We would like to introduce a case of regeneration and improvement of springs for machine tools (hooked tension springs) to a stainless steel pipe manufacturing company. We received a consultation from a customer who was troubled by the frequent breakage of tension springs in machines that had been in use for several decades, and they wanted to manufacture new ones without support from the machine manufacturer. In response, we reviewed the mounting mechanism and newly designed and manufactured springs with plate hooks and mounting brackets. We accommodated two types of machines, large and small. [Issues] <For large machines> ■ The hooks are prone to breaking, so they are secured with wire to loosen them. <For small machines> ■ The hooks are elongated. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of machine repair and improvement conducted by Naox Co., Ltd. At a tire specialty store, there was a request stating, "The constant load spring of the impact driver hoist that has been in use for 40 years has broken, and since the manufacturer's support has ended, I would like to repair it and continue using the old model that I am accustomed to, rather than switching to a new model. Additionally, the existing spring is too strong, so I would like to adjust it to a more suitable strength." In response, we investigated the actual machine and selected an appropriate spring. Along with this, we redesigned and manufactured the surrounding components to accommodate changes in installation dimensions, making the structure easier for maintenance work.

We would like to introduce a case study conducted by Naox Co., Ltd. A customer who owns a motorcycle manufactured 50 years ago expressed a desire to replace a broken spring in the front fork, stating that manufacturer support had ended and external parts were unavailable. They wanted to repair and continue using the motorcycle, which they are very attached to. In response, we investigated the actual machine, created drawings assuming a new condition, and manufactured two new springs. The uneven pitch springs we had on hand were deformed, but we reproduced them based on the original condition when they were new. Our company can create official dimension drawings from damaged or deformed parts and manufacture new ones, even without existing drawings. *For more details, please refer to the PDF materials or feel free to contact us.
