Machining for jewelers
Built off of years of experience perfecting 5-axis milling technology, this lean system combines some of the best technology NS CNC has to offer into one compact package. The Mira-6 was designed to meet the needs of the jewelry industry, so it has to be both easy to use and efficient. To accomplish this, it incorporates our newest control system and our “Smart Rotary Head” technology. NS CNC prides itself on attention to detail, and the Mira-6 is a natural extension of that pride. Watch as this masterpiece of machinery quickly and carefully carves out even the most ornate designs. Then, cast a piece from this mill, and find out that all that needs to be done is the polishing.

Why MIRA Mill ?
NS CNC Mira is not just a machine, it is a complete system that can simply and quickly make a model of jewelry from the most popular 3D-file formats. The ability to operate in 5 different axes enables the user to create complex models not found in previous machines. It is designed for jewelers who do not have special education in CNC machines and for those who do not have the time to calibrate and configure complicated settings in the machine.
NS – Motion
5 – Axis Control Program made by NS CNC specifically to run Mira – X milling machines. It’s part of NS – motion servo system.
JewelryCAM
Fully automatic 5 – axis CAM program for jewelry. It was created for ordinary users who do not have sufficient expertise in CNC.
Rhino 3D – Base
Jewelry CAM based on Rhino 3D or any related programs such as Matrix or RhinoGold. These are the most common types of 3D models and files in the market
Dual Rotary
The machine is equipped with a unique Dual Rotary Table, which allows the work-piece to rotate in two different axes while also remaining completely stable.
Mira -Bit
A unique milling bit with special cutting geometry for wax milling to a depth of 25 mm without roughing. It is made in solid carbide.
NS – Holders
The unique wax work-piece holders allow the A rotary axis to get even closer to the spindle head, allowing for more access to your model.
Advanced Milling Technology
All 5-axis machines series for Mira are equipped with advanced milling technology. It is based on the latest system of simultaneous “Smart angular movements control” of rotary tables.
This significantly reduces the time of milling and allows the machine to work more effectively.
Mira – Bit
This next generation of wax milling bit. The special geometry and shape of the bit give the opportunity to cut the wax to a depth of 25 mm in one pass. Manufactured from solid carbide, our high-volume clients are reporting up to 1 year average lifespan when milling modelling wax of all types.
High Precision Spindle
NSK Nakanishi spindles are installed on all NS CNC mills. They are a world leader in precision machine tools and are the only choice for serious jewelers. The spindle has a long service life and is very reliable. The standard milling machine receives a 30,000 RPM spindle, but for faster milling you can choose to upgrade to a 50-60,000 RPM model.
The spindle collet set has a standard diameter of 1/8″ (3.175 mm). If the another collet size is desired, we can insert a collet of any size from 1.0 mm to 6.5 mm in increments of 0.1 mm.
NS Motion Control
Coolant System
Keeping the cutter and working piece wet during operation greatly improves the surface quality of models. The coolant prevents the milling bit from overheating and prevents the dust produced from milling from spreading to your shop and any nearby equipment. The system automatically and continuously filters and circulates the coolant. Used coolant is collected from the collection tray beneath your work-piece and is recycled by draining back into the coolant reservoir. The coolant fluid contains a 5% – 15% emulsion of water-soluble oils.
