Selection method of workpiece for CNC saw blade grinding machine
 
 
The first important thing to consider is the parts you want to produce. The main point is to buy a gear grinding machine that can complete the processing task with the shortest worktable and the smallest tonnage.
 
Carefully consider the material grade and the maximum processing thickness and length. If most of the work is low carbon steel with a thickness of 16 gauge and a maximum length of 10 feet (3.048 meters), then the free bending force does not need to be greater than 50 tons. However, if you are engaged in a large number of bottomed die forming, perhaps you should consider a 160-ton machine tool.
 
Assuming that the maximum thickness of the material is 1/4 inch, 10 feet of free bending requires 200 tons, and the bottomed die bending requires at least 600 tons. If most parts are 5 feet or shorter, the tonnage is almost halved, which greatly reduces the cost of purchase. The length of the part is very important to determine the specifications of the new gear grinding machine.
 
What is the importance of the gear grinding process of the gear grinding machine?
 
There are many requirements for gears of car gearboxes to be ground after hardening, which promotes the development of gear grinding machines. The mass-produced automobile industry is the most important expander of gear transmission, and the gear manufacturing industry develops along with the automobile industry. Today, restricted by environmental protection and energy factors, electric vehicles will become popular, which will have an impact on the production of gears, because electric vehicles no longer need gears and use electric motors to directly drive wheels. In the future, the output of gears may be reduced, and the accuracy and quality will be greatly improved.
 
CNC machine tools also rarely use gears. However, there are still a large number of gear transmissions in the aircraft industry, precision instrumentation and other industries, especially high-speed and heavy-duty gears such as turbine gears. Gear grinding technology is still a necessary method of tooth profile finishing. CNC gear grinding machine is a necessary processing equipment for high-precision gears and high-speed heavy-duty gears. In the past ten years, automobile rear axle spiral bevel gear pairs (especially the Gleason system arc shrink gear transmission) also require a large amount of manufacturing equipment. After the arc shrink tooth spiral bevel gear is heat treated, the finishing process is required. Gear grinding (or grinding gear) machine.
 
Custom saw blades for CNC saw blade grinding machine
 
Number of teeth and tooth profile
 
The number of teeth and tooth profile must be explained in detail when customizing the saw blade. Confirm several times. If the number of teeth or tooth profile is incorrect, it is very easy to cause tooth chipping or cracking during sawing, or even directly cannot be used; For the number of teeth or tooth profile, please refer to "Selection of Number of Teeth of Metal Circular Saw Blade"
 
The thickness of the saw blade is customized
 
The thickness of the saw blade, which is what we often say, will cause waste of materials, and too thin will cause instability in sawing, so you must state it clearly. If you don’t know it well, you can use your own The requirements are given to the manufacturer, and the custom-made manufacturer will also judge based on experience.
 
The diameter of the saw blade
 
This is very simple, you can design according to different sizes of materials (the size of saw blades used for sawing materials of different sizes must correspond to each other).
 
The material of the saw blade
 
Regarding which material should be used for custom saw blades, this needs to be judged according to the material being cut, such as: high-speed steel, hard alloy or cold saw blades. When custom saw blades, they also need to be made according to different materials.
