Process for finishing a ball valve seat for an injection valve of an internal combustion engine |
| abstract |
The invention relates to a method for finishing a valve seat (3) for ball valves, in particular for fuel injection valves in internal combustion engines. The workpiece (2) to be machined and a finishing tool are driven in rotation, the axes of rotation of the workpiece (2) and the finishing tool (5) being aligned at an angle of 1 to 10 ° to one another and the finishing tool (5) over the entire circumference of the to be machined inner surface of the workpiece (2). According to the workpiece surface to be machined is spherical. A finishing stone (5, 6) with a wear-resistant, preferably conical machining surface (9) is used as the finishing tool (5), a narrow sealing zone with a convex profile in longitudinal section being created in the spherical workpiece surface by partial material removal. |
