Remanufacturing is an extremely important part of manufacturing, and, it must be seamless, if the slightest lack of attention will slip into the concept of repair. Remanufacturing and manufacturing, just before manufacturing the choice of raw materials are different. Manufacturing blanks are selected from the initial processing of raw materials, remanufacturing blanks are selected after the retirement of non-vulnerable original surface engineering processing and become the subsequent manufacturing process selection of processing benchmarks, technical parameters and the use of equipment both design requirements are identical. Remanufacturing needs to find the benchmark is to find the original manufacturing datum or datum left behind. Then based on the benchmark and the original deviation between the shape of the position, for value assessment and development of remanufacturing program. In the machining process must be deformed defects in the old parts of the holes and surfaces by the surface engineering treatment, with the original manufacturing benchmarks accurately positioned fixtures and fittings supporting the rigid machine tool processing to restore the benchmarks, grinding and honing equipment to remove the rigid machine tool processing of the cutting marks left behind, to ensure that the benchmarks match the size and accuracy, absolutely no air-floating stationary cutting and honing equipment without positioning or low-precision machine tool processing. Speaking of which it is necessary to detail the difference between remanufacturing and overhaul. Remanufacturing is the first parts must be restored to the benchmark, and then fully in accordance with manufacturing standards to restore functionality. Overhaul is limited by the conditions, can only realize the function of partial restoration. Because, the decommissioning can be remanufactured parts are used through long-term operation, full of abrasion, so that the parts of the intrinsic stress can be fully released after the occurrence of morphological changes and benchmark deviation, resulting in parts of the bias rule wear. So find the benchmark is the key measure of remanufacturing, and overhaul does not have the manufacturing standard testing and processing equipment, can not realize the benchmark recovery. This is the fundamental difference between the two. Note: Benchmarking - the key to seamless integration of remanufacturing and manufacturing. Parts and components remanufacturing equipment required in three process stages, the first process stage is used to decontamination and reusable value assessment and analysis equipment, the second process stage surface engineering equipment, the third process stage is identical to the manufacturing, equipped with design standards in line with the benchmark tooling equipment.
The actual real sense of the remanufacturing equipment is a general testing, processing machine tools and surface engineering equipment, retrofitting parts benchmarking and positioning of the tooling. However, it must be remembered that the saying "the upper beam is not the lower beam is not crooked", there is no high-precision equipment is not possible out of high-precision products. There is also a saying that "manufacturing is easy to correct difficult", never use simple repair equipment into the remanufacturing, because, remanufacturing parts need to restore the benchmark. Finally, to tell the "serious" word, only serious to be careful, do not be superstitious about the so-called special remanufacturing equipment.
"Remanufacturing" the first key technology ---- retired parts assessment and testing. It is recommended that the use of CNC machine tool equipment to change the tool for contact or detection sensors, the parts into the machine tool with a benchmark positioning special fixtures within the platform for three-dimensional testing, the equipment has a flaw detection function, and there is a direct output of the part parameters and test data information can be networked with the computer function of the "black box".
