Most of the metal sand wheels of sintering metal-binding agents are mostly made of bronze and other metals as binding agent. It is made of high -temperature sintering method. Its combination of strength, good moldability, high-temperature resistance, good thermal wear resistance, long service life, can withstand large loads, can withstand large loads Essence
Because the sintering process of the metal sand wheel inevitably shrinks and deforms, the metal sand wheel must be shaped before use, but it is difficult to repair the metal sand wheel.
At present, the commonly used metal sand wheels are not only time-consuming and labor-intensive, but also the trimming process has been shedding more.
In recent years, scholars from various countries have successively carried out research on the application of special processing methods to repair metal-binding diamond metal sand wheels. It mainly includes the electrolyte repair method and a compound amendment to the electro-spark repair method.
'Electrolytic trimming method is fast, but the plastic surgery accuracy is not high; the plastic surgery accuracy is high, both plastic surgery and sharpness, but the plastic surgery speed is slow; Method, etc., the repair effect is better, but the system is more complicated, so the repair problem of sintering diamond metal sand wheels still has not been solved well.
In addition, because the manufacturing process of the diamond sand wheel determines its random appearance, the geometric shape, distribution, and cutting blade are inconsistent, so only a few higher cutting blades are cut into the workpiece when grinding, which limits the grinding quality. The efficiency of cutting efficiency is further improved.
