Description

This precision CNC machined Hirth coupling disc is engineered for high-accuracy positioning and high-torque transmission applications. Featuring a radial face tooth design, it provides exceptional repeatability, rigidity, and load capacity compared to traditional spline or keyway connections.

Manufactured from high-strength alloy steel or stainless steel, each component undergoes advanced CNC turning, milling, and precision gear machining processes, followed by optional heat treatment such as quenching, carburizing, or nitriding. This ensures excellent wear resistance, dimensional stability, and long service life under demanding operating conditions.

The face-to-face tooth engagement design allows for precise angular positioning and secure mechanical locking, making it ideal for applications where repeatability and rigidity are critical. The finely machined tooth profile ensures uniform load distribution across the contact surface, significantly improving torque transmission efficiency and minimizing backlash.

This type of coupling disc is widely used in CNC rotary tables, 5-axis machining centers, aerospace positioning systems, and robotic joint mechanisms, where micron-level positioning accuracy and high structural stiffness are required.

With full customization capabilities, we support various sizes, tooth geometries, tolerances, and surface treatments based on customer drawings or technical requirements. From prototype to mass production, strict quality control processes—including CMM inspection and gear profile measurement—ensure consistent precision and performance.
