Tungsten ejecting needle polishing is a treatment method that removes the rough part of the tungsten ejecting needle surface by grinding, polishing and other means to improve its smoothness and corrosion resistance. The following are the specific steps of tungsten ejecting needle polishing:
I. Preparation stage
1. Check the surface of the tungsten ejecting needle: Before polishing, it is necessary to check whether the surface of the tungsten ejecting needle is clean, free of impurities, oil stains, etc. These impurities and oil stains will affect the polishing effect and the quality of the tungsten ejecting needle.
2. Select suitable polishing materials: Select suitable polishing materials according to the material and polishing requirements of the tungsten ejecting needle. Commonly used polishing materials include diamond polishing agent, aluminum oxide polishing agent, silicon carbide polishing agent, etc.
3. Prepare polishing tools: Select suitable polishing tools, such as polishing machines, grinders, manual grinding tools, etc.
II. Rough grinding stage
1. Clamp the tungsten ejecting needle: Clamp the tungsten ejecting needle on the polishing tool to ensure that it is firmly fixed to prevent accidents during the polishing process.
2. Rough grinding: Use coarse-grained sandpaper or aluminum oxide polishing agent to rough grind the surface of the tungsten ejecting needle. The purpose of rough grinding is to remove the deeper scratches and rough parts on the surface of the tungsten ejecting needle, making it relatively smooth.
3. Cleaning: After the rough grinding is completed, use a cleaning agent to clean the polishing materials and impurities on the surface of the tungsten ejecting needle to ensure the effect of the next fine grinding.
III. Fine grinding stage
1. Clamp the tungsten ejecting needle: Clamp the tungsten ejecting needle on the polishing tool again.
2. Fine grinding: Use fine-grained sandpaper or silicon carbide polishing agent to fine-grind the surface of the tungsten ejecting needle. The purpose of fine grinding is to further smooth the surface of the tungsten ejecting needle and remove the marks left after rough grinding.
3. Cleaning: After the fine grinding is completed, use a cleaning agent again to clean the polishing materials and impurities on the surface of the tungsten ejecting needle.
IV. Fine grinding stage
1. Clamp the tungsten ejecting needle: Clamp the tungsten ejecting needle on the polishing tool again.
2. Fine grinding: Use extremely fine-grained sandpaper or diamond polishing agent to fine-grind the surface of the tungsten ejecting needle. The purpose of fine grinding is to make the surface of the tungsten ejecting needle smoother and more delicate, achieving the required accuracy and appearance. 3. Cleaning: After finishing the fine grinding, use the cleaning agent for the last time to clean the polishing materials and impurities on the surface of the tungsten ejecting needle.
V. Inspection stage
1. Check the surface of the tungsten ejecting needle: After polishing, it is necessary to check whether the surface of the tungsten ejecting needle reaches the expected smoothness and precision. If scratches, rough parts or other problems are found, further processing or rework is required.
2. Check the size: During the inspection process, it is also necessary to check whether the size of the tungsten ejecting needle meets the requirements, such as length, diameter, etc. If there is a size deviation, it is necessary to make corresponding adjustments or replacements.
3. Check the cleanliness: Make sure that the surface of the tungsten ejecting needle is clean and free of impurities to avoid affecting the performance.
VI. Ending stage
1. Packaging: Pack the processed tungsten ejecting needle to protect its surface from scratches or contamination.
2. Record: Record the relevant data and processing methods during the polishing process for future reference and handling of similar problems.
3. Delivery: Deliver the processed tungsten ejecting needle to the customer or store it in the warehouse for standby.
In short, the process of tungsten ejecting needle polishing requires multiple steps, and each step needs to be carefully operated and checked to ensure that the final polishing effect and quality meet the requirements. At the same time, safety issues need to be paid attention to during the processing, such as using appropriate tools and materials, avoiding dust and noise, etc.
