Types Of Aluminum Machining! The manufacturing industry aluminum can barely cope without aluminum. Below are a few machining types with high speeds used in the industry. 1. Machined Aluminum Prototype Machined aluminum prototypes are mainly products of a variety of alloys. The commonly used alloy is 6061-T6, covering transportation, aerospace, electronics, and military industries. Aluminum alloys have high strength and low density. Most time, Aluminum CNC machining has a high tolerance to control as much as 0.01MM. Quality and unique aluminum equipment can be manufactured via CNC. The perfect choice for this process is CNC Milling, and it has high accuracy and precision in milling aluminum. Prototype manufacturing in aluminum takes several processes from aluminum blocks. Wide range of technologies and machines come up with the best tool design for each equipment made. Designers and manufacturers tend to launch their products In the shortest possible time frame to save cost. A sample close to the original will be manufactured.
