Hello, I ask you a question, how much of an Angle will you wear with a white steel knife?
Speed is too high to copper don't hit such a high speed car ~ can't add cutting fluid to high speed machining copper knife grinding hard ~ hot knife fast easy to wear, you wear white steel knife to sharpen some additionally, feed is generally based on material and rotating speed, but have a roughly the speed, the iron material generally around 100-800, around 700-800 in copper and aluminum has the highest speed, 2000 turn can, cast iron in 100-300 turn around, the adjustment of the feeding speed is the speed and feed rate ~ are generally from experience, I do the lathe work more than 4 years, how much I haven't seen feeding speed, only know a living and feed quantity and speed. Copper can be a little bit bigger, but the knife is worn as short as possible, if I give you a knife in your 20 minutes
Use the alloy knife, do not use the groove, the lacquer face on the knife is worn down and I can process the copper material basically a knife can process 2000 pieces to grind a knife
The wear of the car should increase the Angle of the knife, and also open the u-groove on the main cutting edge
