But, I actually was milling it. What happened is pretty obvious in retrospect. As the drill broke through, one lip caught on the side of the hole. Instantly, this converted drilling into milling as a reactive side load was imposed on the chuck taper. The sheet metal was thin, so the point of the drill was not restrained, and it exited the part ...

The machinability of ferritic and ferritic/perlitic nodular cast iron is very similar to that of low alloyed steel. Therefore, the milling recommendations provided for steel materials should be used regarding selection of tools, insert geometries and grades. Perlitic nodular cast iron is more abrasive, therefore cast iron grades are recommended.

it is not that the facemills i use cannot mill cast iron at 750-800 sfpm. they are being deliberately being run slower sfpm and at higher feeds .010 - .014" ipt to keep larger castings from distorting as much by running at cooler temperatures. parts i run are 40 to 96" long with a flatness and edge straightness of less than .0004" over those ...

The latest addition to our line of milling/drilling machines sports a dovetail column with a power feed. That's right! No more cranking the head up and down for tool changes or clearance, just push a button and save yourself the trouble. And there's more great features, too! A cast iron stand is supplied that has a coolant return trough.

Cast iron machining in a lathe or mill needs a very slow speed to cut it properly – too high and there will be sparks everywhere and your tools will need re-sharpening very quickly. As a general rule of thumb, to get a smoother finish on cast iron, you tend to need a finer tip on your cutting tool with very slow transition along the work.

Drilling cast iron is easy. It is a brittle metal that doesn't have much debris. The aforementioned heat-resistance and toughness make this material a top contender for at-home projects, so use it and drill into it without worrying about it breaking. Here are a few key takeaways from this post:

Trepan drilling with Paul Debolt. Boring large holes to diameter "takes too long and wastes material." Trepanning saves time and money! Not only does it requ...

An alternative to nearly dry machining, apply these coolants to tools before milling and machining to reduce heat with minimal cleanup. They're often used for shallow drilling, reaming, and tapping, as well as on saw blades.

The three principal machining processes are classified as turning, drilling and milling. Other operations falling into miscellaneous categories include shaping, planing, boring, broaching and sawing. Turning operations are operations that rotate the workpiece as the primary method of …
