LOCK-TIGHT HYDRAULIC MACHINE VISES MK III

Feature

  • The total length is 125 mm shorter and the weight is 7 kg lighter than the conventional type. Furthermore, offers a mis-operation prevention mechanism where the hydraulic and manual switch is toothed.
  • Made of ductile cast iron, minimizing bending and breakage during tightening.
  • Sliding parts have been flame heat treated (HRC45) and offer excellent wear resistance.
  • The hydraulic pump is finished as a pump that is capable of powerful clamping with low trouble from over 3, operational tests.
  • The optimal jaw opening from 3 positions is obtained by adjusting the position where opening and closing starts.
  • High accuracy that surpasses the former JIS standards grade.

Clamping Method


(1) Clamping method by hydraulic pressure

・With the matching parts of the switching collar and socket separated, rotate the handle in the clockwise direction.
・The jaw plates touch the workpiece, and the internal clutch engages with a clamping force of approximately 10 kN.
・After the clutch has engaged, only the handle and socket rotate, and the hydraulic clamping operation is performed.
・Clamping force and handle operation (after the clutch is engaged)

 

 

 

Handle Operation 3 marking lines (Rotation)1234
Clamping Force (kN)12203040

・The clamping stroke by hydraulic pressure is approximately 1.8 mm.

 

(2) Clamping method by screw

・Slide the switching collar towards the socket side, and with the switching collar and socket interlocked, rotate the handle in the clockwise direction.
(While interlocked, the clutch does not operate).
・Clamping by screw has a maximum of approximately 10 kN.

(3) Combination of clamping by screw and clamping by hydraulic pressure

・When clamping workpieces that deform easily and workpieces where the workpiece surface is a cast surface, perform clamping using the screw and then perform clamping using hydraulic pressure.
・Perform the clamping operation by screw as shown in (2) and then perform clamping by hydraulic pressure as shown in (1).
・The clamping force is (clamping force by screw) + (clamping force by hydraulic pressure).
・For workpieces where large deformation may occur, check that the workpiece is securely fixed after clamping.
