The importance of the automatic saw blade grinding machine manufacturer woodworking saw blade grinding machine grinding process
 
 
 
    There are many requirements for gears in car gearboxes that require grinding after hardening, which promotes the development of gear grinding machines. The mass-produced automotive industry is an important expander of gear transmission, and the gear manufacturing industry has evolved with the automotive industry. Today, due to environmental and energy factors, electric vehicles will be popular, which will have an impact on the production of gears, because electric vehicles can no longer need gears, but use electric motors to directly drive the wheels. Future gears are likely to decrease in production, and will be greatly improved in accuracy and quality.
 
 
 
    Gears are rarely used on CNC machines. However, there are still a large number of gear transmissions in the aircraft industry, precision instrumentation and other industries, especially high-speed heavy-duty gears such as turbine gears. The woodworking saw blade grinding machine grinding process is still a necessary tooth-finishing method. CNC gear grinding machine is the necessary processing equipment for high-precision gears and high-speed heavy-duty gears. In the past ten years, the rear axle spiral bevel gear pair also needs a large number of manufacturing equipment. After the arc-concave tooth spiral bevel gear is heat-treated, the gear grinding machine is required for finishing.

Automatic saw blade grinding machine manufacturers analyze the hardness of the saw blade and the high temperature on the saw blade
 
 
 
    When the carbide saw blade is used, the rotation speed is very fast, and the temperature is also greater than 600 ° C. We remove the problem of the equipment itself. If the alloy saw blade has cracks, it is usually made of material, operation and high temperature. cause.
 
 
 
I. Analysis of the problem of carbide saw blade material
 
 
 
A, the material toughness is insufficient
 
 
 
The material of the carbide saw blade is an alloy. The state of the carbide saw blade is brittle. It is hard but has insufficient toughness. It cannot be hard and hard to use. It must be used by professionals.
 
 
 
B, welding technology
 
 
 
The part of the cutter head and the base body are made by welding (not integral), and the welding technology is required here. The better the welding, the more stable the operation and the lower the possibility of cracks.
 
 
 
C, the material is unqualified
 
 
 
If the cause of the crack is due to the problem of the saw blade itself, there is also a possibility that the material for making the carbide saw blade is not the original ecology, that is to say the used material, the recycled material, which needs to be purchased. It is necessary to check and confirm clearly.
 
 
 
 
 
Second, high temperature analysis of cracks in cemented carbide saw blades
 
 
 
    Carbide saw blades are used for high-speed operation when sawing materials. The temperature during sawing can reach more than 600 °C, which will cause oxidation on the surface of the saw blade, causing different degrees of burns. This is also a hard alloy saw. The fundamental source of the crack, and in the early stage the crack is very small, very slow to be discovered, but we can judge according to the color of the surface. Under normal circumstances, if there is a crack, there will be different colors around it. For example: blue, purple, brown, yellow, etc., which are different oxidation index tungsten oxides;
 
 
 
In order to reduce such cracks caused by high temperatures, the equipment also needs to strengthen the cooling function;
 
 
 
Summary: When using carbide saw blades, we must strictly abide by the relevant regulations, including maintenance when not in use and maintenance after work.
