What is CNC and VMC: The Difference

CNC technology is a broad term for using computers to handle cutting, while VMC technology is unique to a type of CNC machine with a vertically positioned wheel. CNC technology is used for many things, such as milling, turning, cutting, bending, grinding, etc. By making industrial processes faster, more accurate, and more productive, both technologies have changed how things are made.

Even though CNC and VMC tools have some things in common, it is essential to know them. This blog post will give you a complete view of both technologies by examining how VMC differs from CNC Machines. After reading this, you’ll know how these tools are used in the current industry.

What is CNC Machining?

CNC machining is a subtractive manufacturing process in which material is removed from raw stock in an automated manner by a program of computer-generated instructions. Different types of CNC machines can be broken down into two groups: those that rotate the cutting tool while the raw stock stays still and those that spin the raw stock while it moves against a stationary tool. There are many versions of these basic methods; some tools use both to make items with complicated features.

What is VMC (Vertical Machining Center)?

Vertical Machining Centers, or VMCs, are a type of CNC machine built to do cutting work. There is one main difference between a VMC and other milling machines: the wheel axis of a VMC is vertical instead of horizontal. Cutting is faster and easier with this position, and the machine is smaller overall. Click it to view more.

Understanding the Differences Between CNC and VMC Machining

CNC (Computer Numerical Control) and VMC (Vertical cutting Center) cutting are two different ways things are made. It is more automatic with CNC milling, where a computer runs the tools to create things. The laptop has guidelines that tell it how to move, how fast, and how to go to get the desired effect.

CNC machines often do things repeatedly, like punching and cutting. On the other hand, VMC cutting is done by hand. The machine user uses a hand wheel or handle to control the tool’s movement, speed, and direction. The person running the machine has complete control and can make changes as needed to get the desired effect.

VMC tools often do more complex jobs like cutting and turning. The amount of precision is what makes CNC and VMC milling different. CNC machines are very automatic and only need a little help from people. On the other hand, VMC machines must be run by hand and require more skill and attention from the person running them. VMC machining is used for more complicated tasks, while CNC machining is used for functions that must be done frequently.

What Are the Benefits of CNC Machining?

These are some of the main reasons why CNC machines have become so popular:

1. Make items with very high levels of accuracy, always meet quality standards, and eliminate the chance of human mistakes.

2. Make parts 24/7, as long as they continuously get raw materials and new cutting tools. With robotic arms, raw materials can be loaded, and final parts can be unloaded without any help from an individual.

Advantages of VMC Machines:


VMC machines have vertical spindles that make it easy to get to the workpiece. This makes setting easier and reduces human tiredness.


Heavy-duty cutting can be done on VMC machines because they are stiff and vertical.

Space Efficiency: 

VMC machines are great for places with limited space because they take up little space but work very efficiently.

Reduced Cycle Time: 

Because their spindles are so fast and their tools can be changed quickly, VMC machines can cut cycle time by a significant amount.

Cost Efficiency: 

VMC machines are often less expensive than more significant machining centers, which makes them a good choice for many producers.

What Are the Applications of CNC Machining?

Woodworking Industries:

CNC machines are often used to make wooden furniture to save time and money. Carving wooden parts by hand takes a long time and costs much money. CNC machines can make furniture with complicated shapes that would have been impossible for a master woodworker to make by hand.

Electrical business:

Electronics needs CNC-machined parts for many uses. In the electronics industry, CNC machining makes holes for putting parts on printed circuit boards and heat sinks out of metal or copper for electrical parts that produce heat.

VMC Machine Applications

Because of its benefits and features, CNC vertical machining centers can be used in industries that need to make a lot of machines with high precision and low production costs. These include;

  • Aerospace
  • Automotive
  • Instrumentation
  • Light and Textile
  • Electronic and Electrical
  • Mold-Making
  • Military Products
  • Handicrafts Etc.

The VMC is best for working with complicated-shaped parts that must be processed in multiple ways.

Final Words

One type of CNC cutting machine is the VMC. Therefore, it is easier to understand the “difference between CNC and VMC machines” since VMCs are CNC cutting machines.
