What is the key to the polishing machine?
The polishing machine is the most important operation to obtain the maximum polishing rate, so as to remove the damaged layer of polishing production. At the same time, the polishing damage layer does not affect the final observation of the tissue, and does not lead to the wrong organization. The former requires the use of coarse abrasives to ensure that the polishing rate greatly eliminates the polishing damage layer, but the depth of the polishing damage layer; the latter requires the use of the best materials, so that the polishing damage layer is shallow, but the polishing rate is low.
The hardness increases with the increase of hardness, but the surface roughness decreases after polishing. Due to the increase of hardness in order to achieve the required polishing time corresponding to the low growth roughness. At the same time, the possibility of high hardness, polishing off the corresponding reduction.
Polishing machine structure is simple, still need to use correctly, do daily maintenance, should pay attention to the following points in the use of. Continuous working time is too long, the polishing machine, polishing wheel friction temperature is high, easy to burn leather surface. The work roll surface should be clean before and after polishing, waxing, and keep the roller surface smooth and clean. Use proper feed roller pressure control to avoid too much resistance, electric heating is easy to burn. Good lubrication of the transmission chain of the rotation part, to maintain accurate and reliable transmission.
