It is well-suited for industrial construction applications, electrical fittings, couplings, and structural fixtures. 6061 aluminum square tubing has excellent corrosion resistance to atmospheric conditions, responds well to anodizing, and is easily welded and joined by various commercial methods. ASTM-B221.
Jul 02, 2019· never used pcd, hss mills and drills it tends to stick to. getting ones made for aluminum helps, extra sharp and smoother polished flutes. got to watch drilling. anytime heat builds up and chips cant get out they can stick. needing a hammer and screwdriver to get chips stuck out of flutes is annoying obviously got to avoid heat buildup
Dr Baharudin et al. [1] applied the Taguchi method to fin out the optimal Ra of milling machine by the tool with HSS insert face cutting on material Al-6061. Pang et al. [2] focused on the ...
Jan 03, 2017· · A coefficient of friction value of 0.62 is obtained, which is lower than 1.02 and 0.8 of the carbide and HSS tools. When tested on an aluminum 6061 surface under dry condition, the SPB cutting tool is also able to produce turning finishing below 0.4 µm, beyond the travel distance of 3000 m, which is comparable to the carbide tool, but produces ...
6063 T5 Aluminum Square Tube. 6063 is considered the "architectural" grade within the 6000 aluminum series. Like 6061, 6063 has good corrosion properties, is easily anodizable, and weldable. However, 6063 is different to the extent that it's not as strong as the 6061 and consequently, will take a 90 deg bend without cracking.
Sep 01, 2018· The workpiece material used in this research is AL 6061-T6, the cutting tool used is HSS end milling with diameter 4 mm, and the mode employed is side milling. The experiment is designed according to the Taguchi method, and it includes sixteen samples.

When machining aluminum, one of the major failure modes of cutting tools is the material being machined adheres to the tool cutting edge. This condition rapidly degrades the cutting ability of the tool. The built-up edge that is generated by the adhering aluminum dulls the tool so it can no longer cut through the material.
