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.
By some reason I thought since the begining of the overhauling that the gearbox was in a nice condition. Thus, I didn’t reviewed it. In fact, I didn’t even emptied the oil. During the overhauling of the SV13 the time arrived to check the gearbox. I switched the power on… and the gearbox made an intense rattling noise in some speeds 🤨.
Next step in the SV13 overhauling path has been to end the horizontal spindle head and mount it into its ways definitively. Some works remain to be done: finish the fitting of the slideways, clean and relube the feed screw assembly, do the cosmetic work and finally inspect and relube if needed the spindle bearings.
The Schaublin 13 longitudinal slide geometry was checked and its ways overhauled. This post explains how it was done.
In this post I show the result of carrying a sequence of tests to the rebuild Wörner drilling press to check its accuracy. I took an Aciera 10 drilling machine inspection chart as a reference. Both machines are of similar size and Aciera quality is second to none.
