There are many vulnerable parts on the rotary cutting machine, mainly including feed lead screw, clamp shaft and shaft sleeve, main slide way and slide block, pressure gauge holder, tool carrier fitting surface, etc. After these wearing parts are seriously worn, the accuracy of the equipment will be reduced, and the quality of the veneer will also be affected. The following is a detailed introduction to the impact of wear parts after wear.
Feed screw or nut wear tool holder will be loose, at this time the veneer thickness will be different.
Wear of the shaft and sleeve will make the shaft loose, which will cause non-circular rotation, and also cause different thickness of veneer.
The wear of the main slideway will change the cutting angle of the rotary cutting tool during the rotary cutting, resulting in the thickness of the outer single plate, the thin inner ring, or wavy shape.
The pressure gauge holder or tool holder surface is seriously worn, and horizontal sliding will occur. During rotary cutting, the wood will push the pressure gauge back, which will increase the gap of the knife door, resulting in insufficient pressure on the veneer by the pressure gauge, and the veneer produced by rotary cutting is rough.
