Sharp Teeth
Stamping to a sharp point presents a particular challenge in our industry. The sharper the point, the faster the die wears, and the greater the likelihood of part distortion and burring.
We recently undertook a series of parts that not only had to taper to small, fine points, but also needed to follow a specific radius to align and lock with a toothed nut.
In the past, when we had to make sharp teeth for a can opener, we would stamp the general shape and then come back to shave both sides to form a point.
Although this requires more operations and increases die maintenance (to maintain a sharp cutting edge), the cost is still considerably lower than machining or grinding.
