Ceramic Vs Carbide Inserts

Made of ceramic particles bonded together with a nickel binder these tools are capable of running at higher speed than carbide tools and are much more wear resistant.

Ceramic vs carbide inserts.

Smith ceramic inserts show flaking along the cutting edge. The surface of these inserts is very smooth allowing the chip to flow easily and prevent built up edges. Whisker ceramic inserts are for moderate hardness machining at high surface speeds. Sic can withstand any braided or super line without grooving.

It is a titanium based insert which is very light. The definitions of ceramics have changed greatly since early days. 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. Many shops waste money by tossing ceramic inserts prematurely.

Because ceramics do not bond as easily as other materials much higher temperatures must be used during sintering. Silicon carbide sic one of fuji s hardest and most popular insert materials. Ceramic inserts are created in a process very similar to that used for cemented carbide. 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.

Sic has been advertised to even be able to handle light wire line. It is commonly used on non ferrous materials including aluminum and magnesium alloys. You are probably on the low end of speeds for a ceramic insert at 600 sfm. Solid carbide is extremely heat resistant and used for high speed applications.

Silicon carbide sic whiskers are often used to provide additional strength in ceramic inserts. Ceramic inserts are 2 3 times more expensive compared to carbide. High pressures are also used. Here is a breakdown of some of the most popular ceramic inserts.

However due to metal removal rates achieved the cost per edge is less than carbide. Normal wear patterns for reinforced ceramic inserts are unlike wear patterns seen on carbide inserts. Titanium diboride tib2 is a corrosion resistant ceramic compound made of titanium and boron. For ceramic tools cvd coatings are the most common coatings starting from a dual layer system and going up to a multilayer system.

Inserts used a ceramic. B carbide table 2. Ceramics are sometimes sintered heated to bond the particles without a secondary glue.
