Teach you how to correctly choose a coordinate measuring machine

the coordinate measuring machine contacts the workpiece for measurement through a sensor called a probe, and the obtained data can be combined with the size description of the workpiece or a workpiece feature (such as a hole), so as to realize the electromechanical rotation at a continuously adjustable speed. Through these dimensional descriptions, it is easier to determine whether the workpiece or feature is out of tolerance. This information also provides clues for correcting the abnormal production process that causes out of tolerance

if a CMM is just what you need for your work, how to choose the best one? The first thing to decide is which model of CMM to buy. According to the position of the probe on the measuring machine, there are three basic types: vertical, horizontal and portable

vertical coordinate measuring machine install the probe on the vertical arm. The accuracy of this kind of measuring machine is higher than that of the horizontal measuring machine. Because the bridge structure is more stable and there are fewer moving parts, they have better rigidity and stability, in which cobalt is essential. The vertical CMM contains various dimensions, which can measure the pinion, engine box and even the fuselage of commercial aircraft

the horizontal measuring machine installs the measuring head on the horizontal shaft. They are generally used to detect large workpieces, such as the car body, with a medium level of accuracy

the portable measuring machine simplifies the measurement of workpieces and assemblies that cannot be moved to the measuring machine. The portable measuring machine can be installed on or even inside the workpieces or assemblies, which allows the measurement of internal space and the user to measure at the assembly site, thus saving the time of moving, transporting and measuring a single workpiece

in order to keep the CMM stable, during the design process, the mass and rigidity are generally increased by increasing the cross section of structural components, increasing the distance between air bearings, improving the driving force of the motor, and optimizing the selection of structural materials based on weight and temperature performance, so as to improve the measurement accuracy, repeatability, measurement speed and acceleration. These principles are also applied to some horizontal workshop coordinate measuring machines. This system combines the flexibility of horizontal measuring machines with the high accuracy of vertical design

the direction of horizontal measurement makes the collocation of measuring machine and horizontal machine tool processing equipment more reasonable. They are particularly suitable for measuring large gearboxes and engine housings that require high-precision measurements

The addition of

turntable makes it possible for four axes, and the configuration of two arms can also be realized. All directions of the workpiece can be measured. The horizontal arm configuration makes it easy to load and unload workpieces. The small, workshop type horizontal arm measuring machine is suitable for high-speed production

on the basis of choosing suitable and reliable performance measuring machines, you also need to fully consider the technical strength, application and technical service ability of the measuring machine supplier, whether it has localized technology and long-term comprehensive development strength, and has a large customer base and broad recognition. Through timely and reliable technical service support and spare parts guarantee, it provides guarantee for the long-term and efficient operation of the measuring machine. At the same time, we have professional training and application support teams that may cause pipeline oscillation or leakage, enabling customers to calmly deal with various complex measurement tasks

at present, the hexcon and Zeiss CMM distributed by Lansheng company mainly serve the high-precision measurement of manufacturing enterprises. At the same time, Lansheng company also distributes the economically imported CMM from Weishen, and Lansheng also distributes the Edward economical CMM, which can meet the general measurement accuracy requirements

in addition to selling famous three-dimensional machines, Lansheng also provides three-dimensional accessories such as probe. If the buyer needs it, Lansheng can handle the mortgage and import bidding procedures. (end)
