BORING MACHINE
Our illustration on this page shows a very handy form of horizontal drilling and boring machine, made by Mr. W. Asquith, of the Highroad Well Works, Halifax, and which, in places where it cannot be fully employed in boring and drilling, can be used to great advantage as a turning lathe for chuck work, or as a heavy milling machine for plain milling or for grooving shafts. The spindle is steel, 3 in. in diameter, having a self-acting feed of 30 in. It is carried in a strong cast-iron sleeve, working in conical bearings, and retains its original alignment when required to be adjusted. The spindle is arranged with hand and self acting feed in either direction, varying from 90 to 8 cuts per inch, and there is also a stand for surfacing. The direction of the feed can be reversed or stopped instantly, and the spindle can be very quickly withdrawn or put to any position required. The vertical slide, as well as the compound table, is adjustable longitudinally, transversely, and vertically, and suitable provision is made for firmly securing it in any position required. The machine is also fitted with a portable revolving worktable not shown in the illustration. The steady bush through which the bar slides revolves in conical bearings, keeping perfect alignment and preventing wear in the bar. The feed rack and pinion are of steel, and machine cut, as is all the other gearing in the machine. The weight of the machine is 75 cwt. |
