SLCNC flatbed digital cutter uses a high-speed, micro-oscillating blade coupled with a feed motion to cut through the cardboard along a predetermined path, achieving high-speed, clean cutting and slitting. It also utilizes auxiliary tools such as a pinch roller, V-cutter, and CCD camera to perform creasing, slotting, and printed cardboard cutting.
Personnel and Safety
After operator training, familiarize yourself with the machine operating procedures, safety devices, and emergency stop points.
Clear the work area of obstructions and loose tools.
Equipment Inspection
Before starting the work, make sure the vacuum suction is functioning and safety devices such as limit switches, emergency stops, and light barriers are in good condition.
Check blade attachment, handle, and blade for looseness; check power supply and transmission mechanism.
Clean the cutting surface (dust-free and corrugated paper debris-free) and check that the suction system is unobstructed.
Tools Selection
Select the appropriate blade and length; sometimes, a creasing blade or V-cutter is used.
For printed cardboard, the CCD camera must be properly adjusted.
Material Preparation
Confirm that the cardboard type, thickness, and size match the drawing settings. Ensure the cardboard is flat and placed on the work surface.
File
Import vector toolpaths (DXF/AI/PLT/etc.), check the toolpath closure, direction, and presence of overlapping or duplicate cuts.
Perform layout to optimize material utilization.
Place the cardboard flat on the cutting table and use the red light to locate the cutting position. The vacuum suction system automatically activates during cutting to securely hold the cardboard.
Blade Depth. The blade's tip should extend just past the bottom of the cardboard and not too far that it damages the felt on the work surface.
The pressure wheel's depth should allow a clear fold without breaking the cardboard.
Cutting Speed. If you cut too slow you will not work efficiently—and if you cut too fast, you will have uneven edges or incomplete cuts.
Suction Force. Decide if you want to turn on zoned suction, depending on the size of the material. If the material is too small, the suction force will not be enough to hold the cardboard without zoned suction.
Graphic Settings. The cardboard processing process may use multiple tools, such as cutting and creasing. Therefore, you need to set the corresponding tools in the graphics. Our cardboard cutting machine uses line color to distinguish tools.
1. Conduct a trial using only a single piece of scrap material or scrap that is from the same material and batch.
2. Inspect for penetration, edge burrs, dimensional tolerances, and slot fit.
3. Depending on the result of the trial cutting, a small adjustment can be made. If penetration is not achieved, increase the cutting depth or decrease the feed rate; if excessive burrs, adjust the vibration frequency or the blade type; if corrugation for some reason is flat, increase the press roller height.
6. Actual Cutting
1. Start the program, and the cardboard cutting machine will automatically cut according to the tool path.
2. The operator should carefully monitor the first few boards: observe suction, tool vibration, and cut quality. 3. After completing a batch, stop the machine and inspect the blade edge and dimensions to ensure continuous stability.
1. Remove the finished product and any scrap material from the workbench.
2. Quality Inspection: Inspect appearance, dimensions, and mating parts; spot checks are conducted according to QC requirements.
Incomplete Cut/Broken Edge
Cause: Inadequate cut depth, too much speed, a dull blade, or a hard material.
Solution: Increase cut depth or decrease speed, replace the blade, and cut again.
Edge Burrs/Tears
Cause: Wrong blade amplitude/frequency or too much feed rate, improper blade angle.
Solution: Decrease feed rate, modify vibration parameters, or select the correct blade type.
Workpiece Shift/Deviation
Cause: Not enough vacuum.
Solution: Review the vacuum pump/suction force or zone suction.
Frequent Tool Damage
Cause: Excessive speed and abnormal vibration. Action: Check whether the oscillating blade is vibrating normally and reduce the cutting speed.
1. Power down the machine and disconnect it from the electrical supply.
2. Once the cutter head comes to an absolute stop, wearing protective gloves, loosen the blade retainer and remove the old blade (place it in the blade recycling box).
3. Put the new blade on and tighten it to the manufacturer's torque specifications. Reset the height of the blade and check the location of the blade.
4. Perform a dry cut (without material) to confirm there are no abnormal noises or deviations. Then perform a test cut to confirm quality.
Daily: Clean the work surface; inspect the blade for obvious wear; and check for proper vacuum.
Weekly: Check the drive belt tension, lubrication oil, and tighten the screws.
Monthly: Calibrate the coordinate system and check the motor and control system alarm logs.
1. Pre-startup checks: Emergency stop/light barrier/vacuum/tool (√)
2. Import file & verify tool path (√)
3. Load and position material (√)
4. Test cut (at least one piece) and record parameters (√)
5. Production cut (first observe the first board at half speed)
6. Spot check every 50–200 pieces (or as required by QC)
7. Clean and record tool life and issues before leaving get off work
Begin with the tool depth set slightly shallow. Several shallow cuts are much safer, and will provide better quality than one deep cut.
Make the cut for the inner hole first, and outer contour second. This will help prevent the workpiece from moving before the second cut is made.
Don't forget to record the "Material-Parameter" table (set aside a group of empirical parameters for the same type of cardboard) to transfer to the next time and adjust from there.
