1 Scope

This standard specifies two, three, four milling machine (hereinafter referred to as the machine) The term of each part, while referring to GB/T 17421.1-1998, Regulation Geometric accuracy of machines set up and test the accuracy of inspection work, and given the appropriate tolerances for general use, general precision machine tools. This standard only requires that the machine accuracy test, does not apply to running test machine (such as vibration, unusual noise, reptiles and other parts of the seized Experience), does not apply to machine features test (such as speed, feed rate, etc.), these tests are generally advised to test for accuracy in front of the machine.

3 Short Description

3.1 standard in all dimensions and tolerances are in millimeters. 3.2 This standard should be used with reference to GB/T 17421.1-1998, especially the test installation, spindles and other moving parts of the machine before Temperature, and test methods. Gage error should not exceed 1/3 of the tolerance of the subject project. 3.3 standard geometric accuracy test order is given by the machine tool assembly sequence, which is not limited by the order of the actual inspection time. In order to facilitate Installation and testing of the seizure, inspection in any order. The standard test given project must be itemized or not always be able to test 3.4 test machine. 3.5 Test Project selection is determined by the user, and in agreement with the manufacturer, clearly defined at the time of ordering the machine. Selected test Projects are often of interest about the performance of your machine. 3.6 movement in the direction of the workpiece called longitudinal movement. 3.7 When determining the minimum conversion time measuring range is different tolerances specified in this standard on measuring range should be considered a value of 0.01mm tolerance (See GB/T 17421.1-19982.3.1.1).
