GB/T 21686-2008 Woodworking machines—Slot mortising machines—Nomenclature and acceptance conditions
Basic Information
Scope
This standard specifies the terminology for all parts of the horizontal dovetail machine (hereinafter referred to as the machine tool), and, with reference to GB/T 17421.1—1998, stipulates the geometric accuracy inspection of the machine tool and provides the corresponding tolerances, applicable to machine tools for general use and with ordinary accuracy. This standard only stipulates the accuracy inspection of the machine tool and is not applicable to the running tests of the machine tool (such as vibration, abnormal noise, and creep of components), nor to the characteristic tests of the machine tool (such as speed and feed rate), which are generally conducted before the accuracy inspection of the machine tool. This standard does not impose strict requirements on the working accuracy inspection of the machine tool. It shall be stipulated separately in the preliminary agreement between the user and the manufacturer.
