Milling – other – cherrying

The Bridgeport milling machine has as an optional extra known as a cherrying head.

This head looks like an ordinary vertical milling head head. But when it is running the spindle, as it rotates, oscillates from side to side and moves up and down so the tip of the cutter moves in an arc in the x/z plane.

It appears that the cutter used on this was like a four fluted ball ended mill but was round – hence, possibly, looking like a cherry.

There are videos of this on YouTube but not actually doing any cutting.

These were designed to be used for die sinking, ie, making moulds.
