1 Accuracy
Scraping
for accuracy
“Aiming for 1 μm”
In order to challenge areas that are impossible with only machining and to make machines with perfect linear axes, YASDA continues to utilize the scraping process.
Temperature control
for accuracy.
In order to assemble the high accurate parts finished by scraping, it is important to suppress temperature changes in the factory during assembly.
At YASDA, the temperature in the factory is thoroughly controlled, and the temperature change in 24 hours is kept within 0.5℃. The temperature difference between the floor surface and 5 meters from the floor is kept within 0.6℃.

2 Rigidity
Guideway
for rigidity
The highly rigid box guideway is fixed to the mounting surface, which is straightened by scraping. This improves vibration damping and achieves both high rigidity and high precision.
Construction
for rigidity
The total weight of the machine supporting a 100kg workpiece is 8,000kg.
The logic of machine weight ≈machine rigidity is a principle that has not changed even with the advancement of technology.
Long tool life supported
by rigidity
By combining a highly rigid machine with a high-precision spindle, tool wear caused by vibration during machining, spindle runout, etc is minimized.
3 Stability
Thermal displacement control
for stability.
YASDA’s thermal distortion stabilizing system prevents sudden geometry change of the machine due to temperature change in the surrounding area by circulating the heat exchange liquid controlled at ±0.2°C relative to the room temperature throughout the machine.
This enables stable, high-precision machining for a long time.
4 Long life
YASDA‘s machines, which assemble straight parts together without stress, are resistant to geometry changes even after years of use, and achieve high-precision machining for a long time.
It is possible to continuously satisfy the ever-increasing precision requirements for products.
