This Studer RHU 500 internal grinding machine features a center height of 125 mm and a distance between centers of 500 mm, making it suitable for precise internal grinding tasks. It is equipped with a grinding wheel diameter of 400 mm and a wheel bore measuring 127 mm. The machine offers six grinding wheel speeds, with a minimum rotation speed of 1500 rpm and a maximum spindle speed of 2420 rpm, allowing for versatile grinding operations. Workpiece speeds range from 25 rpm to 450 rpm, and the spindle bore is 25 mm. The table can rotate up to 12°, and the table speed ranges from 0.1 to 6.0 meters per minute, providing fine control over the grinding process.
The machine's overall dimensions are 1800 mm in length, 1300 mm in width, and 1600 mm in height, with a total weight of 2200 kg. It includes a CM5 spindle and a CM3 tailstock. The machine body is painted blue and features protective covers and a work table. Controls include a panel with three buttons (green, white, red) and two hand wheels for operational adjustments.
Visible hydraulic or coolant hoses are connected to the upper section, and there is an electrical control box mounted on the side with cables and hoses extending from it. A hydraulic or coolant reservoir and pump assembly are attached to the machine base.
Please note that the machine shows signs of wear and age, including visible rust, paint chipping, corrosion, stains, and discoloration on various metal surfaces such as the upper parts, side and rear panels, and base. The grinding wheel housing and surrounding areas also exhibit rust and residue buildup. The metal worktable shows signs of wear and staining. These condition aspects should be considered when evaluating this machine for purchase.
