CNC precision parts machining methods characteristics

CNC Machining Is An Advanced Machining Technology In Today's Machinery Manufacturing Industry. It Inputs The CNC Program Of The Machined Parts Into The CNC Machine Tool, The Machine Tool Automatically Processes The Workpiece After Receiving The CNC Program. CNC Machining Technology Can Effectively Handle The Complex, Small Medium-Sized Batches Of Hardware Parts Meet The Needs Of Modern Production.

CNC Machining Technology Involves Tool Selection, Cutting Parameters Tool Paths. CNC Machining Technology Is The Core Content Of CNC Programming. Only By Selecting CNC Programs With Less Processing Time The Smallest Tool Path Can High-Efficiency High-Quality Products Be Obtained. CNC Machining Technology Can Be Divided Into Rough Machining, Corner Cleaning Fine Machining.

When Roughing, A Larger Tool Should Be Used To Quickly Remove A Lot Of Workpiece Excess At The Maximum Power Of The Machine Tool To Rough The Precision Parts . The Principle Of Tool Selection Is Mainly Based On Whether The Chamfered Arc Surface Of The Product Is Too Small. After Selecting The Tool, The Tool Length Is Determined. In Principle, The Tool Length Should Be Greater Than The Processing Depth.

The Tools We Use Are All Angled, Generally, The Stepped Shaft Needs To Be Cleaned. We Mill A Tool Retraction Groove The Corner Needs To Be Cleaned. The Advantages Of Doing So Are: First, It Is Convenient For The Grinder To Retract The Grinding Wheel As Soon As Possible Without Grinding The End Face Affecting The Length; Second, The End Face Is Fully Contacted During Assembly, The End Face Runout Will Be Smaller.

The Purpose Of Finishing With A Polishing Knife Is To Meet The Surface Finish Of Precision Parts Achieve High-Precision Results. Therefore, The Polishing Knife Finishing Process Should Be Done At The Fastest Possible Speed With A Tool Of Appropriate Size For Feed. The Faster Larger The Feed, The Smoother The Machined Surface.
