Lorch Milling Machine
As a maker of machine tools dedicated to the production and repair of clock, watch and mechanical instrumentation, Lorch concentrated mainly on lathes of various kinds and specialist tooling and accessories. However, needing to offer a small milling machine, they followed the established lead of some American makers of precision bench lathes - notably Ames, Cataract, Pratt & Whitney, Stark and Waltham - in offering one based on a modified lathe bed and headstock. However, in comparison to the American machines, the Lorch was a more ambitious undertaking, with a proper backgeared headstock and the assembly carried on a cast-iron stand with a built-in drive system (the latter neatly modified by the present owner). In addition the table has power feed through a telescopic shaft and universal joints, the method of engagement being the usual one for this type of drive with a gear (wheel) fastened to the table feed-screw and driven by a worm carried on an arm that could be moved into and out of engagement. Fitted with zeroing micrometer dials from one of the larger Lorch lathes, the table and its range of feeds would have been entirely adequate to carry the sort of job typically encountered in a workshop dealing with small precision parts.
In order to improve its appeal to owners of Lorch lathes, the miller would have been offered with a replica of a lathe bed to fasten to the T-slotted table. This would have allowed the mounting of expensive accessories already in stock such as dividing heads and rotary tables.
The machine shown below is very rare and, should you have a similar example, the writer would be very interested to hear from you.
