Features
Excellent machining accuracy
Based on the highly rigid and highly accurate mechanical structure including the table, sliding surface, and feed axes, this product pursues high machining accuracy from all aspects, such as improving positioning accuracy and reducing the effects of thermal displacement. The S series achieve JIS class 5 [JIS B1702 (1998)] for high-precision gears (spar gears).
In addition, repeatability of processing precision is guaranteed to be Cp=1.33 for an overball diameter tolerance of 50 μm using thermal displacement compensator. S series meet the needs of high precision and can handle even challenging orders with reliable quality.
Stable machining quality
Stable machining quality is maintained by thorough measures against thermal deformation.
When cutting oil becomes heated during the machining process and splashes over the surface of the machining bed, the workpiece may experience dimensional variations due to mechanical thermal displacement.
To prevent this, some coolant is circulated within the bed to maintain uniform thermal distribution, minimizing thermal displacement.
