The 2-dimensional measuring machine, also known as the secondary element measuring instrument, is an instrument and equipment used to measure the dimensions of products and molds. Secondary measuring instrument, or called video measuring instrument and video measuring machine, is used to measure the measured elements of the shape and positional tolerance, such as position, concentricity, straightness, contour, roundness and dimensions related to the reference, etc., the second element is mainly used for the more Pu products (such as shrapnel) and smaller products of the two-dimensional plane inspection or other workpiece two-dimensional projection detection.
Can measure any geometric dimension on the plane, including diameter, radius, length, angle, width, height, depth, point to point distance, point to line distance, center distance and so on.
Main application:
For measuring two-dimensional plane dimensions, widely used in a variety of different precision industries. It is mainly used in calipers, angle ruler is difficult to measure or simply can not be measured, but in the assembly plays an important role in the size of the parts, angle, etc., such as silicone, circuit board creepage distance, electrical clearance, the control panel of the lamp holes, plastic parts of certain dimensions and so on.
Can also be used for some parts of the picture for the analysis of the cause of bad photos. As the image measuring instrument is the use of surface light or contour light illumination parts obtained by the image, the measurement of the parts need to take points, solid not all parts measured using a quadratic measuring instrument is the most precise, select the best method, the most effective way to measure the size of the parts most accurately.
