Due to its superior efficiency compared to traditional manual processes, CNC machining is becoming more and more prominent in the manufacturing industry. The table below summarizes the advantages and disadvantages of CNC machines:
Advantages

Faster than manual machines

A CNC machine surpasses a human being in terms of speed, precision and accuracy. In large-scale production, the use of manual machines can only result in financial loss.

Reduced production costs

if the insertion and removal of materials and parts are properly automated; a CNC machine can technically run continuously day and night without supervision. Moreover, a single operator can manage several machines at the same time, which makes it possible to amortize the additional costs in terms of manpower.

Better efficiency

A CNC machine can switch from one operation to another in a fraction of a second. Some machines work with turrets on which many tools are already pre-installed, or libraries allowing the installation on demand of a tool in the spindle. Thanks to this, tool changes can be extremely fast.

Safer operation               

Manual machines can be very dangerous: even a highly skilled worker can make a mistake that will cost him a limb or even his life. Comparatively, CNC machines are very safe. The worst case scenario is probably that the machine ends up damaged due to bad programming.

Disadvantages

Expensive

A CNC machine is extremely sophisticated equipment. To be able to guarantee quality production, even after having already produced millions of parts, these machines are designed to meet very demanding specifications and tolerances. This is why they have a high cost.

Demand for highly skilled workers

Although their handling requires fewer workers than a manual machine, the complexity of CNC machines means that they can only be operated by highly skilled workers. Hence higher labor costs.

Higher maintenance costs

Due to their complexity, and compared to manual machines, the maintenance of CNC machines is much more expensive.
