Schunk Clamping Force Block Provides Automation Entry Point
Schunk’s Tandem PSG3-LH 100 clamping force block provides a low-maintenance solution for transitioning into automation for basic aluminum and plastics machining applications.
Schunk says its pneumatically actuated Tandem PGS3-LH 100 clamping force block for stationary workpieces is a simple, low-maintenance entry point to automation. The Tandem PGS3-LH 100 can be directly mounted via the integrated flange on the machine tables, dividing heads or Schunk Vero-S NSL3 150 clamping stations of machining centers. Its compact and square design ensures optimum accessibility and enables a stroke of 6 mm per jaw.
Due to its clamping force of 4,500 N and repeat accuracy of 0.02 mm, Schunk recommends the low-maintenance Tandem PGS3 for basic applications in aluminum and plastics machining. Special quality features include a chip-repelling design, surface-treated components in the power flux and long base jaw guidances that avoid lifting the chuck jaws. The vise is compatible with all standard top jaws with tongue and groove (KTR, KTR-H) from Schunk’s extensive chuck jaw program. Users can incorporate the vise into any machine tool with its lateral air connections and built-in keyways.
These vise jaws use protruding, mechanical pins to repeatedly support workpieces either horizontally or at angles. They are said to allow quicker setups than conventional parallels.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
Don't assume the standard chuck is the right workholding for every lathe application.
