Technical specification for rework manufacturing
1 Scope
This standard specifies the terms and definitions of mechanical remanufacturing machinery, basic requirements, post-processing inspection, safety and environmental requirements.
This standard applies to the mechanical product remanufacturing coating, cladding and other surface repair layer of mechanical processing.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
Basic Terminology of Mechanical Manufacturing Technology GB/T
Test and Evaluation of GB/T 25375 Metal Cutting Machine Tool Combined with Surface Coating
GB/T 28619 Termination Terminology
Method for quality inspection of remanufactured blanks GB/T 31208
3 terms and definitions
The terms and definitions defined in GB/T 4863 and GB/T 28619 apply to this document.
4 basic requirements
4.1 pre-processing requirements
4.1.1 Determine the processing area, scope and process method.
4.1.2 It should be determined that there are no defects that affect performance.
4.1.3 Clear the residual repair layer outside the processing area to prevent subsequent processing.
4.2 Process requirements
4.2.1 processing to consider the shape and position tolerance to determine its positioning and processing methods.
4.2.2 Check and trim the positioning datum to ensure that the geometric tolerances and dimensional tolerances meet the technical requirements. The machining shall be carried out in accordance with the technical regulations
get on.
4.2.3 When machining the remanufactured repairing layer, the corresponding tool, cutting parameters or special machining methods shall be used. The tool shall be of sufficient
Strength, toughness, abrasion resistance and rigidity.
4.2.4 Machining should use smaller cutting feed, cutting depth and lower cutting speed, and strengthen the cutting tool and repair layer cooling, anti
Only repair layer off, cracking, burns and so on.
4.2.5 remanufacturing coating should adopt grinding; remanufacturing cladding should adopt turning, milling or grinding and other processing.
4.2.6 should be based on the characteristics of different parts of the selection of different methods.
4.2.7 The workpiece should be checked and accepted according to the process, and it can be transferred to the next process after passing the inspection.
4.2.8 processing parts in the handling, storage, should prevent bumps, corrosion, deformation and other damage.
