What are the different grades of carbide inserts?
Nano, Ultrafine and Submicron grades of carbide are what are generally used for end mills. They have a binder content in the range of 3-12% by weight. Grain sizes below 1μm have the highest hardness and compressive strengths, combined with exceptionally high wear resistance and high reliability against breakage.
How hard is PCD?
PCD is a composite diamond, 90-95% diamond powder + cobalt binder, therefore lower hardness than CVD. Around 6000 Vickers hardness.
How do I choose a carbide insert?
How to choose correct turning insert
- Select insert geometry based on selected operation, for example finishing.
- Select the largest possible nose angle on the insert for strength and economy.
- Select the insert size depending on the depth of cut
- Select the largest possible nose radius for insert strength.
What is C2 grade carbide?
C2 carbide C2 is used for milling tools where friction temperatures do not exceed 400 degrees Celsius. When dealing with metals like aluminum, a C2 carbide grade is used for roughing. When C2 is used in sawing, it is used to manufacture or coat steel rip blades.
What is the hardest grade of carbide?
NEW 5% grade
NEW 5% grade gives you the hardest grade we offer.
What is positive and negative insert?
The term positive and negative rake inserts refers to the angle between the cutting edge relative to the machined surface. If the cutting edge is equipped wiht a chip braker, positive cutting can be obtained even though the tool’s angle is negative.
What is CBN cutting Tool?
CBN tools are used for machining hardened steels because they offer a cost-effective alternative to grinding processes. Further applications are machining of cast iron and gray cast iron as well as cold and hot work steels. CBN is also increasingly used for machining of super alloys (nickel and cobalt alloys).
What is C5 carbide?
The tool has a C5 grade uncoated carbide tip, which provides good resistance to shock and wear for roughing and heavy machining of steel and steel alloys. These single-point tools have a cutting edge at one end that is a carbide tip brazed to a steel shaft.
