Honing is a technique for polishing the inner surface of holes drilled with tools like drills to a shiny finish. It is possible to achieve a tolerance of ±2μm and a surface roughness of Ra0.02 or lower. This technique is utilized in rubber roller mold components for office automation equipment. Honing, which involves adjusting the tension of the grinding wheel and the rotation speed while referring to the drawings, requires skill to achieve precision. The high-precision finishing by our skilled workers supports various products. 【Supported Materials】 ■ Titanium ■ Inconel ■ Hastelloy ■ SUS304, 630, 316L *For more details, please refer to the PDF document or feel free to contact us.

"Gun drilling" is a technology for creating holes similar to those in rifles. It is capable of precision deep hole machining with hole diameters ranging from φ0.8 to 32.0, achieving a straightness deviation of less than 2μm. Using drills as tall as a person, we can create straight and deep holes. We are also skilled in deep hole machining of not only cylindrical shapes but also square objects. Drilling multiple holes on the end face can achieve high positional accuracy through NC control.
