Precision machining【Capable of processing a wide variety of metals and complex shapes!】
Industrial sewing machine parts, automotive parts, hydraulic parts, construction machinery parts, pneumatic parts.
Leave it to us for turning, machining, grinding, and precision polishing!
Tochiden Co., Ltd. is capable of integrated processing from material procurement, turning, machining, heat treatment, polishing, to surface treatment. Our advanced processing technology, which allows us to machine complex shapes like crankshafts, an essential component of industrial sewing machines, from solid rods and achieve tolerances in the micron range through polishing, has been highly praised by our customers. Materials: Soft materials such as copper, aluminum, and brass, as well as high-hardness steels like tool steel, bearing steel, carbon steel, and chromium-molybdenum steel, and irregular materials such as forged and lost-wax castings. Lot size: Approximately 10 to 10,000 pieces (please consult us as it depends on the shape and processing). Size range: Φ4 to φ150, approximately L500, manageable by hand. *For more details, please request our materials or view the PDF data from the download section.

Company information
We handle everything in-house from cutting and grinding processes such as turning, machining, cylindrical grinding, centerless grinding, and internal grinding, to heat treatment, surface treatment, and assembly. We also accommodate material procurement for forging, lost wax, and more. Our integrated production allows us to meet customer needs with QCD (Quality, Cost, Delivery). We eliminate the hassle of managing costs, delivery times, and quality across multiple companies for our customers. Materials: SCM415, S45C, SCR415, MM45, A7075, A5042, C3771, etc. Iron, stainless steel, aluminum, copper, castings Shapes: From round bars to irregular shapes We design and provide processing jigs in-house. Lot sizes vary from about 10 to 10,000, so please consult with us. We specialize in mass production of lots ranging from 100 to 1,000. Sizes: Approximately Φ5 to φ150 mm, with larger items around L500 mm, we excel at palm-sized products. We accommodate strict geometric tolerances, such as 2-micron tolerances in cylindrical grinding. We can handle outside diameter and inside diameter grinding processes only, as well as turning and machining processes only. For eccentric shafts, spherical grinding, and precision machining, please leave it to us. We look forward to your inquiries!
