Description
3 Point Inside Micrometer 87mm – 100mm
SERIES 362
SERIES 362
A precision measuring instrument designed to measure the internal diameter of bores, cylinders, and other similar
features with high accuracy. This tool is commonly used in engineering, machining, and quality control to ensure
that internal dimensions meet specified tolerances. Unlike traditional inside micrometers, the three-point contact
system allows for more stable and reliable measurements, particularly in larger bores.
- 6-12mm graduation: 0.001mm
Steel measuring faces
12-300mm graduation: 0.005mm
Carbide measuring faces - Ratchet stop
- Extension rod are included
- Setting rings are included (Range < 100mm)
How it works:
- Three-point contact: The micrometer has three measuring
points that evenly distribute pressure on the inner surface of the hole, ensuring
accurate and repeatable measurements. - Digital display: The measured diameter is displayed digitally,
eliminating the need for manual reading and reducing the possibility of errors. - Extension rods: These can be used to measure deeper holes.
Applications
- Machining and Metalworking: Used to measure the
internal diameters of bores and holes in metal components, ensuring that
they meet the required specifications. - Quality Control: Essential in inspection processes to
verify the accuracy of internal dimensions in manufactured parts. - Engineering: Applied in various engineering tasks where
precise internal measurements are critical, such as in the design and
fabrication of mechanical parts. - Automotive and Aerospace Industries: Used for measuring
the internal diameters of engine cylinders, bearing races, and other
critical components that require precise tolerances.
Advantages of Three-Point Micrometers:
- Improved accuracy: Ensures precise centering and
measurement compared to two-point micrometers. - Reduced measurement error: Minimizes the impact of
bore irregularities. - Suitable for various shapes: Can be used for both
cylindrical and irregular bores.
