Nagel Precision Inc. has a developed a series of flexible stone superfinishers for finishing inner and outer bearing races. The machines are custom designed to meet customer specifications and can be equipped with either Siemens or controls. The ultra-light finishing stone holder is mounted directly onto a heavy-duty servo oscillator and can attain oscillating speeds of up to 45 Hz. The directly coupled servo part driver can reach speeds of up to 3,000 rpm. Additionally, multiple finishing heads can be mounted to achieve the user’s desired quality and output. The custom developed superabrasive stones supposedly enhance tool life and part quality.

The new machine reportedly allows users to change from one part type to another quickly, minimizing idle time during the machine cycle. The superfinishing heads are mounted on an X and Z servo axis for automatic positioning to accommodate part diameter and thickness change. The patent pending part drive system can reportedly handle a range of part diameters without any changeover. The new system includes several industry features designed to make the machine more flexible and productive.
