Abstract

A cylinder block has functional surfaces machined by cutting and with at least one cylinder (5) with a coating. To simplify the production of the cylinder block, the cylinder block (1) has an inwardly projecting collar (25, 26) at the end of the cylinder (5) to delimit the cylinder (5) in the axial direction. The side of the collar (25, 26) facing away the from the cylinder (5) constitutes a stop for a suction extraction device (46) that serves for extracting excess coating material by suction.
