How to solve the problem of engraving machine cutting knife?

When we use the engraving machine, often encountered in processing engineering frequent cutting knife, affect our normal use. What is the cause of frequent cutting knife? How to solve the problem of engraving machine cutting knife? Engraving machine cutting knife actually the problem is the stress of the cutting tool has changed some influence factors of excessive or itself. There are seven reasons affecting engraving machine cutting knife, including, cutting tools, materials, machine, process, the neighboring environment, control system and auxiliary equipment. 1, carving machine tools: cutting tools of hardness, the strength of the cutting tool, cutting tool sharpness, and it is particularly important tool stretched out the length of the cutting tool rake face is smooth. ( 1) Tool hardness related with coating material, cutting tool material grain number itself, micro geometry Angle cutter. ( 2) The strength of the cutting tool of factors associated with the cutting tool material itself, the influence of alloy elements. ( 3) The influence of cutting tool sharpness with cutter grinding, grain number of grinding wheel used, cutting tool's own grain number, rake Angle and back Angle degree. 2, carving machine material: materials related materials whether have impurities, the hardness of material is too big. 3, engraving machine, machine tools, machine tools related factor is what we choose whether appropriate, this material is not suitable for processing, machine tool is played, not play level is likely to cause cutting knife. Spindle motor speed is too low, the spindle motor speed is too low, each tooth each turn turning is bigger, the cutting force is bigger, so it could cause cutting knife, in general, we use the spindle speed is still on the high side some good. 4, carving machine process: process, machining allowance is the unreasonable, is there a ladder-like allowance, which there will be changes when processing of cutting force caused by vibration, lead to broken knife, so it is necessary to increase semi-finishing. Another is turning is too large. And many other factors in the process, of course, here is not much said. 5, the neighboring environment: the neighboring environment factors around the source, provided by the voltage is stable. 6, control system, control system related factors whether the path smoothing, priority mode is correct, it directly affect the start-up speed of machine and start the speed more work more prone to vibrate, thus easy to cause the cutting knife. 7, auxiliary equipment, auxiliary equipment related factors have clearance whether smooth, whether to avoid the secondary cutting, more important is the problem of the knife. Engraving machine tool and clamp head to see if there is dirt, knife on the strength is too big. Chuck and nut is in good condition. Tool out quantity is big, it is very important. How to solve the problem of engraving machine cutting knife? In the process of engraving machine processing work if there is a broken knife, need analysis from these aspects, combined with the actual situation, find the cause of the cutting knife, precision processing and then take corresponding measures.
