The 1760–1840 development arc was a tremendous technological advance, but later advancements would make screws even cheaper and more prevalent yet again. These began in the 1840s with the adaptation of the engine lathe with a turret-head toolholder to create the turret lathe. This development greatly reduced the time, effort, and skill needed ...
For example, gang drills and many screw machines are multispindle machines. Although a bench lathe has more than one spindle (counting the tailstock), it is not called a multispindle machine; it has one main spindle. Examples of spindles include On a lathe (whether wood lathe or metal lathe), the spindle is the heart of the headstock.
For example, a centering lathe is a dual head machine where the work remains fixed and the heads move towards the workpiece and machine a center drill hole into each end. The resulting workpiece may then be used "between centers" in another operation. The usage of the term metal lathe may also be considered somewhat outdated these days ...
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.
A backplate with threads may screw onto a threaded spindle nose (for lathe work) or onto an adapter plate with the same nose, to be mounted on the table of milling machines or surface grinding machines. This "threaded spindle nose" type of mounting was the typical method in the 19th century through 1930s.
The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working backward from the desired surface speed (sfm or m/min) and incorporating the diameter (of workpiece or cutter). The spindle may hold the: Material (as in a Lathe chuck) Drill bit in ...
