United Grinding North America will close its Fredericksburg, VA, office on July 1 and move those operations to its headquarters in Miamisburg, OH. “This tactical move is part of an overall strategy designed with the customer at the forefront,” said Theodore Neckel, director of corporate marketing for United Grinding North America.

Additive manufacturing is both growing and coping with growing pains. Companies “have to find ways to streamline” polishing and other finishing processes of 3D printed parts, industry consultant Terry Wohlers said today during a speech at RAPID + TCT.

Impossible Objects LLC, a Chicago-based company, has brought to market a new composites material manufacturing technology known as Composite-Based Additive Manufacturing (CBAM) 3D technology which produces Carbon Fiber Reinforced Plastic (CFRP) or Polymer Matrix Composite (PMC) parts.

Additive Manufacturing (AM) machines making metal parts have been out there for a dozen years. The machines have improved since the initial offerings and the number of companies that now produce them have increased exponentially. Many companies are now ready to invest in this maturing technology, and there are many more companies with machines that vary in technology and materials. Even the experts in AM are having difficulty keeping track of all of the new offerings.

Today, the productivity needed to be globally competitive requires ever increasing metal-removal rates during operations such as roughing and high-speed slotting. Process reliability is paramount, especially when working with difficult-to-machine materials.

Secure, accurate workholding sets the stage for consistent machining productivity. Depending on the parts and processes involved, workholding can be as simple and temporary as a plain vise or clamp or as complex and permanent as a machined and fabricated fixture that is custom-designed to hold a unique part.

When first introduced in the late 1970s, cutting tool coatings—especially titanium nitride (TiN)—were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.

Impossible Objects announced today the launch of Model One, its pilot 3D printing machine to revolutionize high-volume manufacturing and initial customer deployments with select Fortune 500 customers. The announcement took place at the RAPID+TCT 3D printing and additive manufacturing conference.

Toolholding for rotating round tools—end mills, drills, and taps—continues to evolve with innovative designs aimed at guaranteeing precision, security, and repeatability. As a result, suppliers of toolholding technology have made supporting the precision, security, and repeatability of shrink-fit, mechanical, and hydraulic toolholding the highest priority.
