Points For Attention In Processing Of Precision Machinery Parts

There Are Many Precise Procedures In The Processing Of Precision Mechanical Parts; Therefore, There Are Many Issues In This Process That Require Our Attention, But There Are Three Main Points That Require Our Operators' Attention. The Following Editor Will Tell You:

Points For Attention In Processing Of Precision Machinery Parts

1. In Order To Ensure The Machining Accuracy, Rough Machining And Finishing Are Best Carried Out Separately:

During Rough Machining, The Amount Of Cutting Is Large, The Cutting Force And Clamping Force On The Workpiece Are Large, The Heat Generation Is Large, And The Machined Surface Has Obvious Work Hardening Phenomenon, So There Is A Large Internal Stress Inside The Workpiece. If Rough Machining Is Continued, The Accuracy Of The Finished Part Will Be Quickly Lost Due To The Redistribution Of Stress. For Some Parts With High Machining Accuracy. After Rough Machining And Before Finishing, Low Temperature Annealing Or Aging Treatment Should Be Arranged To Eliminate Internal Stress.

2. Reasonable Choice Of Equipment:

Rough Machining Is Mainly To Cut Off Most Of The Machining Allowance, Which Does Not Require High Machining Accuracy. Therefore, Rough Machining Should Be Performed On A High-Power, Low-Precision Machine Tool, While The Finishing Process Requires A High-Precision Machine Tool. Rough Machining And Finishing Are Carried Out On Different Machine Tools, Which Not Only Can Give Full Play To The Capabilities Of The Equipment, But Also Prolong The Service Life Of Precision Machine Tools.

3. In The Processing Route Of Precision Mechanical Parts, The Heat Treatment Process Is Often Arranged:

The Location Of The Heat Treatment Process Is Arranged As Follows: In Order To Improve The Workability Of The Metal, Such As Annealing, Normalizing, Quenching And Tempering. Usually Arranged Before Processing. In Order To Eliminate Internal Stress, Such As Aging Treatment And Quenching And Tempering Treatment, It Is Generally Arranged After Rough Machining And Before Finishing. In Order To Improve The Mechanical Properties Of Parts, Such As Carburizing, Quenching And Tempering, It Is Generally Arranged After Processing. If The Deformation Is Large After Heat Treatment, The Final Processing Procedure Must Be Arranged.

2. Safety Precautions In The Processing Of Precision Mechanical Parts:

1. Simple Operation, Reduce Walking Back And Forth, Avoid Unnecessary Bending And Toe Movements.

2. The Positioning Is Accurate And Reliable To Prevent Misoperation Caused By Slight Vibration.

3. The Direction Of Movement Of Operating Parts And Operated Parts Of Machine Tools And Equipment Should Comply With Regulations And Be Marked With Simple Symbols.

4. The Structure And Arrangement Of The Handle, Handwheel, And Buttons Should Meet The Requirements. The Start Button Should Be Installed In The Shell Or Equipped With A Guard Ring To Prevent Accidental Touch. The Handwheel And Handle Installed On The Shaft Will Hurt People As The Shaft Rotates During The Automatic Feeding Process, So An Automatic Release Device Should Be Installed.
