Toolholders & Workholding

To ensure manufacturers can obtain the most productive machine for their particular part-production applications, United Grinding offers a full 360-degree range of Studer internal cylindrical grinding machines. This extensive portfolio of machines includes several universal-type models, as well as those designed for high production and for radii grinding operations.

Tungaloy introduces a new line of collet chuck sleeves for the TinyMini-Turn miniature boring tool system, enabling a quick changeover of its solid-carbide boring bars.

Jergens Inc. announces fixture plate machining kits and new receiver bushing plugs for its popular line of Ball Lock quick-change mounting systems. The machining kits consist of one fixture plate, four extra-long Ball Lock shanks and four spacers that provide clearance between the fixture plate and subplate below. This open space allows cutting tools to "break through" the fixture plate without damaging the subplate, making it possible to machine fixture plates while mounted to the same subplates they will be used with during production.

REGO-FIX offers a new cryogenic coolant technology based on the powRgrip system. Called CRYO-powRgrip (PG-CRYO), the system is produced in conjunction with a European supplier of carbon dioxide coolant and targets customer needs to boost productivity and eliminate secondary cleaning operations, especially for medical industry part-production operations.

Hoffmann Group USA announces the new centering vise called the GARANT Xtric. The vice is equipped with a new chuck jaw quick-change system, which enables easy, tool-free changeover. A click mechanism gives the vise an interchange accuracy in the micrometer range. Top jaws, which can be rotated by 180 degrees, allow for a large clamping range and high variability when fixing components. And clamping using multiple GARANT Xtrics is not a problem, the center can be adjusted precisely to achieve top precision.

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.

JW Winco Inc. announced it has expanded its line of GN 113.10 heavy-duty ball lock pins stainless steel, with stainless steel shank AISI 630. The GN 113.10 stainless steel rapid release pins have an extreme load capacity and are used for quick fixing, connecting and locking of various parts and workpieces.

As a recent addition to its EPPINGER PRECI-FLEX modular tooling system, EXSYS Tool Inc. offers a two-collet chuck that doubles the machining capability of one turning machine tool turret station. Designed for Mazak QUICK TURN and QTU series turning centers with optional high-speed drive motors, Y-axis functionality and standard BMT turrets, the double-collet chuck can deliver speeds up to 10,000 rpm with a 1:1 ratio and 20 N-m of torque and features 1,000 psi, or 70 bar, internal coolant.

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.

New additions to JETI (Jetstream Integrated) tooling from Seco Tools eliminate coolant-through tooling and connector interference that hinders 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 as required, these expansions to the range of MDT (Multiple-Directional Turning) X4 (grooving and parting-off) and 150.10 (parting-off) toolholders add operational stability and reliability while they improve surface finishes.

Weiler Abrasives has introduced its new line of CrossFlex honing brushes designed to provide machinists with performance and value for their professional honing applications. Available in small, medium and large diameters and with heavy-duty options, these brushes impart a surface finish free of metal burrs and are suitable for manual or automated use.

Kitagawa NorthTech Inc. introduces its new DKF Series of low-profile collet chucks. The DKF low-profile collet chuck features a compact nose, which is required when additional tool clearance is needed in tight workpiece and machining environments.
