Summary: Supporting
workpieces at a consistent height.
Parallels are
precision metal bars used in machining to provide a stable and level support
for workpieces. They are typically made of hardened and ground steel to ensure
accuracy and flatness.
Function: Parallels are used to:
* Raise a workpiece in a vise or on a
machine table so that it can be machined without interference from the vise
jaws or table surface.
* Provide a level and consistent base for
supporting workpieces during machining or measurement.
* Ensure that a workpiece is held parallel
to the machine table or cutting tool.
Use: They are
commonly used in:
* Milling machines
* Grinding machines
* Drill presses
Types: Parallels come in matched sets, meaning each pair within a set has the same height within very close tolerances. This ensures that the workpiece is supported evenly.
