Japan sanfeng is one of the three famous manufacturers of measuring tools in the world. The high-precision CMM measuring machine produced by sanfeng is a combination of many measuring technologies with high precision and fast motion.

Crysta-apex S series maximum permissible indication error *1 MPEE=(1.7+3L/1000) microns, high precision CNC CMM measuring machine. [500/700/900 series] will MPEE=(2.5+4L/1000) microns

Level c CMM is compared with the crysta-apex S series. It is assumed that the accuracy guaranteed (drawing tolerance) is ±0.02mm, and the accuracy assumed by the measuring machine is less than 1/5 (1/10 is the most ideal), that is, 4 microns, which means that the measurement length is more than 375mm with the accuracy guaranteed by the dimensional tolerance of 1/5. Instead, as shown on the right, crysta-apex

S series has a maximum measurement length of 766mm with the accuracy of 1/5 dimensional tolerance. Due to the difference of 0.8 mu in the initial term, there is a difference of more than 2 times in the ability to guarantee the same accuracy.

The temperature compensation function system (option) can be installed on the crysta-apex S CMM. This ensures the accuracy of CMM mainframe at 16-26oc. This system is based on the joint action of the temperature sensor permanently installed on the grating ruler and the temperature sensor on the workpiece to monitor the grating ruler temperature and the workpiece temperature. Before the measurement results are output to the controller, the expansion coefficient of the workpiece material and the characteristics of the CMM are taken into account to correct the measured value at 20oC. The result of the grating ruler/workpiece combination temperature compensation scheme for crysta-apex S is significantly better than that of the system with only grating ruler temperature compensation.

The maximum drive speed of the crysta-apex S series is 519mm/ S and the maximum drive acceleration is 2309mm/s2. With the general

The CNC CMM measuring machine (maximum drive speed 430mm/s, maximum drive acceleration 1667mm/s2) was compared, and the movement distance produced a difference of about 100mm after one second of movement. Furthermore, compared with conventional CNC CMM measuring machines (maximum measuring speed 5mm/s), the crysta-apex s series determination speed (contact speed with the measuring object) is set to a maximum of 8mm/s, enabling extremely high speed measurements. Combined with the driving acceleration, the total measurement time can be greatly reduced. The larger the number of measurement individuals, the larger the difference, which also indicates the difference in measurement costs.

As with previous models, the crysta-apex S series has adopted a variety of products to increase the rigidity of the airframe

Kind of independent structure. The Y-axis guide, attached to one side of the granite platform, has been missing for years

Changes will maintain the accuracy of the long-term stability, located on the bottom, plus those in the X-axis sliding part before, after,

The upper surface of the air bearing, even at high speed and high acceleration movement can minimize vibration,

To ensure a steady linear motion.
