Toolholders & Workholding

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.

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.

Kurt's new KHU6 hydraulic unit comes ready with both single- and double-acting capabilities providing a convenient option to the users preferred clamping method. Single-acting method uses hydraulic clamping and spring return for unclamping. Double-acting capability uses both hydraulics to clamp and unclamp for faster, more precise setup.

Lexair's new Flex Grip closers are designed for versatility and efficiency, and they are proven to boost productivity for a variety of machining operations including 5-axis, rotary indexer and stationary applications. The manual/hydraulic closers are clamped through a screw pump with a spring return opening.

NT Tool's angle heads add a new cutting axis to existing machines, allowing you to machine from additional angles without the need for tilt tables. By building a new axis into the toolholder itself, machining plants can save greatly on setup costs and expensive investments in new machinery.

The compact, high-precision Quicktech S-32 ATM 9-axis, twin-spindle mill/turn center combines integral-motor main- and sub-spindles with a 190° B-axis milling head and a fast automatic toolchanger to maximize output of small, complex parts. Quicktech machines are distributed in North America exclusively by Absolute Machine Tools Inc.

EXSYS Tool Inc. has introduced a new space-saving 5-axis rotary table TAP for small, high-speed vertical machining centers. The table TAP allows users to upgrade a vertical machining center to significantly increase productivity without incurring the expense of a new machine, according to the company.

If you are looking for product quality improvements that only an ultraprecision tooling spindle can provide, and also require the robustness of an industrial grade design, Precitech says the ASD-H25 and ASD-Cx high-speed air-bearing ultraprecision tooling spindles by Levicron are precisely what you need.

Sandvik Coromant has unveiled a new range of CoroTurn Prime multitask and axial-type toolholders to help machine shops implement the new PrimeTurning methodology, which enables turning in all directions. The introductions allow users to maximize the benefits of PrimeTurning on multitask turn-mill centers and vertical turning lathes (VTLs).

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.

Using Finite Element Analysis (FEA), Kurt designed and optimized the new XL6 XtraLong vise to be better performing than its predecessor vise the 640XL. Boasting a 14.50" opening, the XL6 manual vise clamping capacity is .50" more than the 640XL vise and accomplishes the increase even while the over length was reduced by .42" to 24.10".
