Each vise has a similar structure


Each large or small single vise is built very similar. Twelve components provide the flexibility and fixing force to machine all kinds of workpieces. The heart of the vice is a threaded rod in the middle of the auxiliary tool. Older vices are often made of cast iron, modern variants of forged steel.

Eleven (cast iron) or twelve (forged steel) components

When looking at a vice, the rotary lever and the two jaws fall first into the eye. The overall structure consists of these three components and nine other construction elements.

  • Rotary lever or spindle crank: A vertically movable lever is mounted in the turret. It is designed so that the function can not be damaged with physical strength.
  • Movable front jaw: The front jaw is firmly connected to the guide rail and "moves" according to the movement.
  • Fixed rear jaw: The rear jaw serves as an immovable with the vice body connected abutment for the Einspanngut.
  • Lever or spindle bearings: Attached to the turret, located inside the structure of the front jaw, is the bearing for the front end of the guide rail.
  • Guide rail: The bearing is followed by a rod-shaped shaft that leads horizontally under the rear clamping jaw to the trapezoidal thread.
  • Trapezoidal threaded rod: The rotary thread is "cut in" in the rear end of the shaft and evenly distributed by its trapezoidal shape.
  • Spindle chuck or nut: The spindle chuck or a nut forms the counter bearing for the rotary thread.
  • Anvil surface: In the case of vises made of forged steel, a small flat surface is attached above the nut at the end of the rear jaw. It serves as a moderately strong playing surface.
  • Pipe clamping wings: Underneath the jaws in the "stems", rounded steel noses are located at about half the height of the wings to enable the clamping of round workpieces such as pipes.
  • Guide Bearing Lugs: Steel side rails on both sides provide rails for horizontal movement of the guide rail.
  • Guide adjustment screw: A set screw is usually inserted in a tab, allowing more or less lateral guide play.
  • Guide stabilizing rail ends: The extensions of the guide rail ends ensure the stable position of the guide in every degree of untwisted condition.

Tips & Tricks

Depending on the manufacturer, the attachment points for vices are not the same for all models. In some variants, the screw holes for the workbench are integrated in the tabs. Be sure to make four point screw connections.
