We use a jig borer made by Mitsui Seiki Kogyo for precision boring of spindle cases, bearing housings, and positioning dowel pin holes.
With a positioning accuracy of ±0.0015, precise positioning is performed to achieve micron-level accuracy in hole positioning.
In addition, the room temperature is controlled at 20°C±1°C - 58±5% humidity to ensure perfect conditions at all times.
It is a machine that can make other machines, processing high-precision parts by boring, milling, and facing.
