What are the common problems that may occur during lathe parts processing and what are their solutions?

The lathe parts processing size out of tolerance may be caused by inaccurate tool setting, incorrect compensation setting, tool wear or looseness, thermal expansion and other factors. The solution includes careful tool setting to ensure that the tool compensation value is accurate; regularly check the tool wear, pay attention to temperature changes during processing, and make dimensional compensation when necessary.
Poor surface finish is usually caused by tool wear, improper cutting parameters (such as too fast cutting speed or too large feed), insufficient cooling or unstable tool installation. It can be improved by timely replacement or grinding of tools, adjusting cutting parameters, appropriately reducing cutting speed and feed, ensuring adequate cooling, and ensuring that the tool is firmly installed.
Lathe parts processing processing vibration may be caused by loose clamping of tools or workpieces, loose spindles or tool holders, unreasonable cutting parameters, and insufficient rigidity of the equipment itself. The solution is to check the clamping stability of the workpiece and tool, ensure that the spindle and tool holder are tight, reasonably adjust the cutting parameters, and improve the rigidity of the equipment.
Workpiece bending or taper may be caused by misalignment of the tailstock and spindle, incorrect tool installation angle, deformation of the turning tool or loose tailstock. The solution is to adjust the alignment of the tailstock and the spindle, ensure that the tool is installed correctly, use a more stable tool, and avoid loose tailstock.
Lathe parts processing tool wear or frequent tool breakage may be caused by unreasonable cutting parameters, tool material and workpiece mismatch, insufficient cooling or hard processing material. The solution is to reasonably adjust the cutting parameters, select tools suitable for the workpiece material, improve the cooling effect, and reduce the processing speed if necessary.
Spindle overheating or abnormal noise may be caused by insufficient spindle lubrication, bearing damage or improper clearance, excessive cutting load, and insufficient cooling. The solution is to regularly check and replenish the spindle lubricant, check the bearing condition and adjust the clearance, reasonably distribute the cutting load, and ensure sufficient coolant.
Insufficient or interrupted cutting fluid may be caused by blockage of the coolant pipeline, failure of the cooling pump, poor coolant quality or improper setting of the cooling system. The solution is to check the cooling system, clean the blocked parts, ensure sufficient coolant flow, and regularly check the cooling pump and coolant quality.
