Due to the decreasing forest resources worldwide, the shortage of high-quality raw materials has become a major constraint on the development of the wood industry. Maximizing the utilization rate is the primary task of the wood industry, and developing various types of engineered wood products to improve their quality and application range is the most effective way to efficiently utilize timber resources. Additionally, developing full-tree utilization, reducing processing losses, and improving processing accuracy can also increase the utilization rate of timber to a certain extent.

Production efficiency and level of automation

Improving the production efficiency of multiple-blade log sawing involves two aspects: shortening processing time and reducing auxiliary time.

How to shorten the processing time of multiple-blade log sawing?

1.In addition to increasing cutting speed and feed rate, the main measure to shorten processing time is process consolidation. Due to factors such as woodworking tools, vibrations, and noise, cutting speed and feed rate cannot be increased indefinitely. Therefore, multi-blade through-feed machines and centralized processing centers have become the main directions for development.

2.The quality of multiple-blade saw blades is crucial.

When adjusting the rotation of the multiple-blade saw blades, they should transmit cutting force while maintaining operational stability. Excellent multiple-blade saw blades not only have static dimensional accuracy but also have exceptional dynamic characteristics, ensuring high precision in wood cutting.

When multiple saw blades cut continuously, the heat generated by the alloy teeth cutting is conducted to the saw plate, causing a rapid increase in the saw plate’s temperature. High-quality saw plates can maintain high precision under such conditions, while poor-quality saw blades may cause the saw plate to warp, affecting the accuracy of sawing.

Alloy teeth can be sharpened multiple times, extending their service life. The quality of hard alloy welding is also crucial, with thin and uniform weld seams allowing the saw teeth to withstand greater cutting forces.

How to reduce auxiliary time?

1.Woodworking machinery operators must be proficient in the construction, performance, operation, and maintenance methods of various machinery, and dedicated personnel should be assigned for their use and responsibility.

2.When operating the multiple-blade log saw, operators should wear appropriate work clothes, secure cuff sleeves, and female workers must wear protective headgear with their hair tucked in. Gloves, scarves, and other accessories should not be worn during operation.

3.Protective covers and guards should be installed for the shafts, chains, pulleys, belts, and other moving parts of woodworking machinery.

4.Before starting work each day, check the machine’s lubrication system to ensure it is in good condition.

A double-end milling machine that combines functions such as sawing, milling, drilling, mortising, and sanding; a edge banding machine that integrates multiple processing techniques; a CNC machining center that combines various cutting processes of multiple-blade sawing of logs – these are examples of equipment designed to streamline and optimize wood processing.

To reduce auxiliary work time, the focus is on minimizing non-processing time. This can be achieved by using machining centers with tool changers or by implementing CNC production lines with automatic worktable exchange capabilities between flexible processing units. These approaches help minimize auxiliary work time to its lowest level.
