Acceptance conditions for broaching machines of vertical internal type－Testing of accuracy

This document outlines the acceptance criteria and precision inspection methods specifically designed for vertical internal hole broaching machines. It establishes a standardized framework to verify the dimensional accuracy and geometric tolerances essential for the proper functioning of these specialized machine tools. The content details the necessary test conditions, including the configuration of workpieces, measurement instruments, and procedural steps required to assess the machine's performance against defined precision levels. It addresses critical aspects such as the alignment of the spindle, the flatness of the bed, and the positioning accuracy of the ram movement during operation. By providing clear guidelines on how to conduct these inspections, the standard ensures consistency in evaluating the quality and reliability of new or refurbished equipment. This approach facilitates uniformity in quality control processes across manufacturing facilities, allowing for reliable comparisons between different machines. The procedures described are intended to be applied by technical personnel responsible for machine validation, ensuring that the equipment meets the necessary specifications for precision machining tasks involving vertical internal broaching operations.
