How to improve the accuracy of the CNC machining center surface?
CNC machining centers can process a wide variety of workpieces,whether flat or curved,but they often have problems that bother us,affecting the quality of the workpieces.For example,the accuracy of the surface is not high.How to solve it?
First of all,we need to find out the reason why the surface accuracy is not high,and then proceed to solve it.The Jiexiang CNC machining center first tells you the possible reasons:
1.The cutting parameters are unreasonable,and the surface of the workpiece surface is rough.
2.The cutting edge of the tool is not sharp.
3.The tool is too long and the blade is too long.
4,chip removal,blowing,oil is not good.
5,programming the way of the knife,(you can consider taking the down milling as much as possible).
6,the workpiece has burrs.
The above is the reason for the low accuracy of the CNC machining center surface.For these reasons,we can take the following measures to improve:
1.Cutting parameters,tolerances,margins,and speed feed settings should be reasonable.
2.The tool requires the operator to check from time to time and replace it irregularly.
3.When the tool is clamped,the operator is required to clamp as short as possible,and the blade should not be too long.
4,for the flat knife,R knife,round nose knife undercut,the speed feed setting should be reasonable.
5,the workpiece has burrs:the root of our machine tools,tools,the way of the knife has a direct relationship.So we need to understand the performance of the machine and make a knife for the burr.
The above is the reason analysis and improvement method for the surface accuracy of CNC machining center is not high.There are still many common problems,such as overcutting the workpiece,correcting the knife,etc.To solve these problems,use the above method to find out the cause and then find a solution.
