美国采购需求：4轴机械臂，轴机械臂，数控机械臂，协作机器人臂，协作机械臂，涂胶机械臂

We are looking for a suitable component for a lightweight application that will hold a microscope lens securely. The primary focus is on ensuring a strong, stable hold while maintaining a lightweight profile. Speed isn't a priority in our requirements, so we are more interested in durability and reliability under normal usage conditions. Could you provide us with some recommendations based on your available products? It would be helpful to understand the material options, weight specifications, and any customization possibilities you might offer. If you have similar previous projects or case studies, sharing those details would also be appreciated. Looking forward to your suggestions!
