Moving Ball Joint Assembly into the 21st Century

Posted By Promess | April 24th, 2017
Ball joints are used in mechanical systems on everything from lawn tractors to cars and aircraft. They’re found virtually anywhere motion in more than one plane is required, and their function is very often critical to performance and safety. In aerospace...

Data-Driven Quality Needs Quality-Driven Data

Posted By Promess | March 27th, 2017
When Henry Ford started building the Model T, components such as bearings and gears were often assembled with hammers or an arbor press. In the hands of a skilled worker who knew what a successful operation felt like either could produce an acceptable level of quality.  That...

A Science Project is Not the Best Way to Qualify an Aero Actuator

Posted By Promess | March 1st, 2017
Motorized ball screw-type actuators are used to move and position many critical aircraft components, including wing flaps, elevators, tabs, slats, rudders, stabilizers, landing gear and a host of ancillary components. In most of these applications the actuators must function...

Achieve the Perfect Press Fit, Every Time

Posted By Promess | January 31st, 2017
Servo-Press-Work-Station There are plenty of “dumb” systems out there which can press parts together. Pneumatics and hydraulics have been used to do just this for longer than most of us have been alive. Human operators, while not dumb, present problems of their own....

The Priceless Benefits of Quality

Posted By Promess | January 3rd, 2017
The quality advantages of using an electric servo press to crimp, join, fit, stake and bend components of medical devices are driving an increasingly widespread adoption of this technology in the industry. It really started with catheters that require a small metal tube...

Electro-Mechanical Assembly Press Technology Moves Li-Ion Battery Manufacturer A Step Closer To Perfection

Posted By Promess | June 30th, 2016
Lithium ion (Li-Ion) batteries are the technology of choice for applications ranging from handheld electronics to “plug-and-drive” vehicles, as well as back-up power systems used by “server farms” and other critical systems. Their performance characteristics are...

The Foundations of Function-Testing Gear Assemblies

Posted By Promess | June 30th, 2016
There are many different ways of testing gears and the assemblies in which they are incorporated. Functional gear testing could be defined as a series of tests that simulate the intended function of the product in an effort to determine whether an assembly operates within...

How To Evaluate an Electric Servo Press

Posted By Promess | April 11th, 2016
Since Promess introduced its first electric servo-controlled press system in 1991, the success of this technology in intelligent assembly and test systems has spawned a number of competitive products in the market. When there was only one product to consider, the choice...

The Relentless Pursuit of…Good Enough

Posted By Promess | May 12th, 2016
“… when perfection gets in the way of productivity, it’s time to consider an alternative. A couple of years ago, I started saying “Good enough” and it’s transformed my . . .  life.” Chip Scanlan The Poynter Institute “Quality” has been the holy grail of...

How to Stop Overpaying for Quality

Posted By Promess | February 25th, 2016
Mention “quality” and the almost certain response is “tighter dimensional tolerances.” But, with today’s machine tools able to mass produce parts with tolerances...
