Different Processes May Have Different Advantages In Different Application Fields. The Main Factors That Influence The Performance Of Products Are Process, Material And Use. So, What Are The Elegant Processing Of Slow Walking Silk? Let'S Take A Look At The Introduction Below.

What Are The Exquisite Processing Of Slow Silk

(1) Select Appropriate Mold Materials

Slow Wire Processing Is Generally Carried Out After Billet Hardening. If Carbon Tool Steel Such As T8a And T10a Is Used, The Hardening Layer May Be Worn Off And The Hardness Will Be Significantly Reduced After Use And Grinding Because It Is Difficult To Quench And The Hardening Layer Is Shallow. In Order To Improve The Service Life And Processing Accuracy Of Wire-Cut Molds, Alloy Tool Steel Or Hard Alloy With Good Hardenability Should Be Selected To Make Them, And The Hardness Of These Materials From The Surface To The Center Has Not Been Significantly Reduced.

(2) Improve The Precision Of Mechanical Transmission

The Precision Of Mechanical Transmission Has Great Influence On The Machining Precision. The Displacement Precision Of The Table And The Motion Precision Of The Electrode Wire Directly Affect The Machining Precision. Because The Movement Of The Table Is Driven By A Plurality Of Transmission Pairs, Such As Gear Pairs, Screw Nut Pairs, Etc., Their Transmission Accuracy Directly Affects The Machining Accuracy. The Motion Precision Of The Electrode Wire Is Greatly Affected By The Rotary Precision Of The Guide Wheel, The Uneven Wear Of The Guide Wheel And The Relaxation Of The Electrode Wire. It Can Be Seen That The Mechanical Transmission Precision Is Not High On The Processing Quality Has A Greater Impact.

(3) Reduce Residual Stress

When Machining With Wire Cutting, Large Pieces Of Metal Will Be Cut Off, And The Relative Equilibrium State Of Residual Stress Inside The Material Will Be Damaged, And The Stress Will Be Redistributed. The Residual Stress In The Material Is Sometimes More Serious Than The Influence Of Machine Tool Accuracy And Other Factors On The Machining Accuracy, So That The Deformation Can Reach The Macroscopic Visible Degree, Even In The Cutting Process Of The Material Will Crack. In Order To Reduce The Deformation Caused By Residual Stress, Corresponding Measures Should Be Taken, Such As The Correct Selection Of Heat Treatment Specifications; Workpiece Contour Should Be Away From The Billet Edge 8-100mm; Before Wire Cutting, Aging Treatment Can Be Carried Out; Premachining Before Quenching To Remove A Large Part Of The Surplus; For Wire Cutting, The Second Cutting Method Is Used, The First Rough Cutting Hole, When The Stress Reaches A New Balance, Then Fine Cutting Hole; Select The Correct Cutting Sequence, Etc. The Above Measures Are Very Good For Reducing The Residual Stress In The Material.

(4) Reduce The Surface Roughness

The Surface Roughness Of The Mold Cavity Has A Great Influence On The Quality Of The Plastic Parts, And The Surface Roughness Should Be Reduced In The Cutting Process. Therefore, Relevant Measures Should Be Taken, Such As The Electrode Wire Tension Is Not Enough, Should Be Tensioned At Any Time; Feed Speed Should Be Adjusted Properly To Avoid Speed Fluctuation; Too Large Mechanical Transmission Clearance Is Also Easy To Make The Electrode Wire Shaking, So That The Coarse Roughness Is Increased, So It Is Necessary To Adjust The Tightness Of Each Mechanical Transmission Part In Time; Correct Selection Of Electrical Parameters To Avoid Excessive Single Pulse. In Addition, The Speed Of Wire Running Or Dithering Will Also Affect The Surface Roughness Of The Parts. They Are Not Conducive To Quality Improvement.
