Chucks

Reaching deep inside a workpiece to drill holes can be a real bear. You’ve tried taper length and aircraft drills, but even those made of solid carbide are apt to wander when hanging out of the chuck unsupported.

Dillon Chuck Jaws introduces an 18”-dia. boring ring. Its relatively light weight allows customers the same ease boring out 18”-dia. blank top jaws as is had when forming smaller diameters using the smaller boring rings.

The idea of designing drills for higher feed rates by adding a third cutting edge is nothing new. However, due to the challenging chip evacuation, these tools have so far only been suitable for a few applications, such as machining cast iron. With a new design, the Hoffmann Group has now succeeded in harnessing the advantages of the three-flute drill for long-chipping steels and stainless steel materials.

In many technical fields, ultrafine grinding is one of the tasks that gives the product its final polish – in the truest sense of the word. This applies equally to both precision and the visual appeal. SUHNER offers an innovative grinding, milling and polishing system, SUNmic 60.

With the new VM 9 modular turning machine, EMAG has introduced a platform that covers a broad spectrum of applications thanks to the combined turning, milling and drilling technologies and intelligent machine design. The highly accessible machining area and workpiece spindle fitted at the bottom ensure short tooling times and maximum flexibility in the production of workpieces in small series.

To better serve its customers, RÖHM Products of America has made significant investments in its ability to offer comprehensive chuck repair and rebuild services at its Suwanee, Ga.-based headquarters, as well as onsite at its customers’ manufacturing facilities across the country. In doing so, the company creates a one-stop shop for all chuck service needs.

Nowadays, more and more products are being manufactured from stainless steel and higher and higher requirements are being placed on the surface finish of these products. In the process, a problem has appeared that does not seem to be spectacular at first glance, but ultimately causes high costs: extraneous rust.

LMC Workholding offers the Energy series large-bore air chucks, featuring a built-in air cylinder and extra-large through-hole. The full spindle bore of the lathe can be utilized for through-hole work and long jaw travels provides more clearance for through feeding pipe.

Thanks to their outstanding tool lives, fine surface finish and maximum concentricity, hydraulic chucks found their place in milling. And there is good reason since these chucks offer both continuous action of the cutting edge and excellent vibration-damping properties. Fitted with such a lot of positive features, hydraulic arbors and adapters are suitable for the range of products of POKOLM Frästechnik GmbH & Co. KG.

Doosan Machine Tools America presents the PUMA 1000/M, which was specifically developed for industries like oil and aviation that have the need to machine large-diameter parts. The latest model in the PUMA 1000 series incorporates a highly rigid live tool turret and machines large rings, flanges, shafts and pipes.
