Riten Industries, Inc. (Washington Court House, OH) developed Extra-Light live centers specifically to turn or grind parts weighing as little as two ounces. According to the company, these parts are often too flimsy to turn the larger bearings found in typical live centers, resulting in galling or excessive wear on the tip of the live center. The Extra-Light can turn parts at speeds up to 8,000 RPM while holding concentricity of ±0.00005. The small bearing head diameter and long spindle provide better clearance for small work pieces.
