FY, SY Chip Breakers for Low Carbon Steel Debut

January 20, 2005
  After recently developing and manufacturing a new range of chip breakers for low carbon steel, Mitsubishi Materials Tools Corporation (President: Osamu Takata, Headquarters: 1-6-1 Yokoami, Sumida-ku, Tokyo) will launch this new range, called FY・SY breakers.
FY・SY   Low carbon steel that has high malleable properties is used as a pressing material for transmission and motor covers. Additionally, near net shape pressings that achieve a shape close to that of the finished product are increasing in use. Typically, these parts pressed from soft materials have minimal machining allowance making chip control difficult. Frequent machining problems include chips that wrap around work pieces or packing of tangled chips that can cause fracturing at the cutting edge.
  To solve these problems, Mitsubishi Materials developed the FY chip breaker for finishing and the SY chip breaker for semi-finishing. The use of these new chip breakers solves the problems caused by conventional breakers and helps maintain high productivity and reduction machining costs.

Key features of the FY・SY chip breakers are as follows

1.
The sharp wall of the breaker ensures good chip control. They can be used at a wider range of feeds when cutting low carbon steel than existing general use breakers, due to being designed specifically for this specialized purpose. They generate well-curled chips even from very soft materials such as iron plate, solving the various problems arising from tangled from chips.
2.
The rake angle is designed at the optimum level with a balance of sharpness and toughness. Because of a resulting low cutting force, these breakers can prevent vibration and deliver superior surface finish when cutting low rigidity applications.
3.
Standard grades available are PVD cermet VP25N and CVD coated UE6020. They can be used over a wide application range. The MIRACLE coating on the VP25N grade displays high welding resistance and delivers superior surface finishes. The tough UE6020 grade has a high fracture resistance and allows for stable cutting even when machining light interrupted cuts.
