Rotogravure Cylinder Making Copper Grinding Wheel Grinding Stone Process And Quality Control Principle

Principle of engravure cylinder Grinding Process: Grinding (grinding wheel grinding process) achieves the processing goal through the relative movement of the grinding wheel surface and the workpiece surface. Its core mechanism is that when the abrasive particles on the grinding wheel surface come into contact with the workpiece surface, the rotation of the grinding wheel generates a relative speed. This relative speed causes the abrasive particles to perform staggered cutting and grinding on the workpiece surface, thereby achieving the processing effect. The grinding wheel, as the active body, not only transmits power and energy, but also performs cutting, grinding and polishing functions at the same time. This process ensures precise processing and high-quality surface finish of the workpiece surface.

Working principle of grinding: The rotogravure printing cylinder making copper grinding process of grinding wheel can be divided into three stages: sliding, plowing and cutting, namely cutting, grinding and polishing.

1.The influence of adjustment of grinding process parameters on workpiece surface roughness and quality: 1. The influence of workpiece rotation speed on workpiece surface roughness and quality: When other conditions remain unchanged, as the workpiece rotation speed increases, the scratches on the workpiece surface become longer and the workpiece surface quality decreases.

2. The influence of grinding wheel rotation speed on workpiece surface roughness and quality: When other conditions remain unchanged, as the grinding wheel rotation speed increases, the cutting and polishing effects increase, and the workpiece surface quality improves.

3. The influence of grinding wheel grinding pressure on the surface roughness and quality of the workpiece: When other conditions remain unchanged, as the grinding wheel grinding pressure increases, the cutting and polishing effects increase, and the surface quality of the workpiece improves.

4. The influence of grinding wheel moving speed on workpiece surface roughness and quality:
When other conditions remain unchanged, as the lateral moving speed of the grinding wheel increases, the cutting force decreases and the workpiece surface quality decreases.

The relationship between rotation speed and surface roughness in the grinding process, that is, the influence of the rotation speed of the grinding wheel and the workpiece on the surface roughness of the workpiece is summarized as follows: 1. The higher the rotation speed of the grinding wheel, the more abrasive grains pass through the ground surface per unit time, and thus the smaller the roughness value of the workpiece surface. At the same time, the higher the rotation speed of the grinding wheel, the more likely it is that the propagation speed of the plastic deformation of the surface metal will be greater than the cutting speed, and the workpiece material will not have time to deform, resulting in a decrease in the plastic deformation of the surface metal, and the roughness value of the grinding surface will also decrease. 2. The effect of the workpiece rotation speed on the surface roughness is just the opposite of the effect of the grinding wheel speed. When the workpiece rotation speed increases, the number of abrasive grains passing through the ground surface per unit time decreases, and the surface roughness value will increase. 3. The lateral travel speed of the grinding wheel decreases, and the number of times each part of the workpiece surface is repeatedly ground by the grinding wheel increases, and the roughness value of the ground surface will decrease. On the contrary, the roughness value of the ground surface will increase. Workpiece surface grinding quality control and grinding wheel working principle: 1. The sand grains in the grinding wheel are randomly distributed, disorderly and uneven, and can be seen as thousands of sharp knives. During grinding, the cutting edge changes continuously and becomes blunt. The blunted grinding wheel continues to grind because the grinding force continues to increase. When the grinding force exceeds the bonding force of the binder, the abrasive grains will automatically fall off. This is called the "self-detachment" of the grinding wheel; the grinding process of the grinding wheel is to repeat this process. 2. Each part of the workpiece surface is repeatedly ground by the grinding wheel. The angle and direction of the scratch marks caused by the grinding wheel per unit area are regular, and the size and depth of the scratch marks are random and cannot be accurately measured. 3. The number of sliding and sliding force per unit area of the workpiece surface directly affect the roughness of the workpiece and the quality of the layout. The number of sliding is proportional to the sliding lines formed on the layout and inversely proportional to the roughness; the sliding force is proportional to the roughness. The surface roughness of steel-based workpieces is proportional to the roughness of the coating after electroplating. 4. The number of sliding frictions and the sliding force per unit area of the workpiece surface can be controlled by adjusting the grinding process.
