The INSIZE 3280-100A Non-Rotating Spindle Universal Micrometer is a precision mechanical measuring instrument designed for versatile outside-dimension measurement in machining, manufacturing, inspection, and quality-control applications. It provides a 75–100 mm measuring range, 0.01 mm graduation, and 5 µm accuracy, making it suitable for precision measurement of shafts, machined components, cylindrical parts, and other external dimensions. Its non-rotating spindle helps maintain the orientation of the selected measuring tip during spindle movement, while the ratchet stop supports consistent measuring force. The micrometer is supplied with 7 pairs of interchangeable anvil/spindle tips, providing flexible measurement options for different workpiece geometries.
Key Features
1. 75–100mm Measuring Range
The 3280-100A offers a 75–100 mm measuring range, making it suitable for measuring larger external dimensions such as shafts, cylindrical components, machine parts, and precision-machined workpieces.
2. 0.01mm Graduation & 5µm Accuracy
The micrometer provides a 0.01 mm graduation and 5 µm accuracy, supporting detailed and repeatable dimensional inspection in machining, manufacturing, and quality-control environments.
3. Non-Rotating Spindle
The non-rotating spindle design helps prevent the spindle measuring contact from rotating as the spindle advances. This is useful when using specialized measuring tips and when maintaining consistent contact orientation is important.
4. 7 Pairs of Interchangeable Measuring Tips
The 3280-100A is supplied with 7 pairs of anvil/spindle tips, including flat, spherical, spline, disk, blade, knife-edge, and point configurations. This allows the micrometer to be adapted for different measurement applications.
5. Ratchet Stop & DIN 863-3 Design
The integrated ratchet stop helps provide consistent measuring force, supporting repeatable readings. The 3280 series is designed to meet DIN 863-3 requirements. Setting standards are supplied for applicable measuring ranges; the 0–25 mm model is the exception.
