Toolholders & Workholding

A titanium nitride (TiN) bearing nut improves rigidity as the uniquely designed gold ring reduces collet damage, reduces micro vibration with the collet flange, and eliminates friction with the collet. It improves the cutting rigidity and the quality of the cut compared to traditional collet chucks.

Full grip jaws are manufactured for chuck sizes ranges between 4" and 10" diameters and are available in 1018 steel and 6061 aluminum. Jaw heights are available between 1" and 4". Soft jaws are available in 1018 steel and 6061 aluminum, in heights from .75" to 5.00 inches, and widths from .75 to 3.00 inches.

LANG Technovation General Manager Jon Dobosenski discussed several new products introduced at EMO Hannover 2023, including the company's new workholding rail system, a new mini vise with a two-stud pattern, and a new FS series of vises with serrated jaws.

Michael Herman, vice president sales for BIG DAISHOWA Inc., discussed a special promotion for the company's fine boring kit, which features the EWN2-152 fine boring head from BIG KAISER is said to enable manufacturing precise bores with guaranteed precision of .00005".

Shop seeks to eliminate repeated replacement of loose retention knobs.

The recently launched tools, toolholders and chipbreakers move manufacturers toward better results easier, more quickly and with cost savings. "We're focused on developing new ways for our customers to solve age old problems while taking full advantage of their machine tools," said Mia Bökmark, Vice President Product Offer & Innovation at Seco.

The holders accept CCGT3xx, DCGT3xx and VCGT2xx indexable inserts and provide a high level of indexing accuracy even when turning parts with tight tolerance specifications. The short head dimension enables short clamping and high stability. The shank dimensions are 12 mm × 12 mm and 16 mm × 16 mm.

Pneumatic Shaft-Locking Clamps are designed for quick change applications. In the pneumatic version, when connected to air, the clamp allows clamping/unclamping in one operation. They are perfect for secure clamping of sliding shafts and for use on machines where many clamping or unclamping cycles are run, or for multi-clamping applications.

The #9629109 Heavy-Duty C-Clamp with a copper spindle from Palmgren has a throat depth of 3-7/8 inches, a spindle diameter of 15/16 inches, clamp pressure of 6900 lbs. and weighs 8.7 lbs.

The DCN drills feature cylindrical shanks, which enable clamping of the drill in hydraulic toolholders (most recommended) or in spring collets. All drill bodies feature helical coolant holes. Prior to using the 12xD drill, it is recommended to drill a pre-hole by using a DCN 1.5xD drill or a centering drill.

Unique to Nikken rotary tables is the innovative and patented carbide worm system comprised of a carbide worm screw, ion nitrided worm wheel (HV930), and hardened steel bearing surface (HRC58-60). The V grade solid carbide worm screw helps to ensure high rigidity and virtually eliminates wear.

The TechniDrill 2.00-30-48 has a gundrilling diameter capacity of 2.0 inches (50.8 mm) and a maximum gundrilling depth of 48 inches (1219 mm). It features a 30 horsepower AC spindle motor and two-speed gearbox to provide versatile gundrilling performance.
