1, image measuring instrument structure design is simple, generally lift linear guide, table movement using light bar drive, the measurement range can be done according to customer needs to a large.
2, tool microscope design precision and compact, with CCD camera channel, retaining a purely optical measurement system, with objective and eyepieces for observation and measurement, transmission using bearing guide, screw drive, metal grating, high measurement accuracy, with software, with a variety of accessories can be done a lot of measurement work. (Light rod transmission structure is simple, but the transmission thrust is small, poor positioning accuracy, silk rod transmission positioning accuracy, wear resistance.
Second, the measurement operation is different
1, the image measuring instrument products for the measurement of flat two-dimensional workpiece, measurement speed is faster, the software has more features, basically all measurements are done by the software.
2, tool microscope measuring range, part of the parts of the measurement needs to be completed through the accessories, high-magnification objective lens can also be height measurement, the operator has certain technical requirements, with software with all the functions of the image measuring instrument.
Third, the measurement range is different
1, the image measuring instrument is suitable for measuring flat two-dimensional workpiece. But for the measurement of columnar parts, such as: threads, screws, tools, etc., the measurement is not convenient, not accurate enough, or even impossible to measure.
2. Tool microscope has a wide measuring range, and can be equipped with a variety of accessories such as indexing head, height measuring device, round table, positioner, ejector holder, etc., and it is more accurate to measure two-dimensional or cylindrical parts.
So, for flat workpieces, and precision requirements are not high, the first choice of image measuring instrument.
For high precision requirements, especially the product measurement process requires a second focus, cylindrical parts, preferred tool microscope.
