the Heidenhain optimised contouring machining (OCM) option and then brought to the highest quality at critical points with five-axis jig grinding cycles. After machining, the manual polishing of such precision parts is an industry-standard process, however, as the Micro HD achieves surface quality in the single-digit nanometer range, manufacturers can omit this step.
