Special shaft collars and couplings that can be machined from wide range of materials to meet strict OEM design requirements are being introduced by Stafford Manufacturing Corp.

WDS offers stainless steel versions of many of the components that it supplies to machine and equipment builders across the UK and around the world. Wherever possible it offers stainless steel versions of its most popular components.

Souderton, PA – Solar Atmospheres recently awarded the title of CEO Emeritus to Roger A. Jones, FASM.

As a market-leading photo chemical etching specialist for over 50 years, Precision Micro has developed etchant chemistries and processes that make etching possible on a wide range of metals. Stainless steel, however, remains the number one choice for many of the company's customers due to its versatility, the numerous grades available, and the vast array of finishes. Precision Micro etches more than two million steel and stainless steel components each month, making it the largest sheet etching company in Europe.

Custom composite clad metal wire that can combine the properties of several materials where solid wire is limited or too expensive is available from Anomet Products. In addition to serving OEMs, the firm is seeking wire suppliers who want to expand their product offerings.nnn

It becomes increasingly important as the table travel is increased. Ambient temperature changes are one obvious source of thermal expansion. As the positioning table warms, its constituent parts undergo expansion, at a specific rate for any material. Accordingly, to permit any two users to agree on what constitutes an "accurate" positioning system, all critical dimensional measurements world-wide are understood to take place at 20 degrees C (68 degrees F).

Chip Bobbert eyes a sheet of shiny aluminum that is several feet long and crimped on one end. He guesses that this was once the backsplash of a restaurant kitchen. Nearby, he spots another piece of metal with a square opening at the center. When he mentions that it likely once framed the entry to a roof or ventilation shaft, the shape of the piece makes sense. He then picks up a softball-size chunk of dense stainless steel. With an intricate series of holes shooting through the thickest part, it looks like a central piece of a complex engine. "Some of this stuff is crazy," Bobbert said, pointing out the holes. "If you look at the precision machining, somebody paid thousands of dollars for that."

It is October 1978. On Oct. 13, my discovery at the former Matra company in Frankfurt that PCD can be eroded by means of electric sparks was registered at the patents office. In October 2018, we looked back at 40 years of experience in the application of spark erosion for manufacturing and versatile application with polycrystalline blades of PCD- and PCBN-tipped tools.

Between 1974 and 1976, polycrystalline cutting materials, such as PCD and PCBN, could show their potential for the first time. As a result of the hardness of diamond, combined with the sharpness for machining tasks, the superiority of PCD was displayed early on when turning, milling and drilling.
