First, in the feed mechanism to adjust to improve the machining accuracy of CNC lathe
First, in the ball screw guide error caused by the CNC lathe machining accuracy is affected, in this regard, the main factor is the pulse, so in the manufacturing ball screw program, to minimize the error caused by the impact of the pulse on the CNC lathe machining accuracy.
Second, in the feed mechanism gap for CNC lathe machining accuracy, which is mainly due to the problems in the components of its transmission machinery and lead to the impact, thus reducing the precision of runaway lathe processing. The main components are the gears, connecting joints, ball screws and the supporting shaft. Problems between these components will affect the accuracy of CNC machine tools, so we need to strengthen the connectivity between their structures. The precision between them will affect the precision of lathe processing, thus reducing the gap between each structure and strengthening the tightness between each structure will improve the precision of CNC lathe processing.
Second, the impact of the error in the programming
The difference between CNC lathe and ordinary lathe lies in the different precision of the parts, but the error that appears in the programming process can be minimized, which requires us to reduce the error from several aspects, so as to improve the precision of CNC lathe machining.
The first one is the impact on the accuracy of the lathe due to the interpolation error. So try to adopt certain ways to reduce the problems that occur in programming, using absolute way programming, and there can eliminate the error is to use the insertion will reference point quality for programming in the program.
Second, the impact of approximation error on the final accuracy. Since there is the use of approximation in the process so that there will be errors. So try to master the contour equation to program will largely reduce the error, so that the impact on the accuracy of CNC lathe machining can be eliminated;.
Thirdly, the influence of rounding error in the programming process reduces the machining accuracy of CNC lathe, so we should choose the minimum value of linear displacement determined by the pulse equivalent for reference when processing. So when programming, we have to work strictly in accordance with the specifications above the drawing as the reference.
