Although Mikron were to eventually build a number of larger precision toolroom-class milling machines of the Deckel FP type (listed as the WF23S, WF3S, WF3-DCM and WF2/3-DCM), for many years they were better known for a range of small bench horizontal and vertical types. Like similar models from Stark, The American Watch Tool Company, B.C. Ames, Wade, Pratt & Whitney and others in the U.S.A. the Mikron millers all used modified lathe headstocks mounted on a substantial main column with a conventional knee and table assembly. The top of the column was formed with the same section as found on the bed of a Mikron precision bench lathe - a fitting that allowed an instant change from horizontal to vertical modes, as well as permitting the use of a customer's existing lathe headstocks. All versions had the same size of table, 360 mm x 115 mm, able to be controlled by either screw or lever feeds. When fitted with screw feeds (Base No. 93) the table travel was 180 mm longitudinally, 70 mm across and 135 mm vertically while lever control (Base No. 94) gave, respectively, 250 mm, 70 mm and 120 mm.  Each table axis was fitted with an adjustable length stop.
Based on the design of the ordinary lathe headstocks the ones for the milling machine were, however, specially adapted to their task. The basic unit was the No. 95, with no arbor support and intended only for simple stub milling. Instead of the 4-step cone pulley of the lathe headstock this used a wider 3-step type (diameters 85, 107 and 125 mm to take a 40 mm wide belt) with the hardened ground and lapped spindle running in parallel bronze bearings tapered on their outside for adjustment. Run from a 2-speed motor with double-step pulley drive to the countershaft, 12 speeds were available from 120 to 1350 r.p.m. However, when fitted with a 3 : 1 epicyclic reduction gearbox within the pulley (as Headstock No. 95a), this number rose to 24, spanning a very useful 40 to 1350 r.p.m.
If the requirement was for a conventional horizontal milling with a supported arbor, headstock No. 99 could be ordered. Again, this used the main components from the No. 95, but with the addition of a built-in, round overarm. For vertical milling headstock No. 97 was provided and, again based on the No. 95, employed the same spindle, bearing and pulley assembly and with the drive from the horizontal spindle to the vertical by bevel gears. The unit could be swivelled through 90° in either direction.
Unusually for a small milling machine, a table power-feed unit was available (No. 98) and, driven from a small 3-step pulley on the headstock, gave feed rates of 0.05, 0.10 and 0.20 mm per revolution of the spindle..
