عربى1. Clean the machine frequently, especially the wax dust in the chassis to prevent precipitation.
2. Pay attention to whether there are sundries or yarn entanglement under the pad of the polishing machine, which will increase the resistance and the sound of the motor, causing the belt to break.
3. The polishing machine polishes at high speed, and it is strictly forbidden to polish on the wooden floor or plastic PVC floor.
4. When polishing hard ground, pay attention to the uneven ground, and the ground slope is 2%.
5. Avoid squeezing, pulling, excessive bending and abrasion of wires, as well as damage by heat, oil and sharp objects.
Polishers make noise during grinding and polishing. The polishing machine vibrates violently and makes noise under the action of unbalanced force. At the same time, noise has a certain impact on Desktop grinder Factory work mood, work efficiency and workpiece effect.
Only then can we take steps to avoid the noise and solve the problem.
The operator can try to simplify the inherent working principle diagram, explore and analyze the vibration of a single abrasive, especially the grinding head, and finally come to the conclusion that the grinding width and the speed of the polishing head are the direct factors affecting the abrasive particles. noise.
Therefore, vibration is the source of noise, which is a dynamic instability phenomenon, especially in surface polishing machine polishing.
At present, the polishing machine is mainly used for polishing the surface of aluminum, iron, copper, steel and other materials, and has the characteristics of high efficiency and good effect. Today, the editor of Jianguang Machinery would like to talk to you about the factors that affect the polishing quality of the polishing machine?
First, because mechanical polishing is mainly done by hand, polishing technique is still the main factor affecting polishing quality. In addition, it is also related to the mold material, the surface condition before polishing and the heat treatment process. High-quality steel is a prerequisite for good polishing quality. Polishing is often difficult if the surface hardness of the steel is uneven or there are differences in properties. Various inclusions and pores in the steel are not conducive to the polishing of the pipe polishing machine.
The effect of different hardness on polishing process. Grinding difficulty increases as hardness increases, but roughness decreases. Due to the increase in hardness, the polishing time required to achieve lower roughness also increases accordingly. At the same time, as the hardness increases, the possibility of overpolishing decreases.
The effect of workpiece surface conditions on the polishing process. Steel can be damaged by heat, internal stress or other factors during cutting. Improper cutting parameters will affect the polishing effect. EDMed surfaces are more difficult to grind than normal machined or heat treated surfaces. Therefore, precision EDM should be used before the end of EDM, otherwise a hardened thin layer will form on the surface.
If the EDM finishing gauge is not properly selected, the depth of the heat affected layer can reach 0.4mm. The hardness of the hardened layer is higher than that of the substrate, so it must be removed. Therefore, it is necessary to increase the rough grinding process to remove the damaged surface layer to form an average rough metal surface, which provides a good foundation for the polishing process of the round tube polishing machine.
The above are the main factors that affect the polishing quality of the polishing machine. I hope to help you understand more about this knowledge.
