Founded in 1920. Our greatest strength lies in our one-stop production of large, high-precision parts, from arranging castings to machining, grinding, finishing with scraping, assembly, and precision assurance. This integrated system contributes to the optimization of quality, cost, and delivery time, as well as reducing the management workload for our customers. Leveraging the know-how gained from the structural components of semiconductor manufacturing equipment, we achieve large and high-precision machining that is difficult for other companies. Currently, we are looking to expand this technology into various fields.

At Fujita Manufacturing Co., Ltd., we are engaged in the precision machining of large items and the production of precision cast iron plates. In large precision machining, a stable environment is essential to minimize thermal deformation. We also accommodate large workpieces. For castings, we conduct thorough discussions with casting companies regarding the wooden patterns and structures, and we obtain them after annealing. Subsequently, we perform natural seasoning to eliminate internal stresses in the castings. 【Facilities (excerpt)】 ■ Constant temperature and humidity precision finishing inspection factory (±1℃) - 5 buildings ■ Constant temperature and humidity machine factory - 3 buildings ■ Thermo-clean chamber (±0.1℃) - 1 room ■ Constant temperature and humidity precision machining finishing inspection factory (±2℃) - 1 building *For more details, please download the PDF or feel free to contact us.

The "Auto Cross DG40AX" is an automatic drill grinding machine that can quickly process edge relief grinding and cross thinning grinding in one setup. Since grinding is done with a Borazon grinding wheel and grinding oil, there is no burning of the cutting edge, resulting in a clean grind that lasts longer. Additionally, it can be sharpened accurately with minimal grinding allowance, which reduces drill wear and saves on tool costs. 【Features】 ■ Drills last longer ■ Savings on tool costs ■ Savings on labor costs ■ No need for experienced workers; anyone can be a craftsman ■ Top-quality straight drills *For more details, please download the PDF or feel free to contact us.
