Has Lean Become Too Extreme?

Surges in demand reveal a weakness of just-in-time supply chains.


Another Angle On HSM

The savings in setup time were welcome enough, but this mold maker found that a 3+2 machining center also accelerated its use of high speed machining.


Attaining Ten-Millionths Bore Accuracy

Conventional honing has been continuously improved and automated, now allowing boring accuracies to be measured in millionths.


The Value Of Indexable-Insert Center Drills

This indexable-insert center drill, said to be an industry first, combines the drilling performance advantages of solid carbide with the positioning repeatability and quick-change benefits common to indexable-insert tooling.


Triple Tap Life

A maker of vehicle components finds that a treatment process for taps produces dramatically longer tool life.


Cutting Spiral Bevel Gears On A Five-Axis Machining Center

To produce high-precision ring gears in low- to mid-volumes, an emerging option is the use of five-axis machining centers. Mitsui Seiki CNC vertical and horizontal machining centers are being used in this application.


3D Scanning: Reproducing One-Of-A-Kind Prototypes

A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center. 


A New Spin On Vertical Grinding

Simultaneous, dual-wheel vertical grinding offers advantages for finishing bearing surfaces and other critical features on shafts. Having two opposing grinding wheels in contact with the workpiece at the same time neutralizes axial forces and shorte...


New Honing Options For Hypereutectic Aluminum Cylinder Bores

Hypereutectic aluminum is saturated with silicon particles that must be exposed during honing. A two-stage process first hones a cylinder’s wall to a mirror-like finish and then relieves aluminum around the silicon particles.


How to Hone an Atypical Aluminum Alloy

Hypereutectic aluminum used for engine blocks contains silicon particles that must be exposed during cylinder honing. This can be done using a cushioning, elastomer honing tool that allows individual abrasive particles to “bounce” over the silicon p...
