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.

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.

Advanced Milling 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.

Metrol High Precision Tool Height Sensor

The height sensor is installed in the machine on a non-movable stable bracket. It is produced by the well-known Japanese company Metrol and has very high resolution, IP67 waterproof and reliability.

The very sensitive sensor button allows you to measure the height of a milling bit with a very thin tip without breaking it. The measurement is given automatically by the machine NS – Motion Control program.

Ball Screws and Servo Motors

Our design utilizes ball screws and nuts to provide high-precision carriage movement over years of constant use. Combined with the Mira 6S’s servomotors, they make it possible to move the carriages with tremendous speed and force.

Workpiece Holders

The use of a collet gives you extensive possibilities for mounting various holders. You can clamp the cylindrical workpiece directly into the collet or utilize different adapters, chucks, and holders. Our team can also help you produce specialized chucks to suit your unique micro-milling needs.

Coolant System

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.

Coolant Proof

We’ve designed the Mira 8 and its rotary heads to provide reliable protection against coolant, moisture, chips, dust, and dirt throughout rigorous use. This is achieved by using a mechanical shaft seal. 

Nakanishi Ultra-Precise High-Speed Spindle

We’ve equipped Mira 6S with a high-speed ceramic bearing Nakanishi spindle NR-2351. The spindle is capable of rotating at speeds of up to 50,000 RPM, with a milling bit runout of no more than 1 micron. This spindle offers a multi-year lifespan with little to no maintenance or repair required.

Nakanishi spindles are a world leader in precision machine tools and are the only choice for serious machinists. The spindle has motor speed feedback, digital display controlling, and monitoring. The spindle housing is made from precision ground, hardened, stainless steel.

Mira – Bit

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.

Two-sided monitor position

The machine has the ability to place the monitor on the right or left side. Because it’s more convenient for the user.

You can also mount two monitors on both sides. Second monitor can be used for camera or digital microscope
