Foreword
GB/T 16462 "CNC lathes and turning centers Test conditions" is divided into eight sections.
--- Part 1. Horizontal Geometric tests for machines;
--- Part 2. Vertical Geometric tests for machines;
--- Part 3. Geometric tests inverted vertical machine;
--- Part 4. linear and rotary axes positioning accuracy and repeatability of the test;
--- Part 5. feed, speed, and interpolation accuracy test;
--- Part 6. finishing accuracy test specimen;
--- Part 7. Evaluation of contouring performance in the coordinate plane;
--- Part 8. Evaluation of thermal deformation.
This section GB/T Part of 816,462.
The partial modification using ISO 13041-8.2004 "Part 8 CNC lathes and turning centers Test conditions. Evaluation of thermal deformation" (English
Chinese Version). About the technical differences have been incorporated into the body and they are involved in terms of the margin of a single vertical line identification.
This portion of the ISO 13041-8. compared to 2004, the main differences are.
--- Some statements to applicable international standards applicable to our standard formulation;
--- Chapter 1 Scope to add a "linear axis travel greater than 2000mm CNC lathes and turning centers can also refer to the use of"
Terms;
--- Note in the 6.2 "for example, at 70% of maximum spindle rpm 3min, then the spindle stop 1min" to "recommendations by the spindle
Times to form 30% of max running 3min, 50% like max running 4min, 70% like max running 3min, 100% like max running 1min, the master
Axis stop 1min ";

CNC lathes and turning centers Test conditions
Part 8. Evaluation of thermal deformation
1 Scope
This section GB/T 16462 specifies the evaluation of thermal deformation of CNC lathes and turning centers of the machine structure and positioning systems.
This section applies to linear axis travel 2000mm CNC lathes and turning centers. The number of linear axis travel greater than 2000mm
Control lathes and turning centers also refer to use.
This section specifies three test methods, namely.
--- Changes in ambient temperature error checking;
--- Examination by the thermal deformation caused by the rotation of the spindle;
--- Examination by a linear axis thermal distortion caused by the movement.
It should be noted that the test described in this section does not give a specific tolerance value.

4 Short Description
4.1 Referring to GB/T 17421.3-2009
Use GB/T 16462 in this section should reference GB/T 17421.3, especially describes the installation, measuring machine test method before
And test results indicate.
4.2 Test order
This section tests can be carried out separately, it can also be carried out in any combination.
4.3 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, by
Supplier (or manufacturer) agreement, the user can select a number of items of interest for inspection. However, these items must be ordered in the test machine
When clearly. If no test items and related costs of the agreement, only with reference to this part of the acceptance of the contracting parties are not
Binding.
