This machine is designed to take the place of several machines. It is especially suitable for the small manufacturer, the portable machine shop and the automobile service station. Two operations can be performed at the same time by one operator, or two persons can work at the same time on different jobs. Threads both English and metric can be cut on this machine when it is being used as a lathe. The bed is built with a removable gap block; is well braced with “U” cross supports and is thoroughly seasoned before and after machining previous to the final finishing to insure accuracy. Compact construction of the headstock is secured by passing the milling machine arbor support through and over the top of the headstock. The spindle of crucible steel is finished ground and runs in bearings of hard phosphor bronze. Adjustable dials graduated in thousandths are fitted. The milling table is provided with oil grooves and pockets and has three “T” slots. The feed screws and drill spindle are fitted with ball thrust bearings. All feeds are positive. Changes can be made on the milling machine without the use of loose gears. On the lathe the changes of feed are made by loose gears to the index plate furnished. The total length over all is 7 ft. 10 in.; total height to the top of the drill spindle is 6 ft. 5 in.; total width, 3 ft. 1% in.; net weight, 2000 lbs. |
