Ceramic Vs Carbide Inserts

The surface of these inserts is very smooth allowing the chip to flow easily and prevent built up edges.

Ceramic vs carbide inserts.

Carbides such as tungsten carbides are made with tungsten carbide particles glued together with cobalt depending on type they vary with percentage of cobalt and size of carbides. Silicon carbide sic one of fuji s hardest and most popular insert materials. Sic has been advertised to even be able to handle light wire line. Sic can withstand any braided or super line without grooving.

It is commonly used on non ferrous materials including aluminum and magnesium alloys. Because ceramics do not bond as easily as other materials much higher temperatures must be used during sintering. However due to metal removal rates achieved the cost per edge is less than carbide. Solid carbide is extremely heat resistant and used for high speed applications.

Ceramic inserts are 2 3 times more expensive compared to carbide. Silicon carbide sic whiskers are often used to provide additional strength in ceramic inserts. For ceramic tools cvd coatings are the most common coatings starting from a dual layer system and going up to a multilayer system. Titanium diboride tib2 is a corrosion resistant ceramic compound made of titanium and boron.

B carbide table 2. It is a titanium based insert which is very light. Ceramic inserts are created in a process very similar to that used for cemented carbide. There are grades of carbide that will do 600 sfm and you re going to negatively affect the life of the insert by machining too slowly.

You are probably on the low end of speeds for a ceramic insert at 600 sfm. Do you need a high power or high speed machine tool. Here is a breakdown of some of the most popular ceramic inserts. Many shops waste money by tossing ceramic inserts prematurely.

The definitions of ceramics have changed greatly since early days. Tic tin or al 2 o 3 layers are the most common ntk cutting tools howard concurred that ceramic inserts are primarily cvd coated but the coatings themselves have a limited effect on overall performance. Ceramics are sometimes sintered heated to bond the particles without a secondary glue. Smith ceramic inserts show flaking along the cutting edge.

Normal wear patterns for reinforced ceramic inserts are unlike wear patterns seen on carbide inserts. High pressures are also used. Inserts used a ceramic.
