Latest Patents
Ohta’s notable patent pertains to a spindle unit designed to offset any displacement of the spindle caused by thermal expansion. This innovative spindle unit integrates a high-rigidity elastic member and a pressure chamber connected to an oil pressure control valve. An advanced displacement sensor and a tachometer are employed to monitor the spindle's speed, allowing the system to adjust the preload on the bearings accordingly. As the spindle's revolving speed increases, oil pressure enters the pressure chamber, thereby reducing the preload and allowing the spindle to move axially to counteract displacement caused by thermal expansion. This cutting-edge technology is pivotal in enhancing the performance and durability of spindle units.
