Q:How does a car knife grind to make a car clean: The blade is sharpened and the tip of the blade is fixed. You're not going to use the yg8 now. If it's yg8 you're too tired to come out clean! Yg8 is cast-iron.

Q:hat do you do with the auto knife: To adjust the cutting speed to avoid the critical cutting speed. When cutting, turning, or using wide blade cutter, forming tool and thread cutter, the speed of the machine is less than the critical cutting speed. The speed of cutting is greater than the critical cutting speed when the vertical and the cutting ring face are. It increases the stiffness of the process system and improves the vibration resistance. When the tool is installed, it should not be too long, and the boring tool is as short and thick as possible. Try to shorten the outstretched length of the socket. To remove the vibration by using a central frame or with a tool holder, or with a long, thin shaft cutter with a large Angle. It is possible to do as much as possible without the cutting speed of the product that is prone to produce the tumor. Use the appropriate cutting amount. The cutting width can be reduced and the cutting thickness is increased

Q:What's the difference between the iron and the aluminum: Are you a lathe worker? Is it the same in the front and back? Car after Angle distribution in the cross section of the former solution, when outside the circle is the normal point of view, loading Angle have influence, but a good sharpener Turner is the key, please don't change turning solution by loaded askew.

Q:How many blades are there for cutting off a car knife? Which is the main blade, which is the blade?: Chisel edge cutting front end is the main cutting edge, flanked by vice cutting edge, have to do is take down the tool of measuring.

Q:If you can make a simple machine tool, you can also improve your productivity.: You're very motivated and want to stick with it. My family has been doing a car knife for decades, mainly welding knives. The fact that welding knives still dominate the market share, especially in the developed world Up to 70 per cent of those machines have a very low share of the knife.

Q:Kneel for the difference between the blade and the edge of the blade.: Negative chamfer is in front of the positive rake Angle along the cutting knife surface grinding width is small, the forefoot gamma 08 or less chamfer surface, its role is to enhance a cutting edge, especially to the poor impact toughness of props material, reduces the props along the cutting vibration free edges is broken in the blade surface grinding width is small, the Angle of alpha < 08 chamfer surface, enhances the tool squeeze damping effect, help to eliminate the low frequency vibration in the process of cutting.

Q:The same car knife, how to realize the rough car processing wood or steel parts, please, thank you!: In fine cars, the speed is between 600 and 800. Go to basically 0.1 mm around, about the implementation of the thick fine car a knife, basically be you grind a knife, to want to grind a not too big also not too small arc. This ensures that the tip of the blade can be wear-resistant and can guarantee the surface smoothness of the car. Car wood, it's easy. You can grind it with a knife of a rough steel piece, no problem

Q:The long, thin axle, how to install the tool, and whether to aim at the center: Car, slender shaft turning point should be slightly higher than the center of the workpiece is 0.2 ~ 0.3 mm, because of the coordinate plane (cutting plane and reference plane) change, and make the rake Angle greaten, after Angle is smaller. And when there is a slight fraying in the back, there is a small amount of wear and tear that is equal to zero to prevent the vibration of the workpiece.

Q:The type of circular lathe tool of CNC lathe: According to the main inclination Angle points: there are 95 degrees (for semi-finishing and finish machining of cylindrical and face), 45 degrees (for cylindrical and end face, it is mainly used for rough turning), 75 - degree cylindrical (mainly used for coarse car) and 93 degrees (mainly used for contour machining), 90 degrees (for cylindrical coarse fine cutting).

Q:What type of car can be made of the car with a smooth surface: The normal T15 is OK, mainly the Angle of grinding knife and the surface finish of the blade
