A.E.W. Horizon & Viceroy
Milling Machines

Operation and Parts Manuals are available for the AEW



. Built in East Anglia by the A.E.W. Engineering Company Ltd. of Horizon Works, Dereham Road, Costessey, Norwich, the "Horizon" was manufactured from 1961 until late in the 1970s and sold both by the maker and also branded as "Viceroy" for Denford Small Tools of Halifax, the original makers of what was, at first, called the Box-Ford lathe. The earliest sale recorded in the maker's serial number book was during January, 1964 for a machine marked 123-3P with the last, No. 998-V2PM, leaving the factory in April, 1978. Exports were recorded to Canada, Pakistan, Mexico, South Africa, U.S.A., Israel, Hong Kong, New Zealand, Germany, Holland, Singapore, Belgium, Thailand, Nigeria, Egypt, Ghana, Norway, Mexico, Sudan, Sweden and Australia.
Three types were offered listed as the Plain Horizontal, Universal and Vertical.
Universal (with a swing table):
1U - hand table feeds is all directions
2U - table power feed unit
3U - identical to the U2 but with the addition of a continuously-running spindle clutch that could be operated from either side of the machine.
Plain Horizontal:
1P, 2P and 3P all identical to the Universal versions but less the swing table
Vertical:
V1P with hand table feed
V2P with power table feeds
V1U hand feeds with universal swivelling table
V2U power table feeds with universal table
A letter M after the model indicated metric feed screws and dials; a letter E after the model indicated the fitting of a variable-speed table power-feed unit
e.g. 40171/1PM would be a plain horizontal machine made in 1971, Serial Number 401 and fitted with hand-feed to the table movements and metric feed-screws and dials.
Heavily built and with an excellent cosmetic finish, the A.E.W. was available with either a 28" x 8" (710 mm x 200 mm) or 38" x 8" (960 mm x 200 mm) table with three T-slots and offered in Horizontal, Vertical and Universal types, the latter with a swing table able to turn 45░ each side of straight. Travel was 19" (480 mm) longitudinally, 5.5" (140 mm) in traverse and 13.5" (340 mm) vertically on the Horizontal and Vertical types and 12" (300 mm) on the Universal. All versions benefited from the inclusion of an adjustable, longitudinal-feed backlash eliminator. From the start of production a power-feed attachment was available that gave 8 rates of automatically disengaged feed from 0.7 to 5" (17.5 to 126 mm) per minute. The unit was simple, consisting of a 1/6 h.p. motor-gearbox unit (upgraded to a 0.33 h.p. on later models) that used simple pick-off gears running in an oil bath that had to be changed by hand - spare gears were stored on a stud positioned low down on the right-hand face of the column. From the works records around 70% of the production was equipped with power feed, though only a tiny minority had the electronic variable speed control offered in the 1970s. Table feed-screws were normally fitted with traditional, balanced handles but if required, at extra cost, full-circle handwheels could be provided.
Covered by a full-depth, swing-open cover (with safety micro-switches), the drive on the Horizontal models was from a 2 h.p. 3-phase motor mounted on a hinged plate in the bottom of the column (the latter being bolted to a cast-iron base that doubled as a coolant tank). Available with the option of a clutch combined with the standard-fit 3-speed oil-bath gearbox, the drive was transmitted upwards by a V-belt running over a 3-step pulley and tensioned by a jockey wheel. At the spindle the drive could be either direct, or through a lathe-like reduction gear mounted just inboard to the spindle nose; the 18 speeds so generated ranging from 25 to 2039 r.p.m. Running on opposed, pre-loaded precision taper roller bearings, the horizontal spindle was fitted with a No. 30 INT taper - though others could be specially ordered to a customer's preference. The standard cutter arbor was in a forged, nickel-chrome molybdenum steel and took 1-inch bore cutters, though again, others could be had to special order. Supported by a box-section cast-iron overarm the end of the spindle ran in a ball race in a cast-iron housing.
Vertical machines omitted the based-mounted 3-speed gearbox and clutch and, with a 1 h.p. motor mounted higher up in the column, employed a 4-step V-pulley that could drive either direct, or be arranged to pass through the same backgear employed on the horizontal models. As vertical milling often involves the use of smaller cutters needing high speeds, the 8 provided were usefully faster than those on the other models at 80 to 3105 r.p.m. The head, with its 30 INT spindle running in ball races and an oil level
