| Vibration occurs during cuttingMotion and ripple | (1) Check whether the rigidity of the system is sufficient, whether the workpiece and tool bar extend too long, whether the spindle bearing is properly adjusted, whether the blade is firmly clamped, etc. (2) Reduce or increase the spindle speed of the first to second gear for trial processing, and choose the number of revolutions to avoid ripples. (3) For non-coated blades, if the cutting edge has not been strengthened, the cutting edge can be lightly ground with fine oil stone (in the direction of the cutting edge) on site. Or after processing several workpieces on the new cutting edge, the ripples can be reduced or eliminated. |
| The blade wears quickly and the durability is very low | (1) Check whether the cutting amount is selected too high, especially whether the cutting speed and cutting depth are too high. And make adjustments. (2) Whether the coolant is not supplied enough. (3) Cutting squeezes the cutting edge, causing slight chipping and increasing tool wear. (4) The blade is not firmly clamped or loosened during the cutting process. (5) The quality of the blade itself. |
| Large pieces of blade chippingOr chipped | (1) Whether there are chips or hard particles in the blade groove, cracks or stress have been generated during clamping. (2) Chips entangle and break the blade during the cutting process. (3) The blade was accidentally collided during the cutting process. (4) The subsequent chipping of the threaded blade is caused by the pre-cutting of the cutting tool such as the scrap knife. (5) When the machine tool with retracted tool is operated by hand, when retracted several times, the blade load suddenly increases due to the slow retracting action of the subsequent times. (6) The material of the workpiece is uneven or the workability is poor. (7) The quality of the blade itself. |
