Abstract

A milling machine with a copying facility has two tables 19, 16 driven by a motor 18 and connected for rotary movement by a chain 20, the first 19 carrying a drawing, and the second 16 a workpiece 17. A photoelectric head 39 follows a line on the drawing, and its radial movement controls the radial movement of a cutter 11, the connection between them being in the form of two coaxial leadscrews 30, 31, driven by a motor 25 and having different pitches so that the workpiece 17 is made to a predetermined reduction in scale compared to the drawing. <IMAGE>
