CNC stone engraving machine. What is the difference between stone cutters for CNC machines and how to choose them

A stone milling machine is necessary for processing shaped and flat surfaces. Milling helps to make corners, grooves, images, chamfers; in addition, the process is used for processing the ends.

Stone work is carried out using special rotating cutters. Translational movements are performed by a table on which the workpiece is mounted. Only diamond cutters are used for stone processing.

Types of stone cutters

Diamond cutting elements are used for grinding surfaces. When working with stone, cutting should be wet; this technological feature will increase the service life of the cutter.

Cutting tools of this type are used for processing rocks of varying degrees of depravity and abrasiveness. For processing can be used:

• marble;
• artificial stones for finishing;
• granite.

Experts use diamond cutters for the following work:

• cutting;
• applying images, inscriptions;
• giving various necessary forms.

Classification of cutting tools

Cutting tools are divided into several types.

Burr cutters are coated with diamond powder and are used for roughing hard rocks and shaping relief.

Polycrystalline diamond PCD. Used for finishing small 3D reliefs. Additionally, the cutter helps to engrave on granite and other workpieces. This tool can last a very long time if it is not subjected to strong vibrations and heavy mechanical stress.

An end mill is designed for processing the end.

Profile cutters carry out profile work on stone.

Diamond cutters are distinguished by the most accurate work; they do not leave chips or defects. But caring for cutting tools should be especially meticulous.

Machine characteristics

A CNC stone milling machine is a piece of equipment controlled by . This makes it easier for people to work and makes productivity and quality indicators several times higher. Sometimes electronic devices achieve such precision of operation that is impossible with human participation.

A milling machine is capable of performing some operations. The workpiece is mounted on and the stone is processed using translational, rotating movements.

A cantilever CNC machine for stone processes a workpiece using a console, the stone is attached to it, and it produces movements that help to process hard rocks. The spindle is rigidly adjustable and stationary. Consoleless equipment operates due to the movement of the work table or the spindle itself.

The structure consists of the following elements:

• vertical, longitudinal and transverse guides;
• Desktop;
• Column;
• base;

The CNC machine for stone performs all operations automatically using special information, which is recorded on electronic media. Control programs can be of different types.

Equipment advantages

The CNC unit has the following advantages:

• Hardware with software increases productivity several times.
• High precision manufacturing of parts.
• Elimination of defects and chips.
• Improving the quality of processing.
• Reducing dependence on manual labor, this feature allows you to save on personnel.
• Reducing time to produce a part.
• Processing of the workpiece is 2–3 times faster.

Application area

Stone milling machine is used:

• For the manufacture of monuments and various ritual products.
• The unit is capable of producing three-dimensional modeling, applying beautiful, fine engravings, and producing artistic compositions.
• For the production of interior decorations.
• Platbands for windows, doors.
• Cutting artificial stone for external and internal finishing works.
• Production of souvenirs.

Stone processing process

Stone has been used for a long time in construction, decoration, interior decoration, and funeral services. It is valued for its endurance, hardness, long service life and attractive external qualities.

The hardness of the stone is the main problem in processing. Previously, this process took a lot of time and required special efforts. Today, the procedure has been facilitated by special machines with automated operation. They are able to take into account the fragility, brittleness and complexity of the material.

Milling stone on a special machine differs from processing materials such as plastic, wood, and metal.

To work with hard rocks, durable, reliable diamond-coated cutting tools are used. Experts recommend using coolant during work; it helps the tool not to become dull too quickly.

Peculiarities

The stone has an impressive weight, it is best to cover the work table with protective elements; they must not be pressed through, therefore they are characterized by high wear resistance. The workpiece must be securely fastened, the cutting force of hard material is high and this can lead to movement of the stone.

Blanks and diamond cutters are expensive, so processing must be of the highest quality, waste-free and effective. The numerical setting must be set to the correct mode to avoid damage. Software equipment requires a scrupulous attitude from the master. Almost all stone parts are large in size, which requires a lot of working time.

During the milling process, crumbs and dust are released abundantly. Therefore, the premises must be selected according to certain parameters. It is best not to use a personal computer to control machines. Excessive dust will quickly damage the equipment. It is best to use special remotes and controllers. Controlling such units using a PC is unprofitable.

A CNC stone milling machine, especially one with a large working surface, a powerful spindle and additional controls, is quite expensive.

Due to the hardness of the stone, it is necessary to mill it at a lower cutter feed than for more pliable materials

• Roughing occurs using a face tool with an inclined plunge.
• Finishing is carried out with a conical cutting element.
• With the help of diamond cutters, the speed can be maximized, but in this case it is necessary to use a coolant system.

The quality of processing depends on the vibration of the machine and the rigidity of the system itself. Modern equipment most often meets these rules. Experts advise using high-quality cutting tools and always securing the workpiece securely.

How to choose the right one

In order not to make a mistake when choosing equipment for milling, you need to take into account some criteria.

Clarify the parameters of a large workpiece - this will help to properly set up the work table so that it is easy to process a large stone in one installation.

The design of the machine, in the best case, should be monolithic, cast iron, but modern manufacturers reduce the cost of equipment by using aluminum for some elements.

The electric spindle plays an important role in the operation of the machine. In this case, it is better to trust famous manufacturers who have managed to establish themselves positively. A high-quality spindle should last at least five years.

It is necessary to choose machines with semi-automatic tool change.

It is better to choose a control rack from Syntec; it has many advantages and does not require connection to a PC.

The software most often supplied with the machines is outdated, so it is better to reinstall it on the Russified ARtCam.

The equipment should be well maintained, this will reduce repair costs and make it easier to find spare parts.

A CNC stone milling machine is often used in large-scale enterprises for industrial purposes, funeral services, and the production of finishing materials.

The stone milling and engraving machine remains the prerogative of small private workshops and factories; it is easy to use, less demanding, and has high-quality materials in its construction.

These industrial CNC stone milling machines (stone cutters) are designed for 2D-5D processing of marble, granite, any type of stone, glass, mirrors, wood, plastics and metal. An industrial CNC stone milling machine of the stone cutter series allows you to produce artistic panels for finishing the interiors and facades of buildings, company logos, advertising products, large-sized monuments, sculptures, stone columns. Processing stone with a CNC machine is faster, more accurate and cheaper than processing by hand.

When processing stone or metal on an industrial CNC milling stone cutter, it is possible to supply coolant to the cutting zone. In addition to artistic use, these industrial CNC stone milling machines are well suited for shaped and conventional cutting of tiles, any stone, limestone, synthetic marble and any other hard materials.

In terms of rigidity and power, they are the most universal CNC machines for stone processing. Industrial CNC milling machines for stone (stone cutters) can process both hard abrasive materials (glass, stone of any hardness) and metals and soft materials (wood, plastics, polystyrene foam, polystyrene foam).

Industrial CNC milling stone cutters can be used in various industries, businesses and hobbies. For example: the production of monuments, fireplaces, paintings, souvenirs, sculptures, the production of prototypes of any goods or forms, the production of models for foundries, the production of advertising, models of architectural structures and other products made of stone and other materials of high hardness.

Our achievements

Heavy-duty welded thick steel CNC stone cutter body

The body of this industrial stone CNC milling center of the “Stone Cutter” series is made of welded steel parts. Steel thickness - up to 15mm! The design of the CNC stone cutter makes it possible to achieve high rigidity of the CNC machine, despite its impressive size. Thanks to this, the industrial CNC stone milling machine is resistant to static and dynamic loads, as well as vibration. Thanks to this, CNC machines from the Twitte plant are distinguished by high processing accuracy.

Specialists strive to process high-precision sites for installing guides. High precision is achieved by milling the sites on our CNC machines.

The presence of these features allows us to achieve high precision in the operation of our industrial CNC milling machines for stone.

Powerful steel portal of an industrial CNC stone cutter

On large production machines Kamensk machine tool plant "Twitte" a powerful portal with a rigid steel structure is installed. Just like the frame of an industrial CNC stone cutter, the portal is made of thick sheet steel.

Used in CNC machines Twitte The portal design allows for resistance to dynamic and static loads. Due to the design of the portal used in the machines of the Twitte plant, vibration does not have a negative impact on the processing of products.

These features allow industrial CNC milling machining centers for stone of the “Stone cutter” series from the Kamensk Twitte plant to process materials of increased hardness, including steel and various particularly hard types of stone.

High-precision rail guides for large-scale CNC machines

On large CNC machines Kamensky Machine Tool Plant Rail guides are installed, and a gear drive is also used here. Rail guides provide greater rigidity compared to round guides, which allows processing on this machining center stone and steel. Rail guides minimize vibration and make the stone processing center more resistant to static and dynamic loads.

Rail guides are also less maintenance intensive than round guides. Due to these factors, the service life of our CNC machining center increases significantly.

High precision ball screws

The Kamensk plant “Twitte” installs high-precision ball screws along the Z axis on its stone processing centers. By installing this element of the machine, backlash in their operation is eliminated.

Together with other structural elements, high-precision ball screws provide colossal CNC precision to stone centers in the processing of products.

Fifth coordinate for processing complex volumetric figures

On CNC machining centers for Kamen of the Kamensk Machine Tool Plant, a rotating head (5th coordinate) is installed. Thanks to this, the spindle can rotate in vertical and horizontal planes.

The rotating head allows complex milling operations that cannot be performed in 3- or 4-axis machining, such as various grinding operations.

The presence of a rotating head makes it possible to produce three-dimensional figures of any complexity on such processing centers: statues, figurines, three-dimensional logos, etc.

The machine is equipped with a professional numerical control rack, inside which a control unit is also installed. The control program is loaded into the rack using USB drives; the rack allows you to edit, start and stop the program.

The CNC rack is a more professional solution compared to a conventional personal computer, which can also be used to control the machine. Unlike a PC, the rack works noticeably faster, since there is no need to waste time loading the operating system, and also waste processor resources on running the OS. The CNC rack loads almost instantly.

Another big advantage of the CNC rack is its resistance to computer viruses, since it does not use Windows OS, which is very susceptible to viruses.

Servo motors are installed on all machine axes

All machines in this series already have servo motors installed as standard. Their main advantage compared to stepper motors is the presence of feedback (resistance to errors).

The principle of operation of motors of this type is such that they monitor the correspondence of the actual movement to that which should occur according to the program. Accordingly, if for some reason the actual movement does not correspond to that contained in the program, this means that some kind of error has occurred and further processing will not proceed correctly. In this case, the servo motor will stop processing, unlike a stepper motor, which can break the cutter and ruin the workpiece.

Flexible cable channel

On CNC machining centers for stone produced by the Kamensky Machine Tool Plant Twitte, flexible cable channels (cable layers) are installed so that the cable system used on the machines is correctly laid when moving the moving parts of the machine, does not get tangled and does not interfere with the operation of the machine itself.

Our plant uses cable channels from the world's leading manufacturers, time-tested. They are made from glass-filled polyamide, which makes them flexible and durable at the same time, as well as impact and oil resistant. Cable layers have good dielectric properties.

Engraving machines are used to apply designs, patterns and textures to the surface of natural granite and other types of stone. Such equipment is widely used in the production of monuments, paperweights and artistic decorations.

From this article you will learn what a stone engraving machine is. We will look at its design and principle of operation, and also provide recommendations for choosing such equipment.

1 Capabilities and purpose of engraving machines

The work of engraving machines was previously performed by master masons, who applied designs to the surface of the stone using a hammer and carving tools. Industrial development has led to the emergence of CNC engraving machines - equipment capable of operating in a fully automatic mode.

The machine operator only needs to load into the machine’s memory the image that needs to be applied to the stone, on the basis of which the CNC (computer numerical control) will create an action algorithm and begin the work process. The use of CNC engravers provides the following operational advantages:

• the ability to apply images of any complexity and size;
• cardinal acceleration of the process of obtaining finished products;
• minimal risk of defects in the finished drawing;
• effective work with all types of surfaces - from marble to granite and other stone-like materials;
• long service life of the equipment and no need for regular maintenance.

A stone engraving machine is quite highly specialized equipment. Such units are indispensable in the production of monuments, bas-reliefs, elite finishing materials and prefabricated building structures (parts of fireplaces, tiles, etc.).

1.1 Design and principle of operation

The main working unit of an engraving machine is a needle with a diamond tip, which forms the required image on the surface of the stone. The unit itself consists of a frame made of aluminum profiles that serve as a supporting frame, and axes fixed on them along which the carriage holding the needle moves.

Two electric drives are responsible for moving the carriage, one of which imparts movement to the stone workpiece, the second to the diamond needle. The power of the engines depends on the class and functional purpose of the machine; in small-sized units it does not exceed 3-5 kW.

A modern engraving machine has the ability to operate in automatic mode thanks to the presence of numerical program control. The CNC controls both the movement of the workpiece and the stroke of the needle. The needle itself is a consumable item; it has a limited service life due to wear and tear during operation. On average, a diamond needle is enough to engrave 50 images up to 40*50 cm in size, after which it needs to be changed or reprinted.

Let's consider the sequence of actions by which a CNC engraver works. Initially, the operator enters an image into the CNC block that needs to be reprinted onto the stone, according to which the automation creates a work algorithm. Next, the data remaining from the previously implemented program is reset - the coordinate axes along which the carriage with the laser needle moves are reset.

At the next stage, the machine sets the needle to its original position, from which it begins to move. If a textured image is applied, engraving is carried out in several stages, at each of which a separate part of the picture’s relief is created - from large details to small ones. If the design is single-layer, without texture, engraving is done in one go.

2 Laser and impact engravers - what's the difference?

CNC engraving machines are divided into two types - laser and impact. The differences between them lie in the type of actuator; the design in impact machines is applied using an abrasive-mechanical method, while laser units carry out non-contact engraving, as if burning an image onto the surface of the stone.

The advantages of laser engravers are:

• high speed of operation, which is especially important in mass production conditions;
• non-contact engraving is of higher quality, since there is no risk of defects in the image due to the use of poor diamond needles;
• images and patterns applied using the laser method are distinguished by better detail and realism;
• no need to replace consumables, which reduces equipment operating costs.

However, the key advantage of a CNC laser engraver is its versatility. Such machines can process not only stones, but also other types of materials, including glass, wood and plastic. Laser machines also have a number of disadvantages, namely their high cost due to a more complex design and low engraving depth, which does not allow them to form relief images.

2.1 Stone engraver at work (video)

When choosing a CNC engraving machine, first decide on its working area. This concept means the maximum area of ​​the image applied by the installation; in the middle price category, the most common are engravers designed for an area of ​​30*40, 50*60 and 60*120 cm. If you need a machine for the production of monuments, you need to take equipment with a working area of ​​50*60 cm.

If your budget allows, then it is best to take a laser engraver. In this case, you will benefit both in print quality (laser equipment can produce images with a resolution of up to 1000 DPi) and in production volumes, since engraving speeds can reach up to 10 mm/s. The laser tube in such a machine needs to be changed no more than once every 3 years, while the needle must be replaced every 10 images.

Regarding the cost of engraving. Drawing an image of 30*20 cm (portrait) using a percussion machine costs about 50 rubles, taking into account depreciation and replacement of the needle, while the cost of a similar pattern on a laser machine does not exceed 15-20 rubles.

Among the trusted manufacturers of this equipment, we highlight the following companies:

• Sauno (America);
• Mirtels (Germany);
• Utekhin (Russia).

The world's leading manufacturer of engraving equipment is Sauno, founded in 1992. This brand supplies the market with both impact and industrial-grade laser engravers. The optimal option for an impact machine would be the Sauno Graphic 3-K model, which is available in three variations with a working area of ​​60*76, 60*120 and 80*190 cm (the latter option is suitable for engraving monuments). The engraving depth in Sauno 3-K varies between 0.1-0.5 mm; the machine creates an image measuring 30*40 mm in 15 minutes.

The company's product range includes only one laser engraving machine - the Sauno ZKL engraver. This model is capable of working with materials such as stone, wood, glass and plastic, while the applied images have photographic accuracy. The dimensions of the working field in Sauno ZKL vary from 55*90 to 75*155 cm.

As an alternative to Sauno laser engravers, you can consider Mirtels machines, which cost 10-15% less. We recommend paying attention to the following models:

• Mirtels L5060 - working area 50*60 cm;
• Mirtels L60120 - working area 60*120 cm;
• Mirtels L90170 - working area 90*170 cm.

The best choice in the segment of inexpensive equipment would be the Utekhin EXPERT-GK engraver. This machine is capable of working exclusively with granite and basalt; it cannot be used for marble and various types of plastic. Utekhin EXPERT-GK has a working field with an area of ​​60*100 cm, the working depth is limited at 0.3 mm. A portrait measuring 30*20 cm is applied by the Utekhin EXPERT-GK machine in 1-2 hours - this is extremely slow in comparison with analogues, but is acceptable due to the minimum cost of this engraver (140 thousand rubles).

The unit is equipped with a 50 W electric motor operating from a 220 W household power supply. Also, the machine can operate in low-power mode consuming 10-12 V, which allows you to finish engraving during a power outage by powering the machine from a regular car battery.

This model has compact dimensions of 135*92*200 cm and a light weight of 20 kg; it can be mounted on a tabletop. The manufacturer provides a 1-year warranty for Utekhin EXPERT-GK, while the Utekhin company supports previously released equipment with new software that expands the functionality of older models.
