Multi Blade Saw : The Ultimate Guide

Multi-blade saw is a kind of mechanical equipment widely used in the woodworking industry. It is designed to process various wood and wood products. The main function of multi-blade saw is to process logs into boards of different specifications or thicknesses. Its working principle is to quickly cut logs into multiple boards through multiple saw blades working at the same time. This kind of machinery usually has the characteristics of fast and smooth feeding, high efficiency, low consumables, safety and reliability. Multi-blade saw can process a large amount of wood every day, which is 4-7 times the processing efficiency of ordinary band saws. In addition, because the saw blade is hidden inside the casing, the safety is greatly improved.

The basic principle of multi-blade saw Multi-blade saw consists of a series of parallel arranged saw blades, which are usually fixed on a rotating cutter disc. When the wood passes through the multi-blade saw, the cutter disc rotates rapidly, and the saw blade cuts on the surface of the wood, thereby realizing the cutting of the wood. Multi-blade saw has high cutting efficiency and can quickly complete a large number of wood processing tasks.

The saw blades of multi-blade saws are generally made of alloy materials with high hardness and wear resistance. The saw blade has a wide range of diameters, and the multi-blade saw can adapt to different processing needs and can efficiently complete the cutting task.

Advantages of multi-blade saws Multi-blade saws have many advantages over traditional single-blade saws. First, multi-blade saws can perform multi-layer cutting at a time, which effectively improves production efficiency. Second, multi-blade saws have high cutting accuracy and can ensure the size and flatness of wood.

In addition, multi-blade saws are easy to operate. You only need to push the wood into the blade to complete the cutting, eliminating the tedious process of manual sawing.

1.Round log multi-blade saw

It is mainly used for the initial processing of round logs, and for cutting and squaring round logs. At present, the round log multi-blade saw can cut wood from 60mm to 500mm. The cutting speed is fast and the dust removal effect is good. The closed sawing environment makes production safer.

2.Square wood multi-blade saw

It is mainly used for cutting square wood strips. The processing height can reach up to 250mm, which basically meets the height requirements of cutting all kinds of square wood. Thickened spindle, heavier model, high-power motor make production more stable and cutting smoother.

3.Plank multi-blade saw

The plate multi-blade saw produced by Dahua Woodworking Machinery is mainly used for cutting plywood, multi-layer board, solid wood board, density board, PVC board, LVL board and other boards. The equipment can meet the production needs of boards of different sizes; polyurethane coated roller, no damage to the board during sawing; anti-wire shaft clamping device, no burrs when cutting, smoother cross section.

No matter which industry, the importance of efficiency is self-evident. The emergence of multi-blade saws has made it possible to finely manage the wood processing industry. Compared with band saws, the processing efficiency of log multi-blade saws is four times that of band saws. Multi-blade saws have the characteristics of stable material yield, high processing efficiency, and simple operation. These characteristics are the prerequisites for the realization of automation and fine management in the wood processing industry.

The surface quality of wood processed by band saws is not ideal, and the subsequent work still needs to process the surface of the wood processed by band saws. The saw teeth of the saw blades of multi-blade saws are made of super-hard alloy steel, and the saw blade speed is 3000-4000 rpm. At such a high speed, the wood is cut, and the surface is smoother and neater than that of wood processed by band saws. It can even be used directly without subsequent process treatment, which also saves time for the entire production process.

Multi-blade saws represent the most advanced log processing technology in the world. With the development and maturity of log multi-blade saw technology, multi-blade saw processing technology will become the mainstream of log processing technology. In developed China, multi-blade saw technology has replaced traditional band saw processing technology.

Advantages of multi-blade saw technology:

1. The saw blade can be flexibly adjusted on the shaft through the hydraulic waiting mechanism to process wood of different specifications

2. The sawing accuracy of multi-blade saw processing is high and the surface quality of sawn wood is good

3. Multi-blade saw processing can design production lines with high degree of automation.

Multi-blade saw R&D technology content is high, resulting in high equipment prices, but due to the many advantages of multi-blade saws, it will definitely become the mainstream process of wood in the future, which is also the requirement of global market competition for the log processing industry.

Finally, let’s look at one of the most time-saving key technologies of multi-blade saws. As the name suggests, a multi-blade saw is a device composed of multiple saw blades. In fact, a more accurate name for a multi-blade saw should be a multi-saw blade double-axis circular saw machine. It is composed of two upper and lower or left and right main shafts, and each main shaft is equipped with 4-16 saw blades. It can be seen that the number of sheets produced each time is at least 3-15 pieces. Compared with the band saw that only produces one sheet of sheet material each time, the efficiency doubling is obvious.

For more precise and accurate cuts, a multi-blade saw is a must-have tool for any woodworker. The upward-cutting action of the saw blade ensures a cleaner, smoother surface. Learn more about the features and benefits of this useful tool, as well as tips to ensure you get the most from your next project with a multi-blade saw.

1.Achieve optimal cutting efficiency.

With a multi-blade saw, you can achieve optimal cutting efficiency. The upward-cutting action of the saw blade means that the wood fibers are cleanly cut in one cut, resulting in an even surface with less chance of error. Plus, because the saw blade cuts forward, rather than back and forth like a traditional saw, you can save time and complete projects faster.

2.Resawing boards into smaller pieces.

A multi-blade saw can also be used to resawing boards into smaller pieces. Woodworkers often use this technique when they need to create new parts from a single board, such as making furniture legs or other narrow parts. Because the saw blade moves in an oval, rather than back and forth, resawing with a multi-blade saw can be done quickly, accurately and efficiently.

3.Get consistent results with repeatable cuts.

A multi-blade saw is the perfect tool for consistent, repeatable cuts. The special saw blades used by these saws move in an oval shape, following the contours of the spaces between their teeth, ensuring very precise cuts. This allows woodworkers to achieve more consistent results than with other types of power saws. Additionally, since multi-blade saws can be used for resawing tasks, such as making furniture legs or parts from a single board, they can save time and money on purchasing pre-made products.

4.Make your rip saw more powerful by using additional blades.

Multi-blade saws typically come with a single blade, but their capabilities can be further enhanced by using additional blades. Installing a crosscut/miter blade on a multi-blade saw opens up new possibilities for creating angled mitre joints, mortises, and tenons. Additionally, you can alternate between different types of blades depending on the material you are cutting and the task at hand. For example, if you are cutting harder woods, such as oak or walnut, switching to a high-speed steel (HSS) blade may give you better results than using the standard blade that comes with most multi-blade saws.

1. Regularly adjust and check the feed chain, feed motor chain, and navigation motor inside the log multi-blade saw.

2. Regularly check whether the length and tightness of the main motor belt of the log multi-blade saw are appropriate, the oil cup of the box should be regularly filled with oil, and whether the oil pipe has been properly aligned.

3. The buffer sleeve, saw blade and guide piece in the log multi-blade saw should be cleaned with diesel regularly (3-5 days) and wiped with a clean machine cloth. There should be no debris during installation. They should be cleaned and wiped with a cloth.

4. When the main shaft core of the log multi-blade saw is replaced every day, the hole should be flushed with water, or the dirt should be blown out with an air gun at the innermost water outlet to ensure that the water outlet is unobstructed.

5. Check the main shaft nut inside the log multi-blade saw machine regularly to see if it is loose.
