# Boring Machines

## Boring Machines

Boring machines are designed for machining precise holes and internal surfaces. The spindle of a boring machine operates under high axial loads and requires minimal runout to ensure machining accuracy.

## Requirements

- Minimal spindle runout
- High rigidity under axial loads
- Precise positioning

## Solutions

Precision cylindrical roller bearings and thrust ball bearings are used. For high-precision operations, P2 class bearings with preload are recommended. Oil lubrication is advised to ensure stability.
