Drill chucks mounted by Jacobs tapers onto arbors with Morse tapers for the spindle. Spindle nose on a lathe headstock. The small female taper is a Morse taper to take a lathe center or a tool such as a twist drill. The large male taper takes a lathe chuck, which is retained by the large nut.
The peak of popularity for building this type of spindle nose was the 1940s and 1950s. The chuck may be held against the taper with cam-lock posts that wedge into a stuck-fast position. Industry-standard spindle nose designs allow wide interchangeability. This cam lock spindle nose system replaced the earlier systems on most machine tools in ...
An automatic lathe may have a single spindle or multiple spindles. Each spindle contains a bar or blank of material that is being machined simultaneously. A common configuration is six spindles. The cage that holds these six bars of material indexes after each machining operation is complete. The indexing is reminiscent of a Gatling gun.
A line drawing showing some basic concepts of speeds and feeds in the context of lathe work. The angular velocity of the workpiece (rev/min) is called the " spindle speed " by machinists. Its tangential linear equivalent at the workpiece surface (m/min or sfm ) is called the " cutting speed ", " surface speed ", or simply the " speed " by ...
In machining, a metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals ; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range ...
A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
The drawbar pull is an important component that allows the milling machine to keep the tool in place while it’s being used. The force from the drawbar pull supplied to the tool has to be just right because not enough force would cause the tool to wobble leading to inaccuracy, and too much force would apply excessive stress, leading to shorter tool life.
A brass vase spun by hand. Mounted to the lathe spindle is the mandrel for the body of the vase; a shell sits on the "T" rest. The foreground shows the mandrel for the base. Behind the finished vase are the spinning tools used to shape the metal.
