Machine tool for machining end faces of gearwheels has tool assembly swivelling about bearing point with swivel position adjusted by linear drive which engages on tool assembly at distance from bearing point

摘要

The machine tool has a rotary driven workpiece spindle (1) and a tool assembly (4) with rotary driven tool spindle (6). The tool assembly is able to swivel about a bearing point (P) and a linear drive (8) is provided engaging at a distance (A) from the bearing point on the tool assembly in order to adjust the swivel position. Two linear drives can be provided acting perpendicular to each other and engaging at a distance from the bearing point on the tool assembly. The bearing point is formed by a ball bearing point.
