In this paper, aerial work platform lifting platform milling machine precision standard is applicable to the working width in 200~500mm, the general purpose of the horizontal and vertical milling machine. The standard list of precision test item order, does not represent the actual inspection order. In order to convenient assembly and disassembly inspection tools and inspection, can be tested in an arbitrary order.
According to the user and manufacturer protocol, test items can increase or decrease.
(1) the use of this standard shall be present as JB2670-82 (test code for metal cutting machine tool accuracy), especially the precision test before installation, shaft and other parts of the air temperature rise test method.
(2) the installation level with reference to Article 3.1 of JB2670 adjustment of machine tool. The middle position of the worktable is arranged on the trip. Place the central level gauge in the workbench, level in the longitudinal and transverse readings are not more than 0.04/1000,
(3) testing of the working accuracy, try to face test piece should be carried out in the fine milling after. Fine milling cutting dosage recommended: 0.1mm depth of cut; feed per tooth site 0.1 mm,
(4) when the side length and the standard length is not at the same time, tolerance should be based on the provisions of section 220.127.116.11 of the JB2670 to Nit conversion. According to the length of. The conversion result is less than 0.005mm, as 0.005mm.
