Honing process (precision finishing process)
Honing process made possible by years of deep hole machining technology.
We have developed a technology that enables honing processing of unprecedented small diameters and long lengths. Currently, our company is utilizing the technology cultivated through the development of gun drilling machines to create honing machines and honing tools that achieve extremely small diameters and processing lengths beyond existing capabilities. The target performance allows for honing of inner diameters from 1.0 to 10.0 mm and depths of 1,200 mm, making it possible to hone not only through holes but also blind holes, eccentric holes, and square bars. The development of this machine will enable improvements in the inner surface roughness of medical surgical tools and materials, as well as fine adjustments of deep hole inner diameter tolerances, all at lower costs than before, making it applicable in a wide range of fields.
basic information
Our company has the strength of owning in-house manufactured gun drill machines and processing technology that achieve top-class processing precision (straightness, roundness, surface roughness) in the industry, allowing us to provide low-cost, high-quality honing processing based on high-precision pilot holes.
