Universal CNC metal milling machines are suitable for solving extensive production tasks. CNC technology is constantly evolving and the cutter control structure is being improved to accommodate complex cutter movements. The demand for high-speed machine machining centers is constantly increasing. Fully automated control allows you not to interfere in the production process for a long time, which reduces equipment downtime and increases work efficiency.
Why do we need to modernize production?
CNC metal milling machines are produced in Western countries, Korea, Japan, Russia. A wide range of technological products allows you to choose the perfect solution for your business.
The objectives of retrofitting old equipment are:
- Increasing the competitiveness of the enterprise by improving the quality of products.
- Modern electronics reduces the processing time of parts, improves dimensional accuracy. The technological program is converted in an automatic cycle directly on the machine, immediately after loadingto an image application of the set format.
- Updated CNC metal milling machines can work in 5D modes, creating unique contours that cannot be reproduced on previously presented models.
- The rigidity of the machine structure is increased, and, consequently, harder grades are processed at a high speed.
Selection criteria
It is desirable that CNC milling machines for metal have parameters suitable for the conditions. After all, overstating the requirements leads to an increase in the cost of installations. Therefore, it is better to choose the characteristics that are optimal, according to the needs of production. However, the possibility of upgrading the machine in the future must also be taken into account.
CNC metal milling machine has the main parameters that have the greatest impact on the resulting cost of the product:
- Dimensions of the workpiece holding table and its material: aluminum, wood.
- Power of the spindle unit.
- Number of axles.
- Type of work area cooling.
- Way to provide information about the workflow: on the monitor, using a PC.
- Type of bearings, guides, lubrication system, clamping jaws.
What should I look for when inspecting component parts?
CNC metal milling machine must meet the requirements of high rigidity of parts. Often they try to make portal systems from stacked structures. But such constructive solutions do not guarantee sufficient reliability of the assembly. Need to payattention to the fact that the load-bearing parts are made cast, cast iron is selected for them.
Aluminum load-bearing parts can only be selected if CNC wood router. For metal, portable models are made from a similar material in order to achieve a reduction in the weight of the installation. But such a decision imposes a restriction on the type of material being processed.
Electrical components are equally important for the processing of precision metal products. Stepper motors are common, but servo motors are more acceptable. However, the last parts of the machine are more expensive. There are a number of shortcomings in the design of the first motors. One of these is "skipping a step" during the movement of the axis, which will affect the quality of the produced part.
Additional parameters
The milling machine (CNC) for metal is controlled by a controller, which in different models differs in performance, PC communication interface. Often little thought is given to this when choosing small-sized versions. But for the processing center, this node is the main one. A huge number of additional axes need to be controlled in real time, which consumes most of the system's resources.
Often in machines, tasks are divided into several controllers: one is busy with the processing process, and additional ones monitor the position of sensors, communicate with peripheral modules, and reproduce the current process on the monitor screen. The latest versions of the machines are equipped with full-fledged computers, which does not require an external connection. PC.
Compact Models
Portable machines are used for the production of spare parts, models, one-time unique parts. They are applicable in the furniture industry, auto repair shops, for household needs.
Such models can be used for the following purposes:
- cutting sheet material - portal systems;
- PCB manufacturing;
- producing billboards, layouts;
- small-piece production of custom-made parts.
Compact models of milling and engraving machines are quickly dismantled, placed in the trunk of a light car and instantly assembled in a new place. The power supply of the electrical part is designed for a regular 220 V 50 Hz network through a standard socket, which allows you to connect it in the garage, on the street with an extension cord, and even at home.
