What is CNC milling?

CNC machining is a fast and reliable way to produce parts and prototypes using blocks of metal or plastic. There are various types of CNC services, one of them is CNC Milling. CNC milling is the process of cutting workpieces through a rotational cutting tool. It is one of the most common and widely used machining processes that allows for 3D design to be converted into physical parts. In a CNC milling machine the workpiece remains stationary whereas the cutting tool rotates around it making contact at various points to produce the desired shape.

What happens during milling?

To initiate the process, the workpiece or material block is fixed on a specially designed table so that all the details such as dimensions, planes and appearance are determined. Once through with this, the cutting tool approaches the workpiece to make contact with it. It removes the excess material by making successive cuts on the workpiece. This process is repeated until the desired shape is reached. CNC milling machines usually work on three axes which means that it would cut on three different sides of the material block. However, at Sacher, we also have machines that work on 5 axes. In such a case, the block does not remain stationary and is rotated to meet the design requirements.

There are multiple benefits of using CNC Milling. To begin with, milling machines can produce a diverse range of parts in different shapes and sizes. Therefore, you can make parts of any shape and size using a milling machine. This is advantageous for manufacturers that want to introduce prototypes or want to produce parts with intricate designs. In addition to this, CNC machines can also be used in the post-machining process to add details. This means that you can easily make changes in already made parts. Moreover, CNC milling is a fast, repeatable and inexpensive process. This is partly the reason that it is used to create rapid prototypes.

What can you make using CNC milling?

Some of the parts that are produced through CNC milling are as follows;

  • Fittings: fittings are used to connect two or more parts with each other.
  • Enclosures and Housings: housings and custom build enclosures are used to protect various components inside a machine.
  • Gears: CNC milling machines can be used to produce spiral and straight gears used in mechanical devices.
  • Engine parts: engine blocks and other parts are manufactured using CNC milling
  • Hydraulic equipment: CNC milling machines can produce parts such as water pumps with reliable impellers

CNC milling machines can handle a number of raw madterials such as common steel, stainless steel and aluminum to name a few. You can also produce parts using structural steel, hardened steel and spring steel. In addition to this, it can also work on magnesium, tungsten and cast iron. The only downside to CNC milling is that it doesn’t work great with round profiles and you might need CNC turning if you want round objects. At Sacher, we specialize in metal processing and have state of the art 3 axes and 5 axes machines. You can reach out to us using our website,
