- crankshaft must meet high dimensional tolerance requirements.
- the bearing points are also closely tolerated in terms of their size and location in the cylinder crankcase.
- the relatively tight tolerances of the relevant parts of an internal combustion engine and a cylinder crankcase result from the complex functions of these parts.
- the shape, the dimensions and the surface topography of the cylinder bore determine the wear, the friction, the oil consumption and the emission values of the combustion engine as well as, as a consequence of the friction, the performance and the efficiency.
- the compressed combustion chamber volume primarily determines the compression of the engine. This has an impact on the performance and, through the combustion process, also has an influence on the emission values and engine noise.
- crankshaft The exact position of the crankshaft relative to the pistons or the cylinder bores is important, among other things, to reduce wear on the highly stressed engine parts. These are, in particular, pistons / piston pins, connecting rods and the bearing of the connecting rod on the crankshaft, as well as the bearing of the crankshaft in the cylinder crankcase. When it comes to the position of the bore axis, not only does the absolute position in space play a role, but also its angular position or orientation Role.

- Another work station is a horizontal honing station, which has at least one horizontal honing unit.
- the horizontal honing unit has a honing spindle with a honing tool.
- the honing of a bore aligned in the horizontal direction takes place by means of a relative movement between the workpiece and the honing spindle or honing tool that rotates about a horizontal spindle axis and translates along the horizontal spindle axis.

- FIG. 3 shows a plan view of a further exemplary embodiment of a honing machine 10 according to the invention.
- four work stations are shown, which are formed by four workpieces 12, analogously to the previous one
- the horizontal honing unit 26 is arranged on the machine base 14 in such a way that the horizontal spindle axis 30 does not run through the rotary table axis 20. Accordingly, the workpiece 12 must be aligned along this horizontal spindle axis 30 with its bore aligned along the horizontal direction. This is done by means of a rotation device not shown in further detail.
- the horizontal honing unit 26 is designed to be movable by means of rails, so that the horizontal honing unit 26 and thus also the honing spindle 28 with a honing tool can move back and forth along the horizontal spindle axis 30.
- the honing spindle 28 is sunk into the workpiece 12 or into the bore of the workpiece 12 to be honed by moving the horizontal honing unit 26.
- the workpiece 12 is rotated again by means of the rotation device (not shown) in such a way that the honing operations carried out can be remeasured and checked by means of the measuring device 34.
