A globalized supply chain platform ensures excellence in every component

The global supply chain platform established based on a global network strictly follows the standards and procedures specified in the quality system to ensure that every component is a high-quality product.

1   Due to the consistency of materials, the all aluminum frame design can achieve consistent deformation of all parts during temperature changes, making it easy to compensate.

2   To ensure the mechanical stability of the measuring machine, small components such as screws and connectors are imported from abroad.

3   Imported high-precision rubber synchronous belt from Germany, with built-in steel wire, balancing flexible meshing and rigid axial transmission, ensuring precise transmission and braking, and eliminating vibration during high-speed movement.

5. High precision air flotation system

Each shaft adopts preloaded air bearings to eliminate the impact of friction and running wear on the machine and be insensitive to on-site dust.

6. Standard process flow

The thick and stable overall granite workbench reduces the impact of vibration, and the flatness of the workbench meets the DIN876 standard.

7. Remote placement of drive motor

Remote placement of motors reduces movement quality and improves speed, while also avoiding the impact of motor heating on machine performance. The patented X-axis reducer mechanism avoids axial twisting and swinging.

8. High precision triangular beam technology

The TRICISIONTM beam design reduces the center of gravity and is lighter than other forms of beams with equal width bearing spans.


Craftsmanship, exquisite from every detail

To ensure mass production under the same standard, CROMA-C adopts standard process flow and equipment during the production process, and extensively uses automated instruments to illuminate the results of manual equipment.
