Tooling & Workholding

Mills, drills, taps, reamers, boring bars, cutters, inserts, dies, punches, abrasive wheels and other devices used to cut, mill, drill, grind, tap, notch, punch and form material. Chucks, fixtures, clamps, blocks, angle plates, tooling columns, dies and other mechanisms used to position, locate and hold material as it is being cut, milled, drilled, ground, tapped, notched, punched, formed or welded.

Beat the Competition on a Budget with this Entry-Level ‘Automation’

The way we machine parts has changed significantly over the years. Now it’s time to change how we think about workholding too.

Chucks

How Shrink Fit Chucks Fit Single Blade Applications

See why Starrag uses shrink fit chucks so their rotationally symmetric clamping body has less interfering contours and higher run-out accuracy when roughing and finishing hard-to-cut materials used for highly precise turbine blades, impellers, blisks and other structurally complex parts.

Is BIG-PLUS An International Standard?

Buyer Beware: This system has not been standardized by any governing body. If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original for half the price, you risk unsatisfactory performance and/or damage to very expensive spindles. Here’s why.
Cutting Tools

Efficiency Reigns Supreme

In the aircraft manufacturing supply chain, one thing is certain: process improvements – both large and small – can have a massive impact on the bottom line.
Drilling Tools

How to 3D Print Precision Drills

The days when precision tools and additive manufacturing strategies could not co-exist are history.
Fixturing Systems

Using Adaptive Grippers as Flexible Fixturing For Robotic Welding

Using a traditional jig for every type of piece and assembly is complicated and expensive when welding small volumes or high mixes of parts. Why not use a robot with an adaptive gripper to feed a welding robot? This could replace most of the templates currently used by adapting to any part size and shape and holding them firmly while welding.
Grinding Wheels

Grinding Gamma Titanium Aluminide

New grinding technology is being researched on this intermetallic to help lower the costs of manufacturing aerospace engine components, develop grinding expertise, and design custom-bonded abrasive and superabrasive grinding solutions that are ideal for efficient and damage-free grinding of components made of titanium aluminides.

Benchmark Survey of Industrial Metal-Cutting Organizations

Amid a challenging operating environ­ment, the LENOX Institute of Technology conducted a survey of 100+ industrial metal cutting operations that identified three key areas where organizations can gain additional productivity and efficiency on the shop floor. 
Threading Tools

Thread Form Now Available for High Speed CNC Machining

Stanley's Spiralock thread form has been used in applications for NASA’S Space Shuttle, the Saturn Cassini orbiter, and more.
Vises and Vise Jaws

Reinventing the Unbreakable Grip

Examine the design of these machine tool vise jaws to understand how they enable aggressive 5-axis machining of high-value medical and aerospace parts in a single setup by clamping on as little as 2 mm of surface.

Welding & Fabrication Catalog

The 52-page Welding & Fabrication Catalog from Weiler is available in print and digital versions and contains product information for the new Tiger X flap disc and a full line of welding and fabrication solutions, including coated abrasives, bonded abrasives and brushes.
Weiler's new catalog is available in both print and online versions and features the new Tiger X flap disc.

Innovations in Workholding

Ideal for machines with short stroke cylinders, the ROTA NCX from SCHUNK is a power lathe chuck with a quick jaw change system that can decrease set up time up to 80 percent and be changed out with a repeat accuracy of 0.02 mm. It boasts a large through-hole and easily replaces conventional lathe chucks. 
Workholding must be updated to make full use of the small lot flexibility that machine tools now offer so that the same part cost can be achieved in much shorter production runs. Here are some of the latest advances in workholding technology for shops to consider. 

Versatile Workholding Workhorses

The Stallion Hybrid from TrunnionTable.com eliminates need to remove the trunnion table, reduces setups and increases productivity by allowing three-jaw and four-jaw chucks, collet chucks and faceplates to install quickly, without removing the table, for a low-cost productivity booster on machine tools. One shop went from 11 setups on five machines down to six setups on one machine by adding the hybrid trunnion.
Versatile Stallion Hybrid trunnions from TrunnionTable.com accommodate a variety of vises, fixtures, 3-jaw and 4-jaw chucks and collet chucks for flexible job shop workholding.
