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.

Common CNC Grinding Mistakes

Proper grinding process parameters can eliminate a lot of the “black art” of CNC grinding. One critical variable is the grinding wheel being used and the dressing of the grinding wheel.

Chucks

Hard Turning on a Magnetic Chuck

Figure 1. All three areas of the hardened ring on this magnetic workholding set-up will withstand a 0.200 in depth of cut at 0.020 in feed per revolution. A demagnetizing cycle provides easy workpiece removal.
Green or hard turning on a magnet is becoming more accepted as an alternative for lathe chucking, particularly for rings which are vulnerable to deflection.
Collets

Shaving More Seconds Off Quick Changeover

Using the BENZ Solidfix system, operators no longer have to remove the main tooling unit itself. Instead, they only change the adapter that holds the pre-measured tool. Setups can be changed in less than 15 seconds without using any special tools. The shop also doesn’t have to carry as many expensive live tools because all they need are the quick change adapters.
Take a look at how this job shop uses a highly versatile modular quick change collet system to perform setups and changeovers in speeds of 15 seconds or less.

Cutting Tools and Science Fiction

Adveon software helps streamline and optimize cutting tool planning and preparation for shops now, but looking ahead, it will be a vital part of the comprehensive smart manufacturing systems that integrate manufacturing intelligence across the entire production operation. (Photo courtesy of Sandvik Coromant)
We are quickly moving from information technology to intelligent technology, toward a time when a worn cutting tool insert will know when it’s time to be replaced by a fresh one and will ask an available robot to get a new one and make the change.
Drilling Tools

How to Thread Nickel-Based Alloys

This pipe tap uses Variable Helix Correction (VHC) technology that provides a specially ground relief geometry in the primary cutting zone, generating a smaller and tightly rolled chip formation.
Proper tooling selection is the key for optimal results in this demanding application.
Fixturing Systems

Using Adaptive Grippers as Flexible Fixturing For Robotic Welding

The goal was to use a 3-Finger Adaptive Gripper as flexible fixturing instead of traditional jigs inside a complete robotic welding cell. Several tests were conducted to position a piece on a structure at ± 1 mm accuracy and weld it. Each step had to be reproduced numerous times with the same accuracy.
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.

Best Practices for Surface Preparation and Cleaning in Pipeline Applications

For most surface conditioning and cleaning jobs in pipeline welding applications, there are four common tools that are most often used: stringer bead brushes, aluminum-backed flap discs, bonded abrasive wheels and grinding wheels. 
Surface preparation and cleaning is just one part of the large process of oil and gas pipeline welding, but it’s a step that can have a significant impact on the productivity, quality and efficiency of the job. Proper preparation and cleaning in pipeline welding applications can help extend tool life, benefit operator safety and improve productivity and efficiency.
Punches and Dies

Clever Turret Press Tooling Produces More Parts In Less Time

In the turret, Marathon Plus tooling nibbles parts at up to 600 hpm and punches at up to 220 hpm. Full length guiding provides perfect tool alignment and stability at these top speeds. The tooling is an ideal match for Murata Weidemann's servo motor run drive design, resulting in higher productivity.
Tooling changeover is a priority for this sheet metal job shop, which achieves quick setups, extra durability and increased uptime by using advanced tooling  that makes its turret presses "operate like new."
Saw Blades

Benchmark Survey of Industrial Metal-Cutting Organizations

Despite a trend toward internal process improvements, machine downtime, blade failure and opera¬tor error remain the top-three sources of frustration for industrial metal cutting operations on the shop floor.
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

The Spiralock T-10 straight flute tap has a specialized geometry for short-chipping materials such as cast iron and hardened alloy steels.
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

SinterGrip jaws use scientifically designed, serrated, carbide inserts to penetrate the workpiece edge to a minimal, controlled depth and exert a push-down force on the part. Thin parts can be machined without deformation by clamping them at 6,600 lb force to achieve penetration, then lowering the force to 2,200 lb with no loss of gripping power.
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.

Grind It Out

The XCAVATOR ultra high removal grinding wheel from Walter Surface Technologies is ideal for the toughest, most demanding grinding jobs in metal fabrication, steel mills, mining, oil and gas, and shipbuilding.
Grinding represents a major part of shop costs. Take a look at the latest generation of flap discs, wheels, brushes and other tools that can help save time, reduce costs and improve the efficiency of your metal finishing operations.

Put On Hold

For precise serial production, the ROTA NCO lathe chuck from SCHUNK has the highest clamping force, lowest jaw stroke and lowest height of any chuck in its class, ensuring more space in the engine room, shorter cycle times, and higher versatility.
The increase in higher precision machining is creating demand for stronger, more durable, faster acting, closer tolerance chucks and collets that can grip and hold the parts and the tools being used. Here is a review of some of the latest chuck and collet solutions that meet that demand.

Drilling, Tapping and Threading Holes

Designed for use with hand-held drills, 1-Series and 2-Series Tungsten Carbide-Tipped (TCT) Hole Saws from CS Unitec cut clean, fast holes without grinding the core. The TCT cutting edges last longer than bi-metal edges and can be run at higher speeds and feeds to create holes of exceptional quality and accuracy.
Take a look at some of the newest equipment and tooling that are helping shops make their holemaking operations more productive and profitable.
