May 09, 2013· • When milling cast iron, there's a lot more complexity involved when compared to turning the material. While the type of insert grade you use is important, it's even more critical to look at the total cutting solution. You must consider – in addition to insert geometries and grades – cutter body types and the number of cutting edges as related to your component.

Tool life for milling and drilling is less affected by CGI material attributes than cylinder boring, or any continuous operations. If milling cutters are selected that are of positive geometry and the right diameter to take advantage of the spindle power curves, then the …
The only drill bits you should not use to drill cast iron are those intended for wood or masonry only. Cast iron would completely destroy the the brad point and extra-wide flutes of a wood boring bit, and a masonry bit is designed to use with a hammer drill; it would take all day for the dull tip of a masonry bit to penetrate cast iron.

MILLING Standard milling cutters can be used, but smoother finishes can be obtained by using cutters with a higher helix angle of from 45 deg. to 52 deg. and with front or radial rake angles increased to about 30 deg., as in Figure 3 and Table II. Cutting speeds can be 150 sfm or higher, depending upon the rigidity of the equipment.
Cutting tool solutions that can correspond to the changing needs of the automotive industry. The automotive industry has been evolving rapidly in recent years through the new discovery of materials and technologies, prompting the need of sophisticated cutting tools capable of accommodating these new requirements.

Example: Calculate the speed and feed for a ¼ ″ HSS drill bit in soft cast iron on a manual milling machine in the lab. First, lookup the recommended surface speed (peripheral velocity) in
Milling machines can weigh anywhere from 15 to 5,000+ pounds. A micro mill has capacities that are a fraction of those of a vertical mill, but regardless of physical size, accuracy is built on a rock-solid foundation. Usually this is provided by a general structure of cast iron.
Milling is a cutting process that uses a milling cutter to remove material from the surface of a work piece. The milling cutter is a rotary cutting tool, often with multiple cutting points.As opposed to drilling, where the tool is advanced along its rotation axis, the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter.
Drill/Mill Cut Style These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for …

The work consists, fundamentally, in the machinability evaluation of three cast iron alloys, Compacted Graphite Iron classes 450 and 350, and Grey Cast Iron class 300, through drilling tests.
Milling cast iron. There are five main types of cast iron: Gray cast iron (GCI) Nodular cast iron (NCI) Malleable cast iron (MCI) Compacted graphite iron (CGI) Austempered ductile iron (ADI) Gray cast iron Material classification: K2.x. The dominant wear criteria when milling gray cast iron are abrasive flank wear and thermal cracks. On the ...

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.
