| 摘要 |
The invention relates to a roughness measuring device (1), comprising a receiving device (2) for a feed apparatus (3), for passing a roughness sensor (4) over a workpiece surface. Said receiving device (2) comprises a measurement standard (24) having a measurement surface (25) near the roughness sensor (4). Preferably, the measurement standard (24) is arranged in a recess and secured to the receiving device (2), whereby the recess is formed in the wall of a drilling, for receiving the feed apparatus (3). As a result, the measurement surface (25) thereof is arranged within the receiving device (2), so that said surface is protected against contamination and damaging, but remains easily accessible. |
