Principles of CNC machining process division

Precision Parts Are Composed Of Multiple Surfaces With Different Structures. Each Surface Of The Parts Has Different Precision Requirements, Each Surface Has Corresponding Precision Requirements. Therefore, When Performing CNC Processing , In Order To Achieve The Precision Requirements Of The Part Design, We Should Follow Certain Processing Process Principles.

1. The Principle Of Roughing First Then Finishing: Firstly, The Material Is Rough-Machined To Form The Product Shape. Then, Each Surface Of The Product Is Processed According To The Steps Of Rough Machining → Semi-Finishing → Finishing, So As To Gradually Improve The Surface Accuracy Surface Smoothness Of The Parts.

2. The Principle Of Machining The Reference Surface First; When Machining Parts, The Reference Surface For Finishing Will Be Machined Out, Because The Positioning Reference Is Accurate The Workpiece Clamping Error Is Small. Therefore, When Machining Parts, The Reference Surface Will Be Machined Out First As A Reference. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotation. If There Are Multiple Reference Surfaces, They Will Be Processed According To The Order Of Reference Conversion The Principle Of Gradually Improving Machining Accuracy.

3. The Principle Of Machining The Surface First Then The Hole: For Parts With Relatively Large Plane Contour Dimensions, Such As Machine Bodies, Boxes, Brackets Other Parts, Plane Positioning Is More Stable Reliable, Can Avoid Processing Errors, So The Principle Of Machining The Surface First Then The Hole Is Adopted.

4. The Principle Of Processing The Inside First The Outside Second Is Mainly For Precision Copper Sleeve Parts. Because The Coaxiality Of The Outer Circle The Inner Hole Of Copper Sleeve Parts Is Required To Be Higher, The Inner Hole Is Processed First With The Outer Circle As The Processing Reference, Then The Outer Circle Is Processed With The Inner Hole As The Processing Reference. This Can Highly Guarantee The Coaxiality Of The Two Simplify The Clamping Tools.

Reduce The Number Of Tool Changes During CNC Machining. The Order Of Tool Use Should Be Arranged Before Machining To Avoid Machining Errors. Huiwen Has Long Been Committed To The Processing Of High-Precision, Difficult, Easily Deformed Metal Plastic Parts , Small Medium-Volume Production Of Light Alloy Composite Material Parts (Such As Aluminum Alloy, Carbon Fiber, Etc.),  Procurement Customization Of Robot Parts .
