Ball-Bearing Machine-Tool Spindles
Thomas BarishAbstract
This paper is a review of the three types of ball-bearing machine-tool spindles now in use, showing how rigidity is obtained in each type and what results are secured. There is also a historical review of the first type, which was originally put into service over ten years ago and has since received minor improvements. The three main groups are:
(a) Two-bearing, manually adjusted spindles
(b) Automatically spring-adjusted spindles
(c) Three-bearing spindles, adjustable and non-adjustable.
Comparisons are made between the various types for their rigidity, and some deflection curves and actual measurements of rigidity are quoted.
