CBN inserts used for turning and milling machining process,to test our samples is a good way to check our CBN inserts quality,we welcome you ask us to provide free samples especially for the solid CBN inserts.

 

Please try to provide us as more as possible for the following cutting condition and parameters,this will help us provide you the right CBN grade and edge preparation (chamfer width and angle on cutting edge),or send us the current insert image,packing label so that we can know the size,specification of the tool you are using.

 

1.The workpiece name to be processed,for example:slot roller,automotive brake disk,brake drum,engine,fly wheel,cast iron roller,steel roller,water pump,gear etc.

 

2.The work piece material: like high Cr (Chrome) cast iron,high Ni cast iron,white cast iron,chilled cast iron,gray cast iron,ductile cast iron,HSS steel,harnened steel,bearing steel etc.

 

3.The hardness of the workpiece: HRB or HRC=? like HRC=58 , HRC=65 etc.

 

4.The Cutting / Turning / Milling / Machining method:

Rough Machining / Turning / Cutting ?

Semi-finish machining?

Finishing machining ?

If tool used for finish cutting ,is there a speical surface roughness (RA,RZ) need to achieve after machining ?

 

5.Is the cutting continuous cutting,light interrupted cutting,medium interrupted or heavy interrupted cutting ?

 

6.The cutting/turning speed: V=? m/min or tell us the workpiece diameter and the rotary speed

 

7.The amount of feed/feed motion :f=? mm/r

 

8.The cutting depth: AP=?mm

 

9.Is the cutting process adding coolant or dry cutting ?

 

It is helpful for us to tell us the brand and sizes of the tool you are using and the current cutting parameters you are taking,so that we can provide you the right grade with most approximate edge preparation.
