There are several types of machines used in knee milling processes. The basic function of any type of milling machine is to move the workpiece from one position to another. Depending on the type of machine, the different processes can be separated into various categories: Vertical Milling Machines. These machines have an arm that runs vertically through a workpiece, providing it with the required turning direction. Vertical milling machines are also known by the names horizontal milling machines and cross-cut machines.
Other operations like drilling, perforating, etc. are performed in a horizontal manner. There are a variety of operations performed in a vertical manner as well. Some of the most common types of operation like grinding, punching, etc. are also performed in a vertical manner.
A Knee Type Milling Machine consists of two major parts: The cutting unit and the stationary cutting device. The cutting device in the machine is commonly made up of a diamond core blade or a ceramic tile and the magazine is rigid sheet metal or a hollow steel rod. The magazine is fitted with a rotating screw that is attached to the cutter. The tile is placed inside the magazine and the operations like drilling, perforating, etc.

Types of Knee Type Milling Machines
There are two types of Knee Type Milling machines, namely, vertical and horizontal. The vertical milling machines are used for plate capacity type production work and the horizontal milling machines are used for less plate capacity work. The products produced by these machines are generally made from material that is of fine tolerance. These products are usually produced on an individual basis and there is no interference during production work with other machines.
Vertical machines are fitted with large spindles which have the capability to lift the material to very high production levels. The horizontal machines are fitted with small spindles. The vertical milling machines are designed for the high production of small diameter circular parts. The horizontal milling machines use ball bearings to operate the cutting operation and the products produced by these bearings are of fine tolerance. Knee-type milling machines are very reliable and operate at a fairly low voltage. They are also quite energy-efficient and give the right results.
