A tool bit (or several tool bits) and a compact follower rest (usually V-shaped or with two rollers [2]) are mounted opposite each other in a body which surrounds the workpiece (forms a "box" around ...
Working from engineering drawings developed by the toolmaker, engineers or technologists, tool makers lay out the design on the raw material (usually metal), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, and jig grinders), power tools (such as die grinders and rotary tools), and hand tools (such as files and honing ...
Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized. An important early example of ...
In the craft of woodturning, a banjo is a common term for a fixture on the wood lathe, [1] mounted on the lathe's bed, for holding the toolrest. It allows for adjustment of the toolrest in various positions, by the lathe operator, making it possible to hold the turning tool in the most convenient position for removing material from the spinning ...
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.
