Dillon Manufacturing's hard and soft jaws, pie jaws, collets and more are available for a wide variety of workholding applications. Their same-day shipments keep job shops running without tying up capital in inventory or worrying about lead-times.

Tungaloy introduces a new line of collet chuck sleeves for the TinyMini-Turn miniature boring tool system, enabling a quick changeover of its solid-carbide boring bars.

REGO-FIX offers a new cryogenic coolant technology based on the powRgrip system. Called CRYO-powRgrip (PG-CRYO), the system is produced in conjunction with a European supplier of carbon dioxide coolant and targets customer needs to boost productivity and eliminate secondary cleaning operations, especially for medical industry part-production operations.

As a recent addition to its EPPINGER PRECI-FLEX modular tooling system, EXSYS Tool Inc. offers a two-collet chuck that doubles the machining capability of one turning machine tool turret station.

Weiler Abrasives has introduced its new line of CrossFlex honing brushes designed to provide machinists with performance and value for their professional honing applications. Available in small, medium and large diameters and with heavy-duty options, these brushes impart a surface finish free of metal burrs and are suitable for manual or automated use.

Kitagawa NorthTech Inc. introduces its new DKF Series of low-profile collet chucks. The DKF low-profile collet chuck features a compact nose, which is required when additional tool clearance is needed in tight workpiece and machining environments.

PFERD has introduced a new series of 100 percent stainless steel power brushes designated INOX-TOTAL. These new brushes provide optimal protection against corrosion, as all components of the brush are produced from 302 stainless steel (INOX), making them ideal for use in environments highly sensitive to contamination such as nuclear power and pharmaceutical industries.

Special top jaws from Dillon Manufacturing can be manufactured to grip a components ID, OD or a combination of both, to suit any workholding application.

Shops that seek to maximize milling performance while they reduce tooling inventories will benefit from newly introduced Power Milling Chucks from Seco Tools. With holding power and transmittable torque that rival hydraulic and shrink-fit holders, Power Milling Chucks deliver high precision with 5-micron runout accuracy at 3 times diameter in addition to enhanced application flexibility and cost effectiveness.

Dillon Manufacturing specializes in premium chuck jaw products for large-diameter (15-60 inch) chucks. Matching specialized workholding to the large diameter chuck allows faster, easier and more profitable setups. Available in standard configurations to fit virtually any chuck manufacturer, many sizes of hard or soft top jaws, or full grip (pie) jaws are available from stock or with industry-leading lead times.

What is the main purpose for coolant application? Of course, among many reasons, primarily it's for the lubrication and cooling of the cutting edge and, in addition, to help facilitate chip evacuation. REGO-FIX has launched a cost-effective and efficient attachment for the application of coolant-lubrication liquids through the tool, based on an ER collet nut, which is suitable for use on SUHNER feed drilling units.
