This Studer RHU 400 cylindrical grinding machine is designed for precision grinding with a maximum workpiece length of 400 mm and a center height of 125 mm. It accommodates workpieces weighing up to 80 kg between centers, making it suitable for a variety of medium-sized grinding tasks. The machine operates without CNC control, relying on manual adjustments and controls.
The grinding wheel measures 400 mm in diameter, 50 mm in width, and has a bore size of 127 mm. It offers three speed steps ranging from 1500 to 1800 rpm, allowing for adaptable grinding conditions. The machine is equipped with an external grinding wheel motor rated at 3 kW, providing sufficient power for consistent grinding performance.
The workpiece spindle head features stepless speed control from 30 to 675 rpm and can be rotated 90 degrees. It includes a spindle taper of 5 MT, and the tailstock taper is 3 MT, facilitating secure and versatile workpiece mounting. The table speed is also steplessly adjustable between 0.05 and 5.50 meters per minute, enhancing control over the grinding process. Additionally, the machine allows angular displacement of ±45 degrees, increasing its flexibility for various grinding angles.
Visually, the machine includes two large control dials and a control panel with multiple knobs and buttons located at the front, enabling precise manual operation. An electric motor is mounted on top of the machine, and a hydraulic or coolant unit with motor and hoses is present, supporting cooling during operation. There are two grinding wheels or similar circular components stored on top of this unit. The machine and its associated units show signs of surface wear, paint chipping, and some dirt, indicating prior use and typical operational wear. The presence of an adjustable tool post and clamping mechanism further supports versatile setup options.
Overall, this Studer RHU 400 is a robust, manually operated cylindrical grinding machine suitable for various industrial grinding applications where CNC control is not required. Its comprehensive speed controls, adjustable components, and supportive coolant system make it a practical choice for precision grinding tasks.
