ASTM A519 Grade 1035 Material Machining Technology
ASTM A519 Grade 1035 can be machined using conventional methods. Generally, the material should be pre-heated to 150°C and then machined with high speed tooling. The machining of ASTM A519 Grade 1035 can be performed with a wide range of metal cutting tools such as drills, taps, reamers, end-mills, and countersinks. To ensure quality, tight machining tolerances should be observed, especially when fabricating components with complex geometries. Apart from this, it is important to note that some machining operations may require higher cutting speeds than the recommended rates. In such cases, it is recommended to increase the feeds and spindle speed, while also taking measures to cool and lubricate the cutting area.
