cilinderplug

A cilinderplug, also known as a cylinder plug or plug gauge, is a precision measuring instrument used to determine if a hole or a bore is within a specified tolerance. It is a go-no-go gauge, meaning it has two distinct ends, one designed to fit into the hole if it is within the acceptable size range (the "go" end) and the other designed not to fit if the hole is too large (the "no-go" end).

The "go" end of the cilinderplug is manufactured to the maximum allowable size of the hole. If this end can be fully inserted, it indicates that the hole is not too small. The "no-go" end is manufactured to the minimum allowable size of the hole. If this end cannot be inserted, it confirms that the hole is not too large. If the "go" end enters and the "no-go" end does not, the hole is within the specified tolerance.

Cilinderplugs are typically made from hardened tool steel to ensure durability and accuracy. They are essential tools in manufacturing, machining, and quality control for ensuring the interchangeability of parts and the proper functioning of assemblies. They are used to measure internal diameters of holes, cylinders, and other cylindrical features. The specific dimensions and tolerances of a cilinderplug are determined by the engineering specifications of the part being inspected.
