1. What is CNC Skiving?

CNC skiving is an advanced machining process that utilizes computer numerical control (CNC) technology to create precise and complex shapes in various materials. By rotating a cutting tool against a workpiece, CNC skiving efficiently removes material to achieve highly accurate dimensions and surface finishes. This method is especially beneficial for manufacturing components with intricate profiles, such as gears and splines.

2. How Does CNC Skiving Work?

CNC skiving operates by employing a skiving tool that features an array of cutting edges. The workpiece is securely mounted on a spindle that rotates it at high speeds. As the skiving tool advances linearly, it engages with the rotating workpiece, removing material in a controlled manner. This process allows for both axial and radial cutting, making it highly versatile for various applications.
The CNC aspect provides automation, enabling complex programming of cutting paths and speeds. As a result, manufacturers can achieve greater precision and repeatability compared to traditional methods, significantly reducing the potential for human error.
