The Greater The Precision Deviation Of A Machining Manufacturer, The Greater The Deviation!

Machining Manufacturers Have Always Emphasized That The Products They Produce Must Meet The Level Of Precision, Which Means Thatthe Main Parameters Of The Actual Geometric Figures Of Steel Parts After Machining Are Consistent With The Idealized Values Required By The Part Drawings. The Inability To Achieve A Consistent Level In The Middle Is Called Production Processing Deviation; Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience, With Complete Equipment, CNC Turning/Milling/Grinding/Drilling/Processing.

    The Precision Of Products Produced By Machining Manufacturers Mainly Includes Three Aspects. On The One Hand, It Is The Dimensional Precision, Which Limits The Dimensional Deviation Between The Standard The Processing Surface Layer Within The Required Range. In Addition, The Geometric Shape Precision Limits The Macro-Geometric Shape Deviation Of The Processing Surface, Such As Roundness, Taper, Cylindricity, Parallelism, Concentricity, Straightness, Etc.

    Another Aspect Is The Relative Position Precision, Which Limits The Relative Position Deviation Between The Two Standard Machining Surfaces Produced By The Machining Manufacturer , Such As Coaxiality, Flatness Parallelism. The Machining Accuracy Is The Reasonable Level Between The Actual Size, Style, Component Concentrated Geometric Parameters Of The Surface Of The Parts After Machining The Ideal Geometric Parameters Specified In The Engineering Drawings;

    The Main Parameters Of Idealized Geometry Refer To The Average Dimensions For Specifications, Circles, Planes, Cylinders, Spheres Parallel Lines For Surface Geometry, Parallel Planes, Coaxial Outputs, Verticality, Symmetry, Etc. For The Mutual Parts In The Middle Of The Surface.

    The Difference Between The Actual Geometric Parameters The Ideal Geometric Parameters Of The Parts Produced By The Machining Factory Is Called The Processing Deviation. The Processing Accuracy Processing Deviation Are Both Professional Terms For Evaluating The Geometric Parameters Of The Processing Surface. The Processing Accuracy Is Measured By The Tolerance Grade. The Smaller The Grade Value, The Higher The Accuracy. The Processing Deviation Is Expressed By The Standard Value. The Larger The Standard Value, The Greater The Deviation.

    The Following Is A Brief Introduction By Huiwen On The Methods To Improve Workpiece Machining Accuracy:

1. Adjust The Process System

1) Trial Cutting Method: Trial Cutting - Measuring The Size - Adjusting The Cutting Depth Of The Tool - Cutting - Trial Cutting Again, Repeating This Process Until The Required Size Is Reached. This Method Has Low Production Efficiency Is Mainly Used For Single-Piece Small Batch Production.

2) The Adjustment Method Obtains The Required Size By Pre-Adjusting The Relative Positions Of The Machine Tool, Fixture, Workpiece Tool. This Method Has High Productivity Is Mainly Used For Large-Scale Mass Production.

2. Reduce Machine Tool Errors

1) The Rotation Accuracy Of The Bearing Should Be Improved:

① High-Precision Rolling Bearings;

②Use High-Precision Multi-Oil Wedge Dynamic Pressure Bearing;

③Use High-Precision Hydrostatic Bearings

2) Improve The Accuracy Of Accessories With Bearings:

① Improve The Machining Accuracy Of The Box Support Holes Spindle Journals;

② Improve The Machining Accuracy Of The Surface Matching The Bearing;

③Measure Adjust The Radial Runout Range Of Corresponding Parts To Compensate Offset The Errors.

3) Properly Preload The Rolling Bearing:

①Can Eliminate Gaps;

②Increase Bearing Stiffness;

③Evenate Rolling Element Errors.

4) Make Sure That The Spindle Rotation Accuracy Is Reflected On The Workpiece
