Schaublin 11 and 12 Milling Machines

Later Schaublin 11B from a 1946 catalogue

The Schaublin 11 and 12 milling machines were the smallest capacity machines in the Schaublin range. The SV11 is an extremely rare machine and I only know of one machine in the UK. Based around the SV65 and 70 lathes the SV11 was aimed at the same market as the Aciera F12 and later the F1. However, the Aciera machines were far more versatile and consequently quickly gained an excellent reputation and sold in large numbers.

The SV12 employed a 4MT for both the horizontal and vertical spindles, but is most commonly found fitted with a reduction bush to take W20 collets. While a variety of tables were available most machines have the table illustrated below with a profile corresponding to the beds of Schaublin 90 and 102 lathes. This is a very limiting factor which is often overcome through the adaptation of a box or angle plate to form a more conventional table. Most SV12s were made in the 1950s, however a few produced in the 1960s are in existence. These later machines had taller machine bodies giving a longer vertical stroke and hence more capacity under the cutter.

The SV12 sold in far greater numbers than its smaller stable mate, but none-the-less is infrequently encountered.

SCHAUBLIN 12 MULTI-PURPOSE HIGH PRECISION Ml LLING MACHINE

Introduction

The SCHAUBLIN 12 milling machine has undoubtedly the finest reputation of all existing multi-purpose milling machines. It is used in all kinds of industries throughout the world and has proved itself to be the ideal machine for single jobs and toolmakers' work. Its superiority lies in the simplicity of its construction and the outstanding economy achieved in production work.

The numerous appropriately designed attachments offer a variety of practical set-ups and make the SCHAUBLIN 12 a truly "universal" machine. In addition to this, many of the attachments belonging to the world-renowned SCHAUBLIN 102 lathe can be used on it. Consequently, it is an indispensable item of equipment for all firms aiming at the standardization of their manufacturing plant.

The many different applications of this machine are made readily apparent by the short description contained in the present catalogue, which, in conjunction with illustrations of some of the various set-ups, outlines the features of the principal attachments. It is only by making full use of these applications that the machine will render the service which may be rightly expected of it.

The SCHAUBLI N 12 milling machine is normally supplied with a horizontal cutter head with a No. 4 Morse taper. The cutter head slides in a prismatic guideway and can be equipped, as required, with a plain cover and an overarm with arbor support or, to special order, with a vertical cutter head or a slotting attachment. The longitudinal slide is mounted square with the machine frame and possesses an angle bracket suitable for accommodating

a saddle of the same profile as the bed of the SCHAUBLIN 102 lathe,
a rectangular table,
a semi-circular table,
a rotary circular table.

When the angle bracket is removed, the longitudinal slide will accommodate:

an inclinable table,
an inclinable quill-holder,
any special attachment for a given job.

A special device is provided for the automatic longitudinal feed of the table.

The base of the machine houses the single or 2-speed electric motor, the individual drive, and the coolant system.

The SCHAUBLI N 12 milling machine forms a compact unit. Installation is limited to cementing-in the stand and connecting up the motor to the electrical supply.
