What kind of car knife does the car harden steel? After quenching, the deformation is large and needs to be trimmed
Have time to talk. You're still going to use the boron nitride. It's time for 2mm to grind the bed. You give me the details. Let me analyze it for you. Contact information in the data.
This is the cutting edge of the tool and the whole CBN! I am also a knife, interested to contact me, my personal data has contact information! Welcome to harass
For the cause and countermeasures of the boron blade collapse, see the reference material "the shallow view of the CBN blade". I have also met before, according to your processing allowance, it is better to choose the domestic quality of the better cubic boron n. At present domestic do boron nitride tool manufacturers are mostly foreign CBN composite plate made by made of CBN tool cutting, welding, complex brand characteristics of CBN abroad is not very clear, this is also the domestic composite superhard predicament of the market
Boron oxide Cubic boron oxide (CBN) is the promotion materials in recent years, the hardness and wear resistance is second only to diamond, the cutter is suitable for machining hard and wear resistance of iron alloy and nickel base alloy, cobalt base alloy. The tool can be divided into outer circle, shoulder, end face, cutting, cutting, thread and forming tool. There are also car knives for automatic line and digital control machine tools. Cutting tool Cutting tool was narrow and deep slot, cutting chip space is little, chip easy to jam, in order to reduce with friction on the surface of the finished, the both sides of the cutting part must have a grinding Angle, thus the strength of the root is greatly weakened. In addition, cutting the cutting speed to zero is not good for cutting. Therefore, cutting off the car knife is very easy to "hit the knife" in the work. Advanced cutting tool generally will be the main cutting edge into a herringbone, ground to a roof in front of the form, make the chip produces lateral contraction, in one direction steadily, from blocking in the trough, then at the bottom of the cutting tools made of protruding abdomen form at the same time, in order to maximize the strength and stiffness (figure 3).
The shape of the lathe tool in the frame of the lathe tool is flat, the shape and the circle 3 (figure 4). The shape of a lathe blade is the same as the cut of the piece of the piece of the piece of the piece of the piece of the piece. The antlers are slightly different when they are not zero, and they have to be calculated or graphically to figure out the cut of the lathe. The automatic line and CNC machine tool should be used for the special request: the cutting performance is reliable, the broken chip is stable, the cutter can be replaced quickly. As a result, the quality of the blades is higher, and the use of the knife is mandatory to avoid excessive wear and tear. The shape and size of the chip shavings must be determined according to the working conditions, so that the cuttings form a short arc of fragmentation. In order to reduce the time of the change of the knife and adjustment, the adjustment of the tool applies various types of tools to the tool or to the machine. Figure 5 is the use of screws or wedges to adjust the radial dimension of the tool, the automatic line and the digital control machine tool with the tool of the diameter W and the tip height H.
