Machining copper heatsinks and aluminum heat sinks using high speed CNC machining centers from DATRON

Copper Heatsink Aluminum Heat Sink Milling


Milling copper heat sinks and machining aluminum heat sinks is an ideal application for DATRON high speed CNC milling machines because copper and aluminum are the perfect materials for high speed machining. Our high speed spindles (up to 60,000 RPM) allow for exceptionally high feed rates in copper and aluminum and this reduces the overall cycle time when machining copper and aluminum heat sinks. The small tooling and high RPM used in these applications yield less machining force and the manufacturer is able to mill particularly thin walled parts with superior surface finish without the need for secondary operations like de-burring or degreasing. That's because the coolant used for copper and aluminum is not oil based and simply evaporates leaving clean burr-less heat sinks. Other unique DATRON features include:

Heat Sink Machining Centers:
The M8Cube has a 40” x 32” x 9” work area with ample room for various workholding setups like pneumatic clamps, vacuum tables and even a trunnion-style 5-axis system. Precision-ground ball screws, linear guides and brushless direct drives provide superior accuracy in all axes. Optional XYZ probing recognizes irregular surfaces and compensate for them dynamically.

The M10 Pro is our fasted most accurate machine with linear scales for high position accuracy across the entire work envelope (ISO 230). With a 41" x 35" travel the M10 is capable of rapid rates up to 30 meters per minute. When the shortest cycle times or mirror finish surfaces are required, the M10 is the way to go. Plus, the liquid-chilled, 40,000 RPM spindle is exceptionally suited to rapid, high-volume material removal. The solid granite table adds rigidity for precision milling.

Now, if an extremely large work area is required, as is the case for batch milling a run of aluminum or copper heat sinks, the MLCube is a large format milling machine that is ideally suited. The 60" x 40" travel of the MLCube can be equipped with a QuadraMate Vacuum Table to hold large sheet material up to 24" x 36". Aside from the large machining area, the specifications for the MLCube are similar to the M8Cube.
