The challenge of machining hip replacement implants out of cobalt chrome

It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”

The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.

A lot of attention is paid to the “business end” of CNC toolholders–the part that actually holds the tool.

“We are developing solutions for power workholding such as hydraulic swing clamps and block clamps, because the real estate on a fixture is so valuable,” says Jason Betz, product specialist for Carr Lane Roemheld (St. Louis). “This pushes the use of smaller workholding components as much as possible because the more parts on the fixture the greater the productivity.”

Sometimes succession of a family business from one generation to the next doesn’t always go as planned. Take, for example, Laser Specialists Inc. (Fraser, MI). Incorporated in 1986, the company was positioned at the forefront of laser cutting technology.

SAS Manufacturing LLC unveiled a new advanced machining facility for design, manufacturing, and assembly of aerospace components in Arvada, Colo.

As inventive and imaginative as 3D printer technology is, so are the materials that R&D labs have come up with to build parts, including conductive thermoplastics.

In an automobile engine, seven types of screws out of approximately 70 are considered critical to achieving the engine’s specified design performance, despite high vibration and heat. The seven include bolts for the cylinder head, crankshaft, con rod, flywheel, and main bearing cap, as well as for the camshaft cap, camshaft sprocket and VCT.

Additive manufacturers seeking to protect their products must secure every point in their manufacturing process, a need highlighted by the recent successful hack and sabotage of a drone produced by 3D printing, Richard Grylls, technical director at SLM Solutions, said.
