Measuring a cylinder
Prerequisite
Cylinder path is cleaned.
Check
- Adjusting measuring screw to nominal dimension of cylinder bore.TECHNICAL DATA SPECIFICATIONS
Cylinder bore Distance of the upper edge of the cylinder path to the measuring point 0 mm... 60 mm Diameter of cylinder bore 82.000 mm... 82.014 mm Permitted irregularity of the cylinder bore 0.007 mm Distance of the upper edge of the cylinder path to the measuring point 60 mm... 80 mm Diameter of cylinder bore 82.008 mm... 82.022 mm Permitted irregularity of the cylinder bore 0.007 mm Distance of the upper edge of the cylinder path to the measuring point 80 mm... 115 mm Diameter of cylinder bore 82.021 mm... 82.037 mm Permitted irregularity of the cylinder bore 0.007 mm Distance of the upper edge of the cylinder path to the measuring point 115 mm... 135 mm Diameter of cylinder bore 82.033 mm... 82.057 mm Permitted irregularity of the cylinder bore 0.010 mm - Insert internal measuring device into micrometer and set to zero.
- With the internal measuring device, measure the cylinder at the following points and check the deviations from the nominal dimension.
- Lower third of the cylinder bore in direction of travel,
- Lower third of the cylinder bore transversely to direction of travel,
- Middle third of the cylinder bore in direction of travel,
- Middle third of the cylinder bore transversely to direction of travel,
- Upper third of the cylinder bore in direction of travel,
- Upper third of the cylinder bore transversely to direction of travel.
