Aluminum Saw Blade Types Classification and Application Scen

Aluminum saw blades are indispensable cutting tools widely used in aluminum profile processing, broken bridge aluminum doors and windows, industrial aluminum materials, aluminum pipes, aluminum sheets and aluminum bars processing. According to base material, tooth shape structure, processing precision and supporting equipment, aluminum saw blades can be divided into multiple categories. Different types of saw blades are quite different in sharpness, chip removal capacity, wear resistance and cutting finish, and they also correspond to different aluminum materials and application scenarios. Proper selection can effectively avoid burrs, edge chipping, aluminum adhesion and blade burning, and greatly improve cutting accuracy and production efficiency.

1. Classification by base material and cutter head

1.1 Carbide tipped saw blade

It is welded with high-quality steel base body and tungsten carbide cutter head, featuring high hardness, high temperature resistance, strong wear resistance and not easy to crack teeth. The cutting surface is smooth without burrs and the service life is long. It is the mainstream choice for door and window factories and aluminum processing plants. It is suitable for broken bridge aluminum profiles, industrial aluminum profiles, aluminum square tubes, round tubes, aluminum plates, aluminum bars and most solid and hollow aluminum materials.

1.2 High speed steel saw blade

Integrally made of high-speed steel, the blade edge is good in toughness and not easy to break, with economical price, suitable for low-speed cutting and small-batch processing. The disadvantage is that high temperature resistance and wear resistance are general, and it is easy to passivate after long-time cutting. It is mostly used for thin aluminum sheets, small aluminum profiles and small batch cutting in small workshops.

1.3 Diamond saw blade

The cutter head adopts diamond wear-resistant layer, which has ultra wear resistance, high temperature resistance and super long service life. It is suitable for long-term continuous cutting of super hard aluminum materials and thick aluminum plates. It is widely used in large aluminum material factories, profile deep processing enterprises and automated pipeline high-load operation scenarios.

2. Classification by tooth profile structure

2.1 Left-right alternate tooth

It is the most common general tooth type with alternating left and right arrangement of cutting edges. The chip removal groove is large, chip removal is smooth, cutting resistance is small, and it is not easy to stick aluminum with good heat dissipation effect. It is suitable for ordinary aluminum profiles, aluminum square tubes, round tubes, decorative aluminum materials and conventional blanking of broken bridge aluminum profiles.

2.2 Trapezoidal flat tooth

Adopt high and low staggered tooth design, the high tooth cuts the groove first, and the flat tooth polishes the cutting surface. It has strong anti-chipping ability, mirror-like cutting surface and almost no burrs. It is the first choice for high-precision aluminum cutting. It is suitable for system broken bridge doors and windows, high-end curtain wall aluminum materials, high-gloss decorative profiles and 45-degree angle precise cutting, which can be directly assembled without polishing after cutting.

2.3 Flat tooth

The tooth top is flat and straight with stable cutting performance and small vibration, which will not tear the plate surface. It is suitable for cutting and grooving thin aluminum sheets, aluminum-plastic plates, honeycomb aluminum plates and composite aluminum plates, and is especially suitable for flat cutting of plate materials.

2.4 Arc bottom tooth

The tooth root adopts large arc design with sufficient chip removal space and good heat dissipation performance. It is not easy to accumulate aluminum chips and overheat and burn the blade. It is suitable for solid aluminum bars, thick aluminum strips, large-section heavy industrial aluminum materials and deep cutting blanking operations.

3. Classification by processing precision and purpose

3.1 Economic ordinary saw blade

With moderate tooth number and conventional base material configuration, it is cost-effective, suitable for rough cutting and conventional blanking with low requirements on cutting surface finish. It is commonly used for construction site blanking, ordinary door and window rough cutting and simple cutting of decorative aluminum materials.

3.2 High precision mirror saw blade

Adopt precision gear grinding process with standard tooth shape and high concentricity. The cutting edge is free of burrs and edge chipping, and the surface is smooth, which can be directly assembled without secondary grinding. It is suitable for system broken bridge windows, high-end curtain wall aluminum materials, furniture aluminum profiles and precision aluminum parts processing.

3.3 Burr-free special saw blade

Optimize tooth angle and chip removal groove design, the upper and lower cutting mouths are almost burr-free without hanging aluminum scraps. It is suitable for thin-walled aluminum tubes and hollow precision profiles batch finishing cutting, saving manual deburring process and matching automated assembly line production.

4. Classification by matching equipment

4.1 Handheld aluminum cutting saw blade

Adopt thin base body, match the speed of handheld cutting machine, light and sharp, easy to carry. It is suitable for temporary blanking on construction sites and mobile cutting of aluminum profiles.

4.2 Miter saw special saw blade

Dense tooth design with high precision, suitable for 45-degree oblique cutting and door and window corner cutting, with flat cutting surface and accurate angle. It is the standard matching saw blade for door and window processing plants.

4.3 Fully automatic cutting machine saw blade

Thickened base body, anti-vibration and anti-deformation, resistant to frequent start and stop of long-term continuous operation, stable operation without swinging. It is widely used in fully automatic aluminum cutting machines, CNC blanking machines and industrial automated cutting lines.

5. Application matching summary

Broken bridge aluminum and system aluminum profiles are preferred with trapezoidal flat tooth saw blades; ordinary aluminum square tubes and round tubes adopt left-right alternate tooth saw blades; solid aluminum bars and thick aluminum plates are matched with arc bottom tooth or coarse tooth saw blades with fewer teeth; thin aluminum sheets and aluminum-plastic plates use flat tooth dense tooth saw blades; mass pipeline production chooses diamond or high wear-resistant carbide saw blades.

Reasonably selecting the corresponding saw blade type according to the aluminum material shape and processing precision requirements can realize no edge chipping, no burrs and no aluminum adhesion in cutting, effectively extend the service life of the saw blade and improve the overall processing efficiency.
