4 Products Created Through Precision CNC Machining

A CNC (Computer Numerical Control) machine uses pre-programmed computer software to run the equipment that uses tools–most commonly a router–to cut away material from a block of aluminum. These products can be for rapid prototyping projects or for final, consumer-ready products.

Precision CNC machining

Aluminum Heat Sinks

Precision CNC machining is one of the best ways to produce a quick turn prototype of a heat sink design, but it also can produce heat sinks that have extremely complex designs. These designs often show up in highly specialized projects where heat management is a big concern.

Some high aspect ratio heat sink designs are also common candidates for CNC machining as well as those with very long, thin fins.

EMI (Electromagnetic Interference) Shielding

Electromagnetic interference can disrupt the function of critical electronic devices, equipment, and systems at inconvenient–or even dangerous–times. Industries such as the medical, military, aviation and aerospace industries in particular need to have EMI shielding installed in these devices, equipment and systems to prevent catastrophic system failure or loss of life. The reliability of the equipment in these industries can be the difference between life and death.

Aluminum is an excellent material for the creation of EMI shielding because it is non-magnetic, corrosion resistant and has excellent conductivity. Machined aluminum is also lightweight and can be machined easily with a CNC router, precision metal stamping, and (sometimes) through aluminum extrusion.

LED Light Fixtures

LEDs produce a lot of heat and require unique designs to help manage that heat by radiating it away from the heat source. The nature of these designs makes using a CNC machine the quickest and best way of producing a suitable fixture for LED thermal management.

Spline Shafts

Spline shafts are metal rods that have splines, which are ridges or teeth that fit within matching grooves in order to transmit torque and rotation in a machine. The dimension for spline shafts must be accurate and one of the best ways to replicate near-perfect accuracy is through the use of a CNC machine.
