The machine is designed specifically for high speed, high precision grinding of internal diameters.

The Landis-Bryant RU2 multi-surface grinder from Fives Landis Corporation (Hagerstown, MD) is an internal high speed production grinder that ideal for processing bores, faces and contours of bearing rings, valve lifters, gears, universal joint cups and CVJ components, and especially suitable for machining workpieces with an external diameter of up to 177 mm. The Landis-Bryant UL2 has been designed specifically for high speed, high precision grinding of internal diameters. With this single purpose firmly established, performance compromises have been eliminated. The machine’s unique torque tube bed design, combined with a “flow-thru” system that circulates oil and coolant through the base, provides ultimate rigidity and outstanding thermal stability to the machine’s grinding system.

Independent slides in X and Z, each mounted directly to the machine bed, make for an extreme low center of gravity. The machine’s round-bar hydrostatic slide ways in each axis provide an extremely stiff system with minimum friction. High resolution servo motors are directly coupled to super precision ballscrews for precise and reliable positioning throughout the entire production cycle. Whether the application calls for a diaphragm or collet chuck, a shoe centerless magnetic chuck setup, or a disc drive roll centerless arrangement, the Landis-Bryant UL2 allows for various machine configurations. This machine also offers automatic workpiece loading solutions for many applications, as well as In- and Post-process gauging in a very compact setup. Other features of the Landis-Bryant UL2 grinder include acoustic emission monitoring system (AEMS), automatic taper adjustment, Fanuc i Series as well as various dressing options.

This ID grinding system uses a precision spindle with infinitely variable speeds up to 120,000 rpm. It contains super-precision bearings that permit operation at extremely high speeds. It is powered by in-house-designed induction motors to provide superior performance for efficient machining.
