This document introduces precision measuring tools for manufacturing and quality control. It explains how to choose dial indicators, digital calipers, and micrometers based on application needs.
This document is a product guide for professionals in manufacturing, machining, engineering, and industrial inspection. It introduces precision measuring tools from Fowler High Precision, focusing on dial indicators, digital calipers, and digital micrometers for quality control and tolerance verification.
The first section covers dial indicators, describing their use in machine shops and quality-control departments for measuring small movements, flatness, runout, and alignment. It mentions features like adjustable bezels, tolerance markers, and contact points, and advises on selecting measuring range, graduation, and mounting compatibility.
Next, the guide discusses digital dial indicators, which offer electronic displays for easier reading. It highlights features such as unit conversion, zero setting, and data output, and recommends evaluating resolution, repeatability, and display readability for repetitive inspections and machine setup.
The document then explains digital test indicators, which use a pivoting lever for checking runout, alignment, and parallelism in confined spaces. It covers lever orientation, measuring range, and environmental protection, noting options for demanding machining environments.
A section on digital calipers follows, detailing their versatility for outside, inside, step, and depth measurements. It advises comparing jaw design, measuring capacity, resolution, and dust or moisture protection to match workpiece dimensions and workflow.
The final section focuses on digital micrometers for fine dimensional measurement, emphasizing their precision screw mechanism and electronic readouts. It reviews measuring range, resolution, spindle and anvil design, and calibration needs, concluding with guidance on choosing the right instrument for tight tolerances.
