spindle nose

Between centres and a spindle nose of 7/8in.

This "threaded spindle nose" type of mounting was the typical method in the 19th century through 1930s.

This cam lock spindle nose system replaced the earlier systems on most machine tools in the 1960s.

They overlap somewhat (not entirely) with the analogous joining of lathe chucks to the spindle nose.

A drill chuck may have a hollow body that threads directly onto a lathe's threaded spindle nose.

Industry-standard spindle nose designs allow wide interchangeability.

The exact-adjust (Set-Tru) concept is one way to chase high concentricity on threaded spindle noses with some relative degree of ease.

Threaded spindle noses are still built on new machine tools, but only of the low-end variety (hobbyist, least-expense MRO, etc.).

On lathes, the male may belong to the tool or to the spindle; spindle noses may have male tapers, female tapers, or both.

The larger sizes are available threaded for any of the standard spindle nose thread forms, which need to be selected form the drop-down box after you have selected the required faceplate size.

These two committees worked in close cooperation with each other and with manufacturers and users of engine lathes, turret lathes and automatic lathes in developing standards for spindle noses and chucks.

The first edition of the Spindle Noses and Tool Shanks for Milling Machines standard, known as B5.18-1943, resulted from intensive effort dating back to 1926 by a special group of milling machine manufacturers.

Many lathes that run collet chucks have dedicated collet-closer setups whereby there is no backplate, and the spindle nose contains the female taper for either the collet's male outer taper, or a sleeve that will hold it.

It is simple and useful, but the degree of control of concentricity is not quite good enough to be foolproof for high-speed, high-precision work (high precision can be achieved, but the time and skill involved in the setups makes it a poor choice now that better options exist, such as the cam-lock spindle noses described below).
