The Altaira is designed to satisfy high-production OD grinding applications on work parts with diameters ranging to 16", with an overall length ranging to 40" and as heavy as 600 lbs.  

The grinder’s high-speed spindle capability and the inherent stiffness are suited for high speed CBN peel-grinding applications. The single-pass profiling peel process allows the user to grind a variety of shapes on any number of part configurations, all with the same grinding wheel.

Overall floor space is kept to a minimum through the use of a compound linear-slide design. The X-axis, in-feed slide is mounted directly above the Z-axis cross slide. The work part is placed between centers on a fixed tooling plate providing maximum stiffness and improved accuracy.

The grinder features a shear-damper machine base; cross-roller linear ways; GE Fanuc 18iTB CNC control; variable speed wheel drive; Trabon automatic lubrication; Z-axis, linear motor drive; X-axis, low-inertia break-away coupling; live spindle workhead; hydraulic tailstock; and a full enclosure.

The grinder can readily be automated. Both hard-tooled gantry systems and flexible Fanuc robotic systems are offered to suit an end-user’s specific application.

When Grinding Is Like Turning

This shop leverages a high-speed peel-grinding process that resembles turning to effectively grind challenging materials such as carbide. Inherently low grinding forces mean high material-removal rates are possible.
