How much do you know about the CNC rotary cutting machine?

The emergence of CNC rotary cutting machines not only improves the quality and precision of the production of veneers but also greatly improves the production efficiency and the degree of automation of the whole machine. The peeling machine is one of the main pieces of equipment for producing plywood. The CNC rotary cutting machine is divided into a card rotary cutting machine and a card-free rotary cutting machine. The card rotary cutting machine is suitable for large-diameter wood, and the card-free rotary cutting machine is used for small-diameter wood.

What is the basic principle of the CNC rotary cutting machine?

The CNC rotary cutting machine is used to peel wood sections into veneers. The general method of rotary cutting is: the left and right chuck shafts clamp the ends of the wood section and drive it to rotate. The blade of the rotary knife installed on the knife bed is parallel to the axis of the chuck shaft and feeds along its vertical direction, along the direction of the annual ring of the wood section. Rotary cut-out veneers of equal thickness.

Whether it is constant speed rotary cutting or constant linear speed rotary cutting, to obtain a certain thickness of the veneer, the feed rate of the cutter bed should be kept constant for each rotation of the chuck shaft, and the feed rate is equal to the veneer The nominal thickness. By changing this feed rate, veneers of different thicknesses can be obtained.

 

What are the classifications of CNC rotary cutting machines?

1. The size range of the rotary cutting wood segment, the CNC rotary cutting machine can be divided into three types: large, medium, and small. Large-scale CNC rotary cutting machines can cut wood sections with a length of 2000～2700mm and a diameter of 1600mm; medium-sized CNC rotary cutting machines have a length of 1350～1950mm and a diameter of 200～800mm, and the length of small-scale peeling machines Generally, the diameter is below 1000mm and the diameter is below 400mm.

2. According to whether the wood segment rotates around its axis, the CNC rotary cutting machine can be divided into two types: concentric peeling and eccentric peeling. In the eccentric peeling machine, the wood section can be clamped by the clamp shaft or clamped by the clamp beam. The eccentric rotary cutting machine can obtain beautiful radial patterns, but the productivity is lower than that of the concentric rotary cutting machine. At present, the technologically advanced peeling machine adopts constant linear speed cutting, hydraulic double-chuck axis, and mechanical centering or laser centering technology, so that the linear speed of the CNC rotary cutting machine can reach 3m/s; the quality of the veneer is greatly improved; The minimum veneer thickness is 0.25mm and there are more than 50 specifications.

 

How to reduce noise during the use of a CNC rotary cutting machine?

First, adjust the knives of the CNC rotary cutting machine properly.

To debug the knife gap, you have to adjust the current. Remember that a large current indicates a large pressure, and a high pressure indicates a small gap. On the contrary, a small current indicates a small gap pressure, and a small pressure indicates a gap cutter.
