Remarkable development of industries in recent times demands further higher precision parts everyday.
Extremely strict and severe standards are implemented in the United States, a leading country with various modern industries such as space development and aircraft industries which require precision and state-of-the-art technologies.
YASDA has implemented these high level American standards that YASDA is able to provide our customers with ultra-precision granite level blocks whose accuracy meets the American grade AA standard which is far more stringent than JIS grade 0.

The level block is extremely important for every measurement as its degree of reliability determines the accuracy of high precision parts. As time passes, the accuracy of granite level blocks becomes more important than ever.
YASDA offers our customers the services to inspect, modify, and correct the granite level blocks which are being used currently. We hope our techniques will assist you in manufacturing highly reliable and precise products which are currently in demand.
When compared with cast-iron level blocks, people might have unfavorable ideas such as "High price" and "High correction and modification costs" on granite level blocks; such misperceptions prevent the granite level blocks from being widely used by manufacturing industries. In fact, the granite level blocks cause extremely little strain and few variations over time, therefore, the modification and correction by engineers with sufficient and excellent skills are easier than those of cast-iron level blocks.
At the same time, there is extremely little strain resulting from rust and temperature so remarkable sliding performance can be maintained. This is one of the great advantages of granite level blocks over cast-iron level blocks. All these aforementioned advantages prove that granite level blocks are more useful, economical, and reliable than cast-iron level blocks.
