How to deal with some problems in the process of using the double head CNC rotary cutting machine?

1. Malfunction: The end of the board skin is too thin.

Reason: The knife of the double head CNC rotary cutting machine is too low and the knife gap is small, and the knife position needs to be adjusted.

2. Fault: The end of the board's skin is thick and curled.

Reason: The knife of the double head CNC rotary cutting machine is too high and the knife seam is large, and the knife position needs to be adjusted.

3. Failure: The machine is laborious.

Reason: The sliding part of the double head CNC rotary cutting machine lacks oil, the pressure is too high, and the knife is high.

Remedy: add lubricating oil to the sliding part to reduce the single roller and knife position.

4. Malfunction: The slab skin becomes asbestos tile.

Reason: The knife gap of the double head CNC rotary cutting machine is small and the knife feed is fast.

Remedy: adjust the knife seam and change the feed speed.

5. Failure: the uneven thickness of the cross-section of the sheet.

Reason: The blade is not straight.

Remedy: Re-sharpening the knife, and adjust the slit of the knife with a thin iron sheet or tape.

What is the workflow of the double head CNC rotary cutting machine?

The plywood production process of the double-head double head CNC rotary cutting machine: Log (artificial fast-growing and high-yield diameter wood)-fixed-thickness peeling circle with a pinch shaft-thick core board without a pinch shaft-peeling-veneer stress Degradation of the front side-the stress of the peeling veneer, the degradation of the reverse side-the stress of the peeling veneer, the frontal degradation of the stress-drying-single-sided cutting 45° lead angle trimming diagonal seam splicing-gluing-blank assembly, splicing (cold pressing )-Hot pressing-saw edge-fixed thickness sanding-check and storage-finished plywood.

What are the developments of the double head CNC rotary cutting machine?

1. The successful development of the shaftless rotary cutting machine in the 1980s strongly promoted the development of the plywood industry. The machine can cut wood cores and wood sections with a diameter of less than 200 mm. The minimum diameter of the wood core can be 50 mm, and the cutting speed can reach 120-180 m/min.

2. To improve the quality of the peeling veneer, a double head CNC rotary cutting machine (main rotary knife and auxiliary rotary knife) rotary cutting machine appeared, and the auxiliary knife is used for the rotary cutting of wood segments before turning round knots, bends and other defects. , The impact is large, and the counter-rotating knife is more severely worn; the main rotating knife is used for normal rotary cutting, and the blade is sharp and clean, which is conducive to obtaining high-quality veneers.
