Turning Ss 420 With Ceramic
The optimum solution for high speed turning of high temperature alloys.
Turning ss 420 with ceramic. These two new ceramic grades are characterized by their excellent toughness and anti chipping capabilities. Recommended grades and geometries are our stainless steel offer of cvd and pvd grades. Hard turning and milling. Turning is an almost ideal operation for ceramics.
Pdf metric pdf imperial features. Experimental results showed that the wear mechanism for ceramic cutting tool is predominantly abrasive wear and for cbn tools was adhesive wear and abrasive wear. High efficiency milling can be a very effective machining technique in stainless steels if the correct tools are selected. Ceramic s melting point 3 700 f is higher than sintered carbide which means it can be driven through the cut faster.
Turning austenitic stainless steels material classification. Speeds and feeds for turning stainless steels introduction. The abrasive wear is as a result of hard carbide particles in the. Austenitic stainless steel is the most common type of stainless steel.
This video shows the ability greenleaf have to turn 316 stainless steel using their highly productive ceramic inserts. Every insert has a melting point which reflects the temperature at which it is made. Turning inserts and grades for stainless steel. Aisi 420 stainless steel ss420 is a straight chromium martensitic stainless steel grade with certain wear resistance corrosion resistance and high hardness.
This paper describes the wear behavior of a ceramic and a pcbn cutting tool during the turning of aisi 440b stainless steels at different machining conditions. Choosing the right insert grades for stainless steel turning is crucial as these operations typically yield more friction and heat than many other materials. 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. Find the best insert grade here to ensure good chip control and long and reliable tool life.
The tables below give 420 stainless steel ss420 datasheet and specification including chemical composition properties heat treatment etc. The trial was on a doosan turning cent. Traditionally high speed steel hss tools have been used for most turning operations but carbide tipped tools are now also used. The choice of tool material depends in part on the required combination of speed feed depth of cut required production rate and volume and the available.
