    en.wikipedia.org/wiki/Machine_taper

    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 machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool.

  3. Chuck (engineering) - Wikipedia

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

    A hollow drawbar passes back through the headstock to its back side, where a closer mechanism is mounted. The latter allows easy, rapid opening and closing of the collet. The drawbar's inner diameter determines the through-the-spindle bar diameter capacity of the lathe. Some collet-closer systems even allow opening and closing without stopping ...

  4. Collet - Wikipedia

    en.wikipedia.org/wiki/Collet

    Watchmakers' lathes all take collets which are sized by their external thread. The most popular size is 8 mm which came in several variations but all 8 mm collets are interchangeable. Lorch, a German Lathe maker, started with 6 mm collets and the first Boleys used a 6.5 mm collet. 6 mm collets will fit into a 6.5 mm lathe but it is a poor practice.

  5. Center gauge - Wikipedia

    en.wikipedia.org/wiki/Center_gauge

    Center gauges and fishtail gauges [1] are gauges used in lathe work for checking the angles when grinding the profiles of single-point screw-cutting tool bits and centers. In the image, the gauge on the left is called a fishtail gauge or center gauge , and the one on the right is another style of center gauge .

    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.

    Dead center (the conical piece) mounted in the spindle of a lathe and being used to support a workpiece being driven by a carrier setup. A lathe center, often shortened to center, is a tool that has been ground to a point to accurately position a workpiece on an axis. They usually have an included angle of 60°, but in heavy machining ...
