Milling Machine
Milling machines invented, by Eli Whitney, were first used in an industrial setting to produce parts for muskets. Milling machines helped remove metal burs created by the cutting of a machine during manufacturing. Over the course of history milling machines have been improved upon. As technology updates, so does the method of machine control. Milling machines have various attachments used in boring, slotting, cutting key ways, and gears for manufacturing and processing. There are a few different types of milling machines. These machines are classified by the shape of the axis spindle they contain, vertical, or horizontal. The different types include ram-type, knee-type, manufacturing or bed type, and planer-type. Milling machines can have one type of milling cutter, or multiple. Gang milling is the use of two or more mill cutters. They are attached to a horizontal mill, and can perform the same or different types of milling. Some CNC machines use 4-5 axis’s for gang-milling.
Manufacturing and production companies use milling machines to create different products. The machines can be used on a variety of materials that can be used in different industries. For instance, sprockets can be created using a milling machine. The spindle travels at above 10,000 rpms to create indentations, or cuts on the metal. Water is used to cool the material down so the spindle can continue to work without the material contaminating the product or the motor overheating.
