VBMT Insert

CBN inserts excel when machining hardened steels and offer several advantages over traditional cutting tools, such as carbide inserts:

Hardness and Heat Resistance: CBN is the second hardest material after diamond, making it extremely wear-resistant. When machining hardened steels, which are particularly abrasive and cause rapid tool wear, CBN inserts can withstand the heat and pressure generated during the cutting process much better than carbide inserts.

High Cutting Speeds: CBN inserts can operate at significantly higher cutting speeds compared to carbide. This is particularly beneficial when machining hardened steels, as higher cutting speeds lead to increased productivity and reduced cycle times.

Longer Tool Life: Due to their hardness and resistance to wear, CBN inserts have a much longer tool life compared to carbide inserts when cutting hardened steels. This translates to reduced tool change frequency and increased efficiency.

Improved Surface Finish: CBN inserts can produce superior surface finishes on hardened steels, even at high cutting speeds. This is essential in applications where a smooth surface finish is a critical requirement.

Reduced Cutting Forces: CBN inserts require less cutting force during machining, which can lead to less stress on the machine tool and improved dimensional accuracy of the workpiece.

However, it's important to note that CBN inserts might not be the most cost-effective choice for all machining Cutting Tool Carbide Inserts operations. They are generally more expensive than carbide inserts, and their use is more suitable for cutting hardened steels and other tough materials, where their unique properties can be fully utilized. For softer materials or lower-stress machining applications, carbide inserts may still be a viable and more economical option. Proper selection of cutting tools depends on the specific requirements and materials being machined.
