The Kaiser Piccolo is an exquisitely made mid sized boring head with boring and automatic facing functions. I got a ISO30 one in a very nice condition together with a bunch of tooling. When tested it performed very fine but I couldn’t switch easily between facing and boring (marked as P and A in the head, maybe for the french «planage» and «alésage»). It needs to be serviced to cope with this jam.

The milling machine is built in France in the late 60’s (acording to the plate the april of 1968).

The Leinen LZ4SB leadscrew is supported by two bearings. One of them, the corresponding to the adjusting end, has been eroded maybe for a deficient lubrication. This need to be faced again to recover the bearing surface. We plan to do that using a boring head on the milling machine. To support the part in an orthogonal position first an adjusting stud is turned in a lathe. This will guide the bearing when clamped to the table.
