Latest Patents

Masaru Kuroiwa's latest innovations include a sophisticated numerical controller designed for drilling machines. This novel controller enables a drilling machine to perform a feed operation while the spindle rotates. It suspends the feed operation for a predetermined dwell time at a specific hole bottom position, subsequently allowing for drilling through spindle retraction. The controller adeptly calculates the dwell time based on a specified rotation amount to enhance precision.

Another noteworthy patent focuses on controlling the acceleration and deceleration of the spindle feed rate. This numerical controller improves drilling efficiency by decelerating the spindle feed rate during the bite portion to achieve a velocity lower than the commanded feed rate. Once the drilling passes through a designated velocity recovery point—where spindle load is stabilized—the controller accelerates the spindle feed rate back to the commanded level, ensuring optimal performance.
