CNC Machining Services – CNC Milling and Everything You Need to Know About it


CNC machining is one of the most important services contracted around the world these days to get products or parts manufactured using metals or polymers. While is not exactly needed that you understand how CNC machining works it’s really useful if you are able to handle a few basic bits of knowledge. We can offer a brief introduction about milling over the next few lines to get you introduced into one of the most requested CNC machining services in the industry.

What is CNC Milling and How it Works?

The basic principles behind CNC milling are the use of a rotating cylindrical tool that makes his way through most materials by managing certain types of cuts and perforations. The main difference with basic drilling is that the milling machine can move from three to five different axes that allow the tool to create shapes as well as the holes and sloths needed according to specifications of the design. The range of motion of a milling machine goes beyond the single 90° of basic drills.

As you can probably imagine by now the complexity of the process, make it a bit more expensive than regular milling, but the fact is that the companies using this technology are saving money since they don’t need to go through various molding processes to get the parts being manufactured done with accuracy. The technological advancements of CNC milling are able to offer modern machinery that can do the job in a single sitting.

Here are some of the basic components needed on modern CNC milling machines to get the job done in more efficient fashion, as well as the logistics handled on each of them.

·       Main Control Panel

This first step interface is where the human hand of a technician will be able to input all the code required to do the job. The code is just an ephemeral way to call all the measuring and engineering data required to make the parts properly with the equipment. While the CNC milling is prone to an occasional problem in performance, any mistakes on manufacturing will most likely be consequences of poor planning.

·       Table and Column

The Table is the receiving end of the machine holding the product being developed. It’s usually resistant enough to handle most materials and is fitted with T-slots and clamps. The column gives full support to the machine and serves as a backbone for the milling part.

·       The Cutting Tool and the Axes

This is the main manufacturing component. The cutting tool is placed in the column and is the one that gets the shapes done while moving the axes according to the instructions offered on the software.

·       Frame and Spindle

The frame is probably the most visible part of the CNC milling machine as it provides all the support and rigidness needed for the equipment to be able to do its job without making a mess. The spindle is the part that manages all the rotation angles of the cutting tool, and it’s attached directly to the motorized parts of the machine.

·       Coolant Supplier

The final part of the machine is where the products delivered is cooled down and released from manufacturing. The system is also tasked with constantly lubricating the cutting tool to make it work properly at all moments.

With this basic guideline, you will be able to understand just how much work goes with each CNC milling project. It’s also useful to realize how important is to have a clear idea of all the data related to it done properly.
