How to use different coordinate measuring machines correctly? Post time: 2019-10-15 Source: http://www.microaccuracy.com/ CMM involves measurement applications in multiple fields, so there are many types and models of CMM on the market, and different types of three There are differences in the use of coordinate measuring machines. How to use different coordinate measuring machines correctly? In order to meet the precise measurement needs of different situations, there are currently three basic types of CMMs: vertical, horizontal and portable. The specific choice should be considered according to their own measurement needs, their respective characteristics and correct applications. The wonderful machine is briefly described below: 1. The vertical coordinate measuring machine is to install the probe on the vertical arm. The accuracy of this measuring machine is higher than that of the horizontal measuring machine, because the bridge structure is more stable and there are fewer moving parts. , Making them have better rigidity and stability. The vertical coordinate measuring machine includes a variety of sizes, and can measure from pinion gears to engine cases, and even the fuselage of commercial airplanes. 2. The horizontal coordinate measuring machine is to install the probe on the horizontal axis. They are generally used to detect large workpieces, such as the car body, with a medium level of accuracy. 3. The portable coordinate measuring machine simplifies the measurement of workpieces and assemblies that cannot be moved to the measuring machine. The portable measurement can be installed on or even inside the workpiece or assembly, which allows the measurement of internal space and allows users to measure at the assembly site , Thus saving the time of moving, transporting and measuring a single workpiece. 4. In order to keep the coordinate measuring machine stable, in the design process, it is generally increased by increasing the cross-section of the structural components, increasing the distance of the air bearing, increasing the driving force of the motor, and optimizing the selection of structural materials based on weight and temperature performance. Quality and rigidity improve measurement accuracy, repeatability and measurement speed and acceleration. These principles are also applied to some horizontal workshop-type coordinate measuring machines. This system combines the flexibility of the horizontal measuring machine with the high precision of the vertical design. 5. The direction of horizontal measurement makes the collocation of three-coordinate measuring machine and horizontal machine tool processing equipment more reasonable. They are especially suitable for measuring large gearboxes and engine housings that require high-precision measurement. The addition of the turntable makes four axes possible, and the dual-arm configuration can also be realized, and all directions of the workpiece can be measured. The horizontal arm configuration makes it easier to load and unload the workpiece. The small, workshop-type horizontal arm three-dimensional measuring machine is used in the high-speed production process. The operation has a great influence on the accuracy of the coordinate measuring machine, so the operator must master the correct use of the coordinate measuring machine, and adopt appropriate measurement methods according to the situation of the workpiece. Miaoji Technology is a professional measuring equipment Manufacturers currently have a variety of high-precision testing equipment such as three-coordinate measuring machines and one-button measuring instruments that can be provided at a discount!
