Foreword
This revised standard adopts ISO 3089.2005 "Machine overall self-centering chuck jaws manually check condition" (in English).
This standard is based on ISO 3089.2005 redrafted.
Because of the special needs of our industry, this standard at the time of adoption of international standards has been modified. The technical differences between a single vertical line labeled
Knowledge involved in their terms of margin.
This standard ISO 3089.2005 main technical differences are as follows.
--- Chuck nominal diameter of not more than 125mm and greater than the geometric precision chuck 500mm test tolerance values \u200b\u200bhave been adjusted;
--- G3 term geometric precision of tolerance values \u200b\u200bhave been adjusted;
--- G4 item inspection "test should be larger than the outer diameter of the ring arc diameter clamping jaws" to "test should be smaller than the outer diameter of the ring arc diameter clamping jaws."
For ease of use, this standard also made the following editorial changes.
--- Remove the foreword and introduction of international standards;
--- "This International Standard" be replaced by "this standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Geometric tolerances and reference symbol represented by China's relevant provisions of the standard;
--- Of ISO 3089.2005 referenced ISO 230-1.1996, with the corresponding GB/T 17421.1-1998 substitute;
--- Deleted references.
The standard proposed by China Machinery Industry Federation.
The standard metal cutting machine tools by the National Standardization Technical Committee (SAC/TC22) centralized.
This standard was drafted. Huhhot Zhonghuan (Group) Co., Ltd., Yantai Institute of machine tool accessories, and Zhejiang Machinery Co.,

The main drafters of this standard. Du Shu succeed, Zhang Guobin, when said Qing, Hejin Yao.
This standard is the first release.
Machine overall self-centering chuck jaws manually test conditions
1 Scope
This standard specifies two or more machines manually jaw self-centering chuck Geometric tests and the corresponding tolerances.
This standard applies to quick clamping of workpieces of different sizes overall hard jaw chuck.
This standard only defines the chuck rotation center of the workpiece correction accuracy test is not applicable to other dynamic performance tests, such as testing or folder balance
Clamping force testing.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research

GB/T 17421.1-1998 Test code for machine tools - Part 1. under no-load or finishing conditions Geometric accuracy of machines
(EqvISO 230-1.1996)
3 General Description
The standard of all dimensions and tolerances in millimeters (mm).
4 accuracy class
This standard specifies a precision.
5 Geometric tests
5.1 The main gear
Chuck clamping test rods (G3 test items) or ring test (test items ~ G7 G4 entry) should use the main gear, the main gear is a means
Given reference gear.
5.2 input torque
Geometric tests when the input torque should be the same, using the manufacturer's prescribed about 67% Chuck maximum allowable input torque.
5.3 test rods
Test rods for high-quality steel and hardened, in order to avoid damage to the chuck clamping force outer surface. The accuracy of the test rods should be consistent
GB/T 17421.1-1998 of A. 3, the same size bar examination requirements.
5.4 Inspection ring
5.4.1 General
Inspection ring/disk application quality steel and hardened, in order to avoid the chuck clamping force caused by damage to the surface, in order to reduce distortion test loop Movies
Loud, read the data should be close to the jaw.
5.4.2 Anti-claw ring with test accuracy
Anti-claw ring with test/plate accuracy should be in accordance with Table 1.
