During CNC Machining, How Does Huiwen Solve The Error Caused By Tool Radial Runout?

During The CNC Cutting Process, There Are Many Reasons For Machining Errors. The Error Caused By The Radial Runout Of The Tool Is One Of The Important Factors. It Directly Affects The Minimum Shape Error That The Machine Tool Can Achieve Under Ideal Machining Conditions The Geometric Shape Accuracy Of The Machined Surface. In Actual Cutting, The Radial Runout Of The Tool Affects The Machining Accuracy, Surface Roughness, Uneven Tool Wear Cutting Process Characteristics Of Multi-Tooth Tools. The Larger The Radial Runout Of The Tool, The More Unstable The Machining State Of The Tool, The Greater The Impact On The Machining Effect. Let Huiwen Briefly Analyze It Below. When Encountering This Problem, How Do Huiwen Engineers Solve The Error Caused By The Radial Runout Of The Tool?

▌ Causes Of Radial Runout In CNC Machining

    Manufacturing Errors Of Tools Spindle Components, Clamping Errors That Cause Drift Eccentricity Between The Tool Axis The Ideal Rotation Axis Of The Spindle, As Well As Specific Processing Technology Tooling May All Cause Radial Runout Of CNC Milling Machine Tools During Processing.

1. The Impact Of The Radial Runout Of The Spindle Itself

    The Main Reasons For The Spindle Radial Runout Error Are The Coaxiality Error Of Each Spindle Journal, Various Errors Of The Bearing Itself, The Coaxiality Error Between The Bearings, The Spindle Deflection, Etc. The Influence Of These Factors On The Spindle Radial Rotation Accuracy Varies With The Processing Method. These Factors Are Formed During The Manufacturing Assembly Of Machine Tools, It Is Difficult For Machine Tool Operators To Avoid Their Influence. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience .

2. Impact Caused By Inconsistency Between CNC Machining Tool Center Spindle Rotation Center

    When The Tool Is Installed On The Spindle, If The Center Of The Tool Is Inconsistent With The Rotation Center Of The Spindle, The Radial Runout Of The Tool Will Inevitably Occur. The Specific Influencing Factors Include: The Fit Between The Tool The Chuck, Whether The Tool Installation Method Is Correct, The Quality Of The Tool Itself.

3. Impact Of Specific Processing Technology

    The Radial Runout Of The Tool During Machining Is Mainly Due To The Radial Cutting Force, Which Exacerbates The Radial Runout. The Radial Cutting Force Is The Radial Component Of The Total Cutting Force. It Will Cause The Workpiece To Bend Deform Produce Vibration During Machining. It Is The Main Component That Affects The Quality Of Workpiece Machining. It Is Mainly Affected By Factors Such As Cutting Amount, Tool Workpiece Material, Tool Geometry, Lubrication Method Machining Method.

▌ How To Reduce Radial Runout In CNC Processing Plants

    The Radial Runout Of The Tool During Machining Is Mainly Due To The Radial Cutting Force Which Aggravates The Radial Runout. Therefore, Reducing The Radial Cutting Force Is An Important Principle To Reduce Radial Runout. The Following Methods Can Be Used To Reduce Radial Runout:

1. Use Sharp Knives

    Choose A Larger Tool Rake Angle To Make The Tool Sharper To Reduce Cutting Force Vibration. Choose A Larger Tool Back Angle To Reduce The Friction Between The Main Back Face Of The Tool The Elastic Recovery Layer Of The Transition Surface Of The Workpiece, Thereby Reducing Vibration. However, The Rake Angle Back Angle Of The Tool Cannot Be Too Large, Otherwise It Will Lead To Insufficient Strength Heat Dissipation Area Of The Tool. Therefore, Different Tool Rake Angles Back Angles Should Be Selected According To Specific Conditions. Smaller Ones Can Be Used For Rough Machining, But Larger Ones Should Be Used To Reduce Radial Runout Of The Tool During Fine Machining To Make The Tool Sharper.

2. Use Strong Cutting Tools

    There Are Two Main Ways To Increase The Strength Of The Tool. One Is To Increase The Diameter Of The Tool Bar. Under The Same Radial Cutting Force, If The Tool Bar Diameter Increases By 20%, The Radial Runout Of The Tool Can Be Reduced By 50%. The Other Is To Reduce The Extension Length Of The Tool. The Greater The Extension Length Of The Tool, The Greater The Tool Deformation During Processing. During Processing, The Tool Is In A Constant State Of Change, The Radial Runout Of The Tool Will Change Continuously, Resulting In An Uneven Workpiece Surface. Similarly, If The Extension Length Of The Tool Is Reduced By 20%, The Radial Runout Of The Tool Will Also Be Reduced By 50%.

3. The Front Cutting Edge Of The Tool Should Be Smooth

    During Machining, A Smooth Front Cutting Edge Can Reduce The Friction Of The Chip On The Tool, Can Also Reduce The Cutting Force On The Tool, Thereby Reducing The Radial Runout Of The Tool.

4. Spindle Taper Chuck Cleaning

    The Spindle Taper Hole Chuck Should Be Clean Free Of Dust Debris Generated During Workpiece Processing. When Selecting Processing Tools, Try To Use Tools With Shorter Extension Lengths. When Cutting, The Force Should Be Reasonable Uniform, Too Large Too Small. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience. It Has A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Processing. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

5. The Amount Of Cutting Should Be Selected Reasonably

    If The Cutting Depth Is Too Small, Slippage Will Occur During Processing, Which Will Cause The Radial Runout Of The Tool To Change Continuously During Processing, Making The Processed Surface Uneven. If The Cutting Depth Is Too Large, The Cutting Force Will Increase Accordingly, Causing Large Deformation Of The Tool, Increasing The Radial Runout Of The Tool During Processing, Also Making The Processed Surface Uneven.

6. Use Up-Cut Milling For Finishing

    During Down Milling, The Gap Between The Lead Screw The Nut Changes, Which Will Cause Uneven Feeding Of The Worktable, Resulting In Impact Vibration, Affecting The Life Of The Machine Tool The Tool The Surface Roughness Of The Workpiece. When Using Reverse Milling, The Cutting Thickness Changes Small To Large, The Tool Load Also Changes Small To Large, The Tool Is More Stable During Processing. Note That This Is Only Used During Fine Processing. Down Milling Should Still Be Used During Rough Processing Because Down Milling Has High Productivity The Tool Life Can Be Guaranteed.

7. Reasonable Use Of Cutting Fluid

    Reasonable Use Of Cutting Fluids. Aqueous Solutions That Are Mainly Used For Cooling Have Little Effect On Cutting Forces. Cutting Oils That Are Mainly Used For Lubrication Can Significantly Reduce Cutting Forces. Due To Its Lubrication Effect, It Can Reduce The Friction Between The Tool Rake Face The Chips Between The Back Face The Transition Surface Of The Workpiece, Thereby Reducing The Radial Runout Of The Tool.

    Practice Has Proved That As Long As The Manufacturing Assembly Accuracy Of Each Part Of The Machine Tool Is Guaranteed Reasonable Processes Tooling Are Selected, The Impact Of The Radial Runout Of The Tool On The Machining Accuracy Of The Workpiece Can Be Minimized.
