The working contents of the pre-treatment process of the high quality metal grinding disc mainly include: sanding substrate finishing, substrate cleaning, abrasive cleaning and solder particle size screening.
The pre-treatment process in the production of high quality metal grinding discs is the most meticulous work of the brazing workers. The principle of doing this work is: all the workpieces to be worked (base, abrasive, etc.) are clean and dust-free, the sanding substrate is active, brazing The material size is uniform.
Among them, the finishing work of the upper sand substrate is completed by a manual sand blasting machine, which is generally operated by one person. It takes 8 hours to complete the finishing of 500 high quality metal grinding discs and share 8 working hours.
The substrate cleaning work is done by a manual ultrasonic cleaner, usually by one person. It takes 4 hours to complete the cleaning of 500 high quality metal grinding discs and share 4 working hours.
Abrasive cleaning and solder particle size screening work is done manually by one person. It takes 2 hours to complete the 500 high quality metal grinding disc materials and shares 2 working hours.
