5-Axis CNC Mill Mira 6S

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.

Machine Resolution

0.3 Microns = 0.0003 mm

Mira 6S is a high-precision machine having a resolution of less than a micron. This gives it the opportunity to mill jewelry molds with the smallest details and achieve a completely glossy surface of the model.

Advanced Milling Technology

By purchasing a Mira 6S you become the owner of the most advanced CNC technology

All 5-axis machines in the Mira series are equipped with advanced milling technology. It is based on the latest system of simultaneous rotary table control, called “Smart Angular Movements Control”.

This significantly reduces the milling time and allows the machine to work more effectively.

JewelryCAM

5-Axis JewelryCAM (JCAM) is provided for each Mira 6 mill. JCAM is a unique program for calculating and preparing files for milling on a machine. It is created for jewelry design of any complexity and allows you to make the most intricate jewelry with the microscopic details.

NEW GENERATION OF 5-AXIS SIMULTANEOUS CAM PROGRAM

Mira Bit

PREMIUM CUTTING TOOL THAT CAN WORK NON-STOP FOR A WHOLE YEAR

The special geometry and shape of the Mira-Bit provide the opportunity to cut the wax to a depth of 25 mm in one pass. Because the Mira-Bit is manufactured from solid carbide, our high-volume clients are reporting up to 1-year average lifespan when milling modeling wax of all types.

Coolant Proof

The machine is reliably protected from coolant,  chips, and dust

The rotary head B in the machine has complete protection of the mechanism from the penetration of water and humidity inside. It took the company many years of research, trial and testing to achieve this.

Coolant System

The coolant system is a necessary part of all professional CNC machines

We’ve equipped this machine with a self-filtering Coolant system, which uses a pulsating supply that’s completely controllable from its touch screen. The coolant itself is a concentrated water-soluble oil diluted in plain water. It efficiently cools the milling area and improves the surface quality while preventing the spread of dust in your room.

Why MIRA Mill?

NS CNC MIRA IS NOT JUST A MACHINE

it is a complete system that can 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.

 

Rotary

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.

NS-MC

NS – Motion

5 – Axis Control Program made by NS CNC specifically to run Mira – X milling machines. It’s part of the NS – motion servo system.

NS-Holder

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.

Rhino

Rhino3D – 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

JCAM

JewelryCAM

Fully automatic 5 – axis CAM program for jewelry. It was created for ordinary users who do not have sufficient expertise in CNC.

Bit

Mira -Bit

A unique milling bit with special cutting geometry for wax milling to a depth of 25mm without roughing. It is made of solid carbide.
