GB/T 25660.1-2010CNC small size worm milling machines - Part 1: Testing of the accuracy (English PDF)

3.1

section all linear dimensions are in millimeters (mm) as the unit; angle deviation is mainly represented by the ratio. In some cases the

Clear, but also with microradians (µrad) or arcsec ( ") as the unit in terms of its relationship formula below.

0.010/1000 = 10 × 10-6 = 10µrad~2 " 3.2 Use this section shall GB/T 17421.1, especially heating pre-installation testing tools, spindles and other moving parts, testing

Recommended methods and inspection precision tools. Installation of the machine level and ambient temperature should meet the following requirements.

--- According to GB/T 17421.1-1998 3.1 Adjustment of the machine installation level. The level meter on the mounting plate, a level in

Vertical and horizontal readings are not more than 0.04/1000;

--- When test, the ambient temperature should be maintained at 20 °C ± 2 °C. Machine Tool and Gage placed a long enough time in the measurement environment to

Ensure steady state is reached before the test.

3.3

part of the order given in the test project does not represent the actual inspection order. In order to facilitate assembly and disassembly inspection and testing tools, according to any one of

Italian order of inspection.

3.4

inspection tools, according to the structural characteristics of the machine does not have to test all the items in this section. For the purpose of acceptance testing requirements

When, by the user to obtain the manufacturer agreed to choose some interesting test items, but these items should be clearly stated at the time of ordering the machine.

Test tools specified in section 3.5 of example only, you can use the same indicates the amount and precision of other inspection tools. Indicators should have

0.001mm or higher resolution.

3.6

working accuracy test, test specimens shall be carried out after finishing.

3.7

When the software can be used to compensate for some of the test items deviation, the user and the manufacturer's protocol press, can use or not use these compensation

Inspection-related projects under the circumstances. When using a software compensation, should be indicated in the test project.

3.8

When the length of the measured length with the provisions of this section are not at the same time, it should be able to measure the length tolerance GB/T 17421.1-1998 in

Provisions 2.3.1.1 translated. Result of the conversion is less than 0.002, based upon the 0.002 meter.

3.9

axis parallel to the axis of the spindle axis is Z-axis perpendicular to the spindle axis of the X-axis.
