What is the taper per foot used on milling machine spindles?

3 1/2" per foot
2 1/2" per foot
1 1/2" per foot
4 1/2" per foot

The correct answer is: 3 1/2" per foot

Milling machine spindles typically use a taper of 3.5 inches per foot. This taper is designed to accommodate various tooling and ensures a secure fit while providing stability during machining operations. The specific angle allows for easy alignment and minimizes the chance of tooling loosening during use. Additionally, this taper facilitates the interchangeability of tools, which is essential for efficient operation in a milling environment. The other options represent tapers that are either too steep or too shallow for standard milling applications. Understanding this taper is crucial for millwrights, as it directly affects tool setup, precision in machining operations, and overall equipment performance.
