Compact and portable CNC router for metal

Industrial CNC milling machine for metal is produced costly for large dimensions. Compact models acquire small organizations for the implementation of single lots. Demand for such installations is observed in the service area. Acquire desktop models of production with unique equipment, in which spare parts are not available for sale. Manufacture of such nodes by third-party organizations exceeds the cost of the machine itself.

Reasons for the popularity of automated machines

The CNC milling cutter for metal is able to produce high-quality products comparable to the requirements of machine-building industries. The design of the equipment allows processing of materials from plastic, wood. Versatility in application and low cost have made axial systems the most popular.

The cutting process is carried out in an automatic cycle. Mini-milling machine with CNC for metal is connected to PC, laptop via USB interface. Only a network of 220 volts is required, which is located practically in any production room. When repairing a car in the garage it turns out to make the simplest details.

Complex forms of the final product require the creation of a competent drawing in 3D format, which is difficult to accomplish with a lack of qualification. The graphic file is converted with the help of common and free programs into G-codes. Ready-made commands are loaded into the controller memory.

What can I do on the machine?

Mini-milling machine with CNC for metal performs the following operations:

  • Milling.
  • Engraving.
  • Drilling.
  • Movement along the bends of the workpiece.
  • Open the material.

The CNC-metal milling cutter makes it possible to manufacture not only the parts necessary for repair, but also to implement shaped models of limited dimensions. Long billets are processed not with desktop versions of equipment, but using portal constructions.

Depending on the design, the CNC system allows the processing of cylindrical workpieces to be clamped into the spindle assembly. The tool remains fixed in this embodiment, the table moves along two coordinates. Flat parts are placed in the clamps on a fixed base.

Completion of the installation

Everyone knows a 3D printer that creates voluminous details by gluing together small pieces. He has several axes and a knot that separates the working substance. The CNC milling cutter works on the same principle. The price of the machine depends on the following components:

  • Rigidity of the structure. Under the treatment of hard alloys it is necessary to provide a strong base, the main pressure is applied to it. Axial guides and bearings are responsible for compensation of the reverse force. The cutting technology is selected to be optimal, so that the main components do not wear out.
  • The purpose of the machine is universal, but can be completed for the needs of a specific task. The additional equipment is a chip scraper, coolant coolant installation. A monitor may not be used to display information. But so the adjustor will be easier and faster to provide repair and readjustment of the machine.
  • The type of the spindle unit makes a significant contribution to the price increase. According to the experience of the masters, it is recommended not to save on an important element. Thus, there are periodic problems with the accuracy of the brand KRESS FHE / FE.
  • Axial movements are carried out by stepping motors.

The main points when choosing a machine

The price tag on the CNC milling cutter for metal can reach several hundred thousand rubles. These include extended versions that have 5 axes. Two additional coordinates are used for the spatial displacement of the spindle. This solution allows you to manufacture complex parts in one operation.

The simplest models of low rigidity and limited functionality are sold for only a few thousand rubles. With their help, quickly made parts of soft metal. The processing speed also depends on the type of tool. The following parameters are taken into account:

  • Noise of rotation of the spindle;
  • Interchangeability of spare parts;
  • Type of mechanisms;
  • Simplicity of installation and commissioning;
  • Weight of equipment;
  • Power consumption;
  • Number of coordinate axes;
  • The possibility of modernization in the future.

Additional Features

The desktop CNC milling cutter for the economical version is connected to the PC via the LPT port. The process control is autonomous, it does not require operator intervention. The processing program adds a forced stop during errors or on demand technology.

The cutting process is converted into 3D graphics by the LinuxCNC program, designed to fully control and display the technological process of CNC machines. Monitoring the status of the installation nodes takes place in real time. The interface of the application is not inferior to the industrial versions of the software.
