Major Trends in Belt-Sanding Belts' Grinding


Since the 1960s, industrialized countries such as Europe, the United States, and Japan have made new breakthroughs in belt-sanding belts' grinding technology and belt-sanding belts' manufacturing technology, achieving tremendous achievements, and have entered a new stage of modernization. From daily soup ladles to aerospace components, belt-sanding belts' grinding technology is widely used in all industries, and new types of machines continue to emerge. Belt-sanding belt grinders are developing towards small size, strong power, high efficiency, and wide belt belt-sanding belt grinders. For example, belt-sanding belt grinders produced in the United States have a maximum width of 5.0m and a maximum power of 200kW. Then, our sanding belt manufacturers will list the features of belt-sanding belts grinding.


Automation, numerical control, and intelligence of belt-sanding belts' grinding


In recent years, the development of numerical control grinders and grinding machining centers has been rapid, and modern technologies such as CNC have been combined with belt-sanding belts' grinding. With the development of artificial intelligence and sensing technology, intelligent grinding has become an important direction. Experimental research on grinding requires a lot of manpower and material resources. Using computers for simulation of the grinding belts for metal grinding process is also an important direction. Currently, the molecular dynamics theory is introduced into the study of grinding mechanisms and simulations, which is a new method for studying grinding mechanisms.


Precision and ultra-precision of belt-sanding belts' grinding


Grinding has always been an effective processing method for achieving higher precision, surface integrity, and strict manufacturing consistency. Materials such as ceramics and microcrystalline glass, which are difficult to process, can currently only be processed by grinding. Using grinding micropowders with a particle size of only a few nanometers for ultra-precision grinding can obtain excellent surface quality. The Ra of ultra-precision grinding is between 0.012μm and 0.025μm, and the Ra of mirror polishing is below 0.012μm. The development of ultra-precision composite processing is also very fast, such as fluid polishing and ultrasonic vibration grinding.


Efficiency and strength of belt-sanding belts' grinding


High-efficiency deep grinding can be regarded as a combination of gradual entry grinding and ultra-high-speed grinding, but the process and mechanism of grinding are not yet clear. In order to form a complete theoretical system, a comprehensive study is needed on the grinding chip formation mechanism, material deformation mechanism under high-strain rate, grinding force, grinding temperature, grinding residual stress, etc. belt-sanding belt grinding has been successfully applied to strong grinding, achieving large removal rates and high metal removal rates. The cutting rate of cast iron has reached 3 x 105mm3/s, and the belt-sanding belts' grinding depth can reach 3-4mm in one pass. Its machining efficiency is 5-10 times higher than that of milling.


High performance of belt-sanding belts' grinding abrasives and grinding tools


The continuous development of modern mechanical processing has increasingly high requirements for materials processing, which has led to the continuous research and use of new types of super-hard abrasive tools for precision, ultra-precision, and high-efficiency grinding. New and super-hard abrasives and grinding tools include: ceramic corundum abrasives, which are chemically ceramicized, broken into particles after being processed by a crystal ceramic gluer, and finally sintered into abrasives. It has good toughness, self-sharpening, and long life; synthetic diamond, used for grinding ultra-hard and brittle materials, hard alloys, granite, gemstones, optical glass, ceramics, etc., consisting of three parts: abrasive layer, transition layer, and matrix; cubic boron nitride, whose abrasive toughness, hardness, and durability are 100 times that of corundum abrasives. It is suitable for high-speed or ultra-high-speed and difficult-to-process materials such as high-speed steel and heat-resistant steel.
