First up is an introduction to milling machines, where you'll learn the basics of when and how to use a milling machine in your Fusion 360 workflow. Milling machines are comprised of a spindle that holds a cutting tool and Workholding that holds the components. The spindle rotates and cuts the paths, while the Workholding holds the part.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. The type of milling machine most commonly found in student shops …

10.1 Introduction. The main function of a lathe is to remove metal from a piece of work to give it the required shape and size.This is accomplished by holding the work securely and rigidly on the machine and then turning it against a cutting tool which will remove metal from the work in the form of chips. 10.2 Types of Lathes.
