There are many vulnerable parts on the rotary cutting machine, mainly including the feed screw, the clamping shaft and the shaft sleeve, the main slide way and the slide block, the dipstick holder, the tool holder mating surface, etc. After these wearing parts are seriously worn, the accuracy of the equipment will be reduced, and the quality of the single plate will also be affected. Here is a detailed introduction of the impact of wearing parts.
If the feed screw or nut is worn, the tool holder will be loose. At this time, the thickness of the veneer will be different.
The wear of the clamping shaft and the shaft sleeve will make the shaft loose, which will cause out of round rotation, and also result in different thickness of the single plate.
The wear of the main slide will change the cutting angle of the rotary cutting tool during the rotary cutting, resulting in the thickness of the single plate in the outer circle, the thickness of the inner circle, or the wave shape.
The surface of the caliper holder or knife holder is seriously worn, which will cause horizontal sliding. When rotating, the wood will push the caliper back, which increases the gap of the knife door, resulting in insufficient pressure of the caliper on the veneer and rough veneer.
