Schunk's Vero-S NSE Mikro 49-13 Clamps Small Parts
Schunk’s Vero-S NSE Mikro 49-13 is a completely sealed miniature clamping module specifically for metalcutting, assembly, handling and measurement applications.
Schunk’s Vero-S NSE Mikro 49-13 is a completely sealed miniature clamping module designed for metalcutting, assembly, material handling and measurement applications. The module measures 49 mm in diameter, with a height above table of 13 mm.
The clamping module is actuated with an axial piston, which is said to result in high pull-down forces despite the compact dimensions. The dual-stroke drive system achieves pull-down forces ranging to 1,500 N by using the integrated standard turbo function. Depending on the thread size of the 10-mm diameter clamping pin, holding forces range from 3,000 N (M3) to 5,000 N (M4). Self-retaining, form-fitting locking is performed mechanically via spring assembly.
The position of the clamping slide is detected through dynamic pressure monitoring, making the module suitable for metalcutting and automation applications. A 6-bar pressure system is sufficient for the module’s pneumatic function. All functional parts are made of stainless steel.
Finding a way to fixture contoured marine propellors proved to be this shop’s biggest challenge in developing an effective automated machining cell.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
Modular fixturing makes sense for this manufacturer, whether it's machining one- or two-of-a-kind parts for its custom machine tools or larger quantities for its contract machining business.
