Conditions of acceptance for horizontal internal broaching machines－Testing of the accuracy

This document specifies the acceptance conditions and precision test procedures for horizontal boring machines equipped with internal pulling mechanisms. It outlines the methodologies for verifying the dimensional accuracy and geometric tolerances of key machine components during the initial evaluation phase. The content covers the definition of reference surfaces, measurement points, and the environmental requirements necessary for conducting reliable testing. Detailed instructions are provided for assessing the alignment of the spindle axis, the flatness of the table, and the repeatability of positioning under static and dynamic conditions. These guidelines ensure that the equipment meets the required performance benchmarks for industrial manufacturing applications. The text establishes a unified framework for manufacturers and users to evaluate machine capabilities consistently. By adhering to these specifications, operators can validate the precision of the machinery before it enters production use. The scope includes various operational checks designed to confirm compliance with established engineering standards for this specific class of machine tools.
