CNC Precision Machining Pros and Cons

CNC precision machining is a particular type of equipment that relays on computer software to plot coordinates and cut items accurately according to the plotted coordinates. With this machining, each item is made precisely the same way. That is because the cutting machinery moves to the same exact coordinates in the exact order time after time.

If you are looking for an equipment piece that can produce few identical items or thousands of them, CNC precision machining is your best option since it can deliver fast and consistent components. Due to the numerous advantages it offers, CNC precision machining is a popular choice among the industry. However, like with any type of machining, there are few disadvantages as well and you should know them before your purchase.

Precision Machining

CNC Precision Machining Pros

  • Precise results – components are produced to the same exact specifications, and the result is identical parts with minimal variations.
  • Less skilled labor – Taking the fact that a computer controls machining, you avoid the need for many skilled engineers to run manual lathes and milling machines. Actually, a single skilled operator can supervise various CNC machining running at the same time.
  • On demand prototyping – With a CNC precision machining designing and producing a prototype on demand is pretty possible. This can minimize your modeling and prototyping costs.
  • 24/7 operation – A CNC machining can take a 24/7 working chore with minimal downtime for maintenance. On the other hand, manual machining may need frequent breaks, highly skilled labor and shift work.
  • Complex production – The advanced software used by this machining allows the production of complex parts that are impractical and even impossible to produce using manual labor.

CNC Precision Machining Cons

  • Higher price – CNC precision machining equipment is not cheap, and buying it will require a larger investment than buying manually operated machines.
  • Reduction in workforce – Fewer skilled engineers are required to run CNC machines so, turning to CNC machining means a reduction in your workforce. While some business owners see this as a benefit, others (those who value their employee) take it as a disadvantage.
  • It can discourage students from learning other engineering skills – That is because manual equipment is becoming less commonly used and only a few students are considering manual machining skills.

It is important to mention that both manual machining and CNC precision machining have their place in the industry. However, CNC machining is a much more precise technology with various advantages over manual process. Consider the pros and cons of the machining to find out if its suitable for your application.
