What is CNC Milling?

CNC (Computer Numerical Control) milling is one of the most widely used part manufacturing processed in modern industries.

In CNC milling, a multipoint cutting tool follows computer code to progressively remove material from a clamped workpiece to generate required shapes and contours. Wide range of metals, alloys and plastics can be CNC milled with high precision.

Almost all products require CNC milling at some point in their production because of CNC milling’s capability of producing accurate designs. The job of creating high-precision parts is one for state-of-the-art CNC mills.

3-aixs Milling

3-axis CNC milling is the most common type of milling process used in part manufacturing. Products with simple geometries that only require material removal in three directions are milled on 3-axis CNC mills with stationary tables for raw material and cutting tools that can move in X, Y and Z directions.

Prolean’s 3-axis CNC milling services offer economic prices for precision 3-axis CNC milled parts that all industries require in large numbers.


5-axis Continous CNC Machining

5-axis continuous CNC milling is the most advanced milling process used for manufacturing complex parts. Unlike indexed CNC milling where the extra two axes only change material position between operations, 5-axis continuous milling uses all five axes simultaneously which allows production of the most complex parts including the ones used in aerospace, robotics, automotive and medical industries.

Prolean’s skilled engineers and best-in-class 5-axis continuous CNC mills can produce your intricate parts with high accuracy.
