According to the structure, it is divided into horizontal metal band saw machines and vertical metal band saw machines. Horizontal metal band saw machines are further divided into scissor-type, double-column and single-column band saw machines;
According to the usage, it can be divided into manual type (economic type, manual feeding type, manual cutting type) and automatic type;
According to the automatic program of the controller, it can be divided into manual type (semi-automatic manual feeding) and fully automatic type (automatic feeding, automatic cutting);
According to the requirements of the cutting angle, it can be divided into angle sawing machine (can saw 90°, 45° angle) and non-angle sawing machine, that is, 90° vertical cutting.
At present, the advanced band saw machine belongs to the hydraulic double-column band saw machine. It is fast and efficient, and is very popular among domestic and foreign processing plants.
Horizontal band saw machine
The saw frame of a horizontal band saw machine is either horizontal or inclined. During operation, the saw frame performs a downward vertical feed action, which cooperates with the rotational movement of the band saw blade to jointly complete the sawing operation. Horizontal band saws can be further classified into three types based on their structural features: scissor type, column type (double column, single column), and rotary horizontal band saws.
Scissors Horizontal band saw
Its machine tool is similar to a scissor structure, with the saw frame feeding perpendicularly around the pivot. Its advantage is that the saw blade can change the running Angle under the minimum external force, ensuring the accuracy of the cutting surface of the workpiece, extending the service life of the saw blade, and the replacement of the saw blade is relatively simple. It is suitable for processing workpieces with smaller diameters. The drawback is that it is limited by the size of the material, and the sawing effect and stability are not good for larger materials.
CNC horizontal band saw with scissors
The CNC horizontal band saw with scissors is similar in function to the above-mentioned scissors type, but it is equipped with an automatic clamping device, an automatic feeding device, and an automatic fixed-length device, which can achieve an automatic working cycle. Compared with the ordinary scissors type, the processing size is stable and the efficiency is greatly improved. Studies have shown that in mass production, it can increase efficiency by 30% to 50% compared with ordinary ones, and is particularly suitable for large-scale processing in the manufacturing industry.
Double-column horizontal metal band saw machine series features:
Double-column structure, vertical lifting, high stability; Hydraulic control of cutting speed, stepless speed regulation; Hydraulic clamping of workpiece, easy operation; Customized three-way hydraulic tightening device; This product has the characteristics of compact structure, stable performance, simple operation, high production efficiency, strong safety, etc; saw blade breakage induction, automatic emergency stop
For enterprises with a limited budget and small diameters of materials to be processed, a scissor sawing machine is sufficient. It has a lower construction cost and maintenance cost than the column-type sawing machine. It uses medium-sized spare parts and motors, and the diameter of the processed materials is small. The requirements for the overall machine configuration are not high. It has a high cost performance, is practical and cost-effective.
When choosing a band saw blade, it is necessary to inform the band saw machine manufacturer of the nature and characteristics of the material to be saw. Based on the performance characteristics of the saw material, it is recommended whether to use a bimetallic band saw blade or a hard alloy band saw blade for sawing. At present, in the band saw blade market, band saw blade manufacturers have generally classified saw blades into copper and aluminum colored band saw blades, thin-walled pipe/lightweight profile saw blades, thick-walled pipe/section steel saw blades, carbon steel saw blades, bundled small diameter material band saw blades, bearing steel saw blades, tool steel saw blades, stainless steel saw blades, titanium alloy band saw blades, grinding tool steel saw blades, nickel alloy band saw blades, etc. according to the types of metals saw.
Specific purchasing steps of the band saw blade:
1. Determine the sawing material:
Understanding the type of material to be cut, such as wood, metal, plastic, etc., determines the required sawtooth characteristics and material.
2. Determine the sawtooth feature:
Number of teeth: The number of teeth refers to the number of saw teeth per inch on the saw blade. The more teeth there are, the more suitable it is for cutting small bends or complex shapes. However, too few teeth will reduce the cutting speed.
Pitch: Pitch refers to the distance between two adjacent teeth. The larger the pitch, the faster the cutting speed, but if the pitch is too small, the accuracy will be reduced.
Edge types: Edge types include straight teeth, wavy teeth, helical teeth, etc. Different edge types are suitable for different materials and sawing requirements.
3. Select materials:
Bimetallic band saw blade: Suitable for materials with high hardness, such as metals, it has good durability and a long service life.
High-carbon band saw blade: Suitable for soft materials such as wood, with a relatively low cost.
Carbon steel band saw blade: It is suitable for general cutting requirements and has good balancing performance.
4. Select size:
Length: The length of the band saw blade needs to match the saw blade wheel of the band saw machine. If it is too long or too short, it will affect the sawing effect.
Width: The width of the saw blade should be selected based on the thickness and type of the material to be cut. Both too wide and too narrow widths will affect the sawing quality and efficiency.
