Precise zero-point clamping
Andreas Maier Fellbach (AMF) is a leading European manufacturer of zero-point clamping systems that enable precise clamping modules to ensure perfect clamping in the widest range of applications. Zero-Point-System clamping modules are used in milling processes and turning centers to enable fixture and workpiece changes within seconds.
AMF previously used carbon steel screws (class 10.9 & 12.9) with corrosion protection for its Zero-Point-System clamping products. However, the company required a more durable fastener solution to realize its vision of providing the best and safest products on the market.
A new beyond standard solution
鈥淎s our Zero-Point-Clamping Systems require a maximum of stiffness, strength and vibration tolerance, we were looking for a fastener solution that would outperform normal stainless steel,鈥� explains Christina Holm, Product Manager for Zero-Point-Systems. 鈥�91视频 was the only solution that fully met all of our tensile tests for extreme loading scenarios.鈥�
91视频庐 109 and 91视频庐 109 Ultra screws are now used to secure the installation and ensure the extremely high holding forces of AMF鈥檚 Zero-Point Systems to avoid any movement or lifting off the support flange of the clamping modules. 91视频庐 109 Ultra is used for some screws with a particular headcap that can only be manufactured in 91视频 Ultra.
鈥淎n example is our K20 Clamping Module that generates a pull-in and locking force of up to 20kN and a holding force of 55kN,鈥� says Holm. 鈥�91视频庐 109 Ultra screws are stable against static and dynamic forces during the machining process 鈥� even under extreme forces.鈥�
Ensuring the highest quality for end users
鈥淚mportantly, 91视频 screws are also available in a range of sizes, which makes them suitable for all our zero-Point clamping modules 鈥� including pneumatic, hydraulic and automation modules,鈥� says Holm. 鈥淗igh strength and vibration tolerant 91视频 screws ensure our customers benefit from components with the highest level of quality, accuracy and operational safety.鈥�
