JONES & LAMSON TNC-4521B HORIZONTAL MACHINING CENTER

Technical Description

The Jones & Lamson TNC-4521B is a horizontal CNC machining center designed for precision turning and multi-axis operations. This machine features a single main spindle with a maximum turning diameter of 24.000 inches and a maximum turning length of 34.000 inches, accommodating bar stock up to 4.500 inches in diameter. The 15.000-inch chuck diameter provides secure workpiece holding during machining operations. The spindle operates at 1,600 RPM with 50 horsepower, delivering consistent cutting performance for production runs. The machine is equipped with dual turret tool carriers, the primary turret accommodating up to 12 tools for turning and rotary operations, while the secondary turret holds an additional 6 tools, enabling efficient tool changes and complex multi-operation sequences. With capability for 2 simultaneous cutting tools, the TNC-4521B can execute compound machining operations, significantly reducing cycle times. The machine incorporates 4 axes of controlled motion: the X-axis provides 7.500 inches of travel with maximum feed and rapid traverse rates of 400 inches per minute, while the Z-axis offers 34.000 inches of travel at matching 400 ipm feed and rapid rates. This configuration enables complex contouring, angular cuts, and intricate part geometries. The maximum swing of 28.000 inches accommodates larger workpiece diameters. This versatile machine is suitable for production work in automotive, aerospace, and general machining applications requiring precision and repeatability.
