CITIZEN B12EVI HORIZONTAL MACHINING CENTER

Technical Description

The CITIZEN B12EVI Horizontal Machining Center is a high-precision CNC lathe designed for demanding small-part production. Featuring a single main spindle with a maximum turning diameter of 0.470" and a maximum turning length of 5.310", the machine delivers exceptional accuracy and repeatability. The main spindle achieves speeds up to 12,000 RPM, powered by a standard 2.0 HP motor with an optional 3.0 HP configuration for increased performance. The B12EVI is equipped with a back spindle, also capable of 12,000 RPM and 2.0 HP (optional 3.0 HP), enabling simultaneous front and back machining operations. The machine supports up to five axes of motion, including X, Y, and Z axes, with rapid traverse rates of 590 ipm on each axis, ensuring fast tool positioning and reduced cycle times. The X and Y axes each offer 1.000" of travel, while the Z axis provides 5.260" of travel, accommodating a wide range of part geometries. The B12EVI integrates a multi-axis control system with a fully electronic, full-servo design, eliminating belts, hydraulics, and pneumatics for reduced maintenance and downtime. The tool layout is flexible, supporting up to five turning tools, three live cross tools, and four front/back ID tools, allowing for complex part processing in a single setup. The machine’s compact footprint and advanced thermal displacement control ensure stable, high-precision machining even during extended operations.
