What happened to the unstable machining accuracy of 5-axis cnc machining factory?

CNC Processing Factories Use Precision CNC Machine Tools ( Machining Center , EDM, WEDM, Etc.) For High- Precision Processing. Do You Have This Experience: Every Morning When You Start The Machine For Processing, The Processing Accuracy Of The First Piece Is Often Good Enough ; The First Batch Of Parts Processed After A Long Vacation Often Have Very Unstable Accuracy, The Probability Of Failure Is Extremely High During High-Precision Processing, Especially The Position Accuracy.

Five-Axis CNC Processing Factories Without Experience In Precision Processing Often Attribute The Cause Of This Unstable Precision To Equipment Quality Problems. Factories With Experience In Precision Processing Pay Great Attention To The Thermal Balance Of Ambient Temperature Machine Tools. They Know Very Well That Even High-Precision Machine Tools Can Only Obtain Stable Processing Accuracy In A Stable Temperature Environment Thermal Balance State. In The Case Of A Five-Axis CNC Processing Factory That Will Start High-Precision Processing Production After Starting Up, Preheating The Machine Tool Is The Most Basic Common Sense Of Precision Processing.

01 Why Does A CNC Machining Plant Need To Preheat Machine Tools?

The Thermal Characteristics Of CNC Machine Tools Have An Important Influence On Machining Accuracy, Accounting For More Than Half Of The Machining Accuracy. The Spindle Of The Five-Axis CNC Machining Factory Machine Tool, The Guide Rails, Lead Screws Other Components Used In The XYZ Motion Axis Will Heat Up Deform Due To Load Friction During Movement, But The Final Factor Affecting The Machining Accuracy In The Thermal Deformation Error Chain Is The Displacement Of The Spindle XYZ Motion Axis Components Relative To The Workbench. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience , With A Full Range Of Equipment, CNC Turning/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

There Is A Big Difference In The Machining Accuracy Of The Machine Tool When It Is Stopped For A Long Time In The Thermal Equilibrium State. The Reason Is That After Running For A Period Of Time, The Temperature Of The Spindle Each Moving Axis Of The CNC Machine Tool Is Relatively Maintained At A Certain Fixed Level, With The Change Of Machining Time, The Thermal Accuracy Of The CNC Machine Tool Tends To Be Stable, Which Shows That It Is Very Necessary To Preheat The Spindle Moving Parts Before Machining.

However, The Preparation Link Of "Warm-Up Exercise" Of Machine Tools In Five-Axis CNC Machining Factories Is Ignored Unknown By Many Factories.

02How Does A CNC Processing Factory Preheat Machine Tools?

If The Machine Tool Has Been Idle For More Than Several Days, It Is Recommended To Preheat It For More Than 30 Minutes Before High-Precision Machining; If It Has Been Idle For Only A Few Hours, It Is Recommended To Preheat It For 5-10 Minutes Before High-Precision Machining.

The Preheating Process Is To Let The Machine Tool Participate In The Repeated Movement Of The Machining Axis. It Is Best To Perform Multi-Axis Linkage, Such As Moving The XYZ Axis The Lower Left Corner Of The Coordinate System To The Upper Right Corner, Repeatedly Moving Diagonally.

During Execution, A Macro Program Can Be Written On The Machine Tool To Allow The Machine Tool To Repeatedly Perform The Preheating Action.

After The Machine Tool Is Fully Preheated, The Energetic Machine Tool Can Be Put Into High-Precision Processing Production, You Will Obtain Stable Consistent Processing Accuracy.
