Types of CNC Machines. While the technology end of CNCs can be intimidating, the versatility of these systems makes the necessary learning worth it. There are several types of CNC machines, but there are at least six used in manufacturing and industry. Mills Based on a three-axis system, CNC mills utilize G-code or other unique languages.

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.

In a milling machine, stability is very important. If the material isn't stable during the cutting process, machining gears and threads or resurfacing likely will be clumsy and inaccurate. Look for a milling machine with a broad, heavy base, like cast iron, that won't shift or vibrate while the machine …

3. Knee-Type Milling Machine. The milling machine which has a knee like projection at the middle is called knee-type milling machine. It is characterised by a vertical adjustable work table resting on a saddle supported by a knee. 4. Ram-Type Milling Machine. A milling machine which has a ram on the top of the column is called ram type milling ...
