Summary of the invention
A kind of adhering method that is used for gem products polishing processing is provided during purpose of the present invention, it with thickness less than 4.50mm, after the laminar band central through hole gem products of cylindrical (D)/highly (H)＞3 is bonding, polish processing again, can guarantee the axiality of gem products, the cylindrical polishing of gem products fully, cylindrical and hole perpendicularity are good, and simple to operate in addition, the utilization rate height of mill in polishing process, the advantage of not wasting abrasive material.
Technical scheme of the present invention has following steps:
1. several cylindrical tolerances gem products that is 0.01～0.02mm is through and forms the gem products string on the metal mandrel, and the through hole of gem products and the gap of metal mandrel are 0.005～0.01, and the gem products string is heated to 130～150 ℃;
2. the gem products string after the heating is placed on the bonded adhesives of thawing, and each gem products on the loosening gem products string flows between each gem products bonded adhesives;
3. remove the bonded adhesives on gem products surface, compress the two ends of gem products string;
4. the gem products string that rolls, bonding the finishing of gem products that is about to have axiality.
Adopt the inventive method, owing to metal mandrel gem products is cascaded, and the gap of jewel hole and plug has only 0.005～0.01, so can guarantee the axiality of gem products.Metal mandrel is with the gem products located in series, accurate positioning between each jewel, between the jewel bonding easily, bond quality is good, and the bonded adhesives materials can significantly reduce, and bonding material is few on the gem products, therefore, gem products is when carrying out the cylindrical polishing, and cylindrical and hole perpendicularity are good, and the surface quality of the burnishing surface of gem products is good.Before bonding, detect each gem products, the cylindrical tolerance of controlling each gem products is 0.01～0.02mm, therefore can guarantee that the circularity of bonding gem products is in 0.02mm.
The present invention, polishes after gem products is bonded together owing to metal mandrel gem products is cascaded, and does not need in the bonding process gem products is adjusted circularity and axiality one by one, and is therefore simple to operate.The gem products quantity that can process at same mill simultaneously increases the utilization rate height of mill, the advantage that the utilization rate of abrasive material also increases.
