South Bend Lathe is a brand of machine tools. Today's South Bend Lathe corporation is the successor to the original South Bend Lathe Works , an American machine tool builder that for many decades was one of the most important builders [ citation needed ] of metalworking lathes in the U.S. and in the world.
The Johnson Press and Deka Drill service parts businesses were acquired from South Bend Lathe in 2001 and the South Bend Lathe and Dynablast parts businesses in March, 2002. LeBlond's product support team had collectively 160 years of service with LeBlond Machine Tool Company, LeBlond Makino and Makino.
The Singer Manufacturing–South Bend Lathe Co. Historic District is a national historic district located at South Bend, St. Joseph County, Indiana.It encompasses four contributing buildings, one additional contributing structure, and one further contributing site as contributing properties.
The closer on a manual lathe is either lever-style or handwheel-style. The closer on a CNC lathe is powered (electric, hydraulic, or pneumatic), and it may be controlled by various means: a foot pedal that the operator steps on when desired; a line in the program (for opening and closing under program control); or a button on the control panel.
A set of change gears is provided to select the ratio between the table feed and rotation. This setup allows the machining of spiral or helical features such as spiral gears, worms , or screw type parts because the part is simultaneously rotated at the same time it is moved in the horizontal direction.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
A crossed helical gear is a gear that operate on non-intersecting, non-parallel axes. The term crossed helical gears has superseded the term spiral gears. There is theoretically point contact between the teeth at any instant. They have teeth of the same or different helix angles, of the same or opposite hand.
Square threads are named after their square geometry. They are the most efficient, having the least friction, so they are often used for screws that carry high power; however, they are also the most difficult to machine, and are thus the most expensive.
