Automatic Positioning System Reduces Setup Times
IMTS 2018: SMW Autoblok’s APS zero-point clamping system connects the machine tool, the clamping device and the workpiece.
SMW Autoblok’s APS zero-point clamping system connects the machine tool, the clamping device and the workpiece. The system can be used in turning, milling, measuring or grinding operations. Emphasizing flexibility and speed, the system is said to reduce setup times by as much as 90 percent.
The system locks into the proper position by lining up a series of pins on the workpiece or workholding with bases mounted on the machine. When the pins and bases are locked in, the combination is automatically positioned to the zero point. The system uses lubricated and compressed air (6 bar, 85 psi) for release, and springs for clamping. No compressed air is required in the locked, or clamped, position, but a turbo function is available when constant air is possible to increase clamping forces. This is said to accommodate quick, accurate positioning with repeatability less than 0.0005 mm.
The system is wear-resistant, protected against rust and is fully sealed to protect against dirt and swarf. A built-in air cleaning function keeps the clamping system's supporting surface clean and free of chips during change-over. Pull-in/clamp forces for each module can be increased ranging to 45 kN by the turbo function.
The system’s compact design accommodates low fixture height, and modular construction enables easy modification from existing clamping systems.
Affordable indexers and fourth-axis rotary tables greatly enhance the capability of vertical machining centers. It’s almost as good as having a horizontal machining center.
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.
Don't assume the standard chuck is the right workholding for every lathe application.
