Why Are CNC Machines Used? Advantages of CNC over Conventional

The manufacturing industry relies heavily on CNC (computer numerical control) machines, including operations that once used engineer-operated equipment like routers, shaping machines, vertical millers and center lathes. The many CNC machine advantages mean operator-required equipment has in some cases been replaced entirely.

Here’s a look at the advantages of CNC over conventional machines, as well as a brief look at some of the disadvantages.

Advantages of CNC

  • No Need for Rest: CNC machines work around-the-clock and on weekends. They only stop working when they need maintenance or repair.
  • Scalability: When you enter the design parameters and specifications into a CNC machine, it can execute huge quantities – we’re talking about thousands of repetitions. These machines never need rest and you get incredible scalability.
  • More Capabilities: When used in tandem with advanced design software, CNC machines can create outputs that cannot be replicated by manual machines. Even the most gifted of engineers can’t do with conventional machines what advanced software can do with CNC machines.
  • Limited Supervision: It often only takes one person to monitor the work of several CNC machines. Given that these machines to so autonomous, one person can watch the machines work efficiently for hours on end after they’ve been programmed. What you save on manpower can be passed along to customers, helping you achieve a competitive advantage.
  • Uniformity: When you choose the advantages of CNC machines over conventional machines, your CNC outputs match exactly. Even the most talented engineers will produce components that vary slightly. Not so with CNC machines.

Disadvantages of CNC

  • Expense: CNC machines do cost more than conventional machinery. As mentioned above, however, an investment in the advantages of CNC machines means cost savings over the long term.
