技術(shù)描述 Technical Description

A. 主機(jī) Machine：

CMM 3D系列三坐標(biāo)測量機(jī)是SRJD公司最新一代高性能移動龍門測量機(jī)。高穩(wěn)定性的測量系統(tǒng)，能夠快速有效地完成通用的車間檢測需要，大大提高了檢測效率。

X向橫梁采用穩(wěn)定的精密矩形橫梁內(nèi)三角設(shè)計，提供最佳剛性質(zhì)量比： 從而保證了平穩(wěn)、精確的運(yùn)動。

Y軸采用高精度直線導(dǎo)軌，提高了測量機(jī)的精度和重復(fù)性。

   Z軸采用大理石材料基座，組裝交叉導(dǎo)軌結(jié)合專業(yè)的精度調(diào)節(jié)達(dá)到空間精度的穩(wěn)定性。

CMM 3D三軸導(dǎo)軌均采用高精密直線導(dǎo)軌，具有相同的溫度特性及剛性，同時，在設(shè)計過程中運(yùn)用了軟件溫度補(bǔ)償和激光補(bǔ)償功能，使得整機(jī)系統(tǒng)具備了改善的抗溫變能力和抗形變/扭擺能力，提高了整機(jī)空間結(jié)構(gòu)的穩(wěn)定性，降低了結(jié)構(gòu)微形變、振動以及溫度梯度變化對測量性能的影響，整機(jī)系統(tǒng)在測量過程中表現(xiàn)出極高的重復(fù)性和系統(tǒng)長期的穩(wěn)定性。

CMM 3Dis the latest generation of moving bridge style Coordinate Measuring Machine (CMM) from REESU. The high stability of measuring system can handle any common shop measurement and inspection tasks, therefore improve your inspection throughput.

Distinctive TRICISIONTM bridge design for X beam provides optimum stiffness-to-mass ratio.  The light alloy bridge is 25 percent stiffer than traditional designs and the X rail has a 50 percent lower center of gravity for smooth, precise movement.  Wider bearing separation than competitive bridge designs assures improved control of bridge axis roll for precise volumetric measuring accuracy, reduced repeatability errors, increased acceleration/deceleration and greater measuring throughput.

Panented precision-machined dovetail guideway in Y axis improves CMM’s accuracy and repeatability. 

From the base machine structure point of view, Function 3D features all-aluminum construction and utilized comprehensive CAD techniques, including Finite Element Analysis (FEA) and Module Analysis, with the result of improved thermal, dimensional/torsional, and geometrical stability and reduce structural deflection and the effects of vibrations and thermal variation on measuring performance. Wrap-around air bearing design optimizes the axis kinematics movement. Therefore the whole system characterizes the optimum measuring repeatability and long-term system consistency.
