Threading Shank Holders Deliver High-Pressure Coolant to Cutting Edge
Seco Tools introduces Jetstream Tooling high-pressure coolant technology for threading shank holders. The range includes shank holders for external applications, boring bars for internal applications and GL-heads for use with the company’s Steadyline boring bars.
The thread-turning holders deliver a concentrated, high-pressure (up to 3,988 psi) jet of coolant through a hose connection to the optimal position, close to the cutting edge. Unlike flood coolant, high-pressure coolant can penetrate the heat vapor barrier that develops on a cutting tool and workpiece in the cut zone. This technology can also be used to guide or steer chips away from the cut and increase tool life, even with minimum coolant pressure.
The holders are capable of breaking tough threading chips on parts made of titanium and similar materials, increasing tool life. When threading steel and stainless steel, the improved chip control can increase cutting speeds by as much as 60 percent without compromising thread surface quality, according to the company.
The thread-turning holders are available in 16 external, 28 internal and 14 GL-head types in insert pocket sizes 16, 22 and 27.
Angle heads can enable a three-axis machine tool to be more versatile. That said, this shop explains that there’s more to getting started using them than simply loading them into a machine’s spindle.
A system to be marketed in 2015 will apply ultrasonic vibration from within the toolholder to reduce cutting force and improve the performance of the cut.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
