Parallels V-blocks and surface plates for dimensional inspection

Parallels, V-blocks, and surface plates are instruments used in dimensional inspection to provide stable references and reliable checks on mechanical components. They are used in workshops, quality control, and metrology rooms, where support stability and the quality of reference surfaces directly affect measurement accuracy.

Inspection parallels are used for positioning and supporting parts during machining and inspection. Thanks to their ground surfaces and dimensionally stable steel construction, they provide stable and repeatable support. Cross parallel versions also allow cylindrical parts or components with irregular geometries to be handled, improving stability during measurement.

V-blocks are designed for checking shafts and cylindrical components. 90°, inclined, or magnetic V-blocks allow the part to be positioned correctly, making dimensional and geometric checks easier. The quality of the contact surfaces is essential to avoid errors during inspection.

Surface plates are the main reference for metrology inspection. Granite surface plates, thanks to their dimensional stability and wear resistance, provide a reliable surface for flatness checks and for use with instruments such as height gauges and dial gauges. Their non-magnetic material and long-term stability make them particularly suitable for metrology rooms.

Parallels, V-blocks, and surface plates are often used together to create a complete reference system during measuring operations. The correct choice of instrument always depends on the type of check, the size of the part, and the level of accuracy required.
