Machining Stainless Steel

That includes grade 304 and 316 stainless steel.

Machining stainless steel. Austenitic stainless steels are generally considered difficult to machine. The machined surface becomes harder at the same time as tool life decreases. The most common and hence most frequently machined stainless steels are the austenitic types such as grades 304 1 4301 and 316 1 4401. 303 stainless steel grade useful in making of nuts bolts screws gears shafts or many other machining tool.

These are characterised by their high work hardening rates and poor chip breaking properties during machining. The 400 series of stainless steel is easier to machine than the 300 series of stainless steel. Yor best will be to use an endmill that is tin or ticn coated with plenty of coolant to flush chips away. To minimize this avoid using tools with worn edges which could accelerate tool wear and cause breakage.

Some stainless steels are prone to work hardening during machining. This can have a negative effect on tool life and also reduce the life of subsequent tools used. Hsm is the best way to process 300 series stainless steel. Since our establishment in 2007 we are focused on machining stainless steels our advanced cnc machines inspection equipment and our expertise enable us to produce high performance stainless steel parts.

High efficiency milling can be a very effective machining technique in stainless steels if the correct tools are selected. Chipbreaker roughers would make an excellent choice in either 5 or 7 flute styles while standard 5 7 flute variable pitch end mills can also perform well in hem toolpaths. Helical solutions offers the hev 5 end mill which is an. Sulfur additions to the composition act as initiation sites for pitting corrosion.

Stainless steels for machining a designers handbook series committee of stainless steel producers american iron and steel institute 1000 16th street n w. In all machining that involves cutting austenitic and duplex stainless steels work hardening is more pronounced than in carbon steel or ferritic and martensitic stainless steels. With decades of experience a skilled highly trained staff and advanced cnc machining capabilities we can produce stainless steel parts and components at tolerances within 0 0005 or better. General principles of machining stainless steels introduction.

We specialize in resharpening carbide endmills for high speed machining with feed rates as high as 800 ipm in stainless. For high precision tight tolerance stainless steel machining look no further than portland precision manufacturing company. Make regular checks for signs of wear and change tools or inserts regularly.
