AUBAT标准曲率半径R是计量校准检定轮廓仪、粗糙度仪、台阶仪、三坐标测量仪、成像扫描仪等必备的标准器具。
  The standard curvature radius R of AUBAT is a necessary standard instrument for measuring, calibrating / calibrating profilometer, roughness meter, step meter, three coordinate measuring instrument, imaging scanner and so on.
  
 特点：
1.曲率精度高 精度误差≤0.001mm
2.球体表面光洁度粗糙度极低 Ra4-8nm(纳米）
3.硬度必钢高 RC等于78
4.不易变形 热膨胀系数低，弹性模量高，优于钢数倍
5.绝缘无磁性，对仪器磁干扰为0 
Characteristic：
1. high precision curvature error less than 0.001mm
2.The roughness of the surface of the  sphere is extremely low Ra4-8nm (nanometer)
3. hardness must be steel RC equal to 78
4. the coefficient of thermal expansion is low, and the modulus of elasticity is high, which is better than that of steel.
5. insulation is non magnetic, and the magnetic interference to the instrument is 0
