Today, with the rapid development of science and technology, many electrical equipment are developing in the direction of refinement.
The development of nanotechnology and the breakthrough of the Moore's Law of integrated circuits are to take humans to a smaller "small" microcosm.
There are cutting places where there are manufacturing, and manufacturing is also inseparable from drilling technology.
Drilling in IPhone and Ipad manufacturing processes
Processing of spinnerets for textile spinnerets
Precision machining of the fine ball pen water outlet
Micro-hole drilling in the design and manufacture of VLSI
Drilling of precision components in the aerospace sector
Drilling of high-grade materials such as carbon fiber and graphene
Drill-type tools are an essential tool in the processing of these fields.
The design and processing of drill bits is full of technical difficulties. With the refined pursuit of processing requirements, the accuracy of the drill tool is getting higher and higher.
The manufacturing requirements for drill tools are becoming more and more demanding, and they are inseparable from the superb precision polishing professional grinding wheels.
When it comes to the polishing of carbide tools, it is necessary to mention the Norton® Winter Flut Polish polishing wheel.
After the tool is rough grooved, in order to achieve better size and precision, a polishing process is required to obtain a better surface finish.
The grain size of the polishing wheel has been developed from D20 and D10 to D3 and D1 in order to pursue a more perfect edge quality.
The Saint-Gobain Flute Polish wheel is a rubber-bonded grinding wheel developed in Germany and is mainly used in the polishing application of drill-type rotary tools.
Flute Polish wheels are based on Saint-Gobain's newly developed, flexible rubber bond that fits perfectly on the surface of the workpiece and easily handles workpiece surfaces with large polished areas.
Flute Polish grinding wheel has good wear resistance and can achieve perfect mirror polishing effect; it can shorten the processing cycle of polishing process, improve production efficiency and further reduce the comprehensive cost of tool processing.
