Quenching process
Quenching hardening play an irreplaceable role in improving the hardness, strength, and wear resistance of products. However, quenching is not a simple process of heating and cooling. It involves complex temperature control, selection of cooling medium, and subsequent processing to ensure that metal products achieve extremely high hardness while avoiding excessive embrittlement.according to customer requirements.Quenching and carburizing process is adopted,make the boring head stronger and more durable

Built in water hole for quick cooling
During the rapid milling process,the blade generates a large amount of frictional heat.The built-in water hole design allows for direct cooling of the blade tip, and the processing
temperature remains basically unchanged for a long time. The hole accuracy is more stable, saving the cost of the blade.

Double sided fastening
The tool holder and boring head adopt side fixed locking,Convenient loading and unloading,The contact surface tightly fits,Good stability and high accuracy during boring machining.

Precision blade position design
Triangle precision blade position firmly fixed blade,Stable and maintain continuous precision.

Simple to use
Simply replace blade pads with different machining ranges,You can change the processing range,Reduce processing costs.

Clear dial scale
Accurate scale can control fine tuning,Each grid movement is 0.01mm,Easy to operate,High cutting accuracy.

Product Size Details
Please note that:
For example: EWN20-36 boring head
It does not mean that the EWN20-36 boring head can meet the machining requirements of 20-36mm, but rather that this requirement needs to be met by replacing three ENH blade holders;
EWN20-36 boring head can replace 3 ENH blade holders:
ENH1-1 processing range 20-26mm;
ENH1-2 processing range 25-31mm;
ENH1-3 processing range 30-36mm;
To meet the machining requirements, replace the three ENH blade holders mentioned above.
EWN boring head includes 1pcs ENH1-1 blade holder, ENH1-2 and ENH1-3 need to be purchased separately.
