The JONES & Lamson EPIC 30 Comparator Machine is a high-precision optical comparator primarily used for dimensional inspection, measurement, and quality control in manufacturing processes. Below is a technical breakdown of its use, features, and functionality:

Primary Uses

1. Dimensional Inspection:
   • The EPIC 30 is designed to project magnified images of a workpiece onto a screen, enabling precise measurements of part geometry, dimensions, and tolerances.
   • It is particularly useful for non-contact measurement, reducing the risk of part deformation.
2. Measurement of Complex Profiles:
   • Ideal for inspecting intricate profiles, contours, and geometric tolerances such as radii, angles, and curves.
   • Frequently used in the aerospace, automotive, medical, and tool-and-die industries for parts requiring stringent tolerances.
3. Tool Verification:
   • Ensures the accuracy of cutting tools, gauges, and fixtures by comparing their profiles to a predefined standard or blueprint.
4. Batch Inspection:
   • Allows for efficient inspection of multiple parts in a production batch, ensuring consistency and quality across all units.

Technical Features

1. Optical Projection System:
   • Projects the silhouette of a part onto a screen at a specific magnification level (e.g., 10x, 20x, 50x, or higher).
   • The projection lens ensures distortion-free magnification, crucial for precise measurements.
2. Screen and Scale:
   • Features a 30-inch circular viewing screen, making it suitable for inspecting large parts or multiple smaller components simultaneously.
   • Equipped with engraved angular and linear scales for direct measurements on the screen.
3. Edge Detection and Illumination:
   • Integrated edge detection enhances visibility of part boundaries, enabling accurate measurement of edges and transitions.
   • Uses high-intensity halogen or LED lighting systems for both front and back illumination to highlight contours and surface features.
4. Digital Readout (DRO):
   • Many EPIC 30 models include a digital readout system for precise coordinate measurements, reducing the chances of human error during manual readings.
5. Stage Travel:
   • Offers a motorized or manual stage with X and Y travel for positioning the part under the lens.
   • Precise micrometers or linear encoders measure stage movement, correlating to part dimensions.

Advantages

1. High Accuracy:
   • Maintains high precision, typically within microns, making it suitable for applications requiring extreme dimensional control.
2. Non-Contact Measurement:
   • Eliminates physical contact with parts, ideal for fragile, delicate, or soft materials.
3. Versatility:
   • Capable of inspecting parts made from various materials, including metals, plastics, and composites.
4. Ease of Use:
   • Simple, intuitive operation suitable for operators with varying levels of technical expertise.
5. Cost-Effective Quality Control:
   • Provides reliable inspection and measurement capabilities without requiring high-end CMM (Coordinate Measuring Machine) systems.

Common Applications

1. Inspection of Machined Parts:
   • Gears, shafts, bearings, and other machined components.
2. Mold and Die Verification:
   • Ensures that molds and dies meet design specifications.
3. Electronics:
   • Inspects PCB boards, connectors, and other small components for dimensional accuracy.
4. Aerospace and Automotive:
   • Validates complex parts critical to performance and safety, such as turbine blades or precision-engineered fasteners.

The JONES & Lamson EPIC 30 Comparator Machine remains a cornerstone in precision metrology for industries that demand high accuracy and repeatability. Its robust optical system, precise measurement capabilities, and adaptability to a range of applications make it indispensable in modern manufacturing.
