The difference between frame saw machine and multi-blade saw

A frame saw machine is a wood sawing machine that uses a connecting rod crank to drive a metal saw frame to move up and down or left and right repeatedly.

A frame saw machine can be installed with multiple saw blades according to the thickness requirements of the processing board. Within the sawing range, multiple saw blades can be installed according to the thickness requirements of the processing board, and multiple boards of different thicknesses can be sawed at one time. The saw blade is in good tension, the sawing precision is high, and the surface quality is good. Since multiple positioning, clamping, side feeding and other operation processes are avoided, the auxiliary time is shortened, there is no empty stroke, and therefore the production efficiency is high.

Multi-blade saws cut wood at the same time by combining multiple saw blades. Compared with single-blade saws, this method can significantly improve processing speed and efficiency. It is widely used in the wood processing industry, such as fir, poplar, pine, etc., and is also used in furniture making, keel processing and other fields.

The log multi-blade saw can be regarded as one of the most efficient log board processing machinery and equipment. It has the advantages of fast and smooth feeding, high efficiency, low consumables, safety, reliability and low price. Multi-blade saw machine, the output of one device can produce 20 to 30 cubic meters of wood per day, which is 4 to 7 times that of ordinary band saw processing. At the same time, because the saw blade is hidden inside the casing, the safety is greatly improved. Therefore, the multi-blade saw can also be called a slot machine, because its feeding port is like a tiger’s big mouth.

Frame saw machine and multi-blade saws are two commonly used equipment in the wood processing industry. They have significant differences in structure, working principle, processing efficiency and application scenarios.

1. Structure and working principle

Frame saw machines: Frame saws use the reciprocating motion of the saw frame to cut wood. The saw frame can move vertically or horizontally, and this motion produces greater inertia and vibration, affecting the cutting speed and efficiency.

Multi-blade saws: Multi-blade saws are composed of multiple saw blades that cut wood simultaneously through a rotating cutter disc. This design enables multi-blade saws to cut wood into multiple pieces at one time, which is suitable for large-scale production.

2. Processing efficiency

Frame saw machines: The processing efficiency is relatively low because the reciprocating motion of the saw frame limits the increase in cutting speed. In addition, the feed rate and saw frame stroke of the frame saw will also affect production efficiency.

Multi-blade saws: The processing efficiency is high and can quickly process large amounts of wood, usually 4 to 7 times the processing efficiency of ordinary band saws.

3. Application scenarios

Frame saw machine: Mainly used in the lumber industry, especially in some countries in Northern and Eastern Europe, frame saw is the main equipment of the lumber industry, suitable for scenes that require continuous and automated production.

Multi-blade saw: Widely used in furniture manufacturing, construction wood processing and other fields, especially in occasions where large amounts of wood need to be cut efficiently.

4. Yield and quality

Frame saw machine: The yield is relatively low because it cannot reasonably saw down according to the defects of the wood, and the quality requirements of the logs are high.

Multi-blade saw: Usually requires higher saw blade quality to ensure cutting accuracy and surface finish, and is designed to make more efficient use of wood and reduce waste.

5. Maintenance and cost

Frame saw machine: The maintenance cost is high because the reciprocating motion of the saw frame increases the wear of parts and requires regular maintenance and replacement of parts.

Multi-blade saw: Maintenance is relatively simple, but the initial investment may be high because it requires multiple high-quality saw blades.
