The unique groove design ensures optimum chip flow control and smooth cutting performance , reduce the formation of stress . Kennametal 's new MR -type ( semi-finishing , roughing ) blade geometries and materials using the best fit solution with excellent smooth cutting performance and wear resistance.

Some say that the tool is an extension of human capabilities labor ; therefore , tool manufacturers in the common interests of mankind and creation. In the tool product development, manufacturing , performance optimization and other fields, Kennametal has 75 years of experience . Kennametal 's new Beyond ™ semi-finishing , roughing (MR) product again turning blade manufacturers worldwide customers improve productivity.

In the processing plant around the world , turning more parts per shift , or for longer tool life is universal pursuit. This product is suitable for a variety of tool machining the workpiece material , but it is particularly suitable for processing stainless steel material. Kennametal 's new Beyond MR blade products using the most advanced design, manufacturing processes, and materials technology, so it has the best smooth cutting performance and stability of the cutting edge performance. Therefore , this tool products have applications in the processing of the processing cycle is short, long life characteristics .

"This product uses the best materials with the groove and design , it is more stable and better wear resistance and chip control performance , " said Dr. Kennametal's senior director of product design and R & D department Igor Kaufmann such said. Double-sided indexable inserts on each side have four cutting edges , each cutting edge position staggered . Comprising the steps of a chip inlet and outlet sections of each of the cutting edges separated. These chips steps to control the flow of chips and cutting actions are helpful, but usually the inlet and outlet sections incremental groove design is part of the stress concentration in the cutting process , thus shortening the life of the tool.

One Beyond MR tool is characterized by a unique design using a continuous surface chip level design, so you can reduce the formation of alternating stress . The radius of curvature of the first steps in the chip is large, and then suddenly becomes smaller , the inlet section and constitute a part of , Kaufmann explains this . Starting from the lowest point of the chip level , the small radius of curvature is increased, constituting part of the export segment . Because the surface of the chip usually has a surface step , thus forming a uniform chip . Steps in the chip , the chip will be continued deformation , reducing the chip tool surface friction .

Rake angle refers to the chip in contact with the end face of the cutting edge angle, the size of the cutting force and cutting edge strength influential . Beyond MR blade with high positive rake angle design, smooth surface of the cutting edge can reduce cutting forces , extend tool life. "In the chip flow control, the advantages of this product are not available prior to the product ," Jan Andersson , senior product manager said of turning .

Double-sided indexable inserts in the case withstand high cutting forces , usually cause strength. Beyond MR front corner contour avoids stress concentration points , and therefore , even at a high positive rake angle , the blade still has a large strength advantage. Even in the large depth of cut application conditions, turning the process is safe and stable , and reduce machine tool and the workpiece to bear the load. Furthermore , Beyond MR blade further includes an internal cooling passage , the cutting edge can be efficiently cooled jet . Improve the thermal performance of the control process to ensure smoother cutting and extended tool life .

"Every man-hours or more each tool capable of machining parts, this is indeed a problem plagued generations of metal processing operator ," Manuel Sedan Kennametal cutting tools , senior product manager said. "Improving the processing speed may cause the chip to set the time machine wound or remove swarf caused by prolonged and other issues. In addition, in the past a very long time , is an operator of a device processing mode. In the case of a single operator to manage a processing unit or piece of equipment , the tool should have better predictability and performance , which is essential to ensure the successful processing of applications is critical . Beyond MR tool can be applied to high-speed machining , machining parts to improve the amount of a single class , with excellent chip control performance, and long life. "

Beyond MR products are six kinds of materials can be used in a variety of stainless steel turning applications . It also provides material products for steel and cast iron materials processing .
