Internal groove micrometer – SA900GT

The internal groove micrometer is an instrument designed to measure the depth of internal grooves inside bores and mechanical components when a specific inspection is required that cannot be carried out with a standard internal micrometer. It is a useful solution in workshops, tooling departments and quality control whenever the dimension to be checked concerns the depth of an internal groove.

The distinctive feature of this instrument is its measuring configuration, developed to work inside the bore and correctly reach the groove. This makes the instrument particularly suitable for applications where the depth of an internal groove must be inspected using a dedicated measuring solution capable of working in restricted spaces and on geometries that are difficult to access with more traditional systems.

One of the most important aspects is the 2-direction measurement capability, meaning the possibility to work both in pull and push direction. This makes the micrometer particularly interesting for inspections on internal grooves, because the dimension can be checked according to the required measuring direction of the application.

Compared to a groove depth gauge, the internal groove micrometer provides inspections with higher accuracy, an important aspect whenever the groove depth must be verified with greater reliability.

From an operational point of view, this micrometer is suitable for repetitive inspections on internal grooves and internal recesses while maintaining simple reading and practical instrument handling. The 0.01 mm resolution makes it suitable for inspections commonly required in many mechanical applications, while the measuring structure helps reach internal areas where the dimension to be checked is not easily accessible.

In practical applications, the groove micrometer is recommended for those who need to inspect internal groove depths both in pull and push direction using an instrument specifically developed for this type of measurement. It is particularly useful when continuity of use, direct dimensional control and fast reading during inspections are important.

FAQ – Internal groove micrometer

What is an internal groove micrometer?
It is a measuring instrument designed to inspect the depth of internal grooves inside bores and mechanical components.

What is an internal groove micrometer used for?
It is used to measure the depth of internal grooves when a standard internal micrometer is not suitable for this type of inspection.

What does 2-direction measurement mean?
It means the micrometer can work both in pull and push direction, allowing groove depth inspection according to the required measuring direction.

Why is it useful to work both in pull and push direction?
Because this type of instrument adapts better to inspections on internal grooves, providing more practical control consistent with the groove geometry.

What is the difference between an internal groove micrometer and a groove depth gauge?
The internal groove micrometer is a more specific instrument for this type of inspection and provides higher accuracy compared to a groove depth gauge.

What resolution does this micrometer have?
The resolution is 0.01 mm, making the instrument suitable for centesimal resolution inspections.

In which applications is this micrometer useful?
It is useful in mechanical workshops, tooling departments, production and quality control whenever internal groove depths on mechanical components must be inspected.

Who is this instrument recommended for?
It is recommended for those who need to inspect internal groove depths using a dedicated instrument designed to work both in pull and push direction.

What are the most common mistakes with this type of measurement?
The most common mistakes are incorrect positioning of the instrument, dirty surfaces, incorrect interpretation of the dimension to be checked and using an instrument not suitable for the internal geometry of the component.
