Beginning around six years ago, one machine tool builder after another added laser cutting and even welding to their products’ already impressive repertoires.
“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.”
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.
Hainbuch America Corp., Germantown, Wis., offers a modular workholding system with maximum flexibility and designed for a wide range of part diameters, configurations and small quantities.
Balanced toolholding assemblies, with even weight distribution, operate better. Unbalanced assemblies may experience vibration and shorter tool life, which are amplified by high machining speeds.
Fiber laser welding continues to grow as it improves in weld quality, reliability and performance. Many fiber laser welding applications are autogenous, where the weld is formed entirely by melting parts of the base metal and no additional filler wire or powder is used
