The alloys which are nickel based and are good resistant of temperature and corrosion are considered to difficult when we are about to do machining of these. Still there are some conventional methods out there which can help you machining your alloys at satisfactory rates. Following are few key points which should be considered while machining inconel 600:- 1. Capacity - The most important factors on which the machining is dependent upon are speed, feed, depth of cut and tooling because these factors allow you to utilize machinery available for the job. Sturdy machinery is needed to to drill large holes and tapping . 2. Tooling - Alloys basic quality is being worked and because of this tooling needs to be changed or resharpen on regular basis. 3. Lubrications / Coolants - Coolants and lubricants should be as you desire. Water miscible vegetable oil can help you obtain good results. 4. Drilling - Make sure to use the same speeds (SFM) while facing, turning and boring for specific alloy as you do while using insert drills in CNC machines. Hope it helps. ----------- Thanks, James Root | Business Associate I love to talk anything about inconel mesh
