POSITIVE CUTTING ANGLE REDUCES FORCES AND INCREASES CUTTING SPEEDS

Seco Tools Inc. releases a new MF4 chipbreaker geometry specifically designed to overcome the difficulty of consistent chip formation and breakage in stainless steel turning and other ISO materials.


Seco Tools Inc. releases a new MF4 chipbreaker geometry specifically designed to overcome the difficulty of consistent chip formation and breakage in stainless steel turning and other ISO materials. The main advantage of MF4 is its positive cutting angle, which significantly reduces cutting forces to allow for higher cutting speeds and increased productivity on the shop floor, and for longer tool life and lower energy costs for the front office. Additionally, the positive cutting angle also allows operating at lower temperatures, further adding to insert life. Seco claims that the MF4 geometry increases tool life by as much as 250%.

Although conventional turning inserts with a bumper shape in the nose perform well at standard feed rates and depths of cut, they tend to fail as cutting data increases. According to Seco, the highly secure edge line of the MF4 allows it to form and break chips very consistently, even when working in austenitic, martensitic or duplex stainless steels.

MF4 is available in three grades -- TM2000 and TM4000 for stainless, and TP2500 for steel -- all developed through Seco's new Duratomic coating technology where the crystal structure is actually manipulated at the atomic level. Additionally, MF4 is offered in TP3000 for secure operations in steel and CP500 for optimizing small components. A selection of different nose radii is offered as part of the standard insert program.
