Vision Engineering, a specialist in microscopy, digital 3D visualisation and metrology solutions, has bought a third fixed-head lathe, an Italian-built Biglia B620YS, for its production facility in Send, near Woking. Supplied by UK and Ireland sales agent Whitehouse Machine Tools, the machine is turning a range of aluminium components for the top-quality objectives in Vision Engineering’s third generation of Mantis eyepiece-less 3D inspection microscopes, launched at the beginning of June 2023.

The company based its choice of turning centre on a set of specific requirements. There is no milling content in any of the cycles, so only turning tools are required and a single tool turret was therefore sufficient. Excellent turned surface finish is essential so that no marks are visible after component anodising, as good cosmetic appearance is important for customer acceptance.

Dimensional accuracy is also key to ensure perfect perpendicularity for precise lens placement and to facilitate cleanroom assembly, bearing in mind that anodising deposits a layer of variable thickness that uses up some of the drawing tolerance. Additionally, Vision Engineering neededa short lead timeso it could ship Mantis 3rd Gen stereo microscopes to its worldwide distributors in time for launch, as well as to maintain production momentum in the immediate aftermath.

Machine shop manager Scott Blackwell says: “The Biglia lathe was available ex-stock from the Whitehouse showroom. This was an advantage due to the large production volumes required across the range of aluminium objectives for our latest microscopes. The Biglia installation has turned out well. It’s a real workhorse; the turned parts it produces are impeccable and the unmanned running has proved to be very consistent.”
