5-Axis CNC Mill Mira – 6
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.
Milling VS Printed
NS CNC is inspiring jewelry creators everywhere with its advanced detailing capabilities. See why customers are falling in love with milling all over again. Read more
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
Control of the machine is carried out by the NS Motion program within the built-in computer. This program is designed specifically for the MIRA Mill machine family, and is both reliable and easy to use. It is loaded automatically when you turn on the machine and requires no additional settings. As well as moving the carriages and rotary tables, the system controls the spindle, coolant system and various sensors. Its optional wireless communication settings allows the user to connect to the internet, enabling use of support software such as Skype and Team Viewer in case troubleshooting is required.
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.

Unpacking the Box
Each machine is delivered to the customer in a very strong wooden crate, which prevents the machine from being damaged during transportation. Inside the crate, the machine is secured to a spring base, which smooths shaking and vibrations.
When unpacking the crate, the customer should carefully follow the instructions glued to the side of the crate and unpack the machine step by step. Failure to follow the unpacking instructions can result in damage to the machine. To unpack the machine, you will need a screwdriver with a Robertson head, also known as a Square or Red, head #2.
Together with the machine, we send you all the necessary accessories and consumables that you will need to immediately start working on the machine. If you need more consumables, then you can order them on our Shop page or you can buy them from your local supplier.
NS – Account
Each user of our machine and/or CAM program gets access to an NS CNC User Account (a so-called “NS-Account”). When logging into his or her NS-Account, the user gets access to a server where various files with manuals, lessons, installers, test programs and many other things that are needed to work on the machine are stored. This is especially true for novice users. To use these files, you must first download them to your computer. If you have forgotten your username and password to log into your account, you can restore it automatically, or you can contact our technical support team at NS CNC for help.
