This is one of a range of machining centres built by Kern to achieve more exacting standards and achieve consistent, accurate, repeatable results with excellent finishes.
This is achieved in several ways, one of the key ones being the use of hydrostatics lead screws normally found in sophisticated grinding equipment to avoid the backlash associated with ballscrews. Probing of both the tools and the workpiece enables monitoring of all aspects and a 42,000rpm spindle takes surface finishing to a new level.
These machines are used in specific industries like watch making and optics, but allow us here at WLR to take a wide range of components to tighter and more repeatable tolerances – no need to ask for top or bottom limit!
These include parts for accurate metering systems, camera lenses, microwave, analytical & laboratory equipment, oil & gas applications, and many more.
