Used NATIONAL OPTRONICS 3B #9316552 for sale

NATIONAL OPTRONICS 3B is a high-precision, three-axis, computer numerically controlled (CNC) machine tool, designed for the production of precise machined parts. The machine is composed of a hollow column spindle assembly, heavy cast iron base, three linear axis, and a tool changing equipment. With a direct drive spindle, 3B is designed for processing a wide variety of materials. The spindle has a maximum spindle speed range of 0 to 15,000 RPM and maximum torque of 20Nm. Control of the spindle is integrated into the programmable numerical control unit, ensuring seamless and dynamic spindle control. Spindle bearings and housing segments are permanently lubricated and thermally controlled to ensure precision machining of parts. In addition to the spindle, NATIONAL OPTRONICS 3B offers three large linear axes for machining of complex three dimensional shapes or engraving. The X, Y, and Z axes have a maximum travel distance of 300mm each and a rapid variable speed of up to 24m/min. The standard ballscrew drive and pre-loaded linear bearings ensure accuracy and repeatability of all machined parts. 3B also features an automatic tool changer system allowing for quick tool changes and improved process flexibility. The unit holds 30 tools with a maximum capacity of 2.5kg each, and features a high speed cycle time of 0.8sec for tool changes. For increased safety, the machine is equipped with an additional manual tool changer for the steepest of working surfaces. NATIONAL OPTRONICS 3B also offers several advanced features to ensure precision, repeatability, and rigidity. It features a built-in tapped hole recognition tool to ensure the accuracy of tapped holes. The machine also has an in-machine accuracy verification asset, which uses a laser-based metrology to ensure accuracy is maintained throughout the entire machining process. In addition, 3B is equipped with a thermal compensation model, which aids in optimizing the machine's accuracy and precision. NATIONAL OPTRONICS 3B is an industry-leading machine tool designed for precision machining and engraving of a variety of materials. With its direct driven spindle, precise linear axes, and integrated tool changer, 3B is the ideal solution for modern machine shops.
