Advantages of Metal Cutting CNC Router

Metal cutting CNC router has gradually developed into an independent processing center, which is widely used in building doors and windows, curtain walls, architectural decoration, and vehicle and ship decoration industries. 

In view of the characteristics of metal materials and processing technology, CNC router metal cutting machines generally have the capabilities of milling, drilling, and tapping; while functions such as milling planes/curved surfaces, countersinking, and boring are seldom used in aluminum profile processing. Due to the uniqueness of the processing objects, the big metal cutting cnc router is very different from the general machining center in terms of structural layout, technical parameters and CNC system design.

1. Large processing area

  In order to adapt to the characteristics of metal parts, the CNC router metal engraving machine work surface is mostly narrow and long. The work surface is standard equipped with pneumatic fixtures and positioning backing plates, which is convenient for workpiece positioning and clamping. Aluminum engraving machine has three layouts: gantry type, moving column type, and moving beam type. The three layouts have their own advantages and disadvantages in terms of machine rigidity, stable operation, and convenient operation.

2. High spindle speed

  The spindle speed of an ordinary CNC router machine is generally below 8000rpm; while the spindle speed of a metal cutting CNC router machine can reach or exceed 18000rpm. Due to the high speed, a high-power integrated spindle is generally used to clamp the tool, blow air to clean, and circulate water to cool And other functions are integrated in one. The cooling liquid system is divided into two forms: pouring cooling and spray cooling. The latter belongs to the more advanced concept of quasi-dry cutting and micro-lubrication system, which has high cooling and lubrication efficiency and low coolant consumption, and is especially suitable for metal processing.

3. High precision and moderate rigidity

  The processing accuracy of frame, stile, truss and other profiles involved in doors, windows and curtain walls is generally between IT10 and IT12; plus the processing objects are mostly metal, metal cutting CNC router does not need to pursue excessive positioning accuracy and rigidity. The bed and other structural parts of the aluminum engraving machine are mostly welded by steel plates, so the quality of the machine is high and the service life is longer.

4. High processing efficiency

  Improving processing efficiency is the main goal pursued by metal cutting CNC router. By increasing the rapid feed rate, shortening the tool change time, tool-free setting and fast loading, the auxiliary time and idle travel time are shortened. Engraving machine manufacturers strive to improve the automation of workpiece positioning and card assembly by summarizing the problems encountered by customers in various regions.

 CNC router metal engraving machines are generally equipped with pneumatic fixtures and positioning backing plates. The positioning backing plate is a positioning device driven by an air cylinder, which extends when loading and unloading the workpiece; retracts at the beginning of processing to avoid interference. During use,the profile can be positioned against the board to obtain precise positioning. 

Before the machine leaves the factory, the relative position of the positioning backing plate and the machine origin is accurately adjusted, and the data is stored in the CNC system, so the tool setting process can be omitted. Pneumatic fixtures are operated by buttons or foot switches. The clamping position can be adjusted longitudinally in the machine tool to avoid interference, and at the same time ensure reliable and effective clamping.

How to use metal engraving machine

1. Open the CNC router sheet metal machine engraving programming software and program the engraving path: Let’s take an example, engraving text, first use the software to layout, and then use 2D, 3D, cut, and enter the depth, Parameters such as overlap rate and line spacing are calculated on the computer. When processing the relief, first use ARTCAM or fine engraving to generate the relief from the file or model image, determine the size, input the processing parameters, and the computer starts the calculation. When generating paths, colored lines will be generated for words or models.

2. Output engraving path and input engraving machine control system software: In the output files of software such as Wentai, Jingdiao, ARTCAM, etc., if the engraving machine control system cannot support the format, it needs to be converted. Common program formats are nc, mmg, etc.

3. Check the machine and fix the workpiece correctly: Check whether there are debris on the machine tool, especially stone, large-area stone powder, sand, etc., pay attention to cleaning, otherwise it will easily affect the flatness of the material. Place the workpiece according to the placement direction in the typesetting programming software, depending on whether the material is placed horizontally or vertically. Note that the material and the machine are parallel to the direction of the axis, and do not put it off. Use the pressure plate to fix the material, the general fixing methods are pressure and upper two. When pressing with a pressure plate, please be careful not to press the processed part of the material to prevent mechanical collision or tool collision.

4. Determine the origin of the workpiece coordinate system, which is what we often call tool setting. Align the origin of each axis of the machine with the original point, and then return the data to zero or enter the coordinates of the corresponding coordinates.

5. Detect water spray and water circulation, adjust the mechanical speed and feed speed, and simulate in the aluminum plate engraving machine control system.
