Using Imported Multi-Axis Milling Machines, We Can Guarantee CNC Milled Parts With Tolerances Within +/- 0.01mm, While Also Maintaining Critical Dimensions Within +/- 0.005mm. Our Team Also Has Extensive Experience In Precision Parts Manufacturing For The World's Most Demanding Industries, Including Aerospace Medical. The 5-Axis CNC Milling Machine Is Equipped With An On-Site Detection System That Allows Us To Monitor The Actual Dimensions Of The Part During The Milling Process. The Computer Is Able To Automatically Adjust The Program Parameters To Ensure That The Part Is Manufactured Correctly.

In The Actual Processing Production Process, There Are Five Main Factors That Affect The Processing Accuracy.

　　1. The Machine Tool Is Heated Up

　　During Operation, The CNC Machine Tool Itself Will Generate A Certain Amount Of Heat. Factors Such As Motor Operation Component Friction Will Cause The Temperature Of The Machine Tool To Continue To Rise, Causing Components Structural Systems To Be Adversely Affected By Thermal Forces, Such As Tool Displacement, Parts Wear, Thermal Expansion Of Components, Circuit Burning, Etc., Which Will Reduce The Processing Accuracy Of Parts. In Addition, Most Machine Tools Are Installed In Unventilated Places With Limited Heat Dissipation Conditions Other External Environmental Conditions, Which Will Also Cause The Temperature To Rise. This Will Increase The Burden On The Operation Of The Machine Tool Reduce The Accuracy Of Parts Processing . In Severe Cases, It May Cause Mechanical Failures, Which Will Directly Affect The Efficiency Quality Of CNC Processing Of Parts. Shenzhen Huiwen Intelligent Manufacturing Technology Co., Ltd. Excels In Precision Parts Processing  Has More Than 100 Processing Equipment. You Are Welcome To Contact Us By Phone Send Us Drawings For Evaluation.

　　2. Error Wear Of The Tool Itself

　　The Tool In The Machine Tool Is Also One Of The Parts To Be Processed. In Its Own Production Processing Process, There Are Geometric Errors That Affect The Accuracy Due To The Limitations Of Processing Conditions. During The Installation Of The Tool, Human Operation Will Also Affect The Processing Accuracy. During Use, Due To The Long-Term Contact Between The Tool The Workpiece, Deformation Caused By Friction High Temperature, Etc., The Tool Will Also Cause Varying Degrees Of Wear. Of Course, When The Wear Accumulates To A Certain Extent, It Will Also Have A Significant Impact On The CNC Processing Accuracy.

　　3. Processing Position Error

　　The Parts Of CNC Machine Tools Have Basic Error Requirements Such As Surface, Shape, Curvature, Relative Relationship, Etc. CNC Processing Must Meet The Design Requirements Of Parts Achieve The Performance Quality Requirements Of Processing. During The Machine Tool Processing Process, Affected By Various Factors Such As Transmission Parts, Rotary Shafts, Component Friction, There Are Deviations In The Accuracy Of Part Appearance, Size, Relative Relationship, Etc., Which Reduces The Accuracy Of Part Processing. For Example: During The Machine Tool Processing Process, An Error In The Swing Angle Of The Processing Axis Will Cause The Shape Of The Part To Deform, The Accuracy To Be Reduced, Even Cause The Parts To Be Scrapped In Batches, Causing Significant Economic Losses To The Company. Huiwen Intelligent Manufacturing Technology Has 15 Years Of Processing Experience, Profound Technical Accumulation Senior Technicians In The Industry. It Has Long Provided CNC Precision Processing With An Accuracy Of Up To ±0.01mm. It Supports The Processing Of Products Made Of Copper, Iron, Aluminum, Steel Various Plastic Materials, Can Be Customized According To Drawings Samples! Welcome Customers To Visit Us On Site!

　　4. Processing System Error

　　The Machining System Of A CNC Machine Tool Is The Part That Directly Implements Part Machining. It Is A Whole That Is Assembled In A Certain Way Multiple Subsystems Subcomponents Operates Together. The Operation Of Each Component Will Affect The Machining Accuracy Of The Entire Machining System. Therefore, System Errors Are Constantly Generated By Multiple Components During Installation Operation. The Only Way To Minimize The Errors Of The Machining System Is Through Technological Advancement Improvement Of Construction Progress.

　　5. Deformation Error

　　During The Long-Term Processing Use, CNC Machine Tools Will Be Affected By External Forces, Such As Clamping Force, Gravity, Friction, Etc., Which Will Cause Deformation, Loosening, Elastic Deformation, Displacement Other Deformation Phenomena In The Processing System Of The Machine Tool, Resulting In A Decrease In The Production Accuracy Production Efficiency Of The Machine Tool. Under The Influence Of External Forces, The Machine Tool Will Only Reduce The Accuracy Of Production Processing, But Also Cause Damage To The Machine Tool In Severe Cases, Affecting Its Service Life. Therefore, It Is Necessary To Pay Attention To The Study Of The Factors Affecting External Forces On CNC Machine Tools Reduce The Impact On Machine Tools.
