Schaublin 22 milling machine

SV22-1The 22 was the last tool-room milling machine to be developed by Schaublin SA. Sold between 1967 and 1995, in some respects, it can be regarded as Schaublin’s answer to the Bridgeport-type turret mill. However, it proved to be a slow seller with just over 600 machines produced in 28 years.

As with the 53, Schaublin abandoned the “continental pattern” and opted for a knee type design for the 22 but retained the movement of the milling head to give the X axis. With a table measuring 650x250mm, travels¬† were somewhat unusually proportioned at 330mm longitudinal (x), 400mm headstock (y), and 475mm vertical (z). Feeds to the longitudinal (x) and vertical (z) axes were infinitely variable and selected via a joy-stick mounted on the face of the knee. A clever electro-mechanical system of stops and miroswitches allowed “programmable” cycles to be set on the machine.

Unusually, the 22 employed a milling head that tilted front to back rather than side to side. The 30 ISO milling head featured a lever operated sliding quill and was powered by a two speed 1.5kW motor driving a six speed gearbox providing twelve speeds between 63 and 2800 rpm.
