Dual channel profile machining centerIt is a high-performance and high-precision CNC machine tool widely used in manufacturing, medical equipment, automotive, aviation, electronics, shipbuilding and other fields, especially suitable for high-speed processing of new energy, aluminum profiles and other materials. Its working principle is based on technologies such as drilling, milling, and threading. It adopts CNC system control and intelligent processing production. The design of two work platforms, two Z-axes, and two tool magazines enables the machine tool to simultaneously process two workpieces or process different parts of a workpiece, greatly improving processing efficiency.
Dual channel profile machining centerOperation steps:
Step 1: Preparation before startup
1. Environmental inspection:
Confirm that the work area is clean and free of obstacles.
Check if the pressure of the compressed air source is within the required range of the equipment (usually 0.5-0.7MPa), and if the FRL triple piece is working properly.
Check that the coolant tank level is sufficient and that there are no leaks in the cooling system.
Ensure that the chip removal system (if any) is unobstructed.
2. Equipment inspection:
Check if the guide rail and screw guard are intact.
Check if the tools in the tool magazine (ATC) are complete, securely installed, and have the correct tool numbers.
Check if the fixture (such as pneumatic/hydraulic clamping device) is intact and the clamping force is normal.
Special attention: Check for foreign objects in the working area of the two processing channels (A channel and B channel) to ensure safety.
3. Preparation of workpieces and fixtures:
Prepare the profile workpieces to be processed and check if their dimensions and materials meet the process requirements.
Correctly and firmly clamp the workpiece onto the fixtures of stations A and B to ensure accurate positioning. Be careful not to exceed the travel range of the machine tool for the workpiece.
Step 2: Power on and reset to zero
1. Connect the power supply:
Turn on the main power switch of the machine tool.
Press the "Power Start" button on the electrical control cabinet to power on the system.
2. Start the CNC system:
Turn on the power of the CNC control panel.
Wait for the system self-test to complete and enter the operation interface.
3. Reference Point Return:
Select the "Return to Zero" (REF) mode on the control panel.
Press the reset buttons for the+X,+Y, and+Z axes in order (specific order according to the manufacturer's requirements) to return each axis to the mechanical origin.
Dual channel note: Confirm that the system correctly identifies the coordinate systems of both channels. Some machine tools may require zeroing or automatic completion of two channels separately.
Step 3: Select and load the machining program
1. Select channel:
On the CNC system interface, find the "Channel Selection" or "Spindle Selection" function.
Select the channel to run (such as "Channel A" or "Channel B"). Some systems support "dual channel synchronization" or "alternating" modes.
2. Loading program:
Enter the program management interface.
Call out the processing program of the corresponding channel from the storage device (USB flash disk, network, internal storage) (for example, O1001_A corresponds to channel A, O1001_B corresponds to channel B).
Key: Ensure that the program for channel A is loaded, and the program for channel B is loaded. Do not confuse them.
3. Program verification (optional but recommended):
Use the "graphic simulation" function to preview the tool path and check for errors such as interference and overtravel.
Run the program at low speed in "Dry Run" mode and observe whether the movements of each axis are normal.
Step 4: Set the workpiece coordinate system (tool alignment)
1. Select the current channel: Ensure that the system is in the channel where the knife needs to be aligned (such as aligning with channel A first).
2. Choose the knife alignment method:
Edge finder tool alignment: used to determine the coordinate origin of the workpiece in the X and Y directions.
Z-direction tool setter/trial cutting method: used to determine the origin of the Z-axis workpiece coordinate system (usually the upper surface of the workpiece).
3. Execute knife alignment:
Install a border finder or standard cutting tool.
Manually move the spindle to make the edge finder contact the side of the workpiece, record the coordinate values, calculate and input them into the corresponding workpiece coordinate system (such as G54-A).
Replace the machining tool, measure the tool length using a tool setter, or measure the Z-value through trial cutting, and input the tool length compensation value into the tool table.
4. Switch channel, repeat tool alignment: Switch to another channel (such as channel B), use its corresponding workpiece and fixture, repeat the above tool alignment steps, and set independent workpiece coordinate systems such as G54-B.
Step 5: Start processing
1. Safety confirmation:
Close all protective doors and ensure that the safety locks are effective.
Confirm again that there are no personnel or foreign objects in the working areas of the two channels.
Check if the coolant and air source are turned on.
2. Select automatic mode:
Turn the mode switch on the control panel to either "AUTO" or "Memory" mode.
3. Select and start the program:
Select the program to run.
Single channel operation: Select a channel (such as channel A), press the "Cycle Start" button, and start processing.
4. Dual channel operation:
Synchronous mode: Start programs for two channels simultaneously (if supported by the system).
Alternating mode: Run the A channel program first, and then automatically or manually switch to the B channel for operation after completion.
5. Monitoring operation:
Closely observe the machining process and listen for the sound of the spindle running to see if it is normal.
Observe the cutting status, chip removal, and whether the coolant injection is in place.
Is there any alarm in the monitoring system.
Step 6: Processing completion and shutdown
1. Program ends:
When the program reaches the M30 or M02 instruction, it automatically stops.
The spindle stops rotating and the feed stops.
2. Remove the workpiece:
Wait for the spindle to finish and stop.
Open the protective door (the safety interlock will disconnect the power).
Release the fixture and remove the processed workpiece.
Clean the chips on the fixture and workbench.
3. Clamping new workpiece: Clamping the next workpiece to be machined, repeating the tool alignment and machining steps.
4. Shutdown:
After completing all processing tasks, turn the mode switch to "emergency stop".
Turn off the power of the CNC control panel.
Turn off the main power switch of the machine tool.
Clean the machine tool, remove chips, and add lubricating oil.
