We have worked hard to minimize the opportunities for human errors through the use of hydrostatics, increased stiffness, and frictionless linear encoder seals. The machine base is a polymer concrete-filled steel fabrication to eliminate vibration. In addition, the raised rear bearing rail configuration produces a bed stiffness 1.6x higher than conventional flatbed designs.

The main axis of the machine uses a stepped rail hydrostatic design, to provide minimal roll errors in the tool infeed direction. The result? Maximum repeatability and precision.

Oil temperature is maintained at 0.01˚C for both the hydrostatic axes and the oil shower to produce a highly controlled microclimate.

We use advanced 3D CAD techniques and FEA to ensure the Cranfield Precision EcoR 1664 delivers the precision and consistency you need for your optical film application. Furthermore, the EcoR 1664 works with both the Cranfield Precision CNC6400 and Delta Tau control systems.

The machine is designed for workpieces up to 410 mm diameter and 1,600 mm long, weighing up to 1,000 kg. It is typically used for machining copper rolls but can be used with a range of parts and sizes. Contact us to talk about your application.

The EcoR 1664 diamond roll turning machine is specifically engineered to machine high precision copper rolls for the production of high-quality optical film.

Cranfield Precision machines are renowed for precision, reliablity and repeatablity. The Cranfield Precision EcoR is equipped with exceptional stiffness and damping, high thermal stability, and single point diamond cutting tools, which makes it ideal for the optical film market.
