The process to hob timing pulleys is a fast and accurate method of cutting toothed parts. The exact speed, tool profile and angle of the hob and part contribute to the ultimate profile and tooth count of the product.
Here we see an AT10, 40 tooth timing pulley being hobbed from aluminum stock. As both the tool and part turn, the machine moves the hob along the length of the part. Hobbing requires both the hobbing tool and the part being cut, to rotate in a synchronized motion.
As the tool is moved along the length of the part, it removes material slowly as it passes across the material, creating the form of the tooth.
To complete the part, the tool will have to take 2-3 passes to reach the exact dimensions required. The number of passes, speed of the machine, and total process time is determined by the exact pitch, tooth count, and component material.
Timing Pulley's are machined from either aluminum, steel, stainless steel or plastic. Onvio's pulleys are produced exactly to your required configuration.
