Dressing technology of grinding wheel of band saw blade gear grinding machine

The grinding wheel gear grinding machine adopts the forming method to grind, and the section accuracy of the grinding wheel is the key, which depends on the section calculation accuracy and the grinding wheel dressing accuracy. The gear grinding machine manufacturers at home and abroad have conducted in-depth research on the shaping wheel dressing technology and developed different grinding wheel dressing devices to ensure the dressing accuracy of the grinding wheel and improve the gear grinding accuracy.

 

There are two main types of dressing for forming grinding wheels: diamond pen and diamond roller. The diamond pen has simple structure and low cost, and theoretically, higher dressing accuracy can be obtained. The diamond pen is severely worn, short in life, difficult to estimate, and cannot be accurately compensated, resulting in poor consistency of sand contour accuracy, which has a greater impact on the grinding of large gears, and is gradually replaced by diamond roller dressing. The diamond roller has high rigidity, large amount of dressing, and high efficiency. It adopts the trajectory envelope method, which is more suitable for dressing complex formed surfaces. Diamond roller dressing methods are divided into plunge-type roller dressing and swing type roller dressing.

 

In the grinding process, the grinding wheel is worn and dull, and the grinding wheel needs to be trimmed to produce a new sharp profile while ensuring consistent accuracy. Grinding wheel dressing tools and dressing conditions have a significant impact on the quality of grinding wheel dressing, which directly determine the shape and profile accuracy of the grinding wheel. The sharpness of the dressing determines the grinding force and grinding temperature. It is necessary to select reasonable grinding wheel dressing parameters.

 

 

 

 

How to keep the saw blade sharp

 

1. Corresponding model and equipment

 

Saw blades have strict requirements. Different models correspond to different equipment. They cannot be matched at will. For example, a saw blade that cuts metal is used to cut wood. This is a very common mistake. Some laymen think that cutting metal is all Yes, it should be faster and sharper to cut wood! If the saw blade used on the metal circular saw is used for sawing wood, the result will be tooth jamming and chipping, the saw blade is consumed too much and the cost is too high.

 

2. Grasp the time to replace the saw blade

 

Saw blades are consumables and have a service life. Many companies think that when cutting and processing, if the service life is not reached, they will not be replaced and will not be used until they are used! It is true, this is what all companies are doing , I think it is normal and reasonable, but I don’t know that this is a very lazy approach;

 

If a saw blade has a life of 40 squares, it should be replaced when it reaches 20 squares. After a break, at least another 30 squares can be cut. People will be more energetic after resting. The product is the same!

 

3. Association with its equipment

 

The quality of the gear grinding machine equipment will also affect the quality of the saw blade. The coordination and compatibility between them are very important. If the best saw blade is placed on a very poor quality equipment, its efficiency will be at least half discounted. .
