Let’s now give you some insight how Norck manufactures parts with CNC milling.

CNC milling (Computer Numerical Controlled milling) designates a process that uses a rotating instrument to remove material from a workpiece. It uses a computer to control the movement of the tool in 3 axes, hence the name 3-axis milling. In addition to controlling the tool, some CNC machines also control the workpiece by rotating it around its axis (4-Axis machine) or two axes (5-axis machine).

CNC milling offers more advantages over traditional machining methods:

   •   More accuracy: CNC milling offers tight tolerances, around ±0.0002mm
   •   Consistency: Since a computer executes the process, it minimizes human error.
   •   Faster fabrication: The fabrication process time is cut short because of the use of a computer to control the process. CNC milling can be used for rapid prototyping aswell as high-volume production.
   •   Lower production costs : The production cost is reduced because the operator has fewer interventions for controlling the tool’s trajectory and changes.
   •   Safer : The CNC machine has no access to the workpiece and tools when cutting the part.

There are several types of CNC milling operationa, including:

1.  Vertical Milling:
It is the most common process in CNC milling, where the milling tool (spindle) is mounted vertically. And it removes material by pressing against the workpiece. In vertical milling, the milling tool is long and thin.

This milling type makes holes, taps, grooves, and flat surfaces.

2. Horizontal Milling:

In horizontal milling, the spindle is mounted horizontally. The principle of horizontal milling is the same as vertical milling, with a fixed workpiece and a computer-controlled milling tool. However, the milling tool is shorter and thicker than the vertical. This type of milling is used to perform deeper shapes than vertical milling. And it is used for gears, grooves, and multiple sides machining.

3. End Milling (Face Milling):

In this process, the end part of the tool is used to remove material. It is used for profile, tracer, plunging, contouring, and reaming.
