CNC machining of precision cameras and projector parts

For CNC machining of aluminum parts with a large margin (large, thin-walled, aluminum cavity parts), in order to have better heat dissipation conditions during the machining process and avoid heat concentration, symmetric machining should be used during machining. If there is a 90mm thick aluminum sheet that needs to be machined to 60mm, if one side is milled, the other side should be milled immediately, and the flatness can only reach 5mm after processing to the final size at a time;

Turning and milling thin parts (aluminum, aluminum alloy, pure titanium, copper, magnesium alloy) are always prone to deformation during machining. Oval or “waist shape” with a small middle and large ends, which makes it difficult to ensure the quality of parts. Its clamping design is often the most discussed point. Let’s take a look at two design examples of thin-walled fixtures on turning and milling parts, and how they solve the deformation problem.
