Vices - the universal
fastening of workpieces
With a vice, the workpiece
is clamped between two jaws. With the classic vice, one jaw is fixed, while the
other can be moved using a crank using a threaded spindle.
In order to counteract
damage to the jaws, replaceable jaws can also be attached. These can be made of
aluminum or plastic.
What types of vices are
there?
The parallel vice is the
most common type. Thanks to the guide rail, the two jaws are always parallel to
each other. The tension is evenly distributed. Parallel vices are equally
suitable for small and large workpieces. Parallel vices, like table vices, are
very often found in hobby workshops. Do-it-yourselfers appreciate these as
universal and indispensable helpers.
As the name suggests, the
machine vice is designed for working with machines. Thanks to its compact
design, it can be used in machine tools such as milling machines and drilling
machines. Machine vices enable precise work. Machine vices are available in
hydraulic or pneumatic versions. This means that cranks can be removed and
collisions with tools are avoided.
Further variants are the
pipe vice and the mini vice.
Which criteria are
important for the purchase?
Once the area of
application has been clarified, for example in the hobby workshop or use in a
machine tool, size, jaw width, material, adjustability and additional equipment
play an essential role. The larger the jaw width, the larger the workpiece can
be. Made of forged steel, for example, it is very robust, while cast vices made
of steel or gray cast iron are not quite as resistant, but do their job
effortlessly in the hobby area. The vice should be height-adjustable for the
optimal working height.
