# High Rigidity Is Necessary to Counteract Cutting Forces

## High Rigidity Is Necessary to Counteract Cutting Forces

During machining, spindle bearings are subjected to significant cutting forces: radial, axial, and tangential. Insufficient bearing rigidity leads to deformations, vibrations, and loss of machining accuracy.

## Sources of Loads

- Radial forces from cutting
- Axial forces from tool feed
- Moments from eccentric loads

## Solutions

High-rigidity bearings are used: cylindrical roller bearings, tapered roller bearings, and precision ball bearings. Preload is applied to increase rigidity. Pair mounting of bearings ensures uniform load distribution.
