  2. Broaching (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Broaching_(metalworking)

    The broaching machine elevator, which is the part of the machine that moves the broach above the workholder, then lowers the broach through the workpiece. Once through, the broaching machine's puller, essentially a hook, grabs the pilot of the broach. The elevator then releases the top of the follower and the puller pulls the broach through the ...

  3. Machining - Wikipedia

    en.wikipedia.org/wiki/Machining

    Broaching can refer to two operations, linear broaching, where a multi toothed tool is pressed through a hole to cut a desired shape (e.g. a spline, square, or hex shape) or along a surface by taking increasingly larger cuts by the increasing sized teeth of the broach; or rotary broaching, where a drafted tool is rotated in a special toolholder ...

    The Moore family firm, the Moore Special Tool Company, independently invented the jig borer (contemporaneously with its Swiss invention), and Moore's monograph is a seminal classic of the principles of machine tool design and construction that yield the highest possible accuracy and precision in machine tools (second only to that of ...

  6. Gear cutting - Wikipedia

    en.wikipedia.org/wiki/Gear_cutting

    Some machines will cut to a depth on the Y axis and index the rotary table automatically. The largest gears are produced on these machines. Other operations such as broaching work particularly well for cutting teeth on the inside. The downside to this is that it is expensive and different broach sticks are required to make different sized gears.

  7. Electrochemical machining - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_machining

    The vertical machine consists of a base, column, table, and spindle head. The spindle head has a servo-mechanism that automatically advances the tool and controls the gap between the cathode (tool) and the workpiece. [1] CNC machines of up to six axes are available. [2] Copper is often used as the electrode material.

  8. Key (engineering) - Wikipedia

    en.wikipedia.org/wiki/Key_(engineering)

    There are three main steps in broaching a keyway: First, the workpiece is set on the arbor press and the bushing is placed in the opening of the workpiece. Next, the broach is inserted and pushed through, cutting the keyway. Finally, shims are placed between the bushing and the broach to achieve the correct depth necessary for the key. [6]

    Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...
