Difference Between CNC Milling Machine and Manual Milling Machine

>Difference between CNC milling machine and manual milling machine, Do you know their difference?

CNC milling machines have the same function as manual milling machines but they still have very different. In this article, we will detail the same and different differences before them.

If you are confused about this issue, then continue to look down.

Difference between CNC milling machine and manual milling machine

CNC milling machine are more versatile than manual milling machine. A number of jobs that are not possible with manual milling machine can be easily done with CNC mill.

• In a CNC milling machine the spindle is stationary and the table can move parallel as well as to the axis of the spindle for the cutting process. Where as in a manual milling machine the spindle rotates on its axis and the cutters are held in it.

• The CNC milling machine controls its movement by the numerical control controller, which makes his machining more precise. The manual milling machine is operated by manual operation. The result is that the error is very large.

• CNC milling machine can work 24 hours a day by writing programs, and no one is on duty. Manual milling machine needs manual non-stop operation, and can not achieve automation.

• Work done with CNC milling machine is faster than a manual milling machine so more work pieces can be made in less time.

• CNC milling machines can automatically change tools so that it is more efficient. Manual milling machines can only change the tool manually.

• The CNC milling machine structure is different from the manual milling machine. The CNC milling machine Z axis can move up and down while the manual milling machine is the work table moving up and down to complete the work.

• CNC milling machines can do a lot of work that manual milling machines can’t do, which is their biggest advantage.

• The standard CNC milling machine is a 3 axis linkage. We can also expand into a 4 axis and 5 axis linkage. Manual milling can only achieve 2 axis linkage.

• Because CNC milling machines use computer programming, even if they manufacture large quantities of parts, their size and surface are the same, manual milling machines can’t do this.

• Since the CNC milling machine adopts program control, one can operate multiple machines and the manual milling machine can only operate one machine.

• Ordinary people can operate manual milling machines, but CNC milling machines require trained engineers to complete the operation.

• Manual milling machines are more prone to errors than CNC milling machines due to the need for manual operation.

Summary of CNC Mill and Manual Mill

CNC milling machine principle

A manual mill has its table, spindle, quill and other parts moved by hand, requiring skilled use at every stage If good work is to be produced. A CNC mill has the axes and spindle, and often the tool changes controlled by a computer and a number of motors. It requires skilled programming only once, and changing out blanks and finished parts is an unskilled job, so CNC mills are very cost effective on repeat work.

Since feeds and speeds are tightly controlled they can be taken much closer to the tools upper limits of performance, again reducing the cycle time and improving productivity.

CNC systems can also make complex shapes using simple tools that would not be possible using a manual machine.
