Even if the installation accuracy deteriorates, it can be restored to its original precision by making level adjustments.
The material of the bed, which is the foundation of the machine, was mainly made of cast iron because it allows for the creation of complex shapes. The cast iron structure can restore its original precision through leveling adjustments, even if the installation accuracy deteriorates due to changes in the floor or aging. The efforts and struggles of our predecessors are evident in the design that takes advantage of the properties of cast iron, making it easy to process, able to withstand weight, and resilient to changes. It is said that cast iron, especially when aged or seasoned, undergoes less change. Conversely, it is not an exaggeration to say that older machines hold more value. By maintaining a sturdy bed foundation and retrofitting it with modern control devices, the precision of the modified machines is truly remarkable.
