Mapal Boring Bars

To make the fine machining of the crankshaft bearing journals on a machining centre economical, line boring bars are often used. With an innovative concept, MAPAL has been able, in collaboration with a machine manufacturer, to optimize this processing in several ways: Compared with conventional line boring bars, quality can be increased, processing can be sped up, and tool service life can be increased, all thanks to the new line boring bars with compensation-enabled cutting edges.

Nothin’s going to touch you …

... in these golden years," crooned the late David Bowie in one of his smash hits. The term "golden years" is also used in Albert B. Albrecht's book "The American Machine Tool Industry: Its History, Growth, Restructuring & Recovery," which he revised in 2015 for the third edition. AMT—The Association For Manufacturing Technology sponsored the book. Albrecht defines the golden years of the machine tool industry as being from 1948 to 1998. "It was during this period that the United States machine tool industry led the world in both machine tool production and consumption," Albrecht wrote.
