Toolholding & Workholding

High-speed machining — in excess of 20,000 rpm — often is used in aerospace when machining exotic alloys and hard metals, such as titanium. At these speeds, precise, secure seating of tapered toolholders in the spindle becomes even more critical. Failing to pay attention to this single detail can lead to decreased productivity, less precise machining, reduced tool life and damaged workpieces.

Vibrations, chatter marks, tool failure – what has so far robbed many a machine operator of sleep will soon be a thing of the past: With the smart iTENDO hydraulic expansion toolholder, SCHUNK and startup company TOOL IT present an intelligent toolholder that monitors the machining process directly at the tool, and allows real-time control of the cutting parameters.

The new Kurt Pyramid workholding platform is designed to attach three Kurt vises for 5-axis machining multiple parts in one load. The 45-degree vise mounting surface is positioned so each vise provides maximum access to all machined surfaces and allows for enhanced spindle and cutting tool clearance.

GTI Predictive Technology announces its newest innovation in wireless route data collection.

Setco's TensionSet is a load-limiting device that ensures proper belt tensioning on motor drives, protecting shaft bearings and other components from premature failure. The patented and easy-to-install product rotates like a nut to generate pull-force on a threaded rod.

Kennametal answers with turret-adapted clamping units and quick-change toolholders.

The uniquely shaped combination bench and pipe vises from Palmgren feature a straight line pull design and super strong power tunnel to assure that the spindle and nut never wear out. As a result, this design delivers increased clamping power and reduced drag enabling the vise to easily open and close.

CTE Owner and Publisher Dennis Spaeth made the rounds at EASTEC 2019 talking with some of the great companies we cover, like Koma Precision, Inc. Here, Adam Rosen provides an overview of Koma's new Prime Tool Presetter machine.

Global demand for toolholders, specifically arising from the automotive and defense and aerospace industries, will witness a relatively steady growth through 2028, as predicted by Future Market Insights (FMI) in its recently released market intelligence report.

Metal working facilities constantly strive to reduce machining times, and saving a minute or two here or there can really add up. According to John Zaya, workholding product manager for Big Kaiser, time savings can be achieved using flexible workholding systems.

Dillon full grip jaws, machined from 6061 extruded aluminum for increased strength, are now available up to 28-inches in diameter. Machining from bar stock eliminates the porosity inherent with large-diameter aluminum castings, providing a stronger and more reliable workholding product.

The Heavy Duty T-Slot Clamps are capable of generating over 20,000 pounds of pressure. This design utilizes some of the strongest, lowest-profile clamps in the industry, including the Pitbull and OK-Vise Clamps.
