Reasons for the fracture and crack of the tungsten steel TCT saw blade of the automatic saw blade grinding machine
 
 
Tungsten steel saw blade production equipment explained that the causes of tungsten steel alloy saw blade fracture and crack are basically the same. In addition to the above reasons, the following problems should be solved to avoid frequent fracture:
 
1. In order to avoid excessive saw band tension, all manually tensioned sawing machines must be reduced when they are off work.
 
2. The top guide block does not fit the back of the saw band, and the saw band is bent and broken when cutting force is applied.
 
3. If the tooth type of the band saw blade is too large or too small, the cutting performance will decrease and premature damage will occur.
 
4. The back of the saw blade rubs against the stop of the rim. Adjust the gap between the back of the saw blade and the stop of 1 mm.
 
5. The two saw wheels are not parallel, and the tension on the teeth and back of the saw blade is different, and the side with greater force is more prone to cracks.
 
6. If the line speed is too fast, cracks will be formed due to early fatigue of the saw band, and high-speed cutting should be avoided.
 
The difference between gear grinding machine and gear hobbing machine of automatic saw blade grinding machine
 
What is a band saw blade grinding machine? What is a hobbing machine? They are different machines. Do you know all of these? Today the editor will come to you to appreciate their world.
 
1. The gear hobbing machine uses a hob to rough and finish spur gears, helical gears, herringbone gears and worm gears according to the generative method. The processing range is wide and can reach high precision or high productivity. The gear grinding machine uses a grinding wheel to finish processing and quenching. High-precision machine tools with hard cylindrical gears or gear cutter tooth surfaces.
 
2. Gear hobbing machine is the most widely used machine tool in gear processing machine tools. It can cut straight and helical cylindrical gears, as well as worm gears, sprockets, etc. on the gear hobbing machine. A gear processing machine for machining straight, helical and herringbone cylindrical gears and worm gears with a hob according to the generative method. This machine tool can also process various special tooth-shaped workpieces such as splines and sprockets when special hobs are used. The machining accuracy of the ordinary gear hobbing machine is 7 to 6 (JB179-83), and the high precision gear hobbing machine is 4 to 3. The machining diameter is up to 15 meters.
