Walter has introduced Walter Turn Precision Coolant, a powerful and targeted coolant delivery system that produces a direct coolant supply through the insert clamp and along the flank face of the insert. The result is said to be a 30- to 150-percent increase in tool life (depending on material and coolant pressure) for stainless materials, high temperature alloys and steels.

The new system directs coolant precisely at the cutting edge providing greater lubrication, cooler inserts, and improved chip control, beginning at pressures as low as 150 psi. The positive effects increase with pressure, particularly at pressures above 580 psi. This can result in cutting speed improvements of up to 100% while maintaining the same tool life. Along with greater productivity, this improves surface finish with less peripheral zone work hardening, and boosts process reliability. Energy efficiency also benefits from the precisely targeted Walter Turn Precision Coolant system.

The new system is aimed primarily at ISO material groups P, M and S, with a pressure range of 150 to 2,250 psi. This range makes the system suitable for 95% of all machines in use today.

The new coolant delivery system features three coolant connection points: coolant hose connections at the back of the tool and under the head, and a direct coolant transfer port for VDI connections. Higher pressures up to approximately 4,500 psi are also possible, especially for aerospace applications.
