川島製作所 List of Products and Services

Our company is focusing on the processing of internal gears. We are capable of processing a wide range of items, not only those with large outer diameters but also those with small inner diameters and stepped gears. The new machine that started operation in September 2024 can process items with a maximum outer diameter of φ3,000 and a tooth width of 650mm, boasting one of the largest processing capacities for gear shapers in Japan. 【Features】 - Capable of processing a wide range of items, including those with large outer diameters, small inner diameters, and stepped gears. - Can process items with a maximum outer diameter of φ3,000 and a maximum tooth width of 650mm. *For more details, please download the PDF or feel free to contact us.

We are equipped with a Sunderland gear cutting machine. If the twist angle is 22°30', it is possible to process even without a keyway. We can process up to a maximum outer diameter of approximately φ2000, and for gear shafts, we have processing experience for shaft lengths of about 3.5m. *Shaft diameter has conditions. In addition to outer diameter processing, we also accept inner diameter keyway processing and spline processing. [Features] ■ Processing is possible without a keyway for outer diameters from φ40 to approximately φ2000 ■ Capable of handling long gear shafts exceeding 3m in length *For more details, please download the PDF or feel free to contact us.

We would like to introduce our high-precision gear grinding services. We can process up to a maximum outer diameter of φ3,000, and by exchanging the head, we can also process internal gears. We excel not only in large outer diameter items but also in long gear shafts and spline grinding, achieving precision that exceeds the old JIS Grade 0 even for large gears. The probe unit equipped on our machine guarantees the precision of the gears through in-process measurement. 【Features】 ■ Capable of processing up to a maximum outer diameter of φ3,000, and can process internal gears by exchanging the head ■ Proven track record of processing gear shafts longer than 5m ■ Can achieve precision that exceeds the old JIS Grade 0 even for large gears *For more details, please download the PDF or feel free to contact us.

We would like to introduce our specialty and strength in the machining of large gears. We can process up to a maximum outer diameter of φ6,000, and hob cutters can be mounted up to M40. By changing the head, we can also perform machining using end mills (M50 and above) and process internal gears. Additionally, we are equipped with large horizontal hobbing machines capable of processing shafts up to 6m in length, allowing us to handle large module pinion shafts and long splines as well. 【Features】 ■ Capable of processing up to a maximum outer diameter of φ6,000 ■ Can accommodate shaft lengths up to 6m ■ Wide range of capabilities including gear racks, large planetary frames, and eccentric structure gears *For more details, please download the PDF or feel free to contact us.

We would like to introduce the spline machining services we offer. We can process up to a maximum outer diameter of φ1,450 and a shaft length of 6m. We specialize not only in spline machining for long workpieces but also for spline machining on the end faces of large-diameter pinion shafts. We own a variety of spline cutters up to a maximum size of M10, and we also accommodate square splines. Additionally, we can perform spline machining on internal diameters and shafts that cannot be processed with a hob using a gear shaper, so please feel free to consult us if you have any machining concerns. 【Features】 ■ Capable of processing up to a maximum outer diameter of φ1,450 and a shaft length of 6m ■ Spline machining for large workpieces is possible with a gear shaper *For more details, please download the PDF or feel free to contact us.

We would like to introduce the gear cutting process for straight bevel gears provided by our company. We can process up to a maximum outer diameter of φ2300. Additionally, we can accommodate a wide range of modules from M2 to M30. We excel not only in processing large outer diameter workpieces but also in machining large module miter gears, and we can perform finishing processes using carbide tools. 【Features】 ■ Capable of handling a wide range from large outer diameters to large module workpieces ■ Finishing processes using carbide tools are also possible *For more details, please download the PDF or feel free to contact us.
