Laser engraving or laser cutting is to converge the laser beam into a small spot through a focusing mirror and project it onto the surface of an object. The focal point reaches a high power density. At this time, the irradiated part of the material is quickly heated and vaporized, and the laser beam and the material move relatively linearly, so as to realize laser engraving cutting plans.
When the laser engraving machine or laser cutting machine is working for a long time, the optical path will deviate, which will affect the cutting effect. Only the perfect cooperation of laser tube, reflecting mirror frame (A, B, C), focusing lens and corresponding adjustment device can achieve the best effect and process the best projects. This is the core part of using CO2 laser machine. Therefore, it is very necessary to check the laser beam path and adjust it regularly.
8 Steps to Adjust and Align CO2 Laser Beam Path:
1. Turn on the air pump, the air flow is discharged under the trolley, and the wires on the X and Y axis drives of the right control box are pulled away.
2. Turn on the machine switch, the LCD display on the operation panel shows "The system is starting, please wait ..." At this time, the machine is in the reset state, wait for about half a minute, then the LCD displays: File name: AAA Processing speed 100% processing Power: 100/100% Processing quantity 1 Delete. At this time, the machine is in the initial online state.
3. Stick a round cardboard larger than the lens in front of the first reflective lens and the second reflective lens.
4. Put a large cardboard in front of the laser head of the tube, press the fire button on the operation panel, the laser tube emits light, and adjust the laser to the first reflection by adjusting the front and rear positions of the laser tube bracket and the thickness of the rubber under the tube The middle of the lens.
5. Adjust the laser to the middle of the second reflective lens by adjusting the three screw shafts behind the first reflective lens. When adjusting the second reflective lens, the X-axis beam should be moved to the front and back, the point where the laser hits Be completely coincident.
6. Adjust the laser to the hole on the left side of the laser head by adjusting the three screw shafts behind the second reflective lens. When the laser head moves to the four corners of the worktable, the laser must hit the middle of the hole.
7. Focus adjustment.
Focal length refers to the distance (4-4.2mm) between the top of the cone head under the laser head and the surface of the material.
8. By adjusting the tightness of the three screws on the mirror above the laser head, the laser can be adjusted to the vertical angle to ensure the verticality of the cutting surface when cutting.More Infomation »
The operation of CNC router has always been a concern for many prospective customers, because in everyone’s impression, it must be difficult to operate this kind of high-precision CNC equipment with fully automated machining to achieve exquisite engraving effects. So many people retreat before they understand and learn, fearing that they won't be able to learn. In fact, it is a very complicated and cumbersome operation of CNC router. As long as you learn it with your heart, it is easy, and there is nothing difficult to learn. Here we introduce the operation steps of CNC router in details for your reference.
Before starting up, first make sure that all connections between the machine tool and the computer are normal, and then turn on the power supply of the machine tool and computer. After the system is started, enter the Ncstudio CNC system.
2. Mechanical Reset (Optional)
This section is only involved in the machine tool with the function of returning to the machine origin, and the content in this section is involved. Please refer to the machine manual.
If the machine tool supports the operation of returning to the mechanical origin, select the "Back to Mechanical Origin" menu. The machine tool will automatically return to the mechanical origin and correct the system coordinate system.
In some cases, such as after the last normal shutdown, restarting and continuing the last operation, the user does not need to perform a mechanical reset operation. Because the NCStudio system saves the current coordinate information when it exits normally.
In addition, if the user confirms that the current location is correct, this operation may not be performed.
3. Load CNC Files
Before machining, the user generally needs to load the required CNC files, otherwise, some functions related to automatic processing are invalid.
Select "Open (F)|Open (O)..." menu, a standard Windows file operation dialog box will pop up, from which you can select the drive, path and file name where the file to be opened is located.
After clicking the "Open" button, the file is loaded into the system. At this time, the user can press the F2 key to switch to the "File" window to view the current CNC file.
4. Manual Operation
Display manual operation interface
Select "View (V)|Display Manual Interface (M)" menu item, the parameter display window will display a manual operation interface, through this interface, you can manually operate the machine tool.
The machine tool can be moved manually through the corresponding keys on the computer numeric keypad. The NUMLOCK light on the small keyboard should be on at this time.
The corresponding keys are:
6 - X axis positive direction
4 - X axis negative direction
8 - Y axis positive direction
2 - Y axis negative direction
9 - Z axis positive direction
1 - Z axis negative direction
These keys can be combined with CTRL to realize manual high-speed movement of the machine tool.
Use the +/- keys on the keypad with the number keys to quickly increase and decrease the depth.
5. Determine The Origin of The Workpiece
The origin of the X, Y, and Z coordinates in the processing program is the workpiece origin. Before processing, we need to associate the position with the actual position. The steps are:
Manually move the machine tool X and Y to the desired origin position on the workpiece, select the "Set current point as workpiece origin" menu, or clear the coordinate value of the current position in the coordinate window, so that the current position will be used when the processing program is executed. The position is the starting point for processing.
The above steps have completed the workpiece origin setting of the X and Y axes, but the workpiece origin setting of the Z axis requires more precise operation means. This system cooperates with machine tool hardware to provide Z-axis tool setting function.
Select "Operation (O)|Automatic tool setting (E)..." function to complete automatic tool setting, refer to XXX.
After the above two steps, the origin of the processed workpiece has been determined.
6. Perform Automatic Processing
Automatic processing means that the machine tool automatically processes according to the selected processing program.
Start automatic processing
Select the "Operation (O)|Start or Continue (S)" menu item, and the machine tool will automatically start the automatic machining process from the first sentence of the machining program.
In the process of automatic processing, if the operation of the processing program is stopped and the "Operation (O)|Stop (O)" menu item is selected, the machine tool will stop processing after the current statement processing is completed and enter the "idle" state. This method is a method to make the system stop accurately and orderly, and it is also a recommended method.
Note: When the high-speed smooth speed connection feature is valid, the system will stop when the connection speed is zero.
In the process of automatic processing, in case of emergency, select "Operation (O)|Emergency stop (B)" menu item, and the machine tool will stop processing immediately. If you want to restart processing, you must first select "Operation (O)|Emergency stop recovery" (R)" menu and then select "Operate (O)|Start or Continue (S)" menu, the machine tool will restart the automatic processing process from the first sentence of the processing program, otherwise the machine tool will not work.
During automatic processing, if you need to pause processing, select the "Operation (O) | Pause (P)" menu item, and the machine tool will stop processing after executing the current processing statement. At this time, if you want to continue executing the processing program, just select " Operation (O)|Start or Continue (S)" menu item.
Program skip execution Select the "Advanced Start (A)" menu item, and a dialog box will pop up, asking you to execute from the first sentence of the program to the end of the program. If you fill in the sentence number, click "Start" "Key, the machine tool will only execute a certain sentence in the program according to your requirements. But there must be a segment number before executing this function program statement.
7. Direct Positioning Function
If you often want to locate a certain point quickly, you can try the "direct positioning function" function.
The shortcut key to enter the "direct positioning function" function is F5, and the shortcut key to exit the "direct positioning function" function is Esc.
Input the + sign before X in the "Direct Positioning Function" window to realize incremental input.
Enter * in front of X in the "Direct Positioning Function" window to realize mechanical coordinate positioning.
Enter the @ sign in front of the X in the "Direct Positioning Function" window to realize the function of correcting the workpiece origin (including increasing the depth)
8. Shut Down
After the program is processed, turn off the power supply of the machine tool and the computer. If necessary, turn off the main power supply in order to guarantee.
Since Windows is a time-sharing operating system, in general, other tasks (such as editing processing programs) can be performed on the computer during automatic processing, but there are two points to note:
1. Windows programs occupy a large amount of memory, so it is not easy to open too many windows at the same time, generally depending on the size of the computer's memory.
2. Some applications themselves may not be stable, such as some game programs, VCD players, etc., they may ingest system resources unlimitedly during operation, such as memory, CPU time slices, etc., which may eventually lead to The computer freezes. Therefore, during the processing, please do not start these programs to avoid unexpected processing interruption due to machine crash.
In the process of returning to the machine origin, there may be different processes according to the requirements of different systems. In a system with high accuracy requirements, the final calibration process is relatively slow due to the high accuracy requirements. At this time, pay attention to the CNC status window and wait for the system to enter the idle state before exiting the machine origin window, otherwise the machine origin process It was not completed normally and was aborted.
Consequences of being artificially suspended during the process of returning to the machine origin:
1. Port alarm status often appears, because the new number of limit (mechanical origin) has not disappeared;
2. Inaccurate positioning, the calibration function of returning to the machine origin is artificially destroyed;
3. The soft limit does not work: Since the process of returning to the machine origin is not completed, the system is invalid at this time. The soft limit function will only work after the process of returning to the machine origin is completed.More Infomation »

Laser cutting cross section will form a vertical lines, the depth of the texture of the cut surface of the roughness of the cut surface, the more shallow lines, the more smooth cut section. Roughness not only affects the appearance of the edges, but also affect the friction characteristics, in most cases, it is necessary to minimize the roughness, so the more shallow texture, the higher the quality of the cut.
If the sheet thickness exceeds 10mm, the verticality of cutting edge is very important. Away from the focus, the laser beam becomes divergent, according to the location of the focus, cutting to the top or bottom of the variable width. Cutting edge off the vertical line of a few millimeters, the edge of the more vertical, the higher the quality of cutting.
3. Cutting width
Kerf width generally does not affect the cutting quality, only in the internal components formed special precision contour, cutting width is important. This is because the cutting width determines the contour of the minimum, when the plate thickness increases, the cutting width also increases. So want to guarantee the same high precision, no matter how much the width of the cut, the workpiece in the laser cutting machine processing area should be constant.
High speed cutting thick plate, the molten metal will not appear in the vertical laser beam below the incision, but will be sprayed out at the laser beam side. As a result, the curved lines are formed on the cutting edge, and the lines are closely followed by the laser beam. In order to correct the problem, the feed rate can be reduced at the end of the cutting process.
Burr formation is a very important factor to determine the quality of laser cutting, because the removal of burr need extra work, so the amount of burr is serious and how much is able to directly determine the quality of cutting.
6. Material Deposition
Laser cutting machine before the beginning of melting and perforation of the workpiece surface with a layer of oil on the surface of a special liquid. Gasification and all kinds of materials, the material does not need to use the wind to blow the cut, but the upward or downward discharge also can form the deposition on the surface.
7. Sag and Corrosion
Sag and corrosion have adverse effects on the surface of the cutting edge, affecting the appearance. They appear in the error of the cut which is generally supposed to be avoided.
8. Heat Affected Zone
In laser cutting, the area near the notch is heated. At the same time, the structure of the metal changes. For example, some of the metals can be hardened. The heat affected zone refers to the depth of the area that is changed by the internal structure.
If the cutting makes the component heat, it will deform. This is particularly important in fine processing, because the profile and connecting pieces are usually only a few millimeters wide. Control of laser power and the use of short laser pulses can reduce the parts to become hot, to avoid deformation.More Infomation »
NC (Numerical Control)
NC is a technology that uses digital signals to automatically control objects (such as the motion of the machine tool and its working process), referred to as numerical control.
NC technology refers to the automatic control technology that uses numbers, letters and symbols to program a certain working process.
NC system refers to the organic integrated system of software and hardware modules that realize the functions of NC technology. It is the carrier of NC technology.
CNC System (Computer Numerical Control System)
CNC (Computer Numerical Control) system refers to the numerical control system with computer as the core.
CNC Machine Tools
CNC machine refers to a machine tool that uses CNC technology to control the machining process, or a machine tool equipped with a CNC system.
The term numerical control is a widely accepted and commonly used term in the machine tool industry. Numerical Control (NC) enables an operator to communicate with machine tools through a series of numbers and symbols.
NC which quickly became CNC (Computer Numerical Control) has brought tremendous changes to the manufacturing industry. New machine tools in CNC have enabled industry to consistently produce parts to accuracies undreamed of only a few years ago. The same part can be reproduced to the same degree of accuracy any number of times if the CNC program has been properly prepared and the computer properly programmed. The operating commands which control the machine tool are executed automatically with amazing speed, accuracy, efficiency, and repeatability.
The machine is connected to a computer, the computer will tell it where to move. First, the CNC operator should do the toolpath creation, the operator uses a software program to draw the shapes and create the tool path that the machine will follow.
The ever-increasing use of CNC in industry has created a need for personnel who are knowledgeable about and capable of preparing the programs which guide the machine tools to produce parts to the required shape and accuracy. With this in mind, the authors have prepared this textbook to take the mystery out of CNC - to put it into a logical sequence and express it in simple language that everyone can understand. The preparation of a program is explained in a logical step-by-step procedure, with practical examples to guide the user.
CNC technology consists of three parts: machine tool body, CNC system and peripheral technology.
The machine tool body is mainly composed of basic parts such as bed, column, guide rail, working table and other supporting parts such as tool holder and tool magazine.
The numerical control system is composed of input / output equipment, computer numerical control (CNC) device, Programmable Logic Control (PLC), spindle servo drive device, feed servo drive device and measuring device. Among them, the CNC device is the core of the numerical control system.
Peripheral technology mainly includes tool technology (mainly refers to tool system), programming technology, and management technology.
CNC: Computer Numerical Control.
G-Code: A universal numerical control (NC) machine tool language that specifies axis points to which the machine will move.
CAD: Computer Aided Design.
CAM: Computer Aided Manufacturing.
Grid: The minimum movement, or feed, of the router head. Head automatically moves to next grid position when button is toggled in continuous or step mode.
PLT (HPGL): Standard language for printing vector-based line drawings, supported by CAD files.
Toolpath: User-defined, coded route which the cutter follows to machine the workpiece. A “pocket” toolpath cuts the surface of the workpiece; a “profile” or “contour” toolpath cuts completely through to separate the workpiece shape.
Step Down: Distance in Z-axis that the cutting tool plunges into the material.
Step Over: Maximum distance in X or Y axis that cutting tool will engage with uncut material.
Stepper Motor: A DC motor that moves in discrete steps by receiving signals, or “pulses” in a particular sequence, thus resulting in very precise positioning and speed control.
Spindle Speed: Rotational speed of cutting tool (RPM).
Conventional Cut: Cutter rotates against direction of feed. Results in minimal chatter but can lead to tearout in certain woods.
Subtractive Method: The bit removes material to create shapes. (Opposite of additive method.)
Feed Rate: Speed at which the cutting tool moves through the workpiece.
Home Position (Machine Zero): Machine-designated zero point determined by physical limit switches. (It does not identify actual work origin when processing a workpiece.)
Climb Cut: Cutter rotates with direction of feed. Climb cutting prevents tearout, but can lead to chatter marks with a straight-fluted bit; a spiral-fluted bit will reduce chatter.
Work Origin (Work Zero): The user-designated zero point for the workpiece, from which the head will perform all it's cutting. X, Y and Z axes are set to zero.
LCD: Liquid Crystal Display (used on the controller).
U Disk: External data storage device that is inserted into a USB interface.
1. Improve Processing Accuracy.
CNC machine tools are highly integrated mechatronic products, which are composed of precision machinery and automatic control systems. They have high positioning accuracy and repeat positioning accuracy. The transmission system of the machine tool and the structure of the machine tool have high rigidity and heat. Stability; measures to reduce errors were adopted when designing the transmission structure, and it was automatically compensated by the CNC system. Therefore, the CNC machine tool has a higher processing accuracy, especially the consistency of parts processing in the same batch, and the product quality is stable The pass rate is high, which is incomparable with ordinary machine tools.
2. Improve Production Efficiency.
CNC machine tools can use a larger amount of cutting, which effectively saves processing time. CNC machine tools or machining centers also have automatic speed change, automatic tool change and other automatic operation functions, which greatly shorten the auxiliary time, and once a stable processing process is formed, there is no need to perform inter-process inspection and measurement. Therefore, the productivity of CNC machining is 3-4 times higher than that of ordinary machine tools, or even more.
3. Improve Adaptability.
The CNC machine tool performs automatic processing according to the CNC program of the processed parts. When the processing object changes, as long as the CNC program is changed, there is no need to use special process equipment such as masters and templates. This is helpful to shorten the production preparation cycle and promote product replacement.
4. Improve the Machinability of Parts.
Some mechanical parts formed by complex curves and curved surfaces are difficult to process or even impossible to complete with conventional techniques and manual operations, and can be easily realized by CNC machine tools using multi-coordinate axes linkage.
5. Improve Economic Efficiency.
CNC machine tools (especially machining centers) mostly use process concentration, and one machine is multi-purpose. In the case of one clamping, most parts of the parts can be processed. One CNC machine tool or machining center can replace several ordinary machine tools. This can not only reduce clamping errors, save auxiliary time between transportation, measurement, and clamping between processes, but also reduce the types of machine tools, save machine tool area, and bring higher economic benefits.
