Maintenance and dressing of grinding wheel of carbide saw blade gear grinding machine
 
The grinding surface of the grinding wheel of the alloy-head saw blade gear grinding machine should be smooth, and the grinding toughness should not be cracked
 
To grind high-quality serrations, the grinding surface of the grinding wheel must be a semicircle
 
Grinding wheel used for chamfering, the chamfering surface of the grinding wheel has 2 inclined surfaces
 
Usually the grinding wheel is repaired once every grinding circle
 
When using the grinding wheel to dress the grinding surface of the grinding wheel, the gravity cannot be used, otherwise it is easy to deform the grinding surface of the grinding wheel (maintain the shape of a semicircle)
 
Never dress the left side of the grinding wheel, this will change the angle at which the grinding wheel grinds the saw blade
 
In the early stage of grinding, the speed can be fast, and the last lap must be completed at a slow speed to achieve high-quality serrations.
 
The soft material of the grinding wheel can produce good results, but it needs water cooling
 
Chamfering usually takes four turns to achieve good results
 
Usually burns are caused by too dirty grinding wheel or too fast grinding feed
 
In the grinding process of the alloy-head saw blade gear grinding machine, the originally semi-circular grinding surface will be deformed due to the wear of the grinding wheel. The purpose of dressing the grinding wheel is to restore the deformed grinding wheel to the shape of a garden. During the grinding process, it is necessary to always observe whether the shape of the saw tooth is wrong, and to trim the grinding wheel in time.
 
 
 
 
Requirements for the use of carbide saw blade gear grinding machine production line
 
1. When working, the workpiece should be fixed, and the profile positioning should be in accordance with the direction of the knife, so as to avoid abnormal cutting, do not apply side pressure or curve cutting, and the knife should be stable to avoid the impact of the knife edge contacting the workpiece, which may cause the saw blade to break, or The workpiece flew out and an accident occurred.
 
2. During work, if abnormal sound and vibration, rough cutting surface, or peculiar smell are found, the operation must be terminated immediately, and the faults must be checked in time to avoid accidents.
 
3. When starting and stopping cutting, do not feed the tool too fast to avoid broken teeth and damage.
 
4. If cutting aluminum alloy or other metals, special cooling lubricant should be used to prevent the saw blade from overheating, resulting in tooth paste, and other damage, which affects the cutting quality.
 
5. Equipment chip trough and slag suction device ensure unobstructed, to prevent slag accumulation and agglomeration, affecting production and safety.
 
6. When dry cutting, please do not cut continuously for a long time, so as not to affect the service life and cutting effect of the saw blade; wet cutting should be cut with water to prevent leakage.
