 Precitech's solution for Freeform Head-up Display (HUD)
 Mold Manufacturing

If you are looking to manufacture Head-up Display molds for automotive or aerospace applications, the Nanoform® 700 ultra or Nanoform® L 1000, are uniquely positioned to meet your needs. When equipped with an HD-160 spindle with a C axis and Adaptive Control Technology (ACT) there is no better solution on the market today.

Link to an interview with Ralf Dupont, President at Levicron GmbH, as he talks to AZoM.com about how Levicron’s air bearing spindles are bridging the gap between conventional machining and ultra-precision machining.
Precitech along with other AMETEK businesses including TMC and Zygo recently exhibited at the Laser World of Photonics China in Shanghai. On display in our booth was the Nanoform X and Levicron air bearing milling and grinding spindle both from our Shanghai demo lab. Precitech’s local team of sales, applications, and service engineers were on hand to demonstrate the productivity and ease of use features of the Nanoform X including our oil hydrostatic rotary (B) axis and also the HSK quick change tool holders from Levicron. This generated a lot of interest and activity in our booth throughout the week.
