Confucius said, "A craftsman who wants to do his work well must first sharpen his tools." To complete any processing or assembly task, one must first be equipped with suitable and excellent tools. Hardware tools cannot be used without maintenance; doing so will shorten their lifespan. We will discuss the use and maintenance of pneumatic screwdrivers, a type of pneumatic tool. Pneumatic tools are mainly used for tightening and assembly. Major industries using them include automotive manufacturing, electronics, home appliances, auto parts production, equipment repair, and aerospace. Precision, reliability, and durability are the functional standards for pneumatic tools. The quality of rotary pneumatic tools depends on six aspects:
1. The performance of the built-in pneumatic motor (rotational power);
2. The metal materials and processing methods used in the transmission mechanism components;
3. The machining accuracy of the components and the assembly accuracy of the tool;
4. Innovation, optimization, and improvement in tool design and production;
5. Quality control;
6. Correct and reasonable use.
1. Proper Air Supply System: The intake air pressure at the tool inlet (not the compressor outlet pressure) is generally 90 PSIG (6.2 kg/cm²). Pressures that are too high or too low will damage the tool's performance and lifespan. The intake air must contain sufficient lubricating oil to adequately lubricate the pneumatic motor inside the tool (you can check for oil stains by placing a piece of white paper at the tool's exhaust port; normal operation involves oil stains). The intake air must be completely free of moisture; compressing air without an air dryer is inappropriate.
2. Do not arbitrarily disassemble tool parts before operation, as this will not only affect the operator's safety but also damage the tool. If the tool malfunctions slightly or fails to perform its original function after use, do not continue using it; inspect it immediately.
3. Regularly (approximately once a week) inspect and maintain the tool. Add grease to rotating parts such as bearings and add oil to the pneumatic motor.
4. When using any tool, always follow all safety regulations and operating instructions.
5. Use appropriate tools for your work. Tools that are too large can cause work-related injuries, while tools that are too small can easily be damaged.
