Possible problems and solutions in the production of stainless steel turned parts

In the production of stainless steel turned parts, various problems may arise. It is common to have problems in the production of stainless steel turned parts. So how to solve these problems in the production of stainless steel turned parts?

Gnawing knife

Failure analysis and solution: The reason is that the turning tool is installed too high or too low, the workpiece is not clamped firmly or the turning tool is worn too much.

1. The turning tool for the production of stainless steel turning parts is installed too high or too low. If it is too high, the flank of the turning tool will resist the workpiece to a certain depth, increasing the friction, and even bending the stainless steel turning parts, causing the phenomenon of gnawing; if it is too low, the chips will not be easily discharged, and the turning tool The direction of the radial force is the center of the workpiece, and the gap between the traverse lead screw and the nut is too large, which causes the depth of the tool to be continuously and automatically deepened so that the stainless steel turning parts is lifted and the tool is gnawed. At this time, the height of the turning tool should be adjusted in time to make the tip of the tool equal to the axis of the workpiece (the tip of the tailstock can be used for tool setting).

2. The clamping of stainless steel turning parts is not secure. The rigidity of the stainless steel turning parts itself cannot withstand the cutting force during turning, so excessive deflection is generated, which changes the center height of the turning tool and the stainless steel turning parts, resulting in a sudden increase in the cutting depth, and the biting of the tool occurs. At this time, stainless steel should be used. The turning parts are firmly clamped, and the tailstock center can be used to increase the rigidity of the stainless steel turning parts.

3. Excessive wear of the turning tool causes an increase in the cutting force, bending of the stainless steel turning parts, and tool gnawing. The turning tool should be reground at this time.

Rough thread surface

Failure analysis and solution: The reason is that the cutting edge of the turning tool ofstainless steel turning parts is not polished and clean, the cutting fluid is not suitable, the cutting speed and the workpiece material of the stainless steel turning parts are not suitable, and the vibration during the cutting process is successful. The solution is: Correctly dress the grinding wheel or use oilstone to finely grind the tool for cutting stainless steel turning parts; select the appropriate speed and cutting fluid for cutting stainless steel turning parts; adjust the lathe bed saddle pressure plate and the inserts of the small and medium slide dovetail guide rails to ensure that each The accuracy of the guideway gap prevents vibration when cutting stainless steel turning parts.

In short, there are many types of failures when turning the thread of stainless steel turning parts. There are equipment reasons, tools, stainless steel turning parts, operators, etc. When troubleshooting, it is necessary to analyze the specific conditions and pass the production of stainless steel. Various detection and diagnosis methods for turning parts equipment, find out specific influencing factors and adopt effective solutions.
