Lock-tight FA Quick One Machine Vises

  • Can be clamped easily and speedily with just one rotation using the newly developed mechanical pressure mechanism.
  • The clamping force can be easily set simply by rotating the adjustment knob by hand.
  • The mechanism is designed such that once the clamping force has been set, the vise will only operate at same clamping force, offering stable repeatable operations.
  • Because of the mechanical pressure mechanism, the effect of temperature variations on the clamping force is small, and there is no need to replace consumables such as seals.
  • The sliding jaw and workpiece are prevented from lifting up by an anti-floating mechanism.
  • The main body is made of ductile cast iron, preventing bending and breakage during tightening.
  • Sliding surfaces have been flame heat treated (HRC45) and offer excellent wear resistance.
  • High accuracy that surpasses the former JIS standards grade.
  • Parallel accuracy of matched specification products is within .1.
  • If the handle has interference with the machine table, use the handle joint
    (sold separately).
  • The LTFH type can be used in all kinds of situations by attaching to an angle plate or mounting vertically for horizontal machining centers

＊The shape around the handle insertion point differs in the LTFV-100Q.

 

When ordering parallel products
  • (A and B align 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 products 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. of a vise that you have (stamped on the name plate).
