Custom CNC machining of optical equipment parts involves strict requirements for high precision and surface finish, especially when processing components like optical lenses, prisms, lens holders, brackets, etc. Parts for optical equipment usually require stable material performance, high accuracy, and smooth, flawless surfaces to ensure the imaging quality and performance of the optical system. Below are the key points for custom machining optical equipment parts:

1. Material Selection

Commonly used materials for optical equipment parts include:

• Aluminum alloy: Frequently used for lens holders and brackets due to its lightweight and ease of machining, and it can undergo anodizing to enhance durability.
• Stainless steel: Suitable for parts that require strength and corrosion resistance.
• Titanium alloy: Used where lightweight and high strength are necessary.
• Optical glass: Used for prisms, lenses, and other components requiring optical performance.
• Plastics: Such as PMMA (acrylic) or PC (polycarbonate), widely applied in lightweight and cost-effective optical elements.

2. Machining Precision

The machining of optical equipment parts typically requires extremely high dimensional accuracy and surface finish. Five-axis machining is often used to process these complex 3D shapes and curved surfaces. Surface roughness usually needs to reach micron levels to ensure accurate refraction and reflection of light.

3. Surface Treatment

• Anodizing: For aluminum alloy parts, this enhances corrosion resistance and surface hardness, while also providing a matte or glossy finish.
• Electroplating: Used for stainless steel or copper parts to enhance surface wear resistance and corrosion resistance.
• Sandblasting: Commonly applied to reduce surface reflection, especially in optical devices where light reflection needs to be minimized.

4. Functional Requirements

The functional requirements for optical equipment parts include precision alignment, stability, and vibration resistance. These components often need to have complex geometries to allow the installation and securing of various optical elements.
