Multi-purpose lathe
The geometric accuracy and working accuracy requirements of the multi-purpose lathe in the non-standard factory are specified, so the inspection method is JB/I 8483.196
2 The standard is applicable to multi-purpose lathes with a maximum rotation of 250~-190mm and a maximum length of 1000mm. 2 Reference standards
The texts contained in the following standards are the referenced texts of this standard. When this standard is published, the versions shown are valid and all new versions will be revised; the parties using the standard should explore the possibility of continuing to use the latest versions of the following standards, [B2G7082 3 General requirements for the inspection of the accuracy of cutting machines
3.1 When using this standard, refer to J7. In particular, the installation of the machine, the idle operation of the ten axes and other components, and the inspection of the accuracy of the machine.
3. 2 This standard indicates the minimum precision of the items, and does not represent the actual order. For the purpose of installation inspection and inspection, the inspection can be carried out in any order.
3. When inspecting the working accuracy of this standard, the test piece should be inspected after fine turning. 3.4: * When the actual measured length is different from the length specified in the technical standard, the difference should be made according to the provisions of 7.3.1.1 of JB2G7082. When the result is 1c.mm, it should still be calculated as 0.005mm. 3.5 The direction parallel to the bed guide rail is called the weaving direction, and the horizontal direction from the lower number is the weaving direction. 3.6 Refer to 3.1 in JTI367082 to adjust the installation water level, and place the template in the guide position. At the west end of the bed guide rail (or through a special Month's storage board) Place the water meter, the readings of the half-meter car are not displayed as U. (8/0.
