Zero point clamping technology for enormous setup time reduction
Zero point clamping technology
Simple, fast, and secure setup of workpieces or clamping devices on 3-axis, 4-axis, or 5-axis machines and fixtures, clamping tombstones, or pyramids. The gredoc interface between the machine table and the clamping device results in a significant reduction in setup time. Discover GRESSEL’s zero-point clamping systems – learn more now!
How does the gredoc mechanical zero point clamping system work?
The locating pin is pressed by the clamping bolt into the precisely fitting half shell (polygon). The locating pin is thus positioned accurately in the X / Y direction. At the same time, the locating pin is pulled downwards by the retraction slope with 20 kN.
What are the advantages of a zero point clamping system?
Setup and idle times can be significantly reduced, thereby increasing the machine’s spindle runtime.
What pull-in force does gredoc achieve?
20 kN pulling force with 30 Nm torque.
What repeatability is achieved when changing with gredoc?
Highest repeatability < 0.01 mm.
How many types of clamping bolts are there?
The gredoc mechanical zero-point clamping system uses only one type and size of clamping bolt.
