Characteristics of CBN turning plates

"CBN" turning plates, commonly abbreviated as CBN, are used for processing extremely hard materials. But what makes some of them more effective than others? What features improve tool durability and cutting conditions? We will try to answer these questions briefly.CBN as a tool material is obtained by mixing the main component of CBN (boron nitride with a cubic structure, second in hardness only to diamond) with a special ceramic or metal matrix. Then it is sintered under high pressure (several GPa) at a temperature of 1200 °With and above. CBN has excellent cutting performance, especially in high-speed processing of materials such as hardened steel, sintered alloys, etc.Types of CBN plates
CBN turning plates can be divided into two main types: solid CBN plates and carbide-based CBN plates. The use of "full-bore" plates is fully justified in intermittent processing with high cutting resistance and at high temperatures. On the other hand, CBN blade plates are ideal for operations where processing is stable and resistance is relatively low. This solution significantly reduces the cost of using CBN.CBN plates can be either coated or uncoated. Coatings, like conventional carbide inserts, increase durability and wear resistance. The latest technology of ceramic coatings allows them to be used in various types of processing.Trimming and smoothing edges
One of the most important features of CBN plates is the so-called honing. It acts as a protection for the cutting edge and the chip breaker. We can meet various types of honing, such as: radius, chamfer, chamfer with radius, etc. Certain types and sizes of honing are used for various applications, for example, "sharp" grinding works well in finishing, radius and chamfer grinding is devoted to roughing.It is also worth noting that CBN plates, like classic carbide plates, can be equipped with a Wiper smoothing edge. Smoothing the edge under the same conditions as with conventional jigsaws, but with increased feed, improves the surface quality of the workpiece. High feed rate not only reduces processing time, but also allows you to combine roughing and finishing operations.The above information may facilitate the selection of CBN plates for a specific application. Knowing about them will allow you to avoid the undesirable effects of mechanical processing, as well as save time and reduce the cost of production.
