Generally speaking, there are several reasons for the occurrence of knife marks: 1. The lathe spindle is loose; 2. The clutch clearance is large; 3. The tool holder or the pallet 

clearance is large; Thin and larger disk workpieces; 5. The tool is blunt, the tube wall is thin and the workpiece is long, and the tool rod is too long; 6. The clearance of the 

coordinate axis needs to be adjusted; 7. The tool is higher than the axis, etc., and the lathe is preferred in various cases The strength of the system and workpiece.

The treatment method of insert pattern

First, confirm the clamping of the workpiece (whether the clamping force of the chuck is too small) and whether the turning tool is fixed on the turret.

Secondly, confirm the fixing condition of the turret (whether it is during processing. Check whether there is any problem with the clearance of the spindle or the clearance 

of the ball screw. The clamping should be as short as possible, and the insert rod should be as short and thick as possible to increase rigidity. Sharpen it.

It is also necessary to change the processing parameters, reduce the speed or increase the feed, which needs to be within the suitable range of the tool.

During finishing machining, the cutter head should not be too sharp, and the cutter head should have R so that the insert lines on the surface of the processed workpiece 

are not too obvious. If there is no cutter at all, it must be ground and polished or processed on a grinding machine.
