How to make cemented carbide tools more excellent

Carbide blades are composed of metal alloy powder, with more than 100 tons of press molding, and then through high temperature sintering. This is common with our top stone after long-term exposure, exposed to wind and rain, a large stone into numerous small stones and loose "weathered" process, so the alloy blade is very fragile, but also because of this principle.

 

To meet the requirements of a specific application, this product design not just adjust the number of cooling holes on blade. HPG provides a new groove, cemented carbide material - high wear resistant KCP15A material, this product is designed for steel material processing design. Compared with similar bit products, its latest design of self centering point angle and horizontal edge design can ensure the positioning accuracy and the hole verticality better, even in the case of high feed under. The slight chamfer fillet area of blade protection design, can reduce the edge chipping phenomenon, using the same design enhancement, HPG slot type products and therefore suitable for processing the hydraulic manifold application of common intersection and cable outlet, or processing heat exchanger in the production of stacked plates.

 

If the world only hole processing and application of steel materials, HPG groove blade should be sufficient to deal with, but the aerospace industry still needs processing of stainless steel and superalloy materials, automobile manufacturers of cast iron materials but also has a wide range of needs. For the former, the Kennametal Inc provides HPL slot type products, the design of split point of this product, can reduce the cutting force in the aerospace industry, medical equipment and materials processing alloy cutting long chips. And HPG is the same, this product also provides new materials, such as KCMS15, this is the fine grain cemented carbide material products a high abrasion resistance, corrosion resistant coating with AlTiN, can prolong the service life of the cutter. For cast iron, ductile iron and vermicular cast iron, four blade and round groove using HPC drill design, can avoid retracting common processing of these materials when chipping and cracking phenomena, the groove design of the special combination of rake face cooling hole design, the chip can be rapidly discharged.

 

All of these carbide blades adopt the drill point angle design of 143 degrees, through a special edge processing, polishing, or cutting edge rounding processing, ensure the optimization of tool life. The use of HPG, HPC, and HPL groove, KenTIP FS can be a variety of applications to meet the demand of the whole hard alloy drill processing, but its work unit cost is much lower, the performance is comparable or even better, Schmitt said.
