CNC Milling Machines- The Revolution in the Industry of machinery!

Whenever you question a mechanist about how they are able to cut a slot into a workplace, you get to know that they make use of milling machines assuming that this statement would be enough to explain the entire process. However, it is suggested that a person answering that question should be a lot more precise as they should specify the type of machine that they brought in use. There are various types of 3d CNC milling machines that exist in the market. All of them are seen to be used for various purposes depending on the requirement of the application and the specification of the machine as all of them are for certain specific applications.

The Several types of Milling Machines that are there

There are various different types of CNC machines that are seen to be used out of favor and are now seen to be found only in the case of online advertisements. CNC milling machines are the type of machines that have encroached on most of the boundary that was once ruled by the machines that were being ruled by the other type of machines named drum milling machines, c-frame milling machines, and simplex milling machines. Among the variety of machines that are available, a few of them are as:

Vertical Milling Machines

These are considered the most commonly seen to be used type of milling machine that has a vertical spindle that is helpful in order to attach milling cutters to it in the form of end mills and face mills for various different types of milling operations. The machine is seen to be used for the machining grooves for the slotting keyways, it works in a way that produces flat surfaces and drillings, and boring holes as well. In the case of vertical mills, different types of cutting tools are seen to be used with the cutting edge in order to remove the materials from the workpieces that are usually made from materials like wood, metals, plastics, etc. Nowadays, these machines are seen to have a computer-based numeric control system which makes them known as the CNC, and can be operated automatically, manually, or both ways. The worktable of the machine moves both ways horizontally, left and right, in and out, and up and down as well, but it always stays perpendicular to the axis. In the case of some vertical mills, the table does not move up and down, ensuring the movement of the head of the spindle.

Horizontal Milling Machines

Usually, people call it a form of plain milling machine, but for most of the mechanisms, it is the horizontal milling machine, named because of the fact that the spindle remains parallel to the worktable instead of being perpendicular to the worktable just as it is in the case of the vertical mill. However, in the case of the vertical mills the machine is seen to move along the three axes known as the three-dimensional or 3d but the cutting tool will be mounted in a horizontal manner. Apart from the horizontal spindle the machine also contrasts with the vertical mill. In that case, it can use horizontal labor featuring a different type of cutting tools than vertical mills. Horizontal mills are far more rugged comparatively and are likely to work for a longer period of time for larger workpieces and perform rough cuts.

Universal Milling Machines

This is the most versatile type of machine that is known until now, these types of machines are capable of performing various different types of milling operations since they can be set up as horizontal; or vertical milling machines. In order to add to the versatility of the machine one could add furthermore attachments to it that are as an indexing head, slotting attachment, or rotary table. A lot of shops use these universal mills in order to produce tools like milling cutters, reamers, drills, etc.

Vertical Knee Type Milling Machines

These are the type of machines that are usually referred to as turret milling machines, variable-speed vertical milling machines, or knee-and-column milling machines. However, in the case of the vertical knee mills, the rotary cutting tool is used, just like in the case of like end mills and face mills in order to remove the materials from a workpiece. These types of tools differ from the lathe machines, where the workpiece is supposed to rotate, and a single-point tool is used in order to remove materials that are similar to a planer. These are the milling cutter machines that are held vertically, and the workpiece is supposed to be clamped in a way that it is clamped horizontally on the worktable of the machine. However, the table can be raised or lowered for the z-axis or the up-and-down movement.
