LOCK-TIGHT PRECISION MACHINE VISES

Feature

  • The sliding jaw and workpiece are prevented from lifting up by an anti-floating mechanism.
  • Made of ductile cast iron, preventing bending and breakage during tightening.
  • Sliding parts have been flame heat treated (HRC45) and offer excellent wear resistance.
  • High accuracy that surpasses the former JIS standards grade.
  • Even in the rare case that it becomes worn out, it can be dismantled and the accuracy can be restored easily.
  • Parallel accuracy of matched specification products is within .1.

Accessories

Ordering Parallel Products


(A and B can be aligned within 0.01 no matter how many pieces)
If the suffix of the manufacture no. (attached to the outer box and main body) is the same letter, then the product are parallel no matter how many pieces (for standard guide blocks). There is no charge for parallel products.

◆When purchasing for the first time
Order matched specification products (suffix G) When ordering, specify the groove width of the machine you are using.

◆For additional orders
Contact us with the suffix letter of the manufacture no. (stamped on the name plate) and the guide block width of a vise that you have.

 

Increasing the Jaw Opening


A large jaw opening can be obtained by changing the jaw plate positions.
