Milling machines and Computer Numerical Control systems (CNC) are used in milling of different types of gears and surfaces etcetera from metal surfaces or other types of surfaces. These machines are conspicuously universal in the manufacture of gears among other things. Universally applicable milling machines could be applied in different types of drilling, reaming and milling of steel metals and other types of metals. They can be used in medium or low quality production series.
Functional qualities of milling machines
Milling machines will regularly be automated and could function from a horizontal or vertical position in curving out of materials based upon an already existing design. Most milling machines are directed by CAD and are controlled by CNC systems. Conventional and manual milling devices are also in common use. Milling machines have capacity to move dynamically both for the work piece and the tool. Most milling machines will also perform machining on multiple axes. Due to the differences in orientation, application and operation, milling machines will often have a variety of functionalities and differences in principles of operation.
Tooling: The milling machine could be fitted with various tool heads with an objective of meeting varying machining needs. The different tool heads may include ball end, fluted, rounding and cutters mills. Some of these machines have tool ends that rotate and could be changed based on the prevailing need. A computer program is designed to communicate when a change of tools is needed.
Tools are picked depending on desired shape and material in use. Since materials such as steel, plastic and wood have varying physical characteristics, a variation in tool bits used is necessary. This ensures materials are properly machined. In case the tool bit used does not meet the strength quality needed for steel machining, both the machine and tool could get damaged. Tool bits that are stronger than material could as well damage work pieces.
Milling machine types
Categories of milling machines are identified based on the work pieces and motion degree.
Plain Horizontal and vertical Machines: These are milling machines that have typical working surfaces with horizontal or vertical orientation. Tooling equipment is usually fixed on swivel or turret. The tools are placed in parallel positions to work space. Swivel and turret makes it possible for free tool movement around work piece area in order to allow for tolerance of force.
Knee Type machines: They operate in a vertical position with support from a knee. The knee is adjustable. This knee offers support to a saddle and allows for adjustments in order to customize a work space depending on the needs.
Universal Ram Machines: Ram type machines are used in order to make it possible for tooling equipment to take position on larger spaces in relation to a work piece. This machine has spindle placed on movable housing. The spindle could move on some horizontal plane. This category of milling machine entails some swivel housing capable of increasing the scale of movements for cutting.
Swivel Cutter Head Ram: This milling machine has a swivel which rotates from an absolute vertical position and down to a horizontal position. Working table is also designed to move accordingly making it possible for user to enjoy liberal orientation and motion. Most swivel cutters have entail hand driven or automatic settings which increases the options of operation.
Universal Horizontal Machine: This machine is different from pain horizontal machine. It houses the table swivel which essentially makes it possible to have the table move for up to 450 from the horizontal position. The movement makes it possible to enjoy easy helical and angular milling functions.
