We have added a product page for shaft-type cylindrical grinding.

We accept cylindrical grinding of various metals. We have a track record of high-precision processing!

Have you been troubled by issues such as 'the surface of the workpiece became rough after quenching,' 'due to strict tolerances, machining with just a lathe is difficult,' or 'there are not many places that accept small lot orders'? In such cases, please leave it to Toyo Seiki Sangyo, which offers integrated production from lathe machining, machining, heat treatment, to grinding. We have 5 general-purpose cylindrical grinding machines and 6 NC cylindrical grinding machines, capable of handling small to medium lot sizes. Our machining range is from φ4 to 300, with lengths from 15mm to 700mm, and we have qualified personnel for first and second-class cylindrical grinding operations. Additionally, since we have our own heat treatment facility, how about combining heat treatment with your order? This can eliminate time loss due to logistics of the workpieces and compress delivery times and costs. We also have lathes and machining available, so we can handle all processes before and after heat treatment. Please contact us once. *For more details, please refer to the PDF document or feel free to reach out to us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

Are you making progress on measures for the "2024 Problem"? With stricter management of drivers' working hours, reducing "waiting time" has become an urgent issue in the logistics field. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability situation, reducing unnecessary waiting and queueing, and shortening waiting times to alleviate the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start addressing the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult with us.
