Whats the Common faults and solutions in turning parts ?

1, the thread surface is rough

Fault Analysis: The main cause of this problem is that the turning tool is not smooth enough, the cutting fluid, the cutting speed is not matched with the machining material, or the vibration generated during the cutting process.

Solution: Refine the tool with oil or grinding wheel, and select the matching cutting fluid and cutting speed to adjust the position of various parts to ensure the accuracy of the gap of each guide rail, thus preventing the vibration generated during cutting.

2, Turning tools are seriously worn

Fault analysis: mainly because the position of the turning tool is not correct, either too high or too low, and the workpiece clamping is not firm, Turning tools are seriously worn

Solution: Adjust the height of the turning tool so that the tool tip is at the same height as the axis of the workpiece

3, Thread pitch instability

Fault Analysis: The cause is that when the lead screw rotates for one week, the workpiece is not loaded with an integer.

Solution:

(1) The solution is to use the positive and negative method to retreat

(2) The threaded workpiece and the lead screw which are integral multiples of the screw pitch of the turning part and the tool-to-tool ratio are rotating. After lifting the opening and closing nut, at least the screw must be rotated one turn to reclose the opening and closing. The nut, so that when the lead screw rotates one turn, the workpiece turns an integral multiple, and the turning tool can enter the spiral groove of the previous one, so there will be no disorder, so that the opening and closing nut can be used to manually retreat. Knife. This quick retraction is beneficial to increase productivity and maintain screw precision, while the lead screw is also safer.
