How to extend the use time of chemical fiber cutter？

The processing of Chemical Fiber Cutting Knifes, a large amount of cutting heat is generally generated on the chips. If the length of the chips can be controlled to ensure timely and effective chip breaking, this part of the cutting heat can be taken away by the chips, so chip breaking is to control the cutting temperature. an effective way. When machining difficult-to-machine materials, in the rough machining process, under the premise that the rigidity of the machining system allows, it should be possible to make chips break during the entire machining process as much as possible. At the same time, use a cutting fluid with good sedimentation performance to discharge the chips, and do not allow the chips to rub against the surface of the workpiece. When mixed with water, it forms a stable clear solution.

For difficult-to-machine materials, choosing different cutting methods has great differences in the damage of Chemical Fiber Cutting Knifes. No matter which cutting method is chosen, the principle is the same, which is to reduce the cutting force and the temperature of the cutting zone as much as possible. The trochoidal cutting method can minimize the cutting area, so that the actual cutting wrap angle of the cutting fluid can be smaller, thereby prolonging the heat dissipation time of each tooth of the Chemical Fiber Cutting Knifes and reducing the cutting temperature; using the helical interpolation method can make each tooth cutting The amount is relatively uniform to avoid the cutting force being concentrated on a few teeth and accelerating the wear. This effect is more obvious at the corners; while the large feed cutting method is adopted, the smaller depth of cut and larger feed can effectively reduce Small cutting force results in less cutting heat and lower temperature in the processing area.

Properly controlling the cutting force and cutting speed of the long Chemical Fiber Cutting Knife is also one of the effective means to reduce the temperature of the processing area and prolong the service life of the cutting fluid. When processing difficult-to-machine materials, finely ground long chemical fiber knife edges are generally used, and the cutting depth and cutting width should not be too large. When choosing the cutting line speed, it should be considered according to factors such as different material types, part structure and processing equipment.
