After the hardware is processed, the workpiece size is accurate and the surface finish is poor.The cause of the failure: the cutter tip of the machine tool is damaged, not sharp; the machine tool generates resonance, the placement is not stable; the machine tool has crawling phenomenon; the processing technology is not good.Solution: If the tool is not sharp after being worn or damaged, re-grind the knife or choose a better tool to re-align the tool; the machine will generate resonance or place it is not stable, adjust the level, lay the foundation, and fix it smoothly; the reason for the mechanical creep is drag The guide rail of the plate is very worn, the screw of the lead screw is worn or loose, and the machine should pay attention to maintenance. After the work, the wire should be cleaned and the lubricant should be added in time to reduce the friction. The coolant suitable for the workpiece processing can be selected to meet the processing requirements of other processes. In the case, try to use a higher spindle speed.
B. Unstable dimensional changes caused by cnc machine equipment systemsThe cause of the fault: the system parameter setting is unreasonable; the working voltage is unstable; the system is subject to external interference, causing the system to lose synchronization; the capacitor is added, but the impedance between the system and the driver does not match, resulting in loss of useful signal; signal between the system and the driver The transmission is not normal; the system is damaged or internal.Solution: speed, acceleration time is too large, spindle speed, cutting speed is reasonable, whether the operator's parameter modification causes system performance change; install voltage regulator equipment; ground wire and determine that the connection is reliable, the driver pulse output contact Add anti-interference absorption capacitor; select the appropriate capacitor model; check whether the signal connection between the system and the driver is shielded, whether the connection is reliable, check whether the system pulse signal is lost or increased; send the factory to repair or replace the motherboard
