Slim shaft machining method for small precision parts machining centres

Whenever A CNC Processing Plant Receives A New Key Task, It Will Always Carefully Analyze The Difficulties, Sort Out The Process Flow, Reconstruct It As Needed To Improve The Product Qualification Rate. There Is A Key Component That Consists Of Multiple Parts. There Must Be A Reasonable Gap Between The Parts To Ensure Flexible Unobstructed Movement, But It Cannot Be Loose. The Processing Accuracy Of Its Mating Surface Is Only A Fraction Of A Hair, Which Must Be Guaranteed By Manual Scraping. After The Precision Parts Processing Center Took Over, It Conducted A Careful Detailed Study On The Processing Technology Measurement Methods Of The Parts, Improved The Processing Tools, Measurement Methods, The Control Of The Matching Clearance After Surface Treatment. For Example, The Slender Shaft Processing Method Has A Very Poor Rigidity Of The Slender Shaft, Which Is Very Easy To Deform During Processing, Which Has A Great Impact On The Processing Accuracy Processing Quality. For This Reason, The Following Measures Are Often Used In Production To Solve It.

(I) Improve The Clamping Method Of The Workpiece

During Rough Machining, Due To The Large Cutting Allowance, The Cutting Force On The Workpiece Is Also Large. The Clamping Method Is Generally Used, The Tailstock Top Uses An Elastic Top, Which Can Allow The Workpiece To Stretch Freely In The Axial Direction. However, Due To The Limitation Of The Top Elasticity, The Axial Elongation Is Also Limited, So The Clamping Force Is Very Large. When Cutting At High Speed Large Volume, There Is A Danger Of The Workpiece Detaching The Top. The Kara Method Can Avoid This Phenomenon. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has A Full Range Of Equipment, CNC Turning/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

During Fine Turning, The Precision Parts Machining Center Uses The Double Center Method (The Tailstock Should Use An Elastic Center Tip In This Case) To Help Improve Accuracy, The Key Being To Improve The Accuracy Of The Center Hole.

(Ii) Use A Tool Holder

The Tool Rest Is An Extremely Important Accessory For Turning Slender Shafts. The Use Of The Tool Rest Can Offset The Influence Of The Radial Cutting Force During Machining, Thereby Reducing Cutting Vibration Workpiece Deformation, But It Must Be Carefully Adjusted To Keep The Center Of The Tool Rest Consistent With The Center Of The Machine Tool Top.

(III) Using Reverse Feed

When Turning A Slender Shaft, The Turning Tool Is Often Fed Toward The Tailstock (A Kara Tool Should Be Installed At This Time). In This Way, The Feed Force Applied By The Tool On The Workpiece Is Directed Toward The Tailstock, Which Tends To Cause The Workpiece To Stretch Axially. The Kara Tool Greatly Reduces The Bending Deformation Caused By The Elongation Of The Workpiece.

(IV) Using Turning Tools For Turning Slender Shafts

The Turning Tools For Turning Slender Shafts Generally Have Larger Rake Angles Main Deflection Angles To Make Cutting Easier Reduce Radial Vibration Bending Deformation. The Turning Tools Used For Roughing Have Chip Breaker Grooves On The Front Cutting Edge To Make Chip Breaking Easier. The Tools Used For Finishing Often Have A Certain Negative Edge Inclination Angle To Make The Chips Flow To The Surface To Be Processed. Shenzhen Huiwen Intelligent Manufacturing Technology Co., Ltd.
