Precision forming numerical control blade edge grinding process

Abstract

The invention belongs to the technical field of alloy blades, and discloses a precision forming numerical control blade edge grinding process. The process is characterized in that a to-be-ground bladeis installed on a grinding machine, a grinding wheel with the specification of D36 is installed on the grinding machine for accurate grinding, and the feeding speed of the grinding wheel is 0.06 mm / S. The scheme has the beneficial effects that when the grinding speed of the grinding wheel with the specification of D36 is 0.06 mm / S, the arc size of the machined hard blade is stable, a notch is prevented from appearing in the hard alloy blade, and the grinding speed of 0.06 mm / S is a machining parameter for the most stable efficiency and size.

Description

technical field [0001] The invention belongs to the technical field of alloy blades, and discloses a sharpening process of precision forming numerically controlled blades. Background technique [0002] In the cutting process technology, the production and processing technology of the blade is of great significance. It directly affects the level of machining efficiency and the quality of machining, and is the key to the continuous development of cutting technology. As a blade material, cemented carbide can meet the requirements of modern cutting technology of high cutting speed, high red hardness and high durability, and has penetrated into various fields of mechanical processing. The high hardness and high wear resistance of cemented carbide blades make it difficult to sharpen, and the sharpening process has become a bottleneck in its popularization and application. [0003] The sharpening process of existing cemented carbide blades includes the following types: [0004] ...

Problems solved by technology

The above process is a dynamic balance process, which not only avoids the excessive consumption of the grinding wheel, but also automatically maintains the grinding ability of the grinding wheel surface. However, this technology is a new sharpening technology, and its sharpening process is still immature, which needs to be further improved. explore

[0006] 3. Mechanical sharpening of diamond grinding wheel, among many sharpening methods, the most mature and effective is diamond mechanical sharpening. Under reasonable grinding process parameters, mechanical grinding of diamond grinding wheel can obtain other grinding process methods that are difficult to control It achieves the best blade edge quality and smooth front and flank surfaces, but compared with other sharpening processes, it has disadvantages such as high grinding force, low sharpening efficiency, and large grinding wheel loss.

Therefore, domestic and foreign studies on the grinding process of cemented carbide blades mostly focus on the research work on the grinding efficiency and the wear ratio of the grinding wheel, while there are few studies on the impact of different types of diamond grinding wheel grinding processes on the grinding quality.
