The last step in rebuilding the Schaublin 13 has focused in th
electrical cabinet and wiring. The machine has been adapted to
ordinary 230V monophasic mains by using VFD’s and all the control
circuits have been assumed by the same VFD’s.
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
🤨.
Nothing annoys more to me that a machine loosing oil and spilling it
on the floor. Despite this, many machines are designed with not too
much attention to this detail and lost oil mechanisms are usual. The
Schaublin 13 has also some mechanisms that loose oil by design and
some of them spill the oil on the floor.. ugly design I would say.
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 the way of renovate the Schaublin 13, it is time to manage the lamp
support and its connection. Lamp is attached to the side of the
machine and, in the interior, a small junction box would be
desirable. I tailored a made-to-size box of steel sheet.
