Everyone knows that stainless steel is a material that is difficult to cut, but it can be seen in turning and milling. Our company introduces that due to the different characteristics of stainless steel best drill bits for metal and other materials, the adhesion and fusion of stainless steel are particularly strong, and the chips will easily stick to the edge of the stainless steel best drill bits for metal, which increases the cutting conditions. Therefore, Noble Company I will give you an analysis of the correct use of best drill bits for metal stainless steel.
When milling stainless steel, the cutting edge must be sharp but also able to withstand the impact, and the chip pocket must be large. A large helix angle can be used. Best drill bits for metal (round nose best drill bits for metal, vertical best drill bits for metal) , The helix angle b is increased from 20° to 50° (gn=5°), and the tool durability can be increased by more than 2 times.
When milling stainless steel, use down milling as much as possible. The asymmetric down milling method can ensure that the cutting edge is smoothly cut away from the metal, and the chip bonding contact area is small, and it is easy to be thrown off under the action of high-speed centrifugal force, so as to prevent the chip from impacting the rake face when the cutter tooth re-cuts into the workpiece The phenomenon of spalling and chipping improves the durability of the tool.
Therefore, it should be used according to the stainless steel milling cutter corresponding to different materials!
The key points for smooth processing of stainless steel are:
(1) Control the cutting resistance at a low level;
(2) Avoid burden with the tip of the knife;
(3) Feed and depth of cut should not be too small.
The above is the introduction of our company on the correct processing of stainless steel milling cutters. I hope it will be helpful to everyone.
