Abstract
In modern production processing industry, grinding is an important machining operation, so the precise grinding technology is of great significance. To meet the strict precision requirements of modern products, the traditional grinding method is being abandoned and replaced by unprecedented flexible grinding technology. This paper mainly introduces the characteristics and application of flexible grinding, which enables grinding to be completed without a grinding machine.
1 Introduction
For hundreds of years, people have attached great importance to the grinding process in production. With the development of modern industry and the deepening of human understanding of grinding technology, traditional grinding methods are no longer suitable for the processing of high-precision products, and flexible grinding technology allows grinding to be completed without a grinding machine, which has created unprecedented opportunities for modern manufacturing.
Flexible grinding technology is also known as “non-traditional grinding.” According to the abrasives used, it can be divided into three types: reinforced grinding, self-vibrating grinding, and electrochemical grinding. All three types of grinding technology have been developed for modern production processing and have the advantages of low cost, high efficiency and sufficient precision.
2 Characteristics and Application of Flexible Grinding Technology
2.1 Reinforced grinding
Reinforced grinding is a flexible grinding technology that uses a reinforcing abrasive to grind the workpiece instead of a grinding wheel. In this process, the reinforcing tool does not itself rotate, but the surface of the workpiece to be processed is “dominated” by a certain relative motion, so that the abrasive grains in the reinforced abrasive are arranged reasonably and cut into the surface of the workpiece.
The characteristics of reinforced grinding are that a thin and hard contact layer is formed between the abrasive grains and the workpiece, allowing grinding to be completed more quickly and with greater precision. In addition, abrasive tools made of different materials can also be selected according to the processing accuracy requirements and the material of the workpiece.
2.2 Self-Vibrating grinding
Self-vibrating grinding is a flexible grinding technology that uses a self-vibrating abrasive to grind the workpiece. The vibration mechanism in the abrasive allows the abrasive grains to produce vibration when impacted by the workpiece and further cut into the surface of the workpiece. This makes grinding more efficient and precise.
In particular, self-vibrating grinding technology is suitable for the grinding of small and precise parts, and can be used to grind inner or outer curved surfaces of parts that are difficult to process with traditional grinding.
2.3 Electrochemical grinding
Electrochemical grinding is a flexible grinding technology in which an electrolytic solution serves as a grinding fluid and the workpiece is machined under the action of an electrochemical reaction. This technology combines the principles of electrochemical machining with the properties of precision grinding, so that grinding and electrochemical machining are both realized.
Electrochemical grinding has the characteristics of large depth of cut, good surface quality and low thermal damage to the workpiece. It can grind harder materials, such as high carbon steel or alloy steel, and is suitable for the processing of parts with deep grooves or internal contour surfaces.
3 Conclusion
Modern flexible grinding technology has made unprecedented progress in the fields of accuracy and efficiency. Nowadays, the processing requirements of precision products are no longer limited to traditional grinding machines, and flexible grinding technology can be used instead. Reinforced grinding, self-vibrating grinding and electrochemical grinding are widely used in the fields of automobile, aerospace, medical technology and other precision processing. In the future, flexible grinding technology will become an important trend in the development of precision grinding technology.
