Modification and maintenance of grinding machinery
With many stone care customers gradually transformed into the flooring industry, art millstone flooring industry. Stone grinding machine is not suitable for floor grinding, mechanical need to upgrade:
1. Increase the machine speed control function and install the frequency converter.
2. Add dry grinding dust suction device. After the laying of industrial and commercial floors, the flatness of the stone is often less than that of the site. In the rough grinding stage, when the floor machinery is ground, it is often necessary to reduce the speed of the grinding disc to grind and carry out high standard leveling grinding. Low speed grinding, can reduce the floor off sand may, low speed grinding is rough grinding automatic repair needs. Furthermore, the floor grinding completely needs dry grinding, which is conducive to the improvement of grinding efficiency and cutting speed; it is conducive to environmental protection; floor curing mirror treatment process requirements.
At the same time, we should pay attention to the use requirements of the grinding machine: 1. The surface layer of concrete and red brick is modified or semi-modified, and it is necessary to make the concrete and red brick as close to its essence, compactness, hardness and hardness as glass.
2. Grind and smooth to make a good foundation for light transmission, reflection and imaging. How to grind here? Grinding mechanical grinding to determine, time control, speed control is very important. Whether it is step-by-step grinding or step-by-step grinding and the determination of the type and number of grinding pieces need to be determined.
3. Determination of flatness standard and detection method: is it horizontal or relatively flat. Here we generally speak relatively flat, level is very difficult, because a large area of the ground is different from a single piece of stone processing. The relative flatness standard is 2m straight edge side stand, and the distance from the lowest lying area in the middle is ≤ 2mm or less. The flatness detection method is to plug 1-2mm thick sheet or paper in the middle after the ruler is in contact with the ground, detect 10 points in zones, and take the average value.
