In machining, it is very important for enterprises to use tool passivation machine to improve the production of 

various types of tools. Some enterprises with strict production requirements will often maintain the tool passivation 

machine when using it to ensure the effect of tool passivation, so as to avoid tool replacement. In mechanical 

production, it is very good for enterprises to have such a rigorous attitude. Details can sometimes determine success 

or failure, so we should maintain this attitude when using tool passivation machine. Today we will discuss the benefits

of using tool passivation machine.

In fact, the main function of the tool passivator is to deburr, flatten and polish the tool. This method can improve the 

quality of cutting tools. Specifically, this is because after grinding with ordinary grinding wheel or diamond grinding 

wheel, there are different degrees of clearance on the cutting edge, and the small clearance of the cutting edge is easy 

to expand in the cutting process, thus accelerating the wear and damage of the tool. Therefore, after fine grinding, use 

the tool passivator to passivate the tool, so as to reduce or eliminate its sharp value, so as to achieve smoothness and 

flatness, and make the tool sharp, firm and durable. Specifically, using a tool passivator has the following benefits:

1、 In the passivation process, the burr on the cutting edge of the tool can be removed. When the burr is removed, the 

cutting edge of the tool can be kept in a smooth state, so as to achieve accurate and consistent rounding of the cutting 

edge, because if the cutting edge of the tool has Too many burrs will cause more wear of the tool in the process of use. 

If it is reused in the later stage, it will easily cause the workpiece surface to become very rough. After passivation with 

the tool passivator, the tool edge will become very smooth, which can greatly reduce the probability of edge collapse 

and improve the surface finish of the workpiece in the process of use.

2、 Using the tool passivator can polish the tool groove very evenly, and improve the surface quality and cutting 

performance of the tool. Because the more flat the groove surface of the tool is, the faster the cutting speed will be 

when it is used, and the cutting effect will be better Will perform better. At the same time, when the surface quality 

of the tool groove is improved, the probability of engagement between the tool and the processing material will be 

reduced, and the cutting force of the tool can be reduced by at least 40%, so that the workpiece can be cut more 

smoothly.

3、 Often using the tool surface will produce some small protrusions, so that the tool surface becomes rougher, so that 

the tool is easy to produce greater friction in the cutting process and reduce the cutting speed. After passivation and 

polishing with the tool passivator, the protrusion will be removed, which can make the tool absorb more friction heat in 

the process of use, which greatly reduces the heat loss in the cutting process and greatly improves the cutting speed of 

the tool.
