J&M TN400 CNC LATHE

Technical Description

This CNC turning center features a robust design engineered for medium-duty production applications. The machine accommodates bar stock up to 3.15 inches in diameter, making it suitable for processing solid round materials efficiently through automatic bar feeding systems. With a swing diameter of 15.75 inches over the bed, the lathe can machine workpieces up to approximately 7.875 inches in radius, providing adequate capacity for a diverse range of component sizes. The machine is equipped with advanced CNC control technology, enabling precise, repeatable machining operations with minimal operator intervention. This computerized control system manages all axis movements, spindle speed variations, and tool changes, facilitating complex multi-axis turning operations and high-precision finishing work. The turning center typically incorporates a live tool turret configuration with multiple tool stations, allowing rapid tool indexing and reducing setup times between operations. This design enables simultaneous turning and milling capabilities, enhancing manufacturing flexibility. Precision ball screws and linear guides ensure positional accuracy and repeatability, essential for maintaining tight tolerances on machined components. Common specifications for machines in this category include spindle speeds ranging from 0 to 6000 RPM, accommodating both finishing and rough cutting operations. The integrated CNC control system, such as GSK or Fanuc controllers, provides user-friendly programming interfaces and network connectivity for modern manufacturing environments. This machine class serves well for producing spindles, standoffs, turbine components, and other precision-turned parts requiring consistent quality and efficient production rates.
