Methods to Improve the Efficiency of Precision Component Processing

In the processing of non-standard equipment parts, common issues such as accelerated tool wear, poor surface integrity, and difficulties in chip removal can significantly impact the quality, production cycle, and processing costs of precision components. These challenges are especially evident when working with materials like stainless steel. By analyzing these difficulties based on metal technology, metal cutting, and the principles of non-standard equipment part processing, effective drilling, reaming, and boring techniques for stainless steel have been developed.

Key Issues in Precision Processing

China's machinery manufacturing industry has traditionally faced limitations due to technological constraints and a shortage of skilled talent, making it difficult to compete with large companies in Europe and the U.S. in terms of technological innovation and product development. However, with the influx of foreign capital and increased industry competition, domestic machinery component processing has seen increased investments in independent development. This has led to significant advancements, particularly in the field of precision measuring instruments. For example, the successful development of a 2-meter CNC gear measuring instrument in China has become highly competitive on the international stage.

Additionally, foreign technology has greatly benefited domestic machining companies. Today, many domestic non-standard equipment part manufacturers have introduced advanced precision machining equipment from well-known foreign brands, including those from Japan and Germany. This foreign assistance has played a crucial role in improving the precision and surface quality of the Products produced.

Methods to Enhance Processing Efficiency

Non-standard equipment part processing requires ultra-smooth surfaces and high precision, which in turn demand tools with long Service lives. The wear of cutting tools directly affects the quality of the processed surfaces. If a tool is worn, the surface quality of the workpiece will degrade. Diamond tools, for example, have exceptionally long service lives and experience slow wear even under high-speed cutting conditions. In ultra-precision cutting, cutting speed is not constrained by tool life, which differentiates this approach from standard cutting practices.

The selection of cutting speed in non-standard equipment part processing is often based on the dynamic characteristics of the ultra-precision machine tool and cutting system. The optimal cutting speed is typically the one that minimizes vibration, as this results in the lowest surface roughness and the highest quality machining. Achieving high-quality surfaces is a key goal in non-standard equipment part processing. Using high-quality ultra-precision machine tools with excellent dynamic characteristics and low vibration allows for higher cutting speeds, ultimately improving both processing efficiency and product quality.

Choosing the right cutting parameters is also critical for achieving the best results. This includes selecting appropriate cutting tool angles, cutting speeds, cutting depths, and feed rates. Based on past experience, it is known that when machining ductile materials, using tools with larger rake angles can effectively reduce the formation of built-up edges (BUE). A larger rake angle reduces cutting forces, minimizes deformation, and shortens the contact length between the tool and the chip, thereby reducing the likelihood of BUE formation.

Finally, the use of high-precision machines plays a significant role in improving processing efficiency. Ultra-precision machine tools with good dynamic properties, low vibration, and the ability to handle higher cutting speeds are essential. These tools allow for faster cutting speeds without compromising surface quality, improving both productivity and the overall quality of the parts produced.

Conclusion

To improve the efficiency of precision component processing for non-standard equipment parts, manufacturers must optimize cutting parameters, select high-quality tools, and invest in advanced machining equipment. By focusing on these aspects, manufacturers can significantly increase productivity while ensuring high precision and surface quality. This approach not only reduces production costs but also enhances the competitiveness of products in the global market.
