Flexibly gripping in a machine tool

The SCHUNK unit can be used together with centric or parallel grippers.

03-11-2014 - With the Lean Automation Program from SCHUNK, the competence leader in clamping technology and gripping systems, machine tools can be automated quickly, easily, and cost-effectively. The principle is simple: via a shank interface, handling and cleaning modules are clamped in toolholders, deposited in a tool rack, and on request they are exchanged in the machine spindle.


In order to prevent the force build-up on the machine spindle from becoming too high when the machine tool is self-loading, SCHUNK has developed the GSW-B-AGE compensation unit. It compensates tolerances, inaccuracies in all six degrees of freedom, and simplifies automated joining processes, where the workpieces are to be fixed over bolts or pins. Moreover, the workpieces are pressed with a compensation unit against the fixed jaw of a clamping force block, until the clamping process is finished. The compensation unit is equipped with an interface to the gripper on one side, and on the other with a 20-mm shank, which can be clamped in many conventional toolholders. The SCHUNK unit can be used together with centric or parallel grippers.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
