Chucks & Jaws

U S Shop Tools offers round jaws in sizes up to 28 inches in diameter. In addition, large diameter steel round jaws, up to 15" with a height of 6", are also available.

When EMAG launched the new TrackMotion automation system in 2015, it quickly became apparent that it not only focused on transporting parts, but on the perfect combination of machine tool, raw parts storage facility and a standard automation solution to create a highly efficient production line. The consistent adjustment of the automation to the modular machines from its internal production makes it possible to create manufacturing systems using a modular kit. So it will come as no surprise that EMAG is now unveiling another world first, a direct development of the modular machines in combination with the TrackMotion automation system – the VL 3 DUO.

A customer came to Northfield Precision Instrument Corp. to design a chuck that would allow its precision sprocket to be positioned in the chuck only one way in order to assure a properly timed gear part. It would have to work with a range of gear diameters. Northfield's engineers customized the NF-650 air chuck with special tooling to meet these requirements.

With total monitoring feedback, a maximum clamping power of 20,000 N and enhanced precision, the new MTS 2.0 (Modular Tooling System) fulfills even the most exacting machining demands. The use of state-of-the-art ceramic lock balls combined with innovative springs increase clamping power while allowing an opening pressure of only 6 bar.

INDEX has developed a new generation of its turn-mill center G200, a compact machine that offers higher performance, potentially up to 30 percent greater productivity, in the same footprint as the earlier generation. The redesign of the machine resulted in an increase of the maximum turning length to 660 mm, a higher performance milling spindle and expanded live tool complement, as well as the XPanel with i4.0 readiness.

RÖHM Products of America now offers a powered external clamping chuck for gear surface face grinding. The KZF-S collet chuck is especially well-suited for clamping gears/workpieces that have an external plane or gear teeth geometries accessible from the outside.

BIG KAISER has launched the HMCJ, a super-slim milling chuck with peripheral coolant supply, designed to support heavy-duty and finish endmilling tasks with power and precision using Ø1/2" or Ø12mm cutters. The newest, slimmer member of the Hi-Power Milling Chuck (HMC) family features a clamping bore with fine slots surrounded by hundreds of needle bearings, which ensures concentric, precise and smooth clamping when the nut is tightened.

Northfield Precision Instrument Corp. designs and manufactures of precision workholding chucks. When a good customer required a chuck to hold parts to be mounted to a Studer grinder for contour grinding into special cutting tools, it turned to Northfield for help. Northfield's engineers customized the Model 650 chuck to use only one jaw for clamping.

Makino has created a new 5-axis version of its V33i hard milling vertical machining center, the V33i-5XB. The V33i platform provides extreme dynamic accuracy for long hours of continuous hardmilling, and the new 5-axis capability provides for reduced part setups and extreme accuracy in contoured shapes.

Doosan Machine Tools America offers its latest generation of advanced multi-tasking turning centers: the PUMA SMX series. There are six models in the line, stepped in size and capabilities. Most offer the configuration of equally sized and powered left and right spindles plus a B-axis milling spindle.

Okuma says its new GENOS L3000-M one-saddle lathe is strong, fast and ideal for cutting a range of exotic materials with ease. The integral spindle motor provides increased machining capacity and rigid guideways handle powerful cutting capabilities.

Makino announces its latest full 5-axis machine solution, the DA300 vertical machining center, reportedly providing the ideal blend of speed, precision and flexibility for complex part applications. Inspired by the best design characteristics from both vertical and horizontal machine platforms, the DA300 delivers the highest productive capabilities for multi-axis workpieces in the smallest of machine footprints.
