Courtesy: FestoThe parallel, three-point, radial and angle standard grippers, DHxS, from Festo are compact and offer reliability in the gripping process. Standard grippers are the first choice for cost-effective, lightweight and compact construction of handling and assembly systems. The parallel, three-point, radial and angle gripper series DHxS from Festo features optimized gripping force retention and overload protection as well as integrated sensor slots. It offers increased reliability in a range of sizes and stroke lengths.

A number of features ensure reliability and precision. The integrated fixed restrictor provides an effective safety buffer, protecting against overloading during high-speed gripper motions and preventing damage due to excessive forces. The integrated sensor slots in the medium and large sizes offer the advantage of cost-effective stroke sensing via sensors SMx. Their successful integration has resulted in a slim, compact design without any interference contours caused by external sensors. The new, compression spring-assisted gripping force retention provides more security in the event of a pressure failure. In addition, T-slot guides increase the torque resistance of the gripper jaws.

The double-acting piston drive gives the standard grippers stable kinematics and maximum repetition accuracy. A wide range of mounting options in the form of threaded, fitting and centering holes make the new generation of Festo standard grippers very flexible to mount. 

The parallel and three-point grippers DHxS have a lightweight aluminum housing with integrated receiving hole for the pneumatic piston. The force generated by the linear motion is transferred to the low-backlash gripper jaws by means of lever kinematics. Since the lever is indirectly in mesh with the two gripper jaws via a piston rod, there is no need for additional synchronization.

The pneumatic pistons of the double-acting DHxS radial and angle grippers act on the gripper jaws, mounted on pivots in a gripper jaw guide, by means of a slotted guide system. As with parallel and three-point grippers, this means that there is no need for separate synchronization.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
