Kennametal Fix8 Heavy-Duty Turning System for Maximum Metal Removal

Kennametal’s Fix8 heavy-duty turning system is designed to deliver maximum metal removal rates in steel, stainless steel and cast iron. With eight cutting edges per insert, the system is said to increase productivity of any heavy-duty turning operation, providing a low cost per edge while reducing cutting forces by as much as 15%.

Fix8 is designed to handle a range of applications, including turning and facing, smooth surfaces, interrupted and heavily interrupted cuts. The system can handle medium depth of cut to roughing in steels, cast iron and challenging materials such as stainless steel, the company says. It is said even feed rates of up to 1.4 mm (0.055") and depths of cut up to 12 mm (0.472") are possible.

The company says the tangential design of the Fix8 insert features a clamping system that pulls the insert securely into the pocket seat, offering stability that enables the insert to withstand large cutting forces and vibrations. The insert is also supported by a replaceable carbide shim, protecting the pocket against deformation and damage.

The system’s toolholder features precision 3D coolant technology, supplying sufficient coolant precisely where needed. Three coolant nozzles are directed to the rake face, while controlling temperature, chip evacuation and supporting chip formation. Coolant exit holes in two different locations are directed toward the flank of the insert, which is said to control the heat in the cutting zone and prolong tool life.

The insert design reduces cutting forces and power consumption, making it well suited for any low horsepower lathe, the company says.
