Ceramic Cutting Tools Materials

Polycrystalline cubic boron nitride cbn is a cutting tool material with excellent hot hardness that can be used at very high cutting speeds.

Ceramic cutting tools materials.

Interest in ceramics as a high speed cutting tool material is based primarily on favorable material properties. Can i cut this with an endmill. The solution is to use ceramic inserts. From the back cover ceramic cutting tools is the first practical book on ceramic cutting tools to appear in twenty six years and breaks new ground in a way that previous books did not.

Two types of ceramic cutting tools are available. Hence they can be used at high cutting speeds without deformation or dissolution wear processes determining tool life. Modern cbn grades are ceramic composites with a cbn content of 40 65. If not can i use one of those little dremel grinding tools for the ceramic part.

Ceramic tools are chemically inert and possess resistance to corrosion. They have high compressive strength. Most common ceramic materials are aluminum oxide and silicon nitride. Powder of ceramic material compacted in insert shape then sintered at high temperature.

They are hard retain their hardness at high temperatures and have a relatively low reactivity with steel. Alumina based and silicon nitride based ceramics. According to steve howard marketing and engineering manager for ntk cutting tools usa wixom mich sin based ceramic grades such as ntk sx6 and sp9 have twice the fracture toughness of alumina based ceramics. The alumina based ceramics are used for highspeed semi and final finishing of ferrous and some non ferrous materials.

It also exhibits good toughness and thermal shock resistance. The silicon nitride based ceramics are generally used for rougher and heavier machining of cast iron and superalloys. Ceramics as a class of materials have always had potential as cutting tools.

Recent developments in ceramic cutting tools materials and machining methods have greatly improved aerospace component manufacturing. This level of toughness enables turning and milling cast iron at speeds up to 3 000 sfm. Each part has 4 pockets 466 dia x 300 deep in alum. Ive never cut this material or ceramic in general.
