In addition to the optimization of PCD or PCBN tool material, indexable cuting insert geometric parameters, cbn pcd cutting tool structure and cutting parameters, the main 

factors that affect the cutting performance and tool life have been proved through a lot of practice that a good edge type and edge honing quality are also the premise of 

cutting tool.

Why PCD PCBN inserts honing is needed?

After grinding with ordinary grinding wheel or diamond grinding wheel, there are different degrees of micro notches (i.e. micro chipping and saw edge). The micro notches 

are generally 0.01-0.05mm, or more than 0.1mm in severe cases. In the cutting process, the micro notch of the cutting edge is easy to expand, which speeds up the tool wear

and damage.

Modern high-speed machining and automatic machine tools put forward higher requirements for tool performance and stability. The edge honing technology can solve the micro 

gap problem of the tool edge after grinding, reduce or eliminate the edge value, and achieve a smooth, sharp and durable tool performance.

Benefits of tool honing

Edge rounding: deburring the edge to achieve accurate and consistent rounding.

The edge burr causes tool wear and the surface of workpiece is rough. After honing treatment, the edge becomes very smooth, which greatly reduces the chipping and improves 

the surface finish of workpiece.

The tool groove is polished evenly to improve the surface quality and chip removal performance. The smoother the groove surface is, the better chip removal is, and the higher 

cutting speed can be achieved. At the same time, with the improvement of surface quality, the risk of tool and material biting is reduced. And can reduce 40% of the cutting force, 

make the cutting more smoothly.

A lot of information shows that tool edge honing can effectively extend tool life by 200% or more, greatly reduce tool cost and bring considerable economic benefits to users.
