Abstract
A honing machine includes a machine housing enclosing a workpiece spindle and a tool spindle. The workpiece spindle includes a spindle collar with a spindle head configured to hold a workpiece. The tool spindle includes a cup-shaped holder with a honing ring located on an inside of the cup shaped holder. An operating tank is also located within the machine housing, where the operating tank surrounds the tool spindle in an oil-tight manner. The operating tank includes a panel with a recess, where the workpiece spindle is configured to insert the spindle head through the recess and form a first oil-tight seal between the recess and the spindle collar. The panel is moveable relative to the operating tank and tool spindle when the panel is carried along by the workpiece spindle during a feed motion. A second oil-tight seal is formed between the panel and the operating tank.
