Used STAR JNC 25 #9091518 for sale

STAR JNC 25 is a machine tool manufactured by the Japanese company, STAR Machine Tool Corporation. It is a multi-function sophisticated machine tool which provides high accuracy and speed production capabilities in a small package. JNC 25 is capable of drilling, milling, tapping, and boring, and is most commonly used for precision machining operations. The core of STAR JNC 25 is its heavily reinforced, rigid structure which features an enhanced bed to facilitate heavier machining operations and improved axis positioning accuracy. It has a spindle speed of 8,000 RPM and can make precise cuts in steel of up to 25mm diameter. The machine is dynamic with a 30kW spindle drive motor which can execute precision machining operations at higher speeds with higher accuracy. In addition to the spindle drive motor, JNC 25 also boasts a high-accuracy ball screw with an increased pitch comprising a shell structure, linear encoders and chain-driven double nuts. This ensures superior cutting stability and minimal vibration, enabling the machine to maintain its accuracy for a much longer duration compared to traditional machine tools. STAR JNC 25 boasts a NC controller compatible with industrial Ethernet protocols, as well as electronic handwheels with built-in MPG (manual pulse generator) and operator panel. This provides stability and responsiveness when controlling the machines in both manual and automated operations and ensures a much shorter setup time and smoother operation than traditional CNC machines. The machine features an 8000mm/min rapid traverse speed and a conventional feed of 4000mm/min and optional 5000mm/min. Not only that, but JNC 25 is equipped with a M-code function, meaning that commands can be sent from a CAD system to the CNC controller, providing quick and error-free programming. Overall, the precision, speed and stability offered by STAR JNC 25 makes it an excellent choice for machine shops looking for reliable and continuous production-level machining capabilities.
