There are many kinds of diamond tools, including single crystal diamond tools, polycrystalline diamond (PCD), polycrystalline diamond composite (PCD), CVD diamond tools and electroplated diamond tools. The most widely used diamond tools in the application of stone marking are molding milling wheel (die cutting), which is suitable for narrow marking. The circular saw blade will cut the stone material into a strip, milling milling wheel milling shape, suitable for wide and narrow marking production; Cut with diamond tools, suitable for wide marking. In addition, there are stone processing center and a number of marking processing methods.
1. Directly process with molding milling wheel. This is the most used processing stone marking, is also the most economical, the highest processing efficiency. It is faster to mark the shape of the ups and downs. This needs to make in advance and to process the line concave and convex contrary milling tools, grinding curves in the stone line machine, grinding wheel to prepare rough grinding, fine grinding, polishing three, use in turn can.
2, first rough machining with diamond tools, and then use milling wheel finishing, polishing. This method is suitable for marking wide or narrow shapes with large bumps. If the milling wheel directly processing wear, and cutting efficiency is relatively high circular saw blade first remove most of the excess material, and then milling wheel rough grinding, fine grinding, polishing.
3, cut with diamond tools, and then through copying machine grinding or manual polishing. This is suitable for processing more wide marking, cutting can get concave, convex two kinds of marking, such as good design, two kinds of marking can be used in a project, conducive to cost saving.
Diamond tool not only can be used for general turning, boring, milling, also successfully used in precision hole before processing to ensure that the photoresist line width is consistent with the design, and in need of electroforming photoresist developing clean, adjustment when electroforming electroforming conditions and parameters to get the best effect of electroforming, only to meet the above process for the preparation of micro spring to obtain better mechanical properties.
