Broaching and Broach Sharpening Machinery Catalog

Technical catalog from Machinery magazine (July 1936) detailing Colonial Broach Company's comprehensive range of broaching and broach-sharpening machinery. This workshop manual covers twelve fundamental types of broaching machines and broach-sharpening equipment representing approximately fifty different models across the company's full product line. Includes single-ram surface broaching machines with six to twenty-five ton capacities across eleven sizes, dual-ram surface broaching machines featuring receding tables for efficient operation, internal broaching machines for precision finishing, gear broaching machines for gear production, and keyway broaching presses available in one to four ton capacities for keyway and spline work. Dedicated sections cover specialized broach-sharpening equipment designed for both surface and cylindrical broach maintenance and tool restoration. Technical details emphasize hydraulic actuation systems, hardened steel ways for precision alignment, semi-steel rams for durability, large coolant capacity for extended operations, continuous-feed fixtures for production efficiency, and the adaptability of machines to accommodate different work sizes and job requirements. An essential reference for machine shops, tool rooms, and manufacturing facilities operating broaching equipment during the mid-twentieth century.
