Used profile projector for sale (18)

A profile projector, also known as an optical comparator, is a device used in the manufacturing and inspection of parts where the silhouette of a complex shape is projected onto a screen at a precise magnification. It is primarily used for checking shapes and sizes of manufactured parts against specified templates.

Functionality

The profile projector magnifies the shape of a part so it can be compared with a predefined template, which can either be drawn on the screen or superimposed digitally. It measures dimensions and angles by tracing the silhouette of the sample with a vertical or horizontal light source, thereby creating a sharp, defined shadow.

Applications

This device is frequently utilized in quality control to inspect tool wear, verify the dimensions of tooling, and intricately analyze small parts for industries such as metalworking, electronics, and plastics. It is especially useful in ensuring the accuracy and precision of components where small dimensions and complex shapes need to be verified regularly.

Advantages of Using a Profile Projector

The primary benefit of using a profile projector is its ability to provide accurate, repeatable measurements quickly. This non-contact method of inspection reduces the risk of damaging parts during measurement and is particularly effective for delicate or small items. Additionally, the visual screen display allows multiple users to view and discuss the analysis, facilitating better communication within quality control teams.
