In the world of metalworking, precision starts before the cutting begins. GOST 14034-74 ("Centre Holes. Dimensions" / Отверстия центровые. Размеры ) is a foundational Soviet-era standard—still widely used across the CIS—that defines the standardized dimensions, forms, and technical requirements for centre holes in metal workpieces. These holes are crucial for locating and supporting shafts and components between centers on lathes and grinding machines. 1. Purpose of Centre Holes

Understanding and adhering to is essential for quality control in manufacturing environments that utilize lathes and precision machining. The standard defines several forms, each designed for
