Many sectors in the manufacturing industry heavily rely on fabricated parts and components to make the final product. CNC machining is widely used for this and various techniques are used to achieve different shapes, sizes, and dimensions. These include milling, cutting, and forming, and so on. There are CNC machines exclusively for milling, while there are others where multiple tasks can be performed in a single machine. Among these machines and equipment used in the industry, the milling machine has gained traction. A milling machine is used during the metal cutting process for producing parts of various shapes and sizes. Are you intrigued to know the details of milling machines and their types? If so, then read the following post which answers these questions and more. So, stay tuned.
Short Introduction to a Milling Machine
Before proceeding with the types and operations performed on a milling machine, it is vital to understand what it is. A milling machine is the most popular and preferred equipment for shaping solid materials, including wood or metal. It has a cutting tool that helps machine workpieces of almost any shape or size. The machine features different parts in conjunction with one another. The list includes base, column, knee, saddle, spindle, table, overhanging arm, elevating screws, arbor, and so on.
Different Types of Milling Machine Discussed
Primarily, milling machines are categorized into two types – vertical and horizontal milling machines. Further, they are classified as ram-type, knee-type, planer-type, and manufacturing or bed-type milling machines. All milling machines classified above feature an electric motor, variable spindle speeds, power-operated table, and coolant systems.
- Vertical Milling:
Vertical milling machines mount the cutting tool on a vertically oriented spindle that removes materials from the stationary workpiece. Vertical milling machines differ from horizontal milling machines in several ways. The biggest difference is the length and size of cutting tools. Unlike horizontal, vertical milling machines have long and thin cutting tools, making them a smart investment for several manufacturing companies.
- Horizontal Milling:
This is the most common type of milling machine. As the name suggests, the horizontal milling machine features a horizontally oriented spindle that holds as well as rotates the cutting tool against the stationary workpiece. With shorter and thicker cutting tools, the horizontal milling machine can perform heavier and deeper cuts. Therefore, several manufacturing companies often use them to cut slots or grooves into workpieces.
- Ram-type Milling:
This type of milling machine features ram on the top of the column, thus called a ram-type milling machine. The ram can slide forward and backward to shift the cutter position quickly.
- Knee-type Milling:
This type of milling machine features a knee-like projection in the middle. A knee-type milling machine is characterized by a vertically adjustable table that rests on a saddle supported by a knee. Owing to their flexibility and versatility, knee mills have become the first choice for prototyping, tooling and fixture work, and many more tasks.
Milling machines are a great boon for manufacturing units that need quickly fabricated parts and prototypes. Therefore, it is crucial to avail milling services from an industry expert to get precise machine parts.
