hat do you do with the auto knife
adjust the position of the small stiffness of the spindle vibration system to make it in the normal direction on the surface of the cutting force F and processing Angle range, such as boring when using cutting flat boring bar, car cylindrical, turning the pack. By changing the amount of cutting and the geometrical shape of the tool, the overlap coefficient is reduced, such as using the right Angle. It reduces the cutting speed and increases the Angle of the cutting, the main Angle and the front Angle. To increase the cutting rate properly; Improve the processability of processed materials. Increasing the damping of the cutting; Reduce the back Angle of the cutter properly; To sharpen the edge of the back knife; Properly enlarging the edge of the drill bit; Make the tip of the knife well above (the outer circle) and lower the center line of the workpiece to obtain the lower Angle. To reduce the high frequency vibration of the cutter, the rear Angle and the front Angle of the cutter should be enlarged
Turning process - a fine car has a few main aspects: The outer circle fine car is mainly used to look at the Angle of the blade, feed (Fn), cut depth (Ap), cutter main Angle, blade ISO shape (C, D, T, etc.) 2, except the attention of the inner circle treatment above, note also suspended, length to diameter ratio (L/D) best don't more than 3 to 4 times the diameter, and the main Angle is best close to 90 °, the closer it gets to the main force the smaller the Angle, the smaller the vibration trend. Three basic should not have too big relationship, machine tools, unless the tool says some are ruled out, mainly cylindrical cannot guarantee accuracy, can be worn screw or have a home, but the basic can be ruled out machine tool vibration problems, are rare
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
