Power down-feed to the quill was available as an extra-cost option, the feed rates being 0.0015", 0.003" and 0.006" per revolution of the spindle. Two automatic stops were fitted, one being permanent to guard against overrunning and consequent damage, the other able to disengage the drive at any selected point.
For horizontal work, the end of the ram was fitted with a drop bracket and a cutter-holding arbor in a ground-finish, chrome-moly steel that ran in #5 preloaded precision angular contact bearings at the front and a single-row, double-shielded ball race at the other end. The arbor was driven by a housing sitting on a flat surface to the right-hand side of the turret-supporting boss with power provided by a separate, 1 h.p. single or 2-speed motor pivoting from the right of the arbor housing. Drive was through V-belts and an epicyclic backgear assembly - this latter being more heavily built than the one on the vertical head. With the single-speed motor and backgear eight speeds of 110, 255, 280, 980, 1470, 2250 and 3600 r.p.m. were provided and with the 2-speed motor sixteen of 55, 110, 128, 140, 255, 280, 320, 490, 640, 735, 980, 1125, 1470, 1800, 2250 and 3600 r.p.m. Like the vertical spindle - and so allowing the same tooling to be used, the horizontal spindle was fitted with an American No.30 National Standard taper with a positive key drive.
Sliding up and down the main column on a 12-inch wide dovetail cast integral with the main column, the saddle had a 14-inch long bearing support and total vertical travel of 16 inches. Vertical adjustment was by a handwheel, fitted at an angle to the left with a micrometer dial engraved to read at intervals of 0.001". Bevel gears turned the drive through 90° turn a vertical screw resting on an anti-friction bearing.
Fitted as standard was a 9" x 36" table with three T slots, a surrounding coolant trough and both the top and side surfaces ground-finished. Feed was by a hand-tuned screw with balanced handwheels provided at both ends of the table. Longitudinal power feed was an option - though not vertical or in traverse - the drive coming from a 1/3 h.p. motor driving through sets of paired, hardened-steel pick-off gears. By juggling the gear pairs - they were stored in a housing within the main column - feed rates ranging from 1/2" to 13" per minute were possible. Additional sets of pick-off gears could be ordered such that 81 different feed rates could be selected, these ranging from 0.515" to 13.125" per minute. Adjustable, automatic knock-off stops were provided for both directions of travel as well as a slipping clutch mechanism to protect against overload damage or being fed past the end stop. Fitting the table-feed accessory reduced the table's longitudinal travel by 3 inches.
Lubrication was by a third-party-provided, one-shot system built into the saddle that sent oil to the table and knee ways and the feed-screw nut. A sight-glass level indicator was provided with eight points lubricated by one push of the button. Other oiling points were fitted with the usual Zerk fittings.
In addition to those accessories already listed, 10R and 10RH could be provided with a powered, 4-inch stock self-powered slotting attachment, hydraulic copying, an electric coolant system, precision location equipment with micrometer dials reading down to 0.0001", collet chucks, boring heads, plain and universal dividing heads, 3-jaw chucks, rotary tables, standard and swivel-base machine vices, No.30 NST to Morse taper adapters and various drill chucks.
All castings used in Axelson machine tools - millers and lathes - were poured in the maker's own foundry in what was termed "Axoly Alexson #35 CNM semi-steel" - this being a formulation containing chrome, nickel and molybdenum. It was claimed to have a modulus of elasticity of approximately twenty million - compared with eight million for ordinary cast iron - and was designed to have high strength, rigidity and great resistance to wear..
11/2V Ram-turret Milling Machine
Identical in layout to the 10R and 10RH millers with the same main column, knee and table and centralised lubrication system, the 11/2V Ram-turret Milling Machine was a simplified model. It had no horizontal ability and a single ram slide with, as standard 12.5 inches of travel or, as an option, the double-slide unit from 10RH with 22 inches. The vertical head - Type 30 all-angle - was also the same, though the epicyclic backgear was an extra-cost option and was the power down feed. In standard, direct drive form the head could be had with a single or two-speed motor that gave 6 and 12 speeds respectively; with backgear fitted a choice of 8 or 16 speeds became available. The full list of speeds is shown below:
