Surface Treatment

What is CNC machining parts surface treatment

CNC machining parts surface treatment refers to the process of improving the surface performance of parts by physical, chemical or electrochemical means. Its purpose is to improve the wear resistance, corrosion resistance, oxidation resistance, appearance and other properties of parts, and ensure the long-term reliability and stability of parts in high-intensity and complex environments. CNC machining has advantages in manufacturing precision, but there may be defects such as burrs and roughness on the surface of parts, so it needs to be further optimized through surface treatment process.

Polishing can make the surface smooth and mirror-like, suitable for high-end appearance requirements; sandblasting can improve surface roughness and enhance adhesion; anodizing and PVD coating can enhance corrosion resistance and extend the service life of parts; passivation prevents oxidation by forming a protective film. Combined with precision CNC machining, the surface treatment of stainless steel parts can effectively improve performance and is widely used in automotive, aviation, medical, electronics and other fields.

Brass CNC parts surface treatment services

Surface treatment of brass CNC parts can improve the appearance, corrosion resistance and wear resistance of parts. Common treatment methods include electroplating, polishing, sandblasting, oxidation, etc. Electroplating can provide brass parts with a variety of colors and glosses to increase aesthetics; polishing can make the surface smoother and enhance the visual effect; sandblasting can increase surface roughness and improve adhesion. These surface treatment processes are widely used in electronics, decoration, machinery and other industries to enhance the functionality and aesthetic value of products.

Application fields of CNC machining surface treatment

In the automotive parts industry, surface treatment improves the overall performance and service life of parts by enhancing their corrosion resistance, wear resistance and aesthetics. Combined with precision CNC machining, surface treatment methods such as sandblasting, polishing, anodizing, PVD coating, etc., can not only improve the appearance of parts and make them more visually attractive, but also effectively resist erosion from the external environment, reduce wear and extend the durability of parts. These processing technologies are widely used in the fields of automotive engines, chassis, body trims and interior parts, meeting the automotive industry’s strict requirements for high quality, high precision and high performance. Through surface treatment, automotive parts can improve functionality while meeting consumers’ multiple demands for appearance and durability, further enhancing the market competitiveness of products.

In the aerospace industry, surface treatment is a key technology to ensure the reliability and performance of parts. Combined with precision CNC machining, surface treatment methods such as anodizing, PVD coating, spraying and polishing can effectively improve the corrosion resistance, wear resistance, high temperature resistance and oxidation resistance of parts, meeting the high requirements of the aerospace field for extreme working environments. These treatments not only extend the service life of parts, but also enhance their structural strength and fatigue resistance, and reduce maintenance and replacement costs. For example, anodizing can improve the corrosion resistance of aluminum alloy parts, PVD coating provides wear protection, and polishing treatment improves surface smoothness. Through high-precision CNC machining and advanced surface treatment technology, aerospace companies are able to produce high-reliability and high-safety parts to ensure the long-term stable operation and safety performance of aircraft.

In the consumer electronics industry, surface treatment technology plays a vital role in improving product appearance, durability and performance. Combined with precision CNC machining, surface treatment methods such as anodizing, sandblasting, polishing, PVD coating and spraying can effectively improve the corrosion resistance, wear resistance and anti-fingerprint stains of electronic equipment parts, and enhance the visual appeal and feel of the product. For example, anodizing is often used for aluminum alloy shells of mobile phones, tablets and other devices, giving them a rich color selection and greater durability; PVD coating can provide metallic luster and wear resistance. Surface treatment not only enhances the functionality and aesthetics of consumer electronic products, but also reduces wear and scratches during use, extends the service life of the product, enhances the consumer experience, and meets the industry’s requirements for high quality and high precision.

In the medical device industry, surface treatment is a critical step to ensure product performance and safety. Precision CNC machining combined with advanced surface treatment technologies such as passivation, anodizing, PVD coating and polishing can significantly improve the corrosion resistance, wear resistance and biocompatibility of the device. Passivation treatment can enhance the antioxidant capacity of metals such as stainless steel, prevent bacterial growth, and ensure the hygiene and safety of instruments during use; anodizing and PVD coatings improve surface hardness and scratch resistance, increasing durability. Through these surface treatments, it not only improves the functionality of medical devices, but also improves the stability and reliability of the product, meets the industry’s requirements for high precision and high standards, provides guarantee for the long-term use of medical equipment, and thereby improves the treatment effect of patients. and security.
