Hyde's Improved Cutting-Off Machine.
Among the recent labor-saving tools of the modern machine shop, there is none more useful than the cutting-off machine. The speed and accuracy of its work, the saving of time, labor and stock in subsequent operations, at once places this machine amongst the important factors in the economy of the machine shop. The cut, page 5, shows an im proved tool of this class recently brought out by Warren Haskell & Co.,36 Charlestown St., Boston, Mass., and which it is believed possesses points of superiority that will be appreciated by the practical mechanic.
There are two strong and powerful chucks —one on each end of the main spindle— designed and constructed expressly for this machine. The jaws do not project, consequently the cutting tool can be kept very close to the face of chuck, thereby avoiding the usual strain and leverage on chuck and spindle bearings.
The cones are of ample width and diameter; the bearings of main spindle are large and long.
A special feature of this machine, is the tool post or holder, which is of extraordinary strength and stiffness, and is provided with two lateral adjusting screws so that after once setting the tool perfectly true and square, it can be removed for grinding, and replaced in exactly its original position without loss of time, and without changing its distance from the length gauge. This machine has a cross-feed operated by the usual worm and gear, and also an automatic throw-off which stops the feed when the piece is cut off.
The length gauge is provided with a finger at its forward end, which can be thrown over, after gauging the length, to prevent cramping the tool as the piece drops off.
The countershaft has two changes of speed, making, with the changes on the cone, six different speeds for the main spindle. The pulleys on the counter shaft are driven by a simple and efficient clutch, so that by an instantaneous movement of the lever, the speed may be accelerated as the tool approaches the center. The "Slate" cutting-off tool and an adjustable stand for the support of long bars accompany the machine. Special effort has been made to entitle this machine to a place in the list of superior modern tools, in the belief that it will fill a place in the machine shop as yet only partially filled. |
