| Sodick introduced the first Linear-motor driven Die-sinker EDM and Wire-cut EDM in November, 1998 and installed at users' site over 15,000 units until now. The initial machine accuracy has been maintained for these 8 years. With this trouble-free operation, Sodick has decided to offer 10-year machine positioning accuracy warranty so that the existing users and future customers can operate the machines with confidence utilizing this cutting-edge precision quality. |
The conventional ball-screw driven machines lose its original accuracy in about 3~5 years due to the periodical deterioration caused by ball-screw wear. If try to maintain the original accuracy, users need to replace the ball-screw, costing much expense. However, recent industry requires higher-speed and higher-precision manufacturing. This needs to operate the machines much quicker, resulting in quicker wear of the ball-screw and frequent change of the ball-screw.
| Chronic deterioration is inevitable |  - Thermal expansion
- Need to replace every 3 years to maintain original accuracy
|
| | High-speed, high-accuracy and quick response are maintained |  - No contact
- Original accuracy for ever
- No backlash
- Quick response
|

Sodick's machines are operated through the contact-free linear-motor drive, which helps maintain machine accuracy for over 10 years through this maintenance-free element, while the ball-screw wears and loses accuracy easily.

Moreover, standardized manufacturing system and quality control are in use in Sodick's major plants, where ISO900 are acquired for quality management system. With the trouble-free 8-year operation, of the linear-motors developed and manufactured by Sodick, more confidence is secured about the manufacturing engineering and machine tool accuracy.
