I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?
My car operation for more than 8 years, according to your car parts, actually hit 600 on the coarse, fine car or 1600 rpm, finish good, cutting speed is not too fast, the general lathe is mid-range open 6 can, keep your car parts after.
LZ, I don't know if you did it for eight years or eight years. When you finish the car hit 1600 turn, your knife is a diamond? I'll ask you to open 6 is the number of mid-range lathe wire ah, the general lathe open open 6 mid-range at least twenty-six wire, when you finish turning with so high feed! Even if you use 1600 rpm and this knife, your surface is bright, but your workpiece roughness must be unqualified. Remember, finish is not roughness. You are good at the question. The cutting speed is based on what kind of cutting depth and amount of knife you choose when you rough the car. You don't say the exact size of the part you want to process. That's not good. The key experience is to rely on their own step by step, tired.
The hungry! For the 450--700 rpm, the most appropriate, because once you and I work almost, I use the 6140 machine, crude car to 450 rpm to 700 RPM fine car is good. If the surface quality is good, the blank is not much, you can use 450 turn into a knife, but the knife grinding......
The surface quality is good, the blank diameter is 50MM. Can play around eight hundred rpm.When the car is refined, 1200r/min

When the car is refined, 1200r/min.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron and non-ferrous metals.
