Five Questions to Help You Better Understand CNC Machining

Are you curious which manufacturing method is the best for your products?  Do you want to choose a manufacturing technique that can work timely without compromising quality of your products?  CNC machining may be exactly what you are looking for your manufacturing needs.  CNC, or computerized numerical controlled, machines use a design on computer software to create a product.  These are a few questions that can help you better understand this process.

What is CNC machining?

CNC machining is a type of manufacturing process where a pre-coded computer program will instruct a machine to make movements and cuts in the creation of a product.  These machines run on digital instructions that are made by the programming specialists on special software programs that run G-code.  These machines work accurately to produce consistent, quality product parts or full products.

What are the types of CNC machines?

CNC machines come with different capabilities.  There are multiple machines that work to create different aspects of each product, such as:

  • CNC Drills – These machines use a rotating drilling bit to move it into contact with the stationary material being cut.
  • CNC Milling – These machines use a rotary cutting tool to separate the material being cut.  They also have tool shaping capabilities.
  • CNC Lathes – Lathes work opposite drills and milling machines.  They rotate the material to make the cuts in a circular path.  

These are just a few of the most common types of CNC machines, but you can find many different machines that offer a range of purposes in our shop.

How do CNC machines work?

CNC machines are controlled by a software program that is run by a professional who is trained in computer design.  These codes will then instruct the machines to make specific cuts, apply the right amount of pressure depending on the material being cut, and perform accurate functions with consistency.  At the end of the process, you will be left with a highly precise, high-quality finished product to use.

What is the ultimate goal of the CNC process?

When the computer program instructs the machines to work, its ultimate goal is to get the machine to draw out some portion of the metal to create the look and shape of the finished product.  This process aims to give the material its specified shape, like circle, square, rectangle, etc.  Skilled operators will work to ensure this process runs smoothly and the right shapes are being created.

Are there any other similar techniques?

One of the most common techniques that many people relate to is 3D printing.  3D printing also uses computer generated code to create products.  However, 3D printing will not be able to create products in any material, as there are more limitations with this process.  Also, it may not produce finished products with as high quality as CNC machining can do.

By answering these questions, we hope to have given you a better understanding of CNC machining and the process behind it.  If you are looking for a quality CNC machinist, contact Limea Precision to hear about our shop capabilities today.
