What is the reason for uneven thickness of veneer peeling machine

The veneer peeling machine is an important equipment used to cut logs or wood into veneer. However, sometimes we may encounter situations where the thickness of the veneer cut by the peeling machine is uneven. This uneven thickness distribution can affect the quality and effectiveness of the veneer. This article will analyze the reasons for uneven cutting thickness of veneer peeling machines.

Uneven surface quality of logs

The veneer peeling machine relies on the outer surface of the log when cutting wood. If there are problems with bumps, scars, diseases, or distortions on the surface of the log, it is difficult for the peeling machine to maintain a consistent cutting thickness during the cutting process. Uneven log surfaces can lead to inconsistent cutting depth of cutting tools in different areas, resulting in uneven rotary cutting thickness.

Tool wear of the peeling machine

The cutting tool of the peeling machine is one of the key factors. If the tool wear is severe or uneven, it will lead to inconsistent cutting depth, resulting in uneven rotary cutting thickness. Tool wear may be due to prolonged use or unsuitable tool material, requiring timely replacement or repair of the tool.

Improper adjustment of the peeling machine equipment

The veneer peeling machine requires reasonable equipment adjustment and operation to ensure consistency and accuracy of cutting. If the equipment is adjusted improperly, such as inaccurate tool installation angle or mismatched cutting speed, it can lead to uneven rotary cutting thickness. Therefore, operators need to be familiar with the operating points of the peeling machine and make correct equipment adjustments and use according to the manufacturer's instruction manual.

Differences in wood moisture content

The moisture content of wood is one of the important factors affecting the thickness of veneer peeling machine. If the moisture content of the log is uneven, such as inconsistent water content in the cross-section or significant differences between the edge and center parts, the peeling machine will be affected during the cutting process. The difference in wood moisture content can lead to different resistance and elastic deformation during cutting, thereby affecting the consistency of rotary cutting thickness.

Deformation caused by transportation and storage

During the transportation and storage of wood, deformation may occur due to environmental factors such as humidity, temperature, and pressure. These deformations, including bending, twisting, and shrinkage, can lead to uneven surface of the log. If deformed wood is not properly handled, the peeling machine will also be affected during cutting, resulting in uneven peeling thickness.

To solve the problem of uneven thickness in veneer peeling machine, the following measures can be taken:

When selecting logs, pay attention to the surface quality of the logs and avoid selecting logs with obvious surface defects.

Regularly inspect and replace the peeling machine tools to ensure their good condition and cutting consistency.

Adjust and operate the peeling machine equipment according to the manufacturer's instruction manual to ensure good operation and cutting consistency of the equipment.

Control the moisture content of wood, ensure uniform moisture content of logs, and carry out necessary drying treatment to reduce moisture content differences.

During the transportation and storage of wood, appropriate measures should be taken to prevent wood deformation, such as proper stacking, humidity and temperature control, etc.

Uneven thickness of veneer peeling machine may be caused by surface quality of logs, tool wear, improper equipment adjustment, differences in wood moisture content, and transportation and storage. By focusing on the selection of logs, regular inspection of cutting tools, good equipment adjustment and operation, control of wood moisture content, and correct handling of wood deformation, measures can effectively reduce the uneven thickness of rotary cutting, improve the quality and utilization value of veneer.
