What’s the Connection?

A lot of attention is paid to the “business end” of CNC toolholders–the part that actually holds the tool.

Maybe it’s Time to Try Some ‘Swiss Cheese’

These days the most important theme in superabrasive grinding wheel development isn’t the abrasive, it’s the bond. The diamond or CBN grains do the cutting, but the bond plays a decisive role in exposing the grains to the workpiece and enabling coolant to remove heat.

Hard Hips

The challenge of machining hip replacement implants out of cobalt chrome

Picking the Right Toolholder for the Toughest Jobs

When sizing up an application for a milling toolholder, it is necessary to consider the materials being machined, how aggressively metal is going to be removed, and any machining conditions that are likely to present a challenge to tooling security. By now, the pros and cons of hydraulic, mechanical, and heat-assisted shrink-fit systems are well known and results well documented.

Extrusion and Drawing Knowledge

Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.

Geometry Lesson Teaches Corvette How to Lighten Up

It’s been almost two decades since the C5 Corvette hit the streets with its groundbreaking chassis built around hydroformed steel bumper-to-bumper frame rails. The technology gave engineers a chance to create components that were both lighter and stiffer than traditional stamped and welded assemblies.

Turbos Turn Up the Heat with Challenging Materials

A new breed of turbochargers constructed of super tough alloys operates at higher temperatures and rotational speeds than ever before, resulting in greatly increased output in a smaller package for gas and diesel engines alike.

DIY: Creating Through-Tool Coolant Capability

New retrofit systems make it possible to quickly, easily and cost effectively transform the standard external-coolant live tooling heads on turning machine turrets into those with through-tool-coolant capability. And shops that have done the retrofit are experiencing longer tool life, more efficient chip control and less heat generation.

Lifting Devices Reduce Incubator Assembly Labor

Thermo Fisher Scientific, a leading manufacturer of laboratory technology, designed new incubators to cultivate human and animal cells. With 55,000 employees worldwide and group sales of $17 billion, Thermo Fisher Scientific is one of the world’s largest providers of laboratory and analysis technology. The company headquarters are located in Waltham, MA, near Boston.
