Clamping glossary
2+2 self centering-compensating clamping: Work pieces need to be centered when clamping. When using 3 jaw chucks, this is carried out via a mechanical synchronizing of the 3 jaws to one common center. A self centering 4 jaw chuck which is used for different work piece geometries is creating 2 separate centers via the 2 opposed jaw sets. The mechanical synchronizing is causing a redundant positioning, which affects the clamping negatively. The Centco4-MLW with its 2+2 self centering-compensating clamping centers the work piece with 2 independent axes. The self centering 2 axes work independent from each other, and thus can reach one common center. This works with any work piece geometry or tolerance. The grip force is only built up, after both jaw axes have reached their common center. This guaranties a very sensitive and high accurate clamping at any grip force and best machining results.
Weight optimized chuck body: The outer geometry of the chuck body has recesses between the base jaws. This improves the radial accessibility with live tools and reduces the inertia and weight. The machine can accelerate and decelerate quicker and more energy efficient, and the machine spindle can carry higher work piece weights. Centrifugal compensation: The rotation of a chuck results in cen- trifugal forces that act onto the master jaws and the top jaws. It reduces the Static grip force, and thus reduces the dynamic chip re- moval. The centrifugal force system of the Centco4 MLW reduces this effect, and thus improves the dynamic chip removal, the safety and the roundness of the work pieces. Direct pressure lubrication system: In a pressure lubrication system all loaded areas are directly lubricated via direct channels. Used lubricant is directly replaced by new lubricant. Compared to open lubrication systems it reduced the amount of lubricant nee- ded, increases the lubrication intervals and avoids tribo corrosion.
