A micro-porous nozzle processing method, characterized by including the following steps:
1. On the grinding machine, perform nozzle head grinding; inspect the workpiece before grinding to ensure the dimensions meet requirements.
2. Micro-hole drilling with nozzle, threading a workpiece through a silver wire on an internal hole machining machine, applying abrasive paste to the wire, and using ultrasonic processing for finishing. The diameter of the wire is 0.015mm, and the abrasive paste grade is 320.
3. Internal cone surface grinding: Using brass needles, abrasive paste, and ultrasonic technology to grind the internal cone surface of the holes, with the angle of the needle tip matching the internal hole face.
4. Cleaning: After the internal cone surface of the workpiece is machined, clean the workpiece using a 36-water wash for three hours, followed by a three-hour water wash. Then, secure the workpiece on a cleaned fixture and use high-pressure air to blow for three minutes.
5. Aperture Inspection: Utilizing a dedicated inspection device, automatically checks the aperture of the workpiece, primarily for roundness and dimensional accuracy.
6. CNC Grinding: Uses a CNC grinding machine for workpiece polishing, no grinding paste is required during the process, but coolant is necessary.
7. External Grinding, on an external grinding machine, grind the outer circle of the workpiece using a 300 grit abrasive膏.
8. Machining of the front bore of the workpiece using special needles made from titanium and 300 grit abrasive paste. The needle rotates in the opposite direction to the workpiece during the machining process.
9. Nylon wire grinding involves processing the inner hole and transition section of the workpiece. This is done using nylon wire with a diameter of 12-35um and abrasive paste with a grain size of 300, all on a machine.
10. Brush grinding is performed using a brush and a 300 grit abrasive paste to smooth the surface of the workpiece's front end.
11. State-of-the-art surface treatment
12. Clean parts, final inspection.
