We supply end mill head for Mesto.
It is made in 4 segements.
The material can be appointed by customers.
For the mill head,we can supply it in finished machining.
Mill head is always not easy to make.
At the beginning,we only make the mill head as a whole one.
Now we supply mill head to Mesto in half or quarter for sag mills.
If the mill head is in quarter,we should leave enough margin to avoid curving.
Recently we get some small orders for segement mill heads from CITIC.
2)Customers' inspection and packing
The flange areas and outer face use wooden board to protect and fixed by bolt
Use 120×120×2120mmm wooden pad to support the bottom of flange.
All line bolt holes using rubber plug sealing

We do the test according to diffrent production step,
such as chemical composition,UT,MT and mechanical property.
In 2021,Haitai inspection and testing center got approval from CNAS.
There are five main steps of inspection and testings to guarantee the quality of large steel castings:dimension accuracy, chemical composition,mechanical property,ultrasonic test and magnetic powder inspection.
Dimension Inspection for the pattern
Done by engineer
Chemical composition before and after pouring
Casting in blank
