By arranging the inserts tangentially, high holder rigidity is secured. Also,because the part subjected to the highest loads during machining is larger(S1>S2), it has great fracture resistance and can be used without worry for high efficiency machining.
The wide seating surfaces provided allow the insert to clamp on more firmly. Suppresses deviation of the insert caused by vibrations during machining.
Comments from developersDurability born through repeated destructive tests.In order to improve durability, we began development by first applying a load to the cutter until it broke. After analyzing the reasons it broke, we produced an improved version then broke that as well. We repeated this process until we were satisfied with the results. As a result of this pursuit of durability through thorough destructive tests, we were able to come up with a cutter that is ideal for unmanned operation and high efficiency machining. |
Comments from developersAn insert shape that was possible to design, but difficult to commercialize.The shape of the insert makes it tough while still enabling multi-cutting. It has been extremely difficult to move from the prototype, to maintaining a stable hape as a product. It is not an exaggeration to call this product, which has finally been commercialized through repeated improvements, the jewel of Mitsubishi Materials’ technology. |
