Why You Should Take Another Look at Shrink-Fit Tooling
An expanding array of design and connectivity options is making this tooling method faster and easier. This cost/benefit analysis shows why shrink fit’s benefits extend beyond mold-making and 5-axis machining applications.

With the right tools and CAM software, toolmakers and mold makers can keep production capacity flexible and will be able to ramp it up by up to 85% as they restart after the coronavirus outbreak. Hoffmann Group USA’s director of milling explains.
A conventional toolholder is supported only by the connection between toolholder taper and spindle taper. Adding a second connection – between the spindle face and toolholder’s larger-diameter flange face – resists deflection up to 40% in long toolholders.
The rules for twin-bore roughing and single-point fine boring are similar – but not the same. Lead angles close to 90 degrees more effectively combat potentially damaging chatter and vibration because they apply the least amount of radial pressure against the tool.
We recently had a question-and-answer session with Matt Panosh of SCHUNK to discuss the current trends and challenges in micromachining components for medical devices, surgical equipment and other related apparatus, and learn more about the technology many shops are using to compete in this environment.
Seco Tools’ Duratomic TM grades has thermal and mechanical properties as well as chrome-colored Used-Edge Detection technology to minimize waste. With new geometries and chipbreakers, three grades are tailored for distinct application demands.
Seco’s 335.18 and 335.19 cutters have close-pitch insert pockets to create stability. Meanwhile, a corrosion-resistant cutter body contributes to high performance when milling stainless steel, titanium and superalloys.
Seco expands its range of Jetstream tooling holders, offering 182 new products for all inch, metric and Seco-Capto holders. The internal coolant technology extends tool life while shrinking setup and indexing times.
