CNC lathes are mainly used to process various precision components, but occasionally there may be unstable machining accuracy. So, what is the reason for this? How can we solve such situations?

The so-called dimensional accuracy mainly refers to the degree to which the dimensions of the workpiece after machining the parts are in line with the requirements of the drawing. Therefore, in order to improve the dimensional accuracy of the parts in CNC machine operation, it is necessary to pay attention to the operating skills in CNC machine operation, common control methods for the dimensional accuracy of the parts, such as accurate tool alignment, adjustment of tool wear compensation, and modification of the dimensional control accuracy in the program, The size of the workpiece produced in this way can be precise.

1. Crawling occurs in CNC lathes

The main reason for the crawling of the equipment is that the drag plate guide rail is severely worn, and the screw and ball bearings are worn or loose. Solution: Daily attention should be paid to the maintenance of CNC lathes. After the work is completed, attention should be paid to cleaning the iron wires and adding lubricating oil in a timely manner to reduce friction.

2. Resonance and unstable placement of CNC lathes

It is necessary to choose a stable position on the ground to place the CNC lathe, pay attention to adjusting the angle, and ensure stable fixation.

3. Poor processing technology

Choose a suitable coolant for workpiece processing, and choose a higher spindle speed as much as possible while meeting the processing requirements of other processes, so that the processed parts will be particularly smooth.

4. Damaged blade tip or tool not sharp

If the tool is worn or damaged and not sharp, it needs to be re sharpened or a better tool needs to be selected for sharpening.

5. The speed of rapid positioning is fast, and the motor and drive cannot react, resulting in unstable machining dimensions

If the fast positioning speed is fast, it is necessary to adjust the speed, cutting speed, and time appropriately to ensure that the driver and motor operate normally at the rated operating frequency.

6. The prolonged high-speed operation of the drag plate results in wear of the screw and bearings

A dial gauge can be used to lean against the bottom of the tool holder, and a fixed cycle program can be edited by the system to check the repeated positioning accuracy of the drag plate of the CNC lathe equipment, adjust the gap between the screw rods, and replace the bearings.
