Product Description
Photo Chemical Milling 0.1mm to 1mm Thickness Metallic Encoder Disk For Precision Engineer
What is a Metallic Encoder Disk?
| A metallic encoder disk is a precision-engineered metal component used in optical and rotary encoders to convert rotational or linear motion into electrical signals. These disks feature precisely etched slots or patterns that allow sensors to detect position, speed, and direction — essential in automation, robotics, motor control, aerospace, and measuring systems. |  |
Materials We Use
We manufacture metallic encoder disks using high-quality materials to ensure stability, durability, and excellent corrosion resistance:
| Stainless Steel | Copper | Aluminum | Titanium |
Specifications of Etched Metallic Encoder Disk
| Thickness | 0.1mm – 1.0mm |
| Outer Diameter | 5mm – 300mm (customizable) |
| Etch Accuracy | ±0.01mm (According to the thickness) |
| Surface Finish | Matte / Bright / Passivated |
| Pattern Type | Slots, lines, code patterns, or custom designs |
Photo Chemical Milling Process
Our photo chemical milling (also known as photo etching) process uses photolithography and chemical etchants to remove selected metal areas with micron-level precision — no mechanical stress or burrs are produced. This method ensures sharp edges, consistent aperture sizes, and perfect pattern alignment, making it ideal for encoder applications that demand absolute accuracy.
Advantages of Our Photo Chemical Milling Technology
-
No burrs or deformation, maintaining optical accuracy
-
High repeatability for mass production
-
Fine details achievable — micro features down to 0.05mm
-
No tool wear or stress, unlike stamping or laser cutting
-
Quick prototyping & cost-effective for both small and large runs
