Grip Down Chuck Applications


GMT Grip Down (Pull Down) Chuck is ideal for finishing operations. The radial and pull-back function of the chuck ensures:



Advantages of Lapping

Advantages of Lapping


  •  Improves surface finish by eliminating the peaks and valleys.
  • Create maximum bearing area between the mating surfaces.
  •  Improves service life of the moving parts which are subject to wear.
  • Improves geometrical and dimensional accuracies.
  •  There is absolutely no distortion in the component after lapping since no clamping devices are used.
  • Minimizes the necessity of re hardening hardened parts because of less heat generation.
  • Accessible flat surfaces of parts of any shape and size and any type of material can be lapped.
  • Simple carrier plate design is enough to accommodate the component for lapping (i.e.) complicated fixture is not required.
  • Any unskilled operator can work on the machine.
