Machie tools designed for submicron accuracy and subminiature workpieces are following design strategies that depart from conventional practice. The Hyper2J from Makino is described as a case in point.
Any manager of a job shop knows that it would be a big mistake to take on work that the shop doesn’t have the time or resources to handle. The overload would surely cause at least one missed delivery, and maybe more.
In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.
Wire EDM (electrical discharge machining) has been configured with the wire in a vertical orientation for decades, so the appearance of a wire machine that orients the wire horizontally is truly a novel development.
New regulations regarding overtime pay went into effect in August, amid much controversy and debate. Affecting mostly white-collar employees, these regulations were promoted as an attempt by the Department of Labor (DoL) to make the rules clearer, simpler, easier to enforce and more reflective of today's job duties, pay rates and work environment.
Designing hole-making tools is a game of compromises, says Goran Melin, drilling product manager at Seco Carboloy. 'Where you gain in one area, you must pay somewhere else,' he says. The trade-offs usually include tool life, accuracy and stability. Tool designers are constantly juggling these variables to find the best solution.
We can make it. The phrase has several meanings, and all of them apply to the manufacturing industry as we approach IMTS, the International Manufacturing Technology Show.
By now, many of this year’s graduates will be joining the workforce or continuing their search for jobs. In my readings and discussions lately, I’ve run across some insightful observations about the U.
