Unique chip breaker design to ensure the best smooth cutting and chip flow control performance, reduce the formation of stress.Kennametal company's new type MR (semi-finishing and roughing) insert made the best chipbreaker type and material match scheme, excellent smooth cutting performance and wear resistance.

Someone say tools are the extension of human labor ability;So, tool maker is created for the common interests of human beings.In cutting tool product development, manufacture, performance optimization and other fields, kenner metal company has rich experience in 75.Kenner metal company latest Beyond ™ semi-finishing and roughing (MR) cutting blade products again for global manufacturers customers improve the production efficiency.

All processing workshops allover the world, each class turning more spare parts, or to achieve a longer service life of cutting tools is a common pursuit.This kind of products suitable for a variety of workpiece material processing, but is especially suitable for stainless steel material processing.Kerner metal company latest Beyond MR blade adopts the most advanced design, manufacturing process, and material technology, so it is the best cutting edges are smooth cutting performance and stable performance.So, this tool product in processing applications has the processing cycle is short, long service life.

"This product USES the best groove type and material of the coordination with the design scheme, thus has a better wear resistance and smoother chip control performance," kerner metal products design and research and development department senior director Dr Igor Kaufmann said.Double-sided indexable insert each side has four cutting edges, each cutting edge staggered position.A consists of entrance and exit of chip steps partition each cutting edge.These scraps steps help chip flow and the control of cutting action, but usually USES the incremental groove design of entry and exit in the cutting process is the part of the stress concentration, thus shortening the service life of the cutting tool

Beyond MR tool unique design is one of the features chip steps using continuous curved surface design, thus can reduce the formation of the alternating stress.Chip surface radius of the steps is very large, at first and then suddenly become smaller, and the entrance section of part, Kaufmann such explained.Starting from the chip level low, small radius of curved surface or increase, constitute the outlet section.Because the chip surface steps usually have a surface, thus can form uniform chip.In the steps of the chip, the chip will be continuous deformation, reduces the cutting tool chip surface friction.

Rake Angle refers to the cutting edge in contact with the chip on the surface of the top Angle, the strength of the size of the cutting force and cutting edge.Beyond MR blade design scheme using high positive rake Angle, cutting edge smooth surface can reduce the cutting force, prolong tool life."In terms of chip flow control, the advantages of this product is what products does not have before," turning senior product manager, Jan Andersson said.

　　Indexable double-edge blade cutting force under big cases, usually to cause a decline in strength.Beyond MR rake Angle profile to avoid the stress concentration point, therefore, even in cases of high positive rake Angle, still have the advantage of blade intensity.Even under the condition of large cutting depth application, turning process is safe and stable, and reduce the machine tool and workpiece on the load to bear.In addition, Beyond MR blade with internal cooling channels, the cutting edges can be efficient jet cooling.To ensure the improvement of the performance of the thermal control cutting process more smoothly, and prolong the service life of cutting tools.
