Doi Precision Co., Ltd.

Wide-ranging support for short delivery times on custom machining from medium to large workpieces to light cutting.

We handle large-scale machining of various metals, accommodating large cutting from within. Not only do we offer cutting services, but we also provide one-stop solutions for welding and assembly. We are involved in the processing of hot stamping molds and excel in machining tough hot work tool steels. Our machining work covers a wide range of materials, including not only iron but also stainless steel, aluminum, and castings such as FC and FCD. ■ High-precision machining of medium to large vertical and horizontal milling Using medium-sized vertical and horizontal milling machines, which are more cost-effective than gantry machines, we process long and large workpieces exceeding 1 meter. On our horizontal boring mill, we also perform cutting of cam components for cast press molds, utilizing a two-axis setup with an incline. ■ Wide range of capabilities for all metals, from thin sheets to heavy cutting We accommodate a broad spectrum of machining work, including not only iron but also stainless steel, aluminum, ceramics, and castings. ■ Ultra-short delivery times with comprehensive support including welding and assembly In addition to cutting, we also perform welding of medium to large fabricated products and TIG welding of aluminum materials. Furthermore, we provide one-stop solutions for heat treatment, surface treatment, welding, and assembly, supporting single-piece production, small lots, and ultra-short delivery orders.
