Roughness control:
Ingrinding wheelsthe same conditions
1. The faster the speed of the plate roller (linear speed), the lower the surface roughness.
2. The faster the rotation speed of the grinding wheel, the greater the roughness.
3. The greater the pressure of the grinding wheel, the greater the roughness.
In many cases, the speed of the grinding machine's plate roller can be greatly increased, and the rotation speed of the grinding wheel can be reduced to a very low level, or even rotated by the plate roller. In this case, grinding can be used for polishing. If the anti-oxidation measures of the plate roller are well done, it can go directly to electric engraving. This type of plate is also beneficial for the combination of copper and chromium and for printing to prevent wire drawing.
Grinding pattern control:
The contact surface between the grinding wheel and the plate, the more it deviates from the center of the grinding wheel (diameter line), the lower the surface roughness, and the pattern of the chips produced is beneficial for preventing wire drawing. See the figure below:
Additionally, from the image, it can be analyzed that the chip angle at the contact surface of the grinding wheel's inner hole and the plate roller is better. It is recommended that when finishing with the grinding machine, the inner hole should face outward. See the figure below:
It is recommended to use the environmentally friendlygrinding wheelyellow3000#, features:a. Odorless, formaldehyde-free, harmless to employees' health;
b. Super wear-resistant, can reach more than1.8
times that of ordinary grinding wheels;c. Stable process, no scratches.d. Anti-dry, extremely long storage time, ordinary grinding wheels are prone to cracking after being stored for a long time with low moisture.The overall cost performance is extremely high. A certain factory used traditional
grinding wheels every year1400
pieces, and after using the yellow environmentally friendlyit was recorded as
800, features:pieces, receiving high praise from the company owner. Another manufacturer used Shijiazhuang grinding wheels in the first month, and after switching to yellow in the second month, feedback indicated that one grinding wheel lasted almost24hours, whereas previously, features:more than 8hours would require replacement. Overall consumption was reduced by half compared to the first month. The workshop supervisor highly praised it.Due to its wear resistance, the frequency of grinding wheel replacements was reduced, and there were no scratches, which alleviated the labor intensity of employees and was welcomed by them!, features:However, due to its wear resistance, if the grinding wheel is not flat, it will take longer to level it. It is recommended to use the following two auxiliary devices to facilitate flattening and leveling.Continue to follow the WeChat public account of Maituo Technology for more technical articles and sharing!小时,原来8个多小时基本就要更换,整体消耗比第一个月减少一半。车间主管高度赞扬。
因为耐磨所以减少了砂轮更换次数,并且没有划伤,减轻员工劳动强度,得到员工的欢迎!
但因为耐磨,如果砂轮没有粘平的情况下,整平起来就比较慢,推荐使用以下两款辅助设备。利于粘平和整平。
