TS ISO 7570

TS ISO 7570 is a woodworking-machine standard covering the terminology, acceptance conditions and geometric inspections for surface planing and thicknessing machines. It brings together the names used for the main machine parts and frames the geometry checks used for general-purpose machines of normal accuracy.

Terminology and the naming of machine parts

In a terminology standard of this kind, the main value is consistency: the same machine element should not be described by different names in different documents. For surface planers and thicknessers, terms for elements such as the table, cutterblock, feed arrangement and fence are harmonised so that technical manuals, inspection sheets and catalogues use the same language. In general technical practice, that makes operation, maintenance and record comparison much clearer.

Geometrical tests and permissible deviations

The standard gives geometrical tests with reference to ISO 230/1, together with the corresponding permissible deviations. In practical engineering terms, geometrical inspection is about the relative alignment of axes, tables and guiding surfaces, because those relationships strongly influence planing accuracy and surface quality. The stated scope is limited to machines for general-purpose use and normal accuracy; machines intended for special duties or higher precision may need different acceptance criteria.

From a broader technical perspective, a surface planer prepares one face of a workpiece against a reference plane, while a thicknesser produces a target thickness between the two faces. Pairing terminology with accuracy checks is important because it supports both clear communication and measurable acceptance of machine geometry.

• Intended for general-purpose use.
