A circular carbide saw blade is an essential tool in various industries, known for its precision and durability in cutting a wide range of materials. Its primary purpose is to provide clean, accurate cuts, particularly in metalworking, woodworking, and construction applications. The carbide-tipped teeth are what make these blades stand out, as they are significantly harder and more resistant to wear compared to traditional steel blades. This ensures that the blade remains sharp longer, even when cutting through tough materials.

Applications of Circular Carbide Saw Blades

1. Chop Saws Blades for Steel
One of the most common uses of circular carbide saw blades is in chop saws designed for cutting steel. These blades are engineered to handle high-speed, high-temperature conditions, making them ideal for cutting thick metal bars, sheets, and pipes. The precision and strength of these blades ensure a smooth cut, reducing the need for further finishing processes.

2. Metal Saw Cutter
Another crucial application is in metal saw cutters, where the carbide teeth maintain sharpness over extended periods of heavy use. This makes them perfect for cutting a variety of metals, from aluminum to stainless steel. Their ability to maintain their cutting edge means reduced downtime and fewer blade changes, contributing to improved efficiency in production environments.

Why Choose Carbide Saw Blades?

The benefits of using circular carbide saw blades are numerous. Their longevity, precision, and efficiency make them invaluable in industrial settings.

                                           Aluminum Extrusion press for prestressed composite frames

A solid extruder structure is a prerequisite for ensuring the performance of the extruder. After being used for a period of time, many Aluminum extrusion machine become loose, the interfaces age, and the cylinders bend, resulting in deformation and unstable quality during the aluminum extrusion production process. In fact, the main reason is that the extruder as a whole is not strong enough.

The stress during the operation of the extruder is very large, and our extruders mostly adopt a prestressed composite frame structure, which is composed of a high-thickness integral front beam, a high-thickness rear beam, and a square prestressed sleeve to form a closed The prestressed composite frame uses a special hydraulic preloading tool to apply an overpressure tensile load to the entire length of the tie rod, and at the same time applies compressive stress to the pressure sleeve, so that the entire frame is in a stress pretightened state, and the tension column prestress is 115% of the maximum load. above. For example, our 7500-ton hydraulic extrusion press has a front beam thickness of 1950mm made of ZG35Mn, a rear beam thickness of 1800mm (material ZG35Mn), and a square pre-applied sleeve (material ZG35). It can make it bear force better, which is also an important reason for the long service life of the extrusion machine.

Other advantages of prestressed composite frames

1. The center distance of the four stressed tie rods of the frame is symmetrical to the center of the press, so that the entire frame is stressed evenly. The main reason why the quality of aluminum materials produced is stable or unstable is whether the force is uniform. Only by maintaining uniform force can the overall density of the aluminum material be uniform, thereby improving the accuracy of extruded products.

2. The prestressed composite frame frame has a larger bending section, which makes the frame elongation and bending deformation smaller under the action of extrusion force. Therefore, the extrusion beam and the lower part of the extrusion tube can be fixed on the lower frame. The horizontal and vertical guide rails are very convenient for centering adjustment between the extrusion beam, extrusion barrel and mold. The upper frame can be used as an X-shaped moving guide rail for the extrusion barrel. On the premise of ensuring the stability of the machinery, the available space is used to reduce the space occupancy of the machinery.

3. There are two sets of elastic anchoring devices and foundation anchors on the lower part of the rear beam to make the rear beam fixed reliably.

After many years of production experience and continuous improvement based on customer feedback, our extrusion press is currently one of the most stable extruders on the Chinese market and one of the longest-lasting Aluminum extrusion machine.

Extrusion oil and cutting fluids are essential components in the aluminum extrusion machine and deep processing of aluminum profiles. With the increasing demand for high-precision metal processing in the manufacturing industry, metalworking fluids are evolving towards being more environmentally friendly, of higher quality, and technologically advanced. For aluminum extrusion machines, which are large-scale equipment, the comprehensive performance requirements of hydraulic oil are very stringent. Poor-quality hydraulic oil can disrupt normal equipment operation, leading to production line stoppages and significantly impacting the economic benefits of the entire workshop.

Just as engine oil is crucial to the functioning of a car, hydraulic oil is vital to the machinery. It is imperative to further reduce the friction coefficient of hydraulic oil, which will enhance the efficiency and stability of the extrusion press.

Our aluminum extrusion machines have very stringent requirements regarding hydraulic oil and hydraulic systems. We use the most advanced hydraulic oil and systems in the industry. The pump station of the extrusion machine features an integrated design, centrally located at the rear bottom of the machine's oil tank. The system uses imported German Rexroth (Bosch Rexroth) electro-hydraulic proportional control axial piston variable pumps and a domestic stainless steel plate-type circulating filtration cooling system. The pipeline system is designed with necessary buffering and anti-vibration measures, such as buffer pads, flexible hoses, or vibration absorbers, and employs flexible rubber joints to absorb vibrations.

Isolation control valves are designed between the oil pump groups to ensure that when two mechanisms need to operate simultaneously according to the program, they do not interfere with each other. The system can achieve pump isolation, no-load start, pressure regulation, and overload protection functions. The pump head electro-hydraulic proportional valve and electronic control device are imported with the main pump and connected to the main control computer of the aluminum extruder, allowing for integrated control.

As one of the most critical components of the Aluminum extrusion machine, Huananmachine ensure the highest quality standards for our hydraulic oil system. This rigorous quality assurance is a key reason we confidently guarantee the quality to our customers.

You may be curious about how aluminum is made. From aluminum bars to the aluminum we commonly see, it has to go through a variety of processes and is made by a variety of equipment. Below we will introduce several of the most common aluminum production machinery and equipment.

1, Automatic Multi- Billet Hot Shears Furnace. The original aluminum billet is several meters long, which requires the aluminum billet to be cut and heated before the heated aluminum billett can be extruded. Automatic multi aluminum billet hot shears furnace is the newest production equipment which combine heating engineering ,mechanism ,automatic control system , hydraulic , photoelectric and thermometry in one .It is consist of aluminum bar feeding drive transport rack ,furnace ,hot shears, electricity control system and so on .

2, Aluminum extrusion machine. This is a machine that makes aluminum billet into basic aluminum Profile materials. The heated aluminum bar (the length of the aluminum bar is less than half a meter) is squeezed by strong hydraulic pressure. When the aluminum billet is squeezed by the extrusion pressure and passes through the small hole of the mold, the basic aluminum material can be formed.

3, Infrared Die Heating Furnace. Before placing the die into the aluminum extruder, the die needs to be heated. Infrared die heating furnace use iron aluminum alloy wire ,features: high efficiency and energy saving. There installed infrared radiation plate behind of the iron aluminium alloy wire which can reflect heat back to the furnace effectively , radiation plate, iron aluminum alloy wire composed of a set of infrared heater, the heating way is first radiate the heating energy in form of electromagnetic energy to the furnace hearth,then the mold absorb the electromagnetic energy and converted into heat energy.

4, Automatic Double Puller (Three Heads).This machine is used to extrusion profile traction and cutting operation. The aluminum coming out of the aluminum extruder needs to be pulled and cut to length and placed.The profile is led out of the mold cavity straightly and cooled under tension, preventing the profile from being uneven in length, hanging, or twisting, thereby improving the quality of the aluminum material.

5,Handling Table Production Line. The main function is to place and cool the aluminum. The temperature of the aluminum coming out of the extruder is relatively high and needs to be cooled naturally before the next step of processing.

6, Aluminium Profile Double Doors Ageing Furnace. Aluminum profile ageing furnace is the equipment in the process of aluminum profile heat treatment. The extruded aluminum profile needs aging heat treatment before it undering electrophoretic polishing and oxidation surface treatment technology. Aging of aluminum profile is one of the key processes of heat treatment. The heating rate and the uniformity of furnace temperature are strictly required in this process, and the aging temperature of the process is mostly (210 ±5) ℃.

In addition to the above important aluminum production equipment, there are some frequently used equipment, such as: Nitriding Furnace, Film Laminating Machine, Wrapping Machine, Hot top Casting table.

  Our screw barrels are engineered for longevity, offering significantly greater durability than those of our competitors. For instance, the service life of our FLY-220 machine can reach up to 16,000 tons, compared to the industry standard of around 9,000 tons before a replacement is needed.

During production, we subject our raw materials to rigorous quenching and tempering processes, ensuring stability and resistance to deformation under high temperatures. Additionally, the high-temperature zone of the screw groove is treated with nickel alloy spraying, further enhancing material hardness. These combined advantages contribute to the screw's remarkable durability.

It's important to note that screws vary in nitriding time, cost, and lifespan depending on the supplier, with differences in processing precision reflecting varying management levels.

Moreover, our screw barrel features an 80mm wall thickness, providing superior heat retention and minimizing the impact of external temperatures. In contrast, the typical wall thickness of our competitors' barrels is only 70mm.

2. Gearbox

Our gearboxes, manufactured by the renowned Jiangsu Sanlian brand, utilize a four-axis coupling with a reduction ratio of 1:40. This design, compared to the two-stage transmission with a 1:20 reduction ratio used by many competitors, results in a 20% reduction in electricity consumption, delivering more stable product output and a more efficient design.

3. Machine Body Structure

Our machines are constructed with square steel tubes, and the base is built with robust materials, ensuring stability and resistance to deformation. Unlike the channel steel commonly used by others, our machine frame is approximately one-third heavier, offering enhanced structural integrity and reliability.
