CNC full form is Computer Numerical Control while VMC full form is Vertical Machining Center. CNC is a machine and VMC is just part of the machine. Now, let us have a deep insight into the comparison and difference between CNC and VMC.
Difference between CNC and VMC :
- CNC having two axis x and z whereas VMC having three-axis x,y, and z.
- We have to change the tool for different operations in CNC while an automatic change of tool is done in VMC. The tool changing process is done by a turret index in CNC whereas by ATC arm in the case of VMC.
- CNC most often used for cutting metal whereas VMC is very expensive and at the same time are very precise.
- CNC mainly used for turning inner and outer diameter whereas VMC mainly used for milling end and milling face.
- Geometry offset in CNC is z and x-axis and only z-axis is for VMC.
- The tool is rotated in VMC whereas not in the case of CNC.
- In CNC, a turret is worked as a tool holding and supporting device while Magzine is used for tool holding and a Spindle is used as a tool supporting device in VMC.
