The rigid, one-piece bed design of the next-generation UltraGrind CNC cylindrical grinding machine from Jones & Shipman provides stability and high stock removal rates while maintaining high precision, the company says. The mechanical, electrical and software features are said to ensure easy operation and change-over in demanding production environments. It is designed for precision production as well as high-volume environments for the aerospace, automotive and biomedical industries. The machine is also suited F1 and motorsport engineering, among other applications.

The modular wheelhead design provides a choice of external and internal grinding spindle combinations, with the maximum wheel size having a diameter of 500 mm and a width of 100 mm. The wheel spindle power ranges to 15 kW, increasing metal removal rates and productivity.

Angular wheelhead positional accuracy and repeatability are ensured via a high precision, 1-degree Hirth coupling. An optional B axis, programmable to 0.001 degree, utilizes feedback from a high-accuracy encoder mounted directly to the rotational spindle axis. The machine currently offers 650 or 1,000 mm between centers (with larger machine length capacities planned) and center heights of 180, 200 and 250 mm. The large diameter capacity can accommodate larger-mass components weighing as much as 450 Kg, and odd shaped components, which can result in high rotational inertia.
