Slim shaft machining method for small precision parts machining centre

The Market Demand For Small Precision Parts Is Growing. In The Process Of Developing Product Applications, Various Manufacturing Industries Need To Order Only Relatively Simple Parts In Large Quantities, But Also Increasingly Complex Precision Parts Made Of Bar Materials . In This Highly Competitive Field, Machine Tool Technology Has Developed By Leaps Bounds, One Of The Current Focuses Is To Develop New Cutting Tools To Increase Machine Tool Utilization Component Production.

In The Manufacturing Industry, Small Precision Parts Machining  Turning Parts Is A Strong Growth Market. The Demand For These Parts In The Medical, Hydraulic, Connector, Automotive, Information Electronics Home Appliance Industries Is Rising Rapidly. In Addition, In The Aerospace Defense Industries, Equipment Control Systems Are Increasingly Equipped With Electronic Hydraulic Components, So Suppliers In These Industries Have Also Become Active Users Of Small Tools.

This Development Trend Shows That More More Small Precision Parts Are Being Processed In Smaller Smaller Batches. Huiwen Zhizao Is A Machining Plant With More Than Ten Years Of CNC Machining Experience , With Complete Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining. Huiwen Has Long Been Committed To The Processing Of High-Precision, High-Difficulty, Easy-To-Deform Metal Plastic Parts , The Small Medium-Batch Production Of Light Alloy Composite Materials (Such As Aluminum Alloy, Carbon Fiber, Etc.), The Procurement Customization Of Robot Parts . Partners With Precision Parts Processing Needs Are Welcome To Call For Quotations. Especially In The Medium Large-Scale Production Of Small Parts, The Competition Is Very Fierce. Many Parts Are Relatively Simple In Design Are Often Made Of Materials That Are Easy To Machine . But Market Demand Is Growing, New Applications Require More Complex Parts Require These Parts To Be Made Of Materials That Are More Difficult To Process. In This Cost-Sensitive Manufacturing Industry, It Is Key For Companies To Adopt Modern Methods Methods To Enhance Production Competitiveness. Let's Take A Look At How Huiwen Zhizao Engineers Process Slender Shafts?

Since The Rigidity Of The Slender Shaft Is Very Poor, It Is Very Easy To Deform During Processing, Which Has A Great Impact On The Processing Accuracy 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 Workpiece Is Subjected To Large Cutting Force. 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 That The Workpiece Will Be Separated The Top. The Use Of The Carra Method Can Avoid This Phenomenon.

During Finish Turning, The Use Of The Double Center Method (The Tailstock Should Use An Elastic Center In This Case) Is Beneficial To Improving 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 Tool For Turning Slender Shafts Generally Has A Large Rake Angle Main Deflection Angle To Make Cutting Easier Reduce Radial Vibration Bending Deformation. The Turning Tool For Roughing Has A Chip Breaker Groove On The Rake Face To Make Chip Breaking Easier. The Tool For Fine Turning Often Has A Certain Negative Edge Inclination Angle To Make The Chips Flow To The Surface To Be Processed.
