JONES & LAMSON TNC-621B HORIZONTAL MACHINING CENTER

Technical Description

The Jones & Lamson TNC-621B is a horizontal machining center designed for precision turning with robust capability. It features a single main spindle with a maximum turning diameter of 24.000 inches and a maximum turning length of 34.000 inches. The spindle accommodates a 15.000-inch diameter chuck and offers a maximum swing of 28.000 inches, supporting a bar capacity of up to 4.500 inches. The spindle is powered by a 50 HP motor with a maximum rotational speed of 1,200 RPM, ensuring adequate power for heavy-duty machining tasks. The machine employs two turret tool carriers: the primary turret holds up to 12 tools for both turning and rotary operations, while the secondary turret accommodates up to 6 tools. It supports the simultaneous use of 2 cutting tools, enhancing machining complexity and efficiency. Movement is controlled over four axes, with X-axis travel of 7.500 inches, Y-axis and Z-axis travels of up to 34.000 inches. The machine supports rapid and maximum feed rates of 400 inches per minute on the X, Y, and Z axes, enabling swift tool positioning and high-speed cutting performance. This combination of features makes the TNC-621B suitable for medium to large-sized parts requiring multi-axis horizontal turning with tooling flexibility and substantial machining envelope.
