JOHNFORD - ROUNDTOP MACHINERY COMPANY QT-25H HORIZONTAL MACHINING CENTER

Technical Description

The JOHNFORD - ROUNDTOP QT-25H Horizontal Machining Center features a main spindle with a maximum turning diameter of 12.600 inches and a turning length of 29.920 inches, equipped with a 10.000-inch diameter chuck and a maximum swing of 26.770 inches. It supports bar diameters up to 3.050 inches. The machine includes a single main spindle operating at up to 3,500 RPM with a 20 HP motor. The primary tool carrier is a turret accommodating up to 12 turning tools and 12 rotary tools, each rotary tool powered by a 5 HP motor capable of 4,000 RPM. It provides simultaneous operation of one cutting tool. The machining center operates on two axes, with an X-axis travel of 7.800 inches and a Z-axis travel of 20.800 inches, both having rapid traverse rates of 787 inches per minute, ensuring fast and precise positioning. This configuration is optimized for high-precision turning tasks with moderate capacity, combining operational flexibility with solid spindle power for various metalworking applications. The turret design and tool capacity enable effective multi-tool machining setups, while the rapid traverse speeds allow for quick cycle times and increased throughput. Overall, the QT-25H provides a robust platform for small to medium-sized workpieces requiring precision horizontal machining.
