CNC Flat Bed Lathe turning accuracy instability solution?

CNC Flat Bed Lathe turning accuracy instability solution?

What is the cause of unstable turning accuracy of CNC Flat Bed Lathe?

CNC Flat Bed Lathe is mainly used for processing various precision parts, but sometimes there is unstable processing accuracy, what is the reason for this? According to experience, CNC Flat Bed Lathe manufacturers summarized 9 kinds of reasons and corresponding solutions, hope it will be helpful to you.

1.The driving phase light works normally, while the size of the processed workpiece is not the same size.

Failure causes: the CNC Flat Bed Lathe dragging plate runs at high speed for a long time, causing the screw rod and bearing to wear; the tool holder deviates from the repeat positioning accuracy when it is used for a long time; the dragging plate can return to the starting point of processing precisely every time, but the size of the processed workpiece still changes. This phenomenon is generally caused by the spindle, which is rotating at high speed and the bearing is worn out seriously, resulting in the change of machining size.

CNC Flat Bed Lathe manufacturer’s method: lean the percentage table against the bottom of the tool holder, while editing a set of fixed cycle program through the system, check the repeat positioning accuracy of the dragging plate, adjust the screw clearance and replace the bearing; check the repeat positioning accuracy of the tool holder with the percentage table, adjust the machinery or replace the tool holder; check the accuracy of returning to the starting point of the program after machining with the percentage table, if it is possible, overhaul the spindle and replace the bearing.

2.the workpiece size is accurate, the surface finish is poor.

Failure causes: tool head is damaged and not sharp; CNC Flat Bed Lathe produces resonance and is not smoothly placed; crawling phenomenon occurs in the machine tool; poor processing technology.

CNC Flat Bed Lathe manufacturer’s solution: the tool is worn or damaged and not sharp, re-sharpen the tool or choose a better tool to re-pair the tool; the machine tool produces vibration or is not placed smoothly, adjust the level, bottoming out and fixing smoothly; the mechanical crawling is due to the trailer guide being worn seriously, the screw ball is worn or loose, the machine tool should pay attention to maintenance, the wire should be cleaned up during the up and down shift, and lubricant should be added in time to reduce friction; choose the suitable workpiece processing of coolant, in the case of other processes can meet the processing requirements, try to choose a high spindle speed.

3.the workpiece produces taper size head phenomenon.

Failure causes: the machine tool is not adjusted to put the level, a high and a low, put put unstable; when turning long axis, the material required is hard, the tool eats the tool deeper, causing the phenomenon of letting the tool; the tailstock and spindle are not consistent.

CNC Flat Bed Lathe manufacturer’s solution: adjust the level of the machine tool with a level meter, lay a firm foundation, fix the CNC Flat Bed Lathe and improve its toughness; choose a reasonable machining process to avoid excessive force on the tool and adjust the tailstock.
