Machining's Most Difficult Chamfer | Automatic Part Finishing

What is a Blended Chamfer?

This video shows a great execution of our precision. Our programming and compliant tech allow us to create targeted chamfers when the finish isn’t necessary for the whole part. We are also able to blend overlapping chamfers and avoid a rough transition. This is called a “Blended Chamfer”. Machinists and machines struggle with these precise finishes because there is so much room for error. If the chamfer is brought too far or not smoothly overlapped it risks a poor finish to the part.

Bump

The first motion of our operation for these gears is a ‘bump’. This seesaw motion can be performed very quickly and with our grinding wheels pressing all at once instead of dragging the edge it makes for an even quicker operation. 

Interpolate

Following the ‘bump’ finish along the outer edge, our machine ‘interpolates’ the top of the gear. This is where the chamfer is blended into the first ‘bump’ finish creating a consistent edge. The customer’s gear shown here also had 3 different angles on the top of the teeth. Our machine matched each angle and performed the 3 different passes for each angle on the gear tooth.
