Toolholders & Workholding

The smallest clamping range yet from BIG Daishowa is the Super Slim 3S hydraulic chuck is intended for extremely repeatable high-precision microdrilling and microendmilling in the most challenging work envelopes thanks to its slim nose and tapered body.

MAPAL has expanded its program of narrow-contour HTC (High-Torque Chuck) clamping chucks, whose narrow shapes are produced without a restrictive brazed joint thanks to additive manufacturing. These new chucks can directly clamp diameters of 3, 4 and 5 mm, also allowing hydraulic clamping chucks to be used on the microscale, for example in medical technology or the timepiece and jewelry industry.

Soft jaw blanks from Dillon Jaws feature a milled surface on the jaw end, opposite to the clamping surface, which serves as an easy-locating feature. This datum serves as a location point for positioning the counter-bored holes and the jaws' serrations resulting in exact dimensional matching of Dillon jaw sets.

Hassay Savage Co. has introduced a new, precision index punch broach holder series for Swiss-style machining centers. Precision made of 17-4 stainless, this holder will provide strength, rigidity and accuracy for all punch and index broaches with a shank size of 8mm, according to the company.

ReamTec easyZERO runout compensation nuts quickly correct runout errors and misalignment for all round tools using ER collets. Easy-to-use, innovative replacement nuts feature six adjustment screws that allow for up to 0.011" runout to be dialed in easily, allowing for more accurate machining, tighter tolerances and better surface finishes—especially on difficult parts.

BIG KAISER introduces the Mega Perfect Grip from BIG Daishowa, a simple to handle, heavy-duty milling chuck for heat-resistant superalloys (HRSA) that eliminates endmill pullout under heavy torque loads. For manufacturers using milling chucks, pullout is a major issue, particularly when machining HRSAs, such as titanium or Inconel.

Emuge Corp., in partnership with Albrecht Precision Chucks, has introduced Emuge FPC mill/drill chucks that reportedly provide unprecedented rigidity, vibration damping, concentricity, machining speed and tool life versus conventional chuck technologies for milling and drilling applications.

Exsys Tool Inc., which is the exclusive supplier of pL LEHMANN rotary tables for North America, recently announced the expansion of its ultra-high precision products to include the pL LEHMANN swissClamp modular clamping system, according to the San Antonio, Fla.-based company. The modular clamping system reportedly allows operators to mount multiple workpieces on machine tool tables for uninterrupted production and unmanned operations.

Heimatec announces immediate availability of BMT (Base Mount Tooling) standard products. In addition to standard X- and Z-axis tools, styles such as adjustable tools, speed increasers and internal coolant tools with capabilities to 140 bar (2,000 psi) are available in an assortment of standard BMT tooling types, including BMT 45, 55, 65 and 75.

Briney Tooling Systems worked closely with a manufacturer to develop a special dual-contact, CAT 50, stick turning toolholder for an Okuma MacTurn 550 mill/turn center. The customer had some special turning stick tools that were 1.5-inches square and there was no standard for the lathe stick tools.

Seco has added a new range of taper-face toolholders to meet machinists' increasing needs for higher production and process reliability. These new options provide two surfaces of contact to offer increased rigidity and consistency compared with standard holders when machining complex parts at high cutting parameters.

NT Tool's Hyper Spindles use a 1:5 ratio internal gear system to multiply the RPM of existing machines up to 5 times at the cutting edge, with a maximum of 30,000 min-1, according to a recent announcement from the Franklin, Tenn., company.
