The Bahmüller IPE 12 i.S. is a CNC-controlled internal thread grinding machine designed primarily for ball screw spindle nuts. Manufactured in 1958, this machine weighs approximately 4500 kg and features a spindle power of 4.5 kW. It offers a maximum longitudinal travel of 250 mm and a cross travel of 450 mm, with a maximum height from spindle to table of 300 mm.
The machine is equipped with a Siemens SIECOMP control system featuring soft keys and a monitor, supporting 3-axis control with Siemens motors and Heidenhain scales on the X, Z, and C axes. All movements, leads, and infeeds are generated by this control system, enhancing precision and automation.
Key features include a mounted diamond roll profiling device by KW, which is swivable ±10° and is used to prepare the ball screw profile into the grinding tool. This device includes a hydraulic motor for tool speed control and a hydraulically movable tool holder arm for profiling procedures. The grinding spindle is a Fischer HF internal spindle capable of speeds up to 30,000 rpm, with oil and air lubrication and infinitely variable speed control. The spindle diameter is 120 mm, and it can be moved horizontally by approximately 100 mm and swivelled ±10°.
A built-on Forkhardt 4-jaw chuck with an approximate diameter of 250 mm is included, featuring internal coolant supply through the spindle. The workpiece head can be manually displaced on the table for about 400 mm along the Z-axis. Additional components include separate switch and control cabinets, a hydraulic aggregate, and a lubrication device.
The grinding area is enclosed with a hood and sliding door, and includes a cabinoil drip pan for cleanliness and safety. The machine exterior shows minor wear and some paint scratches consistent with typical industrial use. The visible chuck and grinding wheel spindle assemblies are installed inside the enclosure, supporting its intended grinding operations.
Overall, this Bahmüller IPE 12 i.S. machine offers robust capabilities for internal thread grinding with advanced CNC control and specialized accessories, suitable for precision manufacturing environments.
