Burrs, sharp edges, and rough surfaces plague even the most precise metal-cutting or forming process. Deburring and finishing can often be treated as the step-child of a manufacturing process, but its importance is growing as tolerances get tighter and precision devices become the norm.
VMCs have had a productive past, present and the future looks promising
The use of electrical discharge machining, or EDM, is spreading as manufacturers need more precisely cut workpieces, often made from tough to machine materials.
Dau Thermal Solutions Inc. (Macedon, NY) was finding that its spindle speeder was definitely not up to speed when it came up against the test results for NSK’s HES510 series electric spindle.
In auto racing, small details have a major impact on success—a concept very familiar to performance racing parts provider Oliver Racing Parts (Charlevoix, MI). Oliver produces performance connecting rods for the world’s leading engine builders.
Methods Machine Tools Inc. (Sudbury, MA), a leading supplier of precision machine tools, 3D printing technology and automation, recently introduced an automation cell designed to greatly boost 3D manufacturing throughput.
Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
Why use a metrology device on or near a machine tool? It isn’t just useful for making sure a tool is present or monitoring tools for wear or breakage. On-machine measurement technologies can save time and money, by speeding up processes and eliminating extra personnel, and they are a critical step in the movement towards “lights-out” manufacturing.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.
