ROEMHELD QIS V Jaw Inserts

ROEMHELD Precision Vises

Product Information

V Jaw Inserts are used together with base jaws as part of our Quick Insert System (QIS). These precision downthrust jaws have two 120° V grooves, to allow clamping cylindrical workpieces in either horizontal or vertical position. V Jaw Inserts are usually mounted on the fixed-jaw side (for positional accuracy), together with a Plain Jaw Insert on the sliding-jaw side. V Jaw Inserts can also be used in pairs.

QIS is our patented system of downthrust vise jaws, consisting of several different quick-change jaw inserts that mount on a single base jaw. Jaw inserts are held in place by a guide pin and two permanent magnets (V Jaw Inserts have a bottom groove instead of a guide pin for precise sideways location on the vise guideways). Jaw inserts can be changed in a few seconds. The base jaw and jaw inserts have a matching angle between them to provide downthrust action. This downthrust effect ensures that the workpiece is held firmly down against the vise to a precise zero point, providing extremely accurate height location.

Available in three jaw widths, to fit the following vise sizes:

100mm

125mm

160mm

Data Sheet

Mounting

Base jaws are firmly fastened to the vise using two socket-head cap screws. To install V Jaw Inserts, slide insert toward the base jaw with the bottom groove engaging the vise guideways, until the insert is held by the permanent magnets. To remove, pull the jaw insert upward until the guide pin reaches the top of the slot, then tilt the insert forward to overcome the retention force of the permanent magnets.
