Abstract
The invention relates to a method for the surface processing of a component by flow grinding, comprising the following steps: (a) providing a blank (1), (b) flooding at least one surface of the blank (1) with a fluid carrier material containing grinding particles, wherein the blank (1) is rounded at positions at which, during flooding, the flow direction (25) of the fluid carrier material containing the grinding particles changes and, at positions at which a flow separation occurs on the finished component, additional material (5) is attached such that a flow separation at the beginning of the flooding operation is prevented.

A method for the surface processing of a component by flow grinding, comprising the following steps:
- (a) providing a blank,
- (b) flooding at least one surface of the blank with a fluid carrier material containing grinding particles,
- wherein the blank is rounded at positions at which, during flooding, the flow direction of the fluid carrier material containing the grinding particles
- changes and, at positions at which a flow separation occurs on the finished component, additional material is attached such that a flow separation at the beginning of the flooding operation is prevented.
The method as claimed in one of claims 7 to 9, wherein the concavely running surface has a curvature with a radius in the range of from 0.5 to 5 times the hydraulic diameter of the duct.
The method as claimed in claim 1, wherein, in the case of a surface over which flow passes that forms a wall of a duct, in which the duct has a widening in which the duct is widened from a region with a first hydraulic diameter to a region with a second hydraulic diameter, in which a transition portion of the wall of the duct between the region with the first hydraulic diameter and the region with the second hydraulic diameter has an angle of between 7° and 90° with respect to the main flow direction, in which the surface over which flow passes runs convexly at the transition from the region with the first hydraulic diameter to the transition portion.
