In the mists of the distant past, whoever came upon the idea of fixing items to be worked on in such a way that they would not move under the pressure of sawing, filing and boring, is unknown. The astonishing fact is that today in the computer age, the shaft vice as a purely mechanical tool is indispensable; and no workshop crammed with electronic devices can do without it. A decisive step in the development of this indispensable tool into its present form was the replacement of clamping techniques using wedge and hammer by clamps with threads in the middle ages. The disadvantage: the moving jaws could only be guided radially so that the clamped items would more less tilt. It was only with the introduction of the shaft vice in 1750 on which the movable jaws were guided on horizontal adjustable slots that a breakthrough was made to the optimal application.
In 1830 in England the first cast iron vice was produced. Liquid iron could be transformed into any shape easily. When pouring, air pockets often occurred within the cast. The structure was therefore porous and brittle. The result: insufficient resistance for harder tasks, causing breakage. For this reason, for example, parts vital for safety in the car industry and high-grade unbreakable vices are made of steel. The structure of the steel is made homogeneous through forging. With the introduction of the jackhammer with its heavy hammering capability and the use of forges with strict tolerances, the problem of accurate shaping was solved.
After the second world war at the time of the German recovery, shaft vices were in greater demand than ever. Among other things, the etiquette "Made in Germany" for technical products made for worldwide success. Shaft vices have been made in Germany alone for more than 80 years. Advanced production methods, particularly in welding and forging, spurred the inventor to seek a new patent in 1948. Today’s shaft vices are based on the concept of this patent.
In parallel to the perfection of the production methods, technicians worked on the improvement of models according to the principle: "small details have great consequences". Through a pressure disc, spring and snap ring for example, the spindle was thus positioned so that lost motion was eliminated. These days the shaft vice has a centrically adjustable guide, forged jaws as standard, a protected spindle location, and, because of its slimness due to its drop forged guide rails: an advantageous low clamping capability.
● Compact Toggle Shaft Vice
A compact toggle shaft vice is a kind of vice that is made small sized, and is a do it all shaft vice suitable for gripping, cutting shafts, shaft extraction, and much more where holding the shaft securely is a must. This shaft vice is offered with three separate sets of rubber jaws: V shape, round, and aluminum. A compact shaft vice is made of rigid extruded aluminum frame, and has a powerful toggle clamp that can hold up to 500 lbs. The clamping pressure is adjustable, and has an automatic jaw return. Interchangeable jaws or installed, along with vulcanized rubber round jaw pads for gripping, vulcanized rubber V pads for shaft doctoring, and aluminum V pads for heavy hacking.
● Self Centering Shaft Vice
Self centering shaft vices have both jaws that move in equal and opposite directions so parts of varying size remain centered. These kind of vices are used on milling machines , grinding machines, drilling machines and CNC machining centers. The adjustable sliding rods enable the workpieces to remain set in the same position. The prism is double sided with the possibility to reinstall. The shaft vice can be installed on the side surface of the base, and is fitted with ball bearings.
