Fluid polishing machine is a kind of processing equipment that uses semi-fluid medium containing abrasive to reciprocate through the surface of the workpiece under pressure to achieve deburring, chamfering and reducing roughness. Its core principle is to use the micro-cutting effect of abrasive particles on the surface of the workpiece in the flow.

First, the process flow

1. Workpiece clamping: Fix the workpiece to be processed on a special fixture to ensure that the abrasive flow channel is sealed, so that the abrasive can only flow according to the preset path.

2. Equipment setting: According to the workpiece material, initial state and target finish, set the appropriate processing pressure, abrasive flow rate and processing time.

3. Abrasive filling: The pre-selected fluid abrasive is loaded into the machine material cylinder.

4. Extrusion polishing: Start the equipment to allow the abrasive to repeatedly flow through the surface of the workpiece to be machined under high pressure.

5. Remove and clean up: After processing, remove the workpiece, remove the residual abrasive, and complete the surface inspection.

II. Precautions

1. Abrasive management: Abrasives need to regularly filter impurities and replenish new materials to ensure stable cutting force. Processing requirements of different precision need to correspond to abrasives of different mesh numbers and cannot be mixed.

2. Pressure control: The processing pressure must be set according to the structure of the workpiece, and the pressure of thin-walled parts or small holes should be appropriately reduced to prevent deformation of the workpiece.

3. Equipment sealing: Regularly check the seals of the cylinder and fixture to prevent abrasive leakage under high pressure, which will affect the processing effect and cause waste.

4. Workpiece cleaning: Before polishing, it is necessary to ensure that the surface of the workpiece is free of oil stains, iron filings and other debris to avoid hard particles mixed into the abrasive and scratching the processing surface.

5. Safety protection: When the equipment is running under high pressure, it must be completely shut down before opening the protective door or manual intervention to avoid high-pressure abrasive splashing.

Overall, the fluid polishing operation needs to focus on controlling the abrasive state, pressure parameters, and equipment sealing to ensure the consistency and stability of the processing quality.
