This Erwin Junker BUAJ 50 CNC cylindrical grinding machine is designed for centerless grinding applications and features a robust industrial build. The machine measures 4800 mm in length, 2800 mm in width, and 2300 mm in height, with a total weight of 149 kg. It accommodates workpieces up to 1300 mm in length and supports a maximum grinding wheel diameter of 500 mm.
The machine is equipped with a grinding spindle capable of handling grinding wheels up to 500 mm in diameter, suitable for various grinding tasks. The control system includes a Fanuc 0-GC controller, complemented by a control panel mounted on the right side of the machine, featuring a digital display, buttons, switches, dials, and indicator lights. The panel also shows coordinate readings and includes components from Marposs, indicating integrated measurement or control features.
The grinding machine operates on a 3x400V, 50 Hz power supply with a total machine power of 60 kVA and is protected by a 3 x 100 A fuse. The electric motor powering the grinding spindle delivers 22 kW, with the spindle capable of speeds ranging continuously from 23 to 291 rpm. The grinding wheel achieves a maximum peripheral speed of 45 m/s.
Additional features include a driving headstock with an MK 5 clamping cone and a spindle rotation angle of 90°. The machine is currently disconnected and requires manual startup before automatic operation can begin. The enclosure of the machine is white with a window panel, showing some signs of wear consistent with use but remains in good physical condition. The interior components, including the spindle, motor, and coolant nozzles, display typical usage wear such as paint wear and some dirt accumulation.
This machine is suitable for precision cylindrical grinding tasks and includes a comprehensive control interface for operational adjustments. Please note that the machine's CNC functionality is not confirmed, and the automatic start requires manual initiation as described.
