岩井工機 Product Lineup

At Iwai Koki, we handle the machining of various parts used in turbine and compressor applications. Focusing on lathe and machining processes, we can flexibly respond to projects that often have limited options, such as large parts, large-diameter workpieces, flange-type components, repair parts, and replacement parts. Whether it's single items or small lots, we can manufacture based on drawings and are open to consultations from the stage of considering processing methods and processes. We have a system suitable for projects that require quality, delivery time, and responsiveness, such as regular repairs, parts updates, and securing new outsourcing partners. 【For such concerns】 - Limited options for machining turbine and compressor parts - Looking for partner companies to request repair and replacement parts - Want to consult about machining parts like flanges and rings - Procurement risks exist with only existing outsourcing partners - Want to increase the number of machining partners for ongoing requests 【Usage scenarios】 - Updating existing parts - Regular repairs - Sudden replacement responses 【Benefits of implementation】 - Stable operation of equipment - Shortened delivery times - Cost reduction

This is a parts restoration service that solves serious troubles in equipment maintenance, such as "the manufacturer has gone out of business and spare parts are unavailable" and "there are no remaining drawings." At Iwai Koki, we provide comprehensive support from confirming the actual damaged item, measuring, creating drawings (reverse engineering), processing, to inspection, even if you only have the broken part on hand. We can consult on repair parts for large diameter round items, flanges, and rotating machinery starting from just one piece. 【Available Processes】 ■ Confirmation of the actual item, measurement, and estimation of worn areas: Even worn parts can have their original dimensions estimated by experts. ■ Creation of processing drawings: Digitizing drawings to facilitate smoother maintenance in the future. ■ Suggestions for materials and surface treatments: Consultation on strength improvements tailored to the usage environment is also possible. ■ High-quality processing and inspection: Manufacturing with reliable technical skills and thorough quality control. Furthermore, all drawings, materials, and inspection information from the initial production are carefully stored by us, allowing for quick and smooth responses to repeat orders from the second time onward. We are fully committed to meeting your requests to prevent sudden equipment stoppages and to prepare spare parts for the future. *For more details, please download the catalog or feel free to contact us.

In the power generation industry, turbines require high durability and precision. In particular, components used in high-temperature and high-pressure environments necessitate careful material selection and precise machining. The processing of special materials requires specialized technology and equipment. Our large lathe machining addresses these challenges and contributes to the maintenance of turbine performance. 【Application Scenes】 - Turbine blades - Turbine casings - Generator components 【Effects of Implementation】 - Increased turbine longevity through the supply of high-quality parts - Improved design flexibility by accommodating complex shapes - Enhanced power generation efficiency due to high precision

【1】We can accommodate small lots starting from one piece and respond to sudden short delivery times. We flexibly handle regular repairs as well as replacements due to unexpected troubles and requests for individual replacement parts, minimizing the risk of line stoppages. 【2】Extensive track record of parts for high-difficulty large and rotating machinery. We have numerous processing achievements for seal rings, sliding rings, diaphragm inner rings, retainers, control valves, impellers, labyrinth rings, spacer rings, bushes, sleeves, valve seats, impellers, rotors, and various flanges and covers. 【3】Contributing to stable operation of equipment and cost reduction with reliable technical skills. Utilizing lathe and machining processing technology, we achieve high precision even for large-diameter workpieces and specially shaped parts. We contribute to cost reduction and quality improvement by reviewing existing outsourcing partners and diversifying procurement risks. "If you have drawings but cannot find a company to undertake the processing" or "If you have concerns about existing procurement routes and would like to consult for a second opinion." If you have such requests, please feel free to consult with us.
