Foreword
GB/T 25661 "mobile overhead beam gantry machining center" is divided into two parts.
--- Part 1. Testing of the accuracy;
--- Part 2. Technical requirements.
This section GB/T 25661 Part 1.
This part is proposed by China Machinery Industry Federation.
This part of the National Metal Cutting Machine Standardization Technical Committee (SAC/TC22) centralized.
This section is drafted. Sichuan Changzheng Machine Tool Group Co., Ltd.
The main drafters of this section. Wang Xiaohui, Xu Bank of China, Liu Lixin.
Overhead beams mobile gantry machining center
Part 1. Testing of the accuracy
1 Scope
This section GB/T 25661 specifies the geometric precision crosshead overhead gantry machining center positioning accuracy and precision to work
Requirements and test methods.
This section applies to the work surface width 1000mm ~ 3000mm general purpose overhead beam mobile gantry machining centers and CNC
Overhead beams mobile gantry milling machine.
2 Normative references
The following documents contain provisions which, through reference GB/T 25661 in this section constitute provisions of this section. For dated reference documents
Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section
Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this
section.
GB/T 17421.1-1998 Test code for machine tools - Part 1. under no-load or finishing conditions Geometric accuracy of machines (eqv
ISO 230-1.1996)
GB/T 17421.2-2000 Test code for machine tools - Part 2. CNC axis positioning accuracy and repeatability of determination
(Eqv ISO 230-2.1997)

3 General requirements
3.1 Units
All this section and the corresponding linear dimension tolerances are in millimeters (mm) represents; angle dimensions in degrees (°), said angle deviation and the corresponding
Tolerance generally expressed as a ratio. However, in some cases for clarity, but also with microradians (μrad) or arcsec ( ") indicates its conversion relationship see
The following formula.
0.010/1000 = 10μard≈2 "
3.2 Implementation of standards
When using this section shall GB/T 17421.1-1998 in Chapter 3, in particular installation, spindles and other moving part of the machine before inspection
Member of the warmed air operation, testing methods and tools recommended accuracy.
3.3 Test order
Inspection order under this Part may not represent the actual test sequence. In order to make an inspection tool assembly and disassembly and inspection of convenience, can be arbitrary
Order of inspection.
3.4 Test Project
When the test machine, according to the structural characteristics must not test all of the items in this section. When testing requirements for acceptance purposes, can
Made by the user to select the manufacturer agree that some of the test items of interest, but these test items should be clearly stated at the time of ordering the machine.
3.5 inspection tool
Test tools provided in this section is only an example, you can use the same amount of instructions or have other tools to test at least the same accuracy.
Indicators should have a 0.001mm or higher resolution.
