london, United Kingdom (prHWY.com) June 22, 2012 - The activity of CNC machining is done by several different cutting tools. A milling machine is used for CNC milling and they are used when you need to machine solid materials. The CNC milling machines will generally be classed as either a horizontal or a vertical machining tool. This classification comes from the orientation of the main spindle on the machine.

The CNC milling machine is different from the basic drill press in the fact that the basic drill press holds the item being machined in a stationary position. This machine will move the material being penetrated by the drill bit radially against the miller cutter. The miller cutter will cut from the tip and will also cut from the side of the piece.

These CNC machining tools can be powered by different power sources. Some of them are manually operated machines, some are electrically powered machines, and then there are the digitally automated computer numerical control versions.

When these machines are being operated there is generally a cutting fluid pumped to the site of the tool. This fluid is necessary to cool the cut and to keep the material lubricated during the process. The fluid also washes away the swarf that is the result of the milling.

There are actually two subcategories of the vertical mills that are used to perform these actions. You will either be using a turrent mill that has a spindle that is stationary and the table moves perpendicular and parallel to the axis, or you will be using a bed mill that has a table that moves perpendicular to the axis but the actual spindle will move parallel to the axis.

Generally the decision to move horizontal mills or vertical mills is made due to the size of the piece of material that is to be milled. When it comes to cutting gears you will find the job is easier to do when you use the horizontal mill than with a vertical version, while die sinking work is primarily done with vertical CNC milling machines. The heavier and longer pieces that require milling are more apt to be placed on a horizontal machine.

These items can range in sizes from those small enough to accommodate the home workshop to ones that are large enough to fill rooms. They were primarily invented to reduce the amount of hand filing that is necessary when shaping precise pieces of rigid materials.

While there are typically the two basic classes for these devices there are several variants in the styles of them. Some of these include the following:
* Gantry mill
* Horizontal boring mill
* Jig boring mill
* Knee mill
* Column mill
* Bed mill
* Box mill
* C-frame mill
* Floor mill
* Planer mill
* Ram mill

A cnc machining http://www.slidinghead.com machine can be a vertical or a horizontal cnc milling http://www.slidinghead.com tool that is small enough to place on a tabletop, or large enough to fill an entire room.
