Precise engraving device.

The rock-solid engraving machine design guarantees highest precision during engraving or milling of your jewelry. Basic components accurate to the millimeter, the use of high-quality machine components and exact assembly result in a precision that leaves nothing to be desired. Precision made in Germany.

Powerful jewelry engraving machine.

Due to the innovative machine concept, our jewelry engraving machine achieves the highest stability and rigidity. Reduce your tool wear and get machining surfaces of the highest quality. Highly polished machining surfaces are achieved when engraving with the CNC milling machine, giving your jewelry and workpieces an incomparable value.

Unique.

The newly developed measuring system integrated into the engraving machine enables you to precisely measure your workpiece surfaces. The measurement data thus obtained is used to compensate for curved or uneven workpiece surfaces. This allows you to machine curved and three-dimensional jewelry surfaces despite simple 2D drawings. In addition, electronic compensation reduces tool wear and manual adjustment of engraving depths is a thing of the past.

Automated CNC engraving machine.

Thanks to the integrated tool changing system with a capacity of 12 tool stations, you can also process more complex applications automatically. Various machine cycles automatically set up the CNC engraving machine for your workpiece.

MACHINING TYPES OF THE ENGRAVING MACHINE

 

Round inside machining with the engraving machine for jewelry

Refine your jewelry or workpieces with high-quality deep engravings that are second to none. No matter if ring or bracelet. With the engraving unit of the CNC milling machine, you can process any piece of jewelry from the inside. The rotary axis of the engraving machine clamps and rotates the workpiece around its own axis. Specially designed interchangeable clamping jaws clamp your workpieces stably and with repeatable accuracy. The spring force of the scribe engraving unit can be precisely adjusted to the material to be engraved.

Round outside machining with the engraving machine

Outside engraving of round jewelry takes place with the milling spindle. Mill and engrave all imaginable patterns and fonts into the workpiece surfaces. The setup of the CNC engraving machine and scanning of the jewelry surface is done automatically before the actual milling. Rings, bracelets and writing instruments, for example, can be clamped and engraved on the rotary axis. A 4-jaw chuck is available for clamping oval jewelry, e.g. bangles. This allows more complex and oval workpieces to be clamped securely and with repeatable accuracy. You are welcome to ask us for clamping solutions specially adapted to your needs.

Flat machining with the engraving machine for jewelry

In addition to engraving round jewelry, the ENGRAVER 3 can also effortlessly handle flat workpieces. Flat workpieces, such as medallions, watches, bracelets or signs, are clamped into the engraving machine by means of a precision centering clamp. The clamping jaws can be turned and changed without tools by means of a click system. We can also offer you individual clamping jaws for your jewelry pieces.

MAIN FEATURES OF THE CNC ENGRAVING-MILLING-MACHINE

 
CNC engraving and milling machine with transparent machine housing

Transparent engraving machine housing

The safety concept of the engraving and milling machine consists of a transparent machine housing and an electrically driven lift door. This makes it very easy to load the engraving machine with your jewelry or workpieces from the front. Due to the highly transparent housing material, all parts of the CNC milling machine are optimally visible. Impress your customers with the innovative housing design of the ENGRAVER 3.

Automatic tool change with the CNC milling machine

The ENGRAVER 3 has an automatic tool change. With this, you can automatically insert and exchange your tools. Engrave or mill your jewelry with different tools without interruptions and fully automated. The tools are clamped pneumatically by means of a collet chuck. The tool magazine of the engraving machine includes 12 places and a receptacle for the measuring tip. A tool length sensor is integrated in the magazine to correct the different tool lengths. The tool magazine is located safely and separately in the rear interior of the CNC engraving machine.

Measuring system for height compensation of curved surfaces

The newly developed and fully integrated measuring system in the CNC milling machine is unique. Even curved jewelry surfaces can be measured with this system. The measurement data obtained is used to compensate for the height profile of the workpieces. Thus, even curved jewelry pieces (3D) can be engraved or milled optimally and quickly with simple and two-dimensional drawings. Gain an advantage over conventional engraving depth controllers, where the engraving depth must be set manually. In addition, you can reduce your tool wear enormously through the electronic height compensation. This is due to the use of optimum cutting data for your tools. The engraving depth no longer has to be achieved in a single cut.

Minimum quantity lubrication for cooling and lubrication of the tools

A fully integrated tool cooling and lubrication system is available for the CNC milling machine. This minimum quantity lubrication cools and lubricates the milling tools during machining by air and spray mist. Thus, significantly increase the tool life of your tools. In addition, the constant lubrication achieves a higher surface quality of your jewelry. The spray head of the lubrication system is completely integrated in the spindle block of the machine and does not have to be adjusted manually.
