Precautions to be taken when forming machining high-precision workpieces

1) When Performing High-Precision Workpiece Forming, Use A Micrometer To Detect The Tool On The Spindle To Control Its Static Runout Within 3µm. If Necessary, Re-Clamp Replace The Tool Holder System;

2) Whether It Is A High-Precision Part Processed For The First Time A High- Precision Part That Is Repeatedly Processed Periodically , Before Processing, It Is Necessary To Check Verify Each Tool Each Program Section According To The Drawing Process, Program Tool Adjustment Card, Especially For The Tool Length Compensation Radius Compensation In The Program, Do Trial Cutting If Necessary; Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience , With Complete Equipment, CNC Turning/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotation.

3) When Performing Single-Stage Trial Cutting For Precision Machining , The Rapid Rate Switch Must Be Set To A Lower Level;

4) When Using Each Knife For The First Time, You Must First Verify Whether Its Actual Length Matches The Given Compensation Value;

5) During Program Operation, Pay Special Attention To Several Displays On The CNC System;

6) Coordinate Display: You Can Understand The Position Of The Current Tool Motion Point In The Machine Tool Coordinate System The Workpiece Coordinate System, Understand The Motion Amount Of This Program Segment, How Much Remaining Motion There Is, Etc.;

7) Register Buffer Register Display: You Can See The Status Instructions Of The Program Segment Being Executed The Content Of The Next Program Segment.

8) Main Program Subprogram Display: High-Precision Workpieces Can Understand The Specific Content Of The Program Segment Being Executed.

9) Dialogue Display Screen (Custom): You Can Understand The Current Spindle Speed, Current Cutting Feed Speed, Cutting Feed Per Spindle Revolution, Current Cutting Load Of The Spindle Cutting Feed Per Spindle Revolution Of Each Stroke Shaft Load To Calculate The Corresponding Cutting Amount Per Tool Edge;

10) When Trial Cutting High-Precision Parts, When The Tool Moves To 30~50mm The Workpiece Surface, It Is Necessary To Verify Whether The Remaining Coordinate Values Of The Coordinate Axis The X Y Axis Coordinate Values Are Consistent With The Drawing At A Low Feed Speed;

11) For Some Tools That Require Trial Cutting, Use The "Progressive" Method. For Example, When Boring Holes In Precision Parts , You Can First Try Boring A Small Length, Then Bore The Entire Length After Passing The Test. The Tool Data Using The Tool Radius Compensation Function Can Be Modified Large To Small While Trial Cutting;

12) During Trial Cutting Precision Machining, After Replacing The Tool Auxiliary Tools, Be Sure To Re-Measure The Tool Length Modify The Tool Compensation Value Tool Compensation Number;

13) When Searching For A Program, Pay Attention To Whether The Cursor Position Is Reasonable Accurate, Observe Whether The Coordinates Of The Tool Machine Tool Movement Direction Are Correct;

14) After The High-Precision Workpiece Program Is Modified, The Modified Part Must Be Carefully Calculated Checked;

15) When Operating Manual Feeding Manual Continuous Feeding, You Must Check Whether The Positions Of Various Switches Are Correct, Find Out The Positive Negative Directions, Identify The Buttons The Set Feed Speed Pulse Ratio, Then Operate.
