How to improve the accuracy and grinding process of the cutting press machine
The accuracy of the cutting machine is a very important attribute, if the accuracy deviation, it is likely to lead to the waste of materials, of course, long-term wear will inevitably lead to the decline of the accuracy of the machinery, so how to improve the accuracy of the cutting machine? Here is a simple understanding of it!
High machining accuracy and low surface roughness. During grinding, the grinding blade blade n1P is often sharp, the blade edge radius P is also very small, and the cutting blade is very many, so it can cut a very thin layer of metal. The cutting thickness can be as small as several microns, so the residual area height is extremely small.
The grinding machine used for grinding has high accuracy, good rigidity and stability, and has a trace feeding mechanism to control the small cutting depth, which can perform microcutting, so as to achieve precision machining.
In dense cutting, the cutting speed is very high, such as ordinary external grinding p * 30 to 35 m/s, high speed grinding & gt; 50 m/s * when countless cutting blades cut from the surface of the workpiece at a very high speed, each cutting machine only cut a very small amount of metal from the workpiece, the residual area height is very small, which is conducive to the formation of low roughness surface.
Simple understanding of the grinding principle and function of the cutting press machine
Cutting pping machine is the inevitable type of machinery for light industry, the use and production of cutting machine in China has been quite perfect, but for the understanding of the cutting machine believe there are still a lot of not very understand, after all, simple operation know one is enough, the following is a simple understanding of the grinding principle of the cutting machine!
Grinding is the removal of fine metal layers from the workpiece from the surface of the grinding wheel.
The separate work of each grinding grain can be regarded as a cutting knife with a negative front corner, while the whole grinding wheel can be regarded as a milling cutter with multiple JJ teeth, but the teeth are composed of many scattered sharp edges, their shapes are different, the cutting edges are different, and the distribution is very irregular.
The towel is more sharp and more convex grinding grain, can obtain a larger cutting thickness and cut out the chips, not too convex grinding grain is just carved on the surface of the workpiece, the workpiece material is squeezed to both sides of the groove and uplift.
And the hydraulic cutting machine grinding blunt or concave grinding particles, they can only produce sliding on the surface of the workpiece.
Therefore, grinding essence death is the comprehensive effect of the three processes of cutting, cutting and wiping.
