1 Solid Indexable PCBN s

2 Dear Business Partners and Customers We are delighted to present you with a catalogue of standardized cutting tools made of super-hard materials. You can find here solid tools of a PCBN (polycrystalline cubic boron nitride) manufactured by high-pressure synthesis directly in the company Bonar a.s., intended, first of all, for the heaviest roughing operations of difficultly machinable and heat-refined materials, as well as for final machining of these materials. We are also presenting basic characteristics and application overviews of individual cutting material grades including sample cutting conditions for representative workpiece materials. By opening this catalogue our concern for our customer s satisfaction does not finish. Full service ensured by our company includes: Consulting services while searching for a solution of a particular machining operation. That is our active approach at selection of a cutting tool, its geometry and manufacturing process conditions. Clamping devices, such as tool holders, washers and clamping system spare parts that we can supply to a selected cutting tool directly. Renovation of already used cutting tools is another service that is offered to our customers to make their production even more efficient either by resharpening or by replacement of a cutting edge. This service is also carried out on cutting tools that were not purchased in our company and on tools were a different geometry of the cutting edge is required by a customer as well. Other services include any cooperative services in the field of hard soldering, replacement of contact and conductive segments made of super-hard materials, resharpening, or dresser tip renovation, cutting super-hard materials by laser technology, etc. We believe that our products and services can help you to increase your competitiveness. 1 Solid Indexable PCBN s 2

3 Solid Indexable PCBN s PCBN MATERIAL PCBN (polycrystalline cubic boron nitride) is a highly efficient cutting material manufactured by high-pressure synthesis. High hardness (the second highest after the diamond), strength, wear resistance, toughness, high thermal resistance (c. up to 1200 C) and chemical resistance are specific properties in general, which means that there is no reaction with carbide forming elements included in the workpiece material. Nevertheless, these excellent properties, namely their extent, can also be changed. Basic variables for determining individual PCBN grades properties are PCBN content in a volume unit, a grain, composition and amount of a binder and applied sintering manufacturing process. Therefore, PCBN materials for cutting tools offered by our company are an obvious choice for machining of: hardened steels (from the hardness of 45HRc) bearing and tool steels for high-speed machining of grey and chilled-cast irons powder metals superalloys on the basis of Co, Ni, Fe Grades BRD 90 BRD 80 Characteristics includes 90% of CBN medium grain is 0.02 mm excellent abrasion resistance excellent resistance to chips to thermal and mechanical influence includes 85% of CBN medium grain is mm higher toughness and strength higher resistance to insert edge chipping others same as the previous A customer can machine the above mentioned materials either in standard accuracies, or the technology can be changed and the PCBN can also be used for finishing and replace grinding operations. However, the final operating power and workpiece machining quality is given by combination of all the applied attributes, i.e. PCBN properties, cutting conditions, a shape and a cutting tool geometry and a machine tool stability and toughness. A significant advantage for solution of different PCBN applications is a fact that a complete production is carried out by BONAR a.s. Thereby, there is a space for meeting customers requirements both in terms of dimensions and shape variability of products made of solid PCBN. 3 Solid Indexable PCBN s 4
