Walter USA has launched Walter Turn Precision Coolant, a coolant delivery system that produces a direct coolant supply through the insert clamp and along the flank face of the insert resulting in a 30 to 150 per cent tool life increase, depending on the material and coolant pressure for stainless materials, high temperature alloys and steels, says Walter.
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 per cent 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 2250 psi. This range makes the system suitable for 95 per cent 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 4500 psi are also possible, especially for aerospace applications.
