A precision measuring tool reading micro-displacements via pointer swing, with 0.01mm precision. Commonly used for machine tool accuracy calibration and workpiece geometric tolerance inspection (e.g., roundness, perpendicularity), crucial for dimensional and geometric accuracy control in machining.
Engine cylinder inspections and hydraulic component production require dial bore gauges. These devices are specific to measuring internal diameters, and use a three-point contact technique spaced to 120 degrees, giving roundness accuracy of ±0.005mm. The device extends the measuring range using a telescoping rod (between 30mm-500mm) and the dial indicator fulfills the requirements of precision, delivering accuracy of 0.01mm. While they are pivotal for proper fitting of seals and bearings, they are also critical.
Frequently Asked Questions
How do magnetic bases aid dial indicator use?
Strong rare-earth magnets (holding force ≥50N) enable hands-free operation on ferrous surfaces, reducing fatigue during prolonged inspections like CNC machine calibration.
Dropped from 1.5m without damage, the stainless steel frame proved rugged. The shock-absorbing mechanism maintained accuracy in foundry environments, where vibrations are constant.
Swivel bezels allow instant zero resetting in any orientation, improving efficiency during multi-point measurements. Critical for repetitive quality control checks in production lines.
Data Logging Capability
Digital dial indicators with USB output store up to 1000 readings, supporting statistical process control (SPC) and ISO 9001 compliance. Ideal for traceable inspections in aerospace and medical device industries.
Cost-Effective Inspection
Provides professional-grade precision at a lower cost than digital alternatives, making it a staple in small machine shops, educational labs, and maintenance departments.
