What is the difference between CNC and VMC?

There is no difference between the CNC and VMC.

CNC stands for “Computer Numerical Control” While VMC Stands for “Vertical Machining Center”

Difference is in between VMC and HMC.

A VMC and HMC is a machine with a CNC controller.

CNC is Computer Numerical Control which controls the machine operations.

i.e. Turning Centre(Lathe), Milling, EDM, WEDM, Laser Cutting, CMM.

VMC stands for Vertical Machining Center.

HMC stands for Horizontal Machining Center.

In VMC, The work piece is hold on the table base and the spindle which contains the cutting tool is fixed on vertical spindle Z axis. The table moves in X and Y axis and spindle with cutting tool moves in Z axis.

In HMC, spindle rotates in a horizontal orientation in which cylindrical work piece is rotated around its axis and tool is stationary and all controls are controlled by the CNC controller. i.e. Turning Center is HMC.

By means of Computer Numerical Codes the work piece is cut in particular shape in VMC and HMC.

CNC is a type of motion control system. It basically means that instead of using cams or templates to cut a part, it is controlled by a computer.

A VMC is a type of CNC machine, typically enclosed and most often used for cutting metal. They are usually very precise and very expensive. Here is a pic of a popular VMC, built by Haas, that uses CNC controls.

So there is no ‘difference’. One exists as a specific type of the other. A modern VMC is controlled by CNC. The CNC is the computer and motion part of the machine. The rest is the frame and the spindle (cutting head). In addition to VMC, CNC technology can also control lasers, 3D printers, water jets, plasma cutters, saws, etc…
