Foreword
This Standard replaces GB/T 9061-1988 “General Specifications for
Metal-Cutting Machine Tools”. This revision compiles in accordance with GB/T
1.1-2000 “Directives for Standardization - Part 1. Rules for the Structure and
Abstract of Standards”. Standard construction and technical content have been
adjusted and modified; specification is more specific; the operability of this
Standard has been improved.
Compared with GB/T 9061-1988, the main revisions in this Standard are as
follows.
- In accordance with the requirements specified in GB/T 1.1, “Contents”,
“Foreword” and “Introduction” are added. Article expression of this
Standard meets the requirements; literal phrasing is concise and definite;
content, format and diagrams are modified according to drafting rules;
- The construction of this Standard is adjusted, with the cancellation of
previous standard’s Chapter 4, “Quality of Processing and Assembling”
and chapter 5, “Quality of Appearance”, which are merged into Chapter 3
of this Standard. The original heading, “Basic Requirements”, is changed
to “Technical Requirements”. Chapter 6 in the previous standard is
changed to Chapter 4 in this Standard, with the original heading
“Acceptance Inspection” changed to “Inspection and Acceptance”.
“Technical Requirements” and “Inspection and Acceptance” are highlighted
as two main compositions in this Standard;
- The heading of Chapter 1, “Subject Content and Application Scope”, is
changed to “Scope”; and the expression of application scope in the
previous standard is modified so as to definite the applicable limits and
objects;
- “Numerical Control System” is added to Chapter 3 in this Standard;
correspondingly “Numerical Control System” is added in Chapter 4;
- For technical requirements related to people’s health and safety that
belong to content of compulsory standard, 3.8 “safety and healthy” in the
previous standard has been revised significantly (see 3.9 in this edition) in
accordance with principle of direct quote;
- Referencing to overseas advanced standards, and considering domestic
manufacturing level at the present and principles of improving products
quality, the continuous running time of numerical control machine in 6.6.10
Introduction
This Standard replaces GB/T 9061-1988 “General Specifications for
Metal-Cutting Machine Tools”. This Standard is compiled in accordance with
requirements specified in GB/T 1.1-2000; in addition, the standard construction
and technical content are adjusted and enhanced as well. The previous edition
of GB/T 9061-1988 is JB 2278-78 “General Specifications for Metal-Cutting
Machine” that was issued by the former Ministry of Machine Industry, which
has been implemented for 15 years. GB/T 9061 is the general specification
(also called general standard) for fundamental and common quality
requirements of machine tool. The technical requirements related to product
design, manufacturing, inspection and acceptance are relatively systematic
and complete. It promotes the development of machine tool’s product quality
standard system, and plays a vital role in upgrading the manufacturing
technology level and product quality.
GB/T 9061, together with different kinds of product-technology conditions of
machine tool (also called sub standards) that were formulated for
supplementary and specific purposes, constitutes the technical basis to
evaluate the product quality.
General Specifications for Metal-Cutting Machine Tools
1 Scope
This Standard specifies both the fundamental and common technical requirements of
metal-cutting machine tool (hereinafter referred to as machine tool, including modular
machine tool and machine tool accessories).
This Standard is applicable to machine tool’s design, manufacturing, inspection and
acceptance. According to service performance and construction, different kinds of
machine tools may compile corresponding product-technology standards, and make
supplements to technology index, evaluation methods and inspection projects.
