Advantages and disadvantages of dry polishers: explained with data and cases
In the field of industrial surface treatment, dry polishers have gradually attracted attention due to their unique working method. Today, we use real data and cases to give you a comprehensive understanding of its advantages and limitations. 1. What is a dry polisher? Simply put, a dry polisher is a surface treatment equipment that does not use water or abrasive fluid. It adopts the principle of physical grinding, and through high-speed horizontal rotation and planetary tumbling motion, the abrasive medium and the workpiece are in full contact without dead angles, achieving efficient polishing. 2. The three core advantages of dry polishers
1. Efficiency is greatly improved, and the yield rate is significantly improved
The case of a certain automobile parts factory is the most convincing:
The yield rate of traditional manual polishing of mirror workpieces is only 65%;
After switching to a dry polisher, the yield rate is directly increased to 92%;
The production capacity is also increased simultaneously, and more than 300 workpieces can be processed every day.
More importantly, the operation threshold is low - new workers can start work after one day of training, which greatly reduces the dependence on experienced polishers.
2. Significantly reduced costs and reduced environmental pressure
The actual calculation data of a hardware processing plant shows:
Consumables cost: 1 ton of walnut abrasive used by dry polishing machine can be used repeatedly for half a year, which saves more than 20,000 yuan in material costs each year compared with traditional grinding fluid;
Environmental protection cost: There is no need to treat polishing wastewater, and the annual environmental protection expenditure is directly reduced by 15,000 yuan.
The double cost reduction has a significant effect on improving corporate profits.
3. More stable quality and extremely low workpiece damage rate
In the processing of aluminum alloy parts in a precision instrument factory:
During manual polishing, the deformation rate of parts is as high as 20%, and corner bumps are frequent;
After switching to a dry polishing machine, the deformation rate dropped to less than 1%, and corner bumps were completely avoided.
For workpieces with high precision requirements, this stability is particularly important.
3. Limitations of dry polishers
Despite its outstanding advantages, dry polishers also have applicable boundaries:
Shape limitations: It is difficult to process special workpieces with deep holes and complex grooves inside;
Precision boundaries: If the workpiece requires extremely high surface finish, manual post-processing is still required.
4. Purchase suggestions
Before choosing a dry polisher, it is recommended to do two things:
Calculate the input-output ratio, and make a comprehensive assessment based on the costs of consumables, labor, and environmental protection;
Match the characteristics of the workpiece to confirm whether it meets the shape and precision requirements of your own products.
Only with precise matching can the equipment achieve maximum value.
