The jewelry manufacturing industry is undergoing a technological transformation with the introduction of the Mira 6S five-axis precision milling machine by NS CNC. This compact system represents a significant advancement in jewelry mold production, combining cutting-edge technology with specialized design to address key challenges in the field.
Micron-Level Precision for Exquisite Details
The Mira 6S boasts an impressive mechanical resolution of 0.3 microns (0.0003 mm), enabling it to achieve precision beyond human visual perception. This capability allows for the creation of intricate textures, complex hollow structures, and flawless surface finishes in jewelry molds. The system's exceptional accuracy significantly reduces the need for post-processing while ensuring faithful reproduction of even the most delicate design elements.
Smart Rotary Head Technology
At the core of the Mira 6S's innovation is its Smart Rotary Head technology, featuring the proprietary Smart Angular Movements Control system. This technology enables synchronized control of the rotary table, dramatically improving processing times and operational efficiency. The system's ability to handle complex curves and multi-angle machining with unprecedented fluidity makes it particularly valuable for intricate jewelry designs.
Specialized Software for Jewelry Production
Complementing the Mira 6S's hardware capabilities is the JewelryCAM (JCAM) software, specifically developed for jewelry design and file preparation. This comprehensive CAM solution can process designs of any complexity and generate machining paths that accurately reproduce microscopic details, ensuring design integrity throughout the manufacturing process.
Durable Cutting Tools for Extended Use
The Mira 6S utilizes the Mira-Bit cutting tool, featuring a unique geometric design that enables single-pass wax cutting up to 25 mm in depth without requiring layered rough machining. Constructed from solid carbide, these tools maintain optimal performance for approximately one year under typical production conditions, offering both cost efficiency and processing consistency.
Robust Construction for Demanding Environments
The machine incorporates advanced sealing technology in its B-axis rotary head, providing reliable protection against cutting fluids, chips, and dust. The self-filtering coolant system, controllable via touchscreen, uses a water-soluble concentrate that effectively cools the machining area while minimizing dust dispersion, creating a cleaner working environment.
