When Cold Forming Threads Makes Sense
Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
Read MoreDual-Carbide Technology Addresses Basic Drilling Challenge
A dual-carbide-grade drill has a micro-grain carbide core blended to provide toughness to prevent chipping at the drill's point. Surrounding the core is a second carbide grade that provides hardness needed for wear resistance at the drill's outer edges.
Read MoreLose The Peaks, Leave The Valleys
Plateau honing improves cylinder wall surface finish by gently removing tiny peaks of torn or folded material. Ball-style honing tools are commonly used to produce this desirable finish.

Suggestions help me do my job. Suggestions from my colleagues help me see faults in my articles that I am overlooking.
Read MoreMachine Tools Used As Dedicated Equipment…For A Little While
Two keys to this shop’s success are versatility and speed. It uses flexible machining centers, rather than dedicated equipment, and constantly reconfigures them into new cells for new jobs. The speed at which it can do this, in addition to in-house tombstone manufacturing capability, provides the nimbleness to quickly respond to its customers’ needs.

When Four Spindles Make Sense
For the right applications, four-spindle CNC chuckers offer practically zero delay for part loading. That’s because two spindles can be loaded while the other two are making chips.
Read MoreBecoming More Than The Mom & Pop Race Shop
Carney Custom Machining started with a VMC and customer base largely comprised of drag racers. Now the shop is vying to win work from other sources, and CNC turning is a big part of that strategy.
Read MoreMicro "Turning" Using Wire EDM
A high speed rotary spindle allows a wire EDM unit to turn round parts with diameters as small as 0.002 inches to a finish of 0.2 Ra while maintaining accurate concentricity.
Read MoreBe Prepared
The timing was eerie. In July 2005, I completed a story that encouraged shops to develop a disaster recovery plan so they’d be prepared in the case a catastrophic event befalls them.
Read MoreThe Value In Providing A Little More
The shops I choose to profile in this magazine are those that apply innovative metalworking technologies in creative ways. Many of these successful shops share another trait: they offer customers more than they might expect of their vendor.
Read MoreIndexable-Insert Broaching Tool Technology For Lathes
A new indexable-insert-style broaching tool for CNC lathes provides two cutting edges per carbide insert. Because the tool body can remain installed in the lathe's turret during insert indexing or replacement, it is unnecessary to re-zero the tool after the change.

I’ve visited shops that I thought were as clean as they realistically could be. Others, well not so much.
