We illustrate a horizontal boring, drilling, and surfacing machine, constructed, says Engineering, by Mr. W. Asquith, of Highroad Well Works, Halifax, for an engineering firm in the United States. The main standard carrying the steel-boring spindle, which is 6 in. in diameter, is adjustable vertically and transversely both by band and power. The spindle is capable of variable feed in either direction, and can be made stationary for surfacing. It can also be withdrawn instantly from the work when required. The two standards, which carry the bearings for the boring bars are adjustable in any direction by hand. There are also two portable standards carrying boring heads. These have self-acting feed motions, and are designed for drilling or boring objects simultaneously with the main boring spindle. The whole apparatus is mounted on a strong cast iron bed-plate, 24 ft. long by 8 ft. wide, accurately planed on the face, sides, and slots, and weighs 25 tons. |
