井上鉄工所 List of Products and Services

At Inoue Iron Works, we provide measurement data files of tooth profiles, tooth shapes, and pitch measured by gear measuring machines, along with actual measurement data, according to our customers' requests. Gears are used under strict conditions for both precision and strength, so it is necessary to check whether they are finished according to the specifications in the drawings. Furthermore, to prepare for any unforeseen circumstances, we have established a system that allows us to confirm the heat treatment conditions at any time upon inquiry. 【Features】 ■ We deliver measurement data files and actual measurement data according to customer requests (all data related to ground gears is attached). ■ We have established a system that allows us to confirm heat treatment conditions at any time upon inquiry. *For more details, please refer to the PDF document or feel free to contact us.

To manufacture high-quality and high-precision gears, it is necessary to have a temperature-controlled room and machine tools capable of high-precision processing. Additionally, minimizing temperature fluctuations during the gear grinding process is crucial for improving product quality. At Inoue Iron Works, we have installed gear grinding and measuring equipment within a temperature-controlled room to enable high-precision gear processing and grinding. This allows us to produce gears with stable quality regardless of hot or cold days, or any season. 【Features】 - Installation of gear grinding and measuring equipment in a temperature-controlled room to enable high-precision gear processing and grinding. - Capability to produce gears with stable quality. *For more details, please refer to the PDF document or feel free to contact us.

At Inoue Iron Works, in order to achieve high-precision gear manufacturing, we operate two large-capacity air conditioning units continuously in the factory where gear grinding (gear finishing) is performed, creating a temperature-controlled room. In this temperature-controlled room, we have not only the gear grinding machines but also lubrication devices, tools, and measuring instruments used after gear grinding. By managing the environment at a constant temperature around 20°C, we create the conditions necessary for producing high-precision gears throughout the year. 【Features】 ■ Two large-capacity air conditioning units are continuously operated in the factory where gear grinding is performed. ■ Managed at a constant temperature around 20°C. ■ Creating an environment for producing high-precision gears throughout the year. *For more details, please refer to the PDF document or feel free to contact us.

At Inoue Iron Works, in addition to gear cutting and gear grinding, we also assemble gear units for industrial equipment that require reliability and durability, such as reducers, increasers, and indexing gear devices. The assembly of gear units requires not only high-precision gear manufacturing technology but also skilled assembly techniques. Therefore, our company handles high-precision gear units using high-precision ground gears. We also manufacture or procure various small parts necessary for the gear units in-house, and deliver them as finished units. 【Features】 ■ We handle high-precision gear units using high-precision ground gears. ■ We manufacture or procure various small parts necessary for the gear units in-house. ■ We deliver them as finished units. *For more details, please refer to the PDF materials or feel free to contact us.
