Cross Cutting

Beech log cross cutting is the second stage of the beech veneer production process at Alesta UA. In this process, conditioned logs from the steaming pools are cross cut to the appropriate lengths according to the technical specifications of the peeling machine and the target product dimensions.

Why is Cross Cutting Important?

Conditioned beech logs can vary in length and diameter. Since the peeling machine operates within specific size ranges, it is essential to bring the logs within these parameters. Correct cross cutting increases machine efficiency during the peeling stage, reduces waste rates, and ensures dimensional consistency of the veneer sheets.

How Does the Cross Cutting Process Work?

In the cross cutting process, conditioned beech logs are brought to target lengths using specialised cross cutting equipment. Each log is assessed for its diameter and length and processed according to the most efficient cutting plan. Maximum utilisation of raw material, waste minimisation, and production continuity are the primary objectives at this stage. Cross cutting means cutting perpendicular to the grain of the log, ensuring optimum loading of the peeling machine.

Impact on Quality

Beech logs cross cut to the correct length are loaded into the peeling machine without issue and maintain a stable rotation throughout the peeling process. This directly contributes to beech veneer sheets being produced with consistent thickness and smooth surface quality. Incorrect cross cutting, on the other hand, can lead to machine stoppages, increased waste, and reduced quality.

At Alesta UA, the cross cutting stage is a critical process that is continuously optimised for production efficiency and raw material conservation.

F.A.Q

What is the cross cutting process?

Cross cutting is the process of cutting conditioned beech logs transversely to the appropriate lengths for the peeling machine. This cut made perpendicular to the grain of the log is necessary for the peeling process to be carried out efficiently and with quality.
What lengths are the logs cross cut to?

Cross cutting lengths are determined according to the technical capacity of the peeling machine and the target veneer sheet dimensions. The optimum length is calculated and applied separately for each production batch
How does cross cutting affect waste rates?

An efficient cross cutting plan ensures maximum veneer sheet yield from each log. With incorrect cross cutting, the end sections of the log become unusable, increasing the waste rate.
Is cross cutting part of quality control?

Yes. At Alesta UA, the cross cutting stage is monitored as part of quality control since it directly affects production efficiency and final product quality, and is evaluated separately for each production batch.
