Mini milling machines that are provided program controlled(CNC) are widely popular among manufacturers involved in the production of certain components for various mechanisms and certain components installed on vehicles.

CNC milling machines. Tabletop and small-sized.

Even in the recent past, on small-sized machines, all processing of metal parts was done manually. A little later, machines appeared, where most of the operations were already performed automatically. But nowadays, mini-machines equipped with program control have become increasingly common and automatically perform almost all metal processing work.

The workpiece is rigidly fixed on the deck of the machine's work table, then a certain program is entered, after which the machine performs almost all milling operations, maintaining all the specified parameters for processing parts.

Milling machines that process metal products are produced in two types:

• With console
• Not having a console.

The most popular of them are console machines. The convenience of using such a machine lies in the location of the workpiece being processed, which is rigidly fixed on the console, and all operations to move it along the cutter are performed by the console. In this case, the spindle with the attached cutter remains motionless.

On machines that do not have a console, the workpiece is attached to a work table, which can move both along the machine and across it. In this case, the cutter is also in motion along the horizontal or vertical axis.

Certain information is pre-entered into the machine’s memory, according to which the program control performs almost everything technological processes for milling workpieces. To carry out certain metal milling operations, especially for such small-sized machines, several software programs have been developed.

Providing local type.

Intended for a group of machines performing drilling and boring operations. In this case, only certain coordinate points that must be processed are entered into the machine’s program memory.

Providing contour type.

Used for milling and grinding machines. Information about the trajectory of the cutter when processing a part is stored in memory.

Providing a combined type.

This software is used in multi-tasking machines, which are of the turning-milling type. This software combines the programs of the two previous types of software.

Providing multi-circuit type.

This software is a rather complex program control, as it can perform almost all the processing functions of metal parts that are inherent in small-sized milling machines. This CNC program is used to control machines that belong to the wide-format type.

Advantages of milling machines.

If you compare automated drilling and milling installations and small-sized milling machines with program control, it will immediately become clear that the latter have a number of positive advantages:

• Small dimensions.
• Low cost.
• Creates little noise.
• Minimal vibration during operation.
• Simplicity of design.
• Versatility.

Such machines are issued high accuracy when processing parts with a rather complex geometric shape. At the same time, the processing process occurs quite quickly and efficiently.

The process of operation of a machine equipped with a CNC is monitored by only one operator who starts computer program. That is, it is possible to operate several machines simultaneously, under the control of one person.

If at one time equipment equipped with CNC was used only for industrial purposes, now it is actively used in the processing of metal parts and workpieces from other materials in private workshops.

It is quite possible to make a desktop milling machine with PU on your own directly in a garage. There are quite a few such home craftsmen, and a CNC milling machine is quite expensive compared to conventional equipment.

A type of small-sized milling machines.

Mini-milling machines equipped with a CNC system can be sorted as follows:

1. Equipment for working with metal workpieces.
2. Wood processing equipment.
3. Machines for milling and grinding work.

According to the complexity of the equipment, small-sized milling machines are divided into the following categories:

• Machines that perform purely milling work.
• Milling and grinding machines.
• Universal.
• Milling and turning.
• Milling and drilling.

Mini-milling machines can be successfully used not only for processing metal workpieces, but also wood, stone, plastic and ceramics.

The frame of the cnc mini series machine is made of seamless aluminum profile (wall section 6-8 mm).

The frame profile, thanks to its reinforced structure, can withstand heavy loads while maintaining reliability and rigidity.

Guides

Mini series machines are equipped with roller guides. These roller guides have good characteristics friction, uniformity and smoothness of movement, accuracy of installation movements and maintain accuracy for a long time; They generate little heat and are easy to lubricate. Roller guides are simpler and more economical to use, have higher dynamics, more rigidity of load absorption, are less energy-consuming, better absorb loads (both static and dynamic), and ensure smooth running.

Ball screws

The mini series machines use high-precision (having high precision or created with high precision parameters; high-precision) ball screws with a diameter of 12 mm. The use of these ball screws eliminates the appearance of backlash when moving coordinates, ensures high processing and positioning accuracy, smooth running, and high wear resistance.

Stepper motors

To move the axes on the mini series, stepper motors are used. The main advantage of stepper motors is their accuracy at low cost. The mini series is equipped with stepper motors with steps of 0.8-1.8 degrees, which allows the machine to produce high-precision, high-quality products.

Corrugated protection

All axes of mini series machines are protected by corrugated protection, and this simplifies the process of servicing the machines, and also extends the life of important machine components, such as ball screws and guides, since it prevents sawdust, dust, and debris from getting on the guides and other moving elements of the machine structure.

Aluminum table with T-slots

The table is used to hold the workpiece, which is processed on a CNC machine. The evenness and quality of the table that is used in the machine affects how parallel the processing tool is in different areas. Thanks to the presence of special T grooves in the aluminum table, it is not difficult to attach the workpiece using clamps in any part of the work area, and it is not difficult to install the clamp in the required groove. The aluminum groove table is not susceptible to the negative effects of moisture, as well as lubricants and coolants.

Control unit and software

The mini series machine control unit is assembled from high-quality components from global manufacturers and has reliable protection against electromagnetic interference, in conjunction with prof. The software ensures stable operation of the machine and the quality of manufactured products. The software has a Russian-language control panel and menu, and is also intuitive.

Turning axis + $950 (optional)

Installing a turning axis expands the capabilities of the machine and allows you to do circular milling, this will allow you to produce products such as figurines, chess pieces and other products close to cylindrical.

Milling cutters from 500 rub. (option)

A very important point in the operation of a CNC machine is the selection of cutters. We offer high-quality cutters at a low price, made of steel with a hardness of 55 HRC with tungsten carbide coating, which retains the excellent cutting properties of the cutter for a long time and under heavy loads. A set of collets will allow you to work with tools with different diameters.

PC for machine control + $350/PC complete with monitor + $520 (optional)

An important element in working on a CNC machine is the PC; it is the one that sends command signals to the machine, and the uninterrupted operation of the equipment depends on it. We have selected a PC with the optimal set of components for trouble-free operation, so that you can enjoy the operation of the machine, and not have to worry about setting it up.

Prof. spindle power 1.5 kW +$300 (optional)

Benchtop CNC milling machines are a worthy alternative to their large factory counterparts. In terms of functionality and precision of processing of products, they are not inferior, and due to their smaller weight and dimensions they can be used not only in any small-scale production, but even at home.

It is actually a smaller copy. The desktop unit is designed to perform the same types of operations in the manufacture of products of complex shapes: milling, drilling, boring, countersinking, and so on. And the principle of its operation is the same, but unlike large machines, it can only process workpieces of much smaller sizes. But desktop CNC milling equipment can be used as an engraving machine. Large industrial units cannot cope with such work.

Dimensions of desktop CNC milling equipment are no more than 910x880x880 mm. But for some models the table length can exceed 1 m (usually 1135 or 1150 mm). The weight of the machines ranges from several tens to 200 kg. They are powered from a 220 V network. Maximum height The workpiece (working area) of desktop CNC machines varies from 40 to 200 mm, and the spindle power ranges from 0.7–1.5 kW.

There are two types of such machines. On console general form, the design and operating principle are similar to those available.

For portal ones, the spindle is fixed to a transverse beam between two vertical posts, which can be stationary or move along the Y axis. Accordingly, the work table, together with the workpiece attached to it, either moves along the Y axis or is stationary. The spindle moves not only vertically (Z axis), but also along the X axis - along the beam between the posts.

Spindle of Gantry Table CNC Machine

Equipment is controlled from connected via USB port personal computer with the Windows operating system via a special software(software) and/or using the machine’s DSP controller (depending on the configuration of the CNC unit). The program can be loaded from external memory media, and the computer is disconnected while the machine is running (also depends on its model). Using the software, you can control workpiece processing manually via DSP or create a program that fully automates all operations.

All machines allow 2D and 3D processing, and some equipment even 4D and 5D. Types of processed materials: from plastic and wood to non-ferrous metals, stone and steel. These capabilities of the machine depend on its purpose and model. Many units are equipped, and others can be optionally equipped with a chip ejector, a spindle cooling system, a rotary device used during the processing of conical products, and other auxiliary units.

In the description of machines you may find the abbreviation CNC - this is the English designation for CNC equipment.

The machines are used in dental laboratories, as well as research and educational institutes, high-precision production of any workshops, including jewelry. They are used for milling, drilling, polishing, grinding, and engraving work at home in the manufacture of small products. The machines produce or process parts of furniture, interior design, advertising media, and so on; stamps, seals, souvenirs and jewelry, radio circuit boards, etc.

Desktop CNC milling equipment is used not only by individuals who love and know how to do something with the help of machines, small workshops and workshops, small industries, but even in large enterprises. On the latter, they mainly prefer to install units designed for metal processing. Such a wide range of applications of desktop CNC milling equipment is due to its main advantages:

• relative ease of operation;
• light weight and compactness;
• mobility;
• simpler design and maintenance compared to large machines;
• connection to a 220 V power supply;
• relatively low cost;
• low power consumption;
• the noise level is within acceptable values ​​and most often significantly lower than them;
• much higher productivity compared to manual control equipment;
• reducing the need of enterprises for qualified milling operators;
• minimum time for transition to processing or manufacturing of new or different types of parts.

For large enterprises, the point of using desktop equipment is that for the manufacture of small parts it is not necessary to use large, and therefore more energy-consuming, machines. In addition, they are not worth it without work, and buying additional ones is very expensive. In addition, not every large machine can handle the fine milling work that a desktop unit is designed for.

Benchtop unit for fine milling

The peculiarity of operating CNC equipment is that you do not have to be a qualified milling machine operator to operate it. The operator operating such a machine only needs to properly secure the workpiece, and then load and run a program in which the unit will perform all the necessary operations without human intervention. It would seem that everything is very simple. It’s just that writing a program for CNC milling equipment requires special qualifications. We need a specialist who knows how to use the CAD/CAM system for such a machine. It includes:

• directly CNC with its software (command system);
• a computer used to control the machine via CNC and write a program for it, and the necessary software on it.

That is, an untrained person who bought a desktop CNC milling or milling-engraving unit will have to learn how to use it and the necessary software, with which they will need to:

• draw drawings,
• create three-dimensional (3D) models of products,
• write programs for a CNC machine based on the created drawings and models.

In addition to solving these problems, when operating CNC equipment, it is also necessary to monitor the correctness of its operation.

Externally, CNC milling and engraving desktop equipment may not differ at all from simply milling equipment. It depends on the models and designs of machines of both types. And the scope of application of milling and engraving units is the same as described for milling units above. And the latter, as noted earlier, can also be used for engraving work. What is their difference?

Milling machines are more focused on performing this particular type of work, and with an engraving attachment they are more geared towards engraving.

Tabletop CNC milling and engraving equipment

Milling equipment can process steel, but engraving equipment cannot, only non-ferrous metals and not very hard materials. But it can be used to perform any delicate, literally jewelry work. You can’t do this with milling equipment. Only on an engraving machine can you always obtain a product that is functionally complete in all respects and does not require additional processing or finishing. In milling, this depends on the level of processing accuracy required and feasible on the equipment.

In order for the engraving unit to perform its high-precision work quickly, safely and without defects, its technical equipment must include a product height sensor. It not only speeds up processing, but also prevents damage to the engraver or micro-mill. In addition, the engraving machine can be equipped with sensors: curvature (tilt) of the product, measuring the length and reach of the tool. They additionally ensure precision machining and cutting depth.

All desktop CNC machines have a limitation on the maximum dimensions of the workpieces processed. It is structurally incorporated into the device of the milling equipment and is determined by the dimensions of the processing area along the X and Y axes, as well as the height and stroke of the spindle along Z. But this limitation does not apply to the German desktop units BZT of the PF series.

German tabletop unit BZT PF series

These CNC machines can process workpieces with dimensions exceeding the values ​​of the spindle movement parameters along the X, Y and Z axes. To do this, it is enough to remove the work table of the BZT-PF metal equipment, on which the milled product should be mounted. This mode of operation in these machines is provided structurally and programmatically. After this, you can process the workpieces:

1. Much greater height than provided with the desktop not removed. In this case, the machine must be installed on additional supports that will raise it relative to the workpiece being processed, fixed, for example, in a rotary chuck or a bench vice.
2. With any surface sizes. That is, the restriction on the length of processing along the X and Y axes is completely removed. In this case, the machine is placed directly on the workpiece itself, and then moved along it. Before starting work, the milled surface is programmatically divided into fragments (sections), along which the CNC unit is moved sequentially as the product is processed.

Another one additional opportunity, which is not provided on all desktop CNC milling units - monitoring of possible failures and correcting the operation of the machine when they occur directly during the processing of the product, which allows you to prevent defects and significantly increase productivity. This function is performed by special servo controllers. Currently, only some high-precision machines with stepper motors, usually milling and engraving machines, are equipped with them.

5 Equipment-constructor - assemble the desired machine yourself

Another advantage of desktop CNC milling equipment is the ability to purchase the machine as a construction kit. Such a unit will cost much less than a ready-made one. In addition, when you purchase a construction kit, you will be able to select the required configuration. That is, you will only need to pay for those milling equipment options that you will use. And if you need to expand the capabilities of the machine, this can be easily done at any time by purchasing the necessary modules and parts.

Kits for assembling desktop CNC milling equipment are deservedly in fairly high demand. And the point here is not mainly the lower price compared to ready-made machines. It is important that in this case, a self-assembled unit, as a rule (depending on the model of the construction kit and its manufacturer), is not inferior in terms of its properties and quality of product processing to similar ready-made factory equipment. It is covered by the same warranty period for maintenance and technical support throughout its lifetime.

It usually takes about 3-4 hours to assemble a benchtop CNC router yourself. Attached instructions with photos and detailed explanations eliminates the possibility of getting confused when designing or setting up a machine, or getting confused in its incomprehensible elements or complex diagrams.
