Revolutionizing Precision in CNC Milling and Lathe Machines

In the pursuit of high-precision manufacturing, the **optical linear scale** has emerged as a critical tool, significantly enhancing accuracy in CNC machines such as milling and lathe systems. Our advanced optical scales are designed to offer superior positioning accuracy and reliable performance over long periods, even in challenging environments.

Unlike traditional systems that rely on a four-pair LED design, our optical scales use a **single light source** and a **large-area receiving module**, which provides significant advantages in long-term stability, durability, and resistance to environmental contaminants. This reduces maintenance costs and downtime, resulting in higher operational efficiency.

Innovative Technology in Our LS/LE Series Optical Linear Scales

The **LS/LE series incremental optical linear scales** use a self-developed **infrared LED light source** paired with precision optical lenses to create a large-area parallel light. This light passes through a scanning grating and the optical scale, creating a periodic signal at the receiving module. This output signal precisely matches the pitch of the optical scale grating, ensuring high-quality signal output.

Key features include:

• Single LED Source: Our self-designed single LED source offers superior light parallelism and uniform light intensity compared to multi-LED systems, eliminating the desynchronization issues found in traditional four-pair LED systems due to aging components.
• Large-area Photodiode Receiver: The receiving module is equipped with six large-area photodiodes, significantly enhancing signal strength and interference resistance, allowing reliable performance even in harsh environments.
• High Signal Processing Speed: A proprietary sine-wave signal subdivision chip processes data purely via hardware, enabling high-speed signal output up to 2.5 MHz, ideal for high-speed CNC operations.

Unmatched Interference Resistance and Durability

• High Interference Resistance: Our signal processing boards feature a four-layer design with differential processing in the front-end circuitry, offering interference resistance up to 2200V. This makes our optical scales perfect for long-distance signal transmission, enhanced by the protective double-shielded cables encased in a robust metal cover. (Patent No: ZL200820044310.3)
• Vibration and Wear Resistance: The scale head features high-quality imported bearings and a specialized spring structure, ensuring reliable performance even during heavy cutting operations. The die-cast aluminum alloy head further enhances corrosion resistance, while the thicker body of the scale ensures accuracy when installed on machines.
• IP54 Water and Dust Resistance: The scale head is designed with waterproofing capabilities, making it suitable for depths of up to two meters. The entire scale unit achieves an IP54 rating, ensuring long-term durability in various environments.

Easy Maintenance and Full Traceability

Our optical linear scales are designed with easy maintenance and traceability in mind. Each component, from the body to the signal cable, can be individually disassembled, reducing repair costs and downtime. Additionally, every scale undergoes stringent aging and interference tests, accompanied by a precision certification report to ensure full traceability and reliability.
