Example Embodiment
[0069] Example 1
[0070] A workpiece made of 3D printed titanium alloy is put into polishing equipment for grinding. The roughness Ra before grinding is 10-11. Specific operations can be:
[0071] Open the upper cover of the equipment and put SiO into the polishing barrel according to the gravity ratio 2 20 parts of granules and 80 parts of water; and then add 3 parts of rust inhibitor according to the volume ratio. The rust inhibitor is polyethylene glycol PEG-400.
[0072] Mount the 3D printed titanium alloy workpiece on the fixture, and fix the fixture on the connecting shaft with screws.
[0073] Cover the upper cover, start the agitator motor and the workpiece rotation motor, set the speed of the agitator motor to 200r / min, and the rotation speed of the workpiece to 60r / min.
[0074] Run for 25 minutes, stop both motors. Take out the 3D printed titanium alloy workpiece and measure the surface roughness Ra of 6-8.
Example Embodiment
[0075] Example 2
[0076] A workpiece made of 3D printed titanium alloy is put into polishing equipment for grinding. The roughness Ra before grinding is 10-11. Specific operations can be:
[0077] Open the upper cover of the equipment and put SiO into the polishing barrel according to the gravity ratio 2 20 parts of granules and 80 parts of water; then add 3 parts of rust inhibitor and 2 parts of lubricant according to the volume ratio. SiO 2 The average particle diameter is 50-60 nanometers, the rust inhibitor is polyethylene glycol PEG-400, and the lubricant is ethylene glycol and sodium phosphate.
[0078] Mount the 3D printed titanium alloy workpiece on the fixture, and fix the fixture on the connecting shaft with screws.
[0079] Cover the upper cover, start the agitator motor and the workpiece rotation motor, set the speed of the agitator motor to 200r / min, and the rotation speed of the workpiece to 60r / min.
[0080] Run for 20 minutes, stop the two motors. Take ...
