Custom CNC Turned Parts Brass Anodized Aluminum High Precision CNC Lathe Part

CNC turning is a common metal processing method used to produce various shaft, disc and sleeve parts. After CNC turning, the surface treatment and use of parts are key steps to ensure their performance and life.

Surface treatment:
Deburring: After turning, parts usually have burrs, which need to be removed by manual deburring, mechanical deburring or chemical deburring.
Cleaning: Use cleaning agents or ultrasonic cleaning equipment to remove oil, cutting fluid and impurities on the surface of parts.
Descaling: For materials that are easily oxidized, such as aluminum, steel, etc., it is necessary to remove the surface oxide scale, which is usually completed by pickling, alkali washing or mechanical methods.
Polishing: Improve the surface finish of parts, reduce surface roughness and improve appearance quality through polishing and other methods.
Coating: In order to improve wear resistance, corrosion resistance or other special properties, coatings can be applied to the surface of parts, such as galvanizing, chrome plating, anodizing, spraying, etc.
Heat treatment: For some parts, in order to achieve specific hardness and strength, heat treatment is required, such as quenching, tempering, surface hardening, etc.
Rust prevention: Rust prevention treatment is performed on metal parts that are prone to rust, such as anti-rust oil, phosphating treatment, etc.

Use:
Assembly: CNC turned parts are usually used to assemble other mechanical products or equipment, such as automobiles, aircraft, mechanical equipment, etc.
Functional parts: Directly used as functional parts, such as shafts, gears, screws, nuts, bearing sleeves, etc.
Repair and replacement: Used as replacement parts during equipment maintenance and repair.
Product processing: As part of the mold or fixture, it is used for mass production of products.
Quality control: During the manufacturing process, the accuracy and quality of CNC turned parts directly affect the performance of the final product, so strict quality control is required.
When using CNC turned parts, pay attention to the following points:

Correct installation: Ensure that the parts are installed correctly to avoid damage or performance degradation caused by improper installation.
Environmental adaptability: Consider the working environment of the parts, such as temperature, humidity, corrosiveness, etc., and select appropriate materials and surface treatment methods.
Regular inspection: Regularly check the wear and damage of parts during use, and perform maintenance or replacement in time.
Lubrication: For moving parts, regular lubrication is required to reduce wear and extend service life.
