Title: Why Are Wet Polishing Machines More Popular? Dual Advantages of Cooling and Lubrication, Metalworking Surface Roughness as Low as Ra0.2μm

In the field of metal surface finishing, the polishing process directly determines product appearance and performance. Relying on the triple effects of cooling, lubrication and chip removal of liquid media, wet polishing machines have become the preferred equipment for high-end metal processing. Compared with the traditional dry polishing process, the surface quality is improved by 40% and the consumable life is extended by more than 2 times. This article combines industry data to explain the core advantages, selection points and application scenarios of wet polishing machines.

1. Core Differences Between Wet and Dry Polishing

 

Comparison Dimension	Wet Polishing Machine	Dry Polishing Machine
Cooling Effect	Liquid medium cools down rapidly, no thermal deformation of workpieces	Limited airflow cooling, local temperature reaches hundreds of degrees Celsius
Surface Quality	Chips are washed away instantly, no secondary scratches, Ra≤0.2μm	Easy to produce dust adhesion, surface roughness Ra≥0.8μm
Consumable Life	Abrasives are suspended evenly, uniform loss, 2x longer life	Abrasives are easy to block, high replacement frequency
Environmental Protection	Circulation filtration system, zero dust emission	Additional dust collection equipment required, still has dust pollution
Applicable Materials	Copper, aluminum, stainless steel and other thermally deformable metals	High-hardness metals, workpieces with low surface requirements

2. Detailed Explanation of Popular Model Parameters

As a wet polishing and wire drawing machine with a leading market share, its core configuration meets the needs of multiple industries:

1. Processing Range: Width 650mm-1650mm, thickness 1-80mm, suitable for flat plate parts;
2. Speed Adjustment: Abrasive belt linear speed 18m/s, feeding speed 2-11m/min, variable frequency adjustable;
3. Feeding Mode: Supports three modes: conveyor belt semi-magnet semi-vacuum, magnetic adsorption, and vacuum adsorption, suitable for workpieces of different materials (e.g., vacuum adsorption for stainless steel, magnetic adsorption for carbon steel).

3. Core Application Scenarios

1. Automotive Parts: Surface polishing of engine cylinder blocks and gearbox housings to remove processing marks and improve sealing performance;
2. Decorative Building Materials: Wire drawing and polishing of stainless steel cabinets and aluminum panel curtain walls to achieve decorative effects such as long straight grains and snowflake grains;
3. Medical Devices: Finishing of surgical instrument surfaces to ensure no burrs and no chemical residues;
4. Electronics Industry: Polishing of mobile phone middle frames and communication module shells to reduce surface roughness and improve coating adhesion.

4. Practical Precautions

1. Select Suitable Abrasives: Soft abrasives (e.g., aluminum oxide) for copper materials, hard abrasives (e.g., silicon carbide) for stainless steel;
2. Equipment Maintenance: Clean the water squeeze roller and spray water pipe daily, check the hydraulic system pressure weekly, and calibrate the feeding speed accuracy monthly.
