The single spindle automatic lathes model LA and TA, are used for the manufacture of a great variety of simple and complex turned parts which are relatively short as compared with their diameters. For example, bolts, screws, nuts, sleeves etc., all kinds of materials such as steel, brass, aluminum etc. can be machined on automatic lathes. The machine, model LA, is available as LA25, execution for machining round and profiled bars up to a max. diameter of 25mm as well as TA25 automatic having the same range of application. The models LA32H and TA32H have a spindle capacity of 32mm with hydraulic stock chucking, bar material up to dia.32mm can be machined. TA16 is for small material stock and high speed turned parts. For secondary operation of pre-machined parts, the automatics can be equipped with a magazine feed attachment or a hand chucking device if only small volume are involved. The working scope of the basic machine can be enlarged considerably by the application of the various attachments.
