Product Introduction:

This precision metal encoder disc features a fine pitch optical disc structure for high accuracy encoding applications. The fine pitch disc allows for improved resolution and signal precision, making it suitable for advanced encoder systems. As a reliable encoder disc, it ensures stable performance in demanding environments.

Applications:

Fine pitch encoders, motion control systems, robotics, precision equipment, automation devices

In the rapidly evolving landscape of industrial automation, robotics, and medical technology, the demand for Precision Metal Encoder Discs is higher than ever. Engineers are constantly seeking components that offer finer pitch structures, higher durability, and tighter tolerances. However, finding a manufacturing partner who can navigate the complexities of these requirements is often a challenge.

At NKEYTO, we position ourselves not just as a supplier, but as a comprehensive manufacturing partner. We understand that no single manufacturing process fits every application. That is why our facility integrates Chemical Etching, Laser Cutting, and CNC Machining under one roof. This versatility allows us to engineer the ideal Optical Fine Pitch Structure for your specific needs, balancing cost, speed, and precision.

Our Core Technologies: A Hybrid Approach
To deliver a true one-stop solution, we leverage the strengths of three distinct manufacturing technologies. By offering this range, we can objectively recommend the best process for your project rather than forcing a "one size fits all" approach.

1. Chemical Etching: The Gold Standard for Thin Metal
For high-volume production of thin, flat Precision Metal Encoder Discs, Chemical Etching is our primary recommendation.

• Why we use it: It is a stress-free, "cold" process that creates burr-free edges. This is critical for Optical Fine Pitch Structures where even a microscopic burr can scatter light and ruin signal quality.
• Best for: High-resolution encoder discs, complex mesh patterns, and thin metal shims.

2. Laser Cutting: Speed and Flexibility
For thicker materials or rapid prototyping where tooling costs need to be avoided, our laser capabilities are essential.

• Why we use it: It offers incredible speed for cutting outer profiles and mounting holes.
• Best for: Thicker metal discs (>1mm), rapid prototyping, and structural components where extreme optical edge quality is less critical.

3. CNC Machining: Heavy-Duty Precision
When a component requires complex 3D features—such as counterbores, threaded holes, or specific surface finishes—CNC machining is the answer.

• Why we use it: It provides the highest dimensional accuracy for heavy-duty parts.
• Best for: Encoder hubs, mounting flanges, and thick rotors that require both optical slots and mechanical machining.

Process Selection Guide
To help our clients choose the right path for their Precision Metal Encoder Disc, we have compiled a comparison of our capabilities:

Engineering "Fine Pitch" Structures
The core of our expertise lies in creating Optical Fine Pitch Structures. As encoders become smaller and more precise, the slots on the disc must be etched closer together.

Our chemical etching process allows us to achieve:

• Slot Widths: Down to 0.1mm.
• Pitch Accuracy: Maintaining consistent spacing across the entire disc radius.
• Concentricity: Ensuring the optical pattern is perfectly aligned with the mechanical center (±0.02mm).

This level of precision ensures that whether we use etching for the pattern and laser for the profile, the final Precision Metal Encoder Disc performs flawlessly in your motion control system.

Materials and Finishes
We work with a wide range of materials suitable for diverse environments:

• Stainless Steel (SUS304, SUS316): For corrosion resistance and durability.
• Aluminum: For lightweight applications requiring high speed.
• Copper & Brass: For specific electrical conductivity needs.
• Titanium: For high-strength, biocompatible medical applications.

We also offer secondary services such as passivation (to enhance corrosion resistance), nickel plating, and black oxide coating to reduce light reflection.

Frequently Asked Questions (FAQ)

Q1: Which process is best for a high-resolution encoder disc?
A: For high resolution, Chemical Etching is superior. It allows us to create the Optical Fine Pitch Structure required for precise feedback without the heat distortion associated with laser cutting or the mechanical stress of stamping.

Q2: Can you combine processes on a single part?
A: Yes. This is a key advantage of our one-stop facility. We often use Chemical Etching to create the fine slot pattern on a thin metal disc, and then use Laser Cutting or CNC to machine the outer diameter and mounting holes. This optimizes both cost and performance.

Q3: Do you handle prototyping?
A: Absolutely. We support our clients from the R&D phase through to mass production. For prototypes, we can utilize laser cutting for speed, and then transition to chemical etching for the final production run to ensure the highest quality.

Q4: What is the minimum feature size you can produce?
A: Using our advanced chemical etching capabilities, we can produce features and slot widths as small as 0.1mm, allowing for extremely high line counts on small diameter discs.
