This article will help you understand the current popular profile measuring machine, its applications, uses and effectiveness.
Contour measuring machine for beginners
Profile Projector is a specialized device that uses the principle of projecting an image of an object onto a screen to perform dimensional measurements visually and accurately. This device is often used to check small details, where conventional measurement methods are difficult to ensure the necessary accuracy.
Thanks to its fast and non-contact measurement capabilities, profile projectors have become a powerful support tool in modern manufacturing environments, especially in product inspection, R&D or component quality assessment right on the production line.
Wide application of profile measuring machine
This device is widely used in many different manufacturing fields. In the automotive industry, it supports the precise inspection of details such as gears, bearings, cylinders or frames. In the plastics industry, the device helps to measure the shape of plastic and rubber components easily.
In addition, in the telecommunications industry, the machine is used to check the contour of wires, cables and other small accessories. The device also plays an important role in the medical equipment industry, where high precision and stability in every detail are required.
How to use a profile measuring machine
Measure length/width
First, place the specimen on the machine table and adjust the table height so that the image is clearly projected on the screen. Then, rotate the object or machine table so that the edge to be measured is parallel to the reference line displayed on the screen. Next, set the X and Y axis values to 0 at the first position.
Move the machine table with the control handle to the end point of the section to be measured, and realign it with the reference line. The displacement of the machine table is clearly displayed on the digital ruler according to each X or Y axis, which is the measurement result of length or width. In the case of one-way measurement, just use the displacement parameter corresponding to that axis.
Measure diameter/radius
Start by adjusting the height of the table to focus the image of the circular part to be measured on the screen. Align the center of the circle with the center of the screen or reference line. For radius measurements, set 0 at the center and move the table to the edge of the circle to record the distance. For diameter measurements, measure from one edge to the opposite edge, recording the total distance traveled.
Typically, the diameter or radius is measured in four perpendicular directions for increased accuracy. Alternatively, a concentricity chart placed on the screen can be used to assist in the measurement. For machines with automatic calculation functions, simply select three points on the edge of the circle and the machine will process and give the result immediately.
Measure angle
The simplest way is to rotate the machine table along the θ axis so that the edge or line on the projected image coincides with the reference line on the screen, then read the rotation angle from the system. In addition, users can also place the “chart” scale plate with pre-engraved angle arcs on the screen to observe and estimate the measurement angle.
For models that support the calculation function, the operator only needs to select two straight lines forming the angle, the system will process and give the exact value of the measurement angle, saving time and increasing consistency in the inspection process.
