Toolholders & Workholding

Even with minimal runout near the nose of the holder, conventional collet holders frequently see larger runout when measured at the cutting edge of longer tools. NT Tool's original "R" Zero system eliminates this problem by utilizing a four-point adjustment mechanism to adjust runout at the tool tip to as low as 0µm to 2µm.

ITI Tooling Co. Inc.'s portfolio of more than 20,000 different toolholders includes VDI toolholders with shaft diameters of 16mm through 80mm and BMT block toolholders (BMT55 to BMT85) to machine-specific holders for machine tool builders such as KIA (WIA), Mazak, Doosan, DMG Mori, Nakamura, EMCO Maier, Hurco, YCM, Samsung, Hwacheon and Okuma.

The mid-size diameter and adaptability to custom fixture designs make the Unilock 138 series BIG Kaiser's best-selling round chuck workholding solution. Now come two new additions to the 138 series that make it an even more powerful and versatile solution for demanding workholding scenarios—the ESM 138 Turbo and the ERGO 138.

J.W. Winco Inc. offers GN 927.7 stainless steel clamping levers with eccentrical cam with stainless steel contact plate, tapped type, in inch and metric sizes.

Master Bond EP21NDCL is a unique two component epoxy system that cures optically clear in thin sections, even though Part A is translucent and Part B is light amber.

NT Tool offers its R-Zero runout adjustment system in its CTZ toolholders for large cutting tool diameters.

Developed with optimal performance and value in mind, the new Universal Drill from Niagara Cutter is a solid-carbide drill that combines a special multi-purpose geometry with advanced coating technology to reportedly provide reliable, predictable tool life and a low cost per hole, especially in high-volume production environments.

Huot says its new Angled Platform makes an excellent addition to a machine cell and will provide value for decades.

The Eldorado M75-30T from Kays Engineering Inc. is a twin-spindle gundrilling machine widely used for the manufacture of orthopedic implants, including femur nails and bone screws.

Lexair's new Model 16C wrench-operated collet chuck has an integral A2-5 nose to accommodate standard 16C collets up to 1.625", as well as bolt-on closing rings and ID mandrels.

Mass production components always present challenges: planning the machine installation site, linking machines and coordinating cycle times all to achieve the perfect combination of quality and cost efficiency. The larger the workpiece the more demanding the planning process for the manufacturing set-up. However, optimizing the production of such parts, for example by reducing expensive automation components or reducing the process chain to just a few machines, can drastically cut costs. EMAG's VLC 800 vertical turning center for chucked parts up to 800mm is a production system that combines all these benefits in a single machine thanks to its integrated automation systems.
