GB/T 14303-2008Woodworking machines -- Single blade circular saw benches with or without travelling table -- Nomenclature and acceptance conditions (English PDF)

Foreword

This standard is identical with ISO 7008. 1983 "Woodworking machines with or without traveling table single blade circular saws - Nomenclature and acceptance Article Member "(in English).

For ease of use, this standard made the following editorial changes.

--- "This International Standard" be replaced by "this standard";

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Remove the French term and Appendix A;

--- Deleted international standards foreword;

--- Increasing the normative references of Lead;

--- To ISO 7008. 1983 references to other international standards, with the international standard has been adopted as the standard instead of the corresponding country.

This standard replaces GB/T 14303-1993 "universal circular saw machine precision" and GB/T 14387-1993 "vertical sectional circular saw Machine precision. " this standard and GB/T 14303-1993 There are differences compared to.

--- Modify the standard name;

--- Increasing the term;

--- Part of the geometric accuracy of the text items and made editorial changes, delete the G16;

--- Remove the work of the accuracy.

The standard proposed by China Machinery Industry Federation.

This standard by the National Woodworking Machine and Tool Standardization Technical Committee (SAC/TC84) centralized.

This standard was drafted. Asian worker (Weihai) Co., Ltd., Hangzhou Lin'an Nanyang Woodworking Machinery Co., Ltd.

1 Scope

This standard specifies the terms of each part with or without traveling table single blade circular saws (hereinafter referred to as machine tools), taking GB/T 17421.1-1998, provides geometric precision machine testing, and given the appropriate tolerances for general purpose, normal precision Machine.

This standard specifies only the geometric accuracy of machine tool inspection, does not apply to running test machine (such as vibration, unusual noise, crawling parts Inspection, etc.), does not apply to machine features test (such as speed, feed rate, etc.), these tests are generally advised before testing the geometric accuracy of machine tools get on.

The standard accuracy of machine tools for working without mandatory inspection, which should be between the user and the manufacturer prior agreement separately.

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 Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

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)

3 Short Description

3.1 standard in all dimensions and tolerances are in millimeters.

3.2 This standard should be used with reference to GB/T 17421.1-1998, especially the test installation, spindles and other moving parts of the machine before Temperature, and test methods. Gage error should not exceed 1/3 of the tolerance of the subject project.

3.3 standard geometric accuracy test order is given by the machine tool assembly sequence, which is not limited by the order of the actual inspection time. In order to facilitate Installation and testing of the seizure, inspection in any order.

The standard test given project may not always be necessary or itemized inspection 3.4 inspection tools.

3.5 Test Project selection is determined by the user, and in agreement with the manufacturer, clearly defined at the time of ordering the machine. Selected test Projects are often of interest about the performance of your machine.

3.6 movement in the direction of the workpiece called longitudinal movement.

3.7 When it is determined tolerance range differs from the measurement of the standard measurement range should be considered a minimum conversion value of tolerance 0.01mm (see GB/T 17421.1-1998 in 2.3.1.1).
