Seco Tools' JETI Toolholders Feature Interference-Free Internal Coolant Capabilities
Additions to Seco Tools’ JETI (Jetstream Integrated) toolholders are said to eliminate the components and connectors required for coolant-through tooling that hinder grooving, parting-off and other turning operations.
Additions to Seco Tools’ JETI (Jetstream Integrated) toolholders are said to eliminate the components and connectors commonly required for coolant-through tooling that hinder grooving, parting-off and other turning operations. With interference-free internal coolant capabilities and the option to switch the underside stream channel on and off, these expansions to the range of MDT (multi-directional turning), X4 (grooving and parting-off) and 150.10 (parting-off) toolholders add operational stability and reliability while improving surface finishes.
To optimize machining, chip control and process reliability, JETI tooling aims high-pressure coolant directly to the cutting zone through internal channels in the tool holder. JETI Duo incorporates upper and lower cooling channels with the ability to activate or deactivate the underside stream. Side and back coolant connections enable these holders to function on machines with conventional coolant delivery systems.
JETI enables application flexibility of coolant delivery without external hoses, fittings and spare parts that can diminish productivity and raise costs, the company says. Square-shanked MDT, X4 and 150.10 holders are available in sizes of 20 × 20 mm and 25 × 25 mm sizes. MDT holders accept inserts from 2 to 8 mm, and 105.10 toolholders accept size-15 blades.
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
The combination of a digital boring head integrated with tool data software dramatically reduces the time required to set up a fine boring head. And still more IIOT-enabled advancements are just around the corner that will finally automate many boring operations.
