How is the rough lathe of CNC lathe and the fine lathe tool divided?
In the case of steel, the blade of a coarse car is a member of RN, the slot of a semi-fine car is MN, the blade of the fine car is a FN, and the superfine car is a slot type FF. The depth of the thick car is 2-12mm, the depth of the fine car is 0.2-2mm and the depth of the superfine car is usually 0.05 to 0.8 mm.
The following terms should be familiar if you are familiar with every Angle of the car knife: Front Angle: the Angle of the cart is smaller and the car is larger. Rear Angle: the rougher Angle is smaller (6-8 degrees) and the fine car is larger (10-12 degrees). Tip Angle: when a rough car is usually 5 degrees, it will be 10 or larger when it is large. In fine cars, the average is -4 degrees. Main Angle: according to machine tool - workpiece - tool system stiffness choice. Side Angle: according to surface roughness choice, high time Angle is smaller. Radius of the tip of the blade: generally hard alloy tool, r = 0.5-2mm, and small when rough. You can do the same with the above data sharpener
For aluminum alloy, the slot type of semi-fine car is GP, the blade slot of the fine car is ms-f, and the superfine car slot is ms-e. The depth of the semi-fine car is about 0.5 to 5 mm, the depth of the fine car is 0.2-2mm and the depth of the superfine car is 0.16-1mm. The semi-fine car USES the KC5410 (coating carbide) blade, the fine car USES the KD100 (PCD) blade, the super fine car USES the KD1415 (PCD) material blade; For low-silica aluminum, which contains less than 12.2% of silicon, the KC5410 has a cutting speed of 250-1000m/min, and KD100's cutting speed of 400-2500 m/min. For high-silicon aluminum, which contains more than 12.2% of silicon, the speed of the KD100 is 300 to 800 meters per minute, while KD1415 has a cutting speed of 350 to 1200 meters per minute.
