Synthetically Modeling of Thermal Error and Grinding Force Induced .

Abstract. Thermal errors and force-induced errors are two most significant sources of the NC grinding machine inaccuracy. And error compensation technique is an effective way to improve the manufacturing accuracy of the NC machine tools. Effective compensation relies on an accurate error model that can predict the.

Grinding Wheel Use & Precautions Safe Handling and Preventing .

Grinding wheels should be stored in a dry area in rooms not subject to extremely temperature changes. Thin wheels, such as those used for cutting off, should be laid flat on a flat structure of steel or similarly rigid material away from excessive heat, moisture, and other liquids to prevent warpage. Particular caution is required.
