Differences Between Dry and Wet No.4 Finished With Belt Grinding and Brushing Machine

31 Jul.,2025

 

In the metal surface treatment industry, dry and wet belt grinding processes each have their own advantages and are suited for different production needs. Here are the key differences between the two:

  1. Grinding Method

  • Dry Grinding: Utilizes dry sanding belts without liquid cooling. Suitable for general stainless steel plates, aluminum, and other metals. The equipment is relatively simple in structure, with lower maintenance costs.

  • Wet Grinding: Involves spraying coolant (usually water) during the grinding process, effectively reducing friction heat between the sanding belt and the metal surface. This prevents material damage caused by excessive heat, making it ideal for applications requiring higher surface quality or deeper texture effects.

  1. Surface Finish

  • Dry Grinding: Produces a relatively rougher surface texture, suitable for workpieces that do not require high-precision finishes.

  • Wet Grinding: Due to water's cooling effect, the surface is smoother and glossier, making it particularly suitable for high-end decorative panels, kitchenware, and household appliances.

  1. Grinding Head Pressure and Processing Speed

  • Wet Grinding: The cooling effect of water significantly reduces temperature, allowing for higher grinding head pressure. This enhances cutting performance, speeds up processing, and improves production efficiency.

  1. Dust Control and Environmental Impact

  • Dry Grinding: Without water cooling, dry grinding generates more dust, requiring stronger dust collection systems to maintain cleanliness.

  • Wet Grinding: Coolant effectively suppresses dust dispersion while carrying away metal debris, helping to keep the work environment clean.

  1. Equipment Maintenance

  • Dry Grinding: Relatively simple and suitable for businesses seeking cost-effectiveness and quick deployment.

  • Wet Grinding: Requires an additional coolant circulation system with regular maintenance. However, it delivers superior results for demanding surface treatment needs.
