In this project, RPS customized ultra-precision CNC micromachined parts—watch buttons—for a high-end watch manufacturer. Although these buttons are extremely small in size, they impose extremely strict requirements on precision, surface finish, and aesthetics. They are not only the core control components of the watch but also key details that reflect the brand’s craftsmanship and quality. The customer required these parts to achieve a perfect balance between functionality and aesthetics.
Leveraging our top-tier technology and extensive experience in the field of micromachining, we provided the customer with a comprehensive solution ranging from material selection to ultra-precision CNC machining and multi-step surface treatment, ensuring each tiny part is as perfect as a work of art.
Manufacturing Challenges & RPS Solutions
Material Selection & Micro-Structure
- Challenge: The parts are extremely small in size, requiring the realization of fine micron-level features while ensuring strength.
- Solution: We selected 6061 aluminum alloy as the material. 6061 aluminum alloy not only has good strength and corrosion resistance but also its excellent cutting performance makes it an ideal choice for micromachining. By using professional micro-tools and high-precision CNC equipment, we can easily achieve precise machining of all micro-features on the parts.
Ultra-Precision CNC Micromachining & Multi-Process
- Challenge: The parts include tiny threads, complex geometric contours, and fine surface details. For example, the head and base of the button need to fit perfectly, and the thread part requires strict precision control to ensure smooth screwing.
- Solution: RPS utilized ultra-high-precision CNC machining centers and fixtures specifically designed for micromachining. On the premise of ensuring part stability, we completed the machining of all complex features. We used micro-tools with a diameter of less than 1mm, and through precise programming and control, achieved accurate cutting of threads and perfect milling of surface curves. All parts underwent strict dimensional inspection, ensuring tolerances were controlled within 0.005mm, even reaching the micron level.
Multi-Surface Treatment & Aesthetic Requirements
- Challenge: The customer required surface effects with different colors and gloss levels to meet the design needs of different watch models.
- Solution: We provided a variety of surface treatment solutions, including anodizing and electroplating. For black buttons, we adopted hard anodizing, which not only provides a professional matte appearance but also enhances wear resistance. For gold and silver buttons, we used precision electroplating technology, forming a hard, high-gloss metal coating on the surface of the CNC-machined parts—endowing the product with a luxurious and exquisite appearance.
Outcomes & Value
Through RPS’s ultra-precision CNC micromachining services, we successfully manufactured these high-performance watch buttons for the customer. With their unparalleled dimensional accuracy, fine machining quality, and excellent aesthetic effects, these parts perfectly met all technical and design requirements for high-end watch manufacturing and received high praise from the customer.
This project once again demonstrates RPS’s top-tier capabilities in micro-part machining and complex metal manufacturing. We can not only transform the most challenging design drawings into high-quality physical products but also bring significant performance improvements and brand value to the customer’s end products through professional material and process selection.
