  Processing Composite Materials Requires Precise Processing According To The Type Of Composite Materials. Huiwen Intelligent Manufacturing Takes CNC Machining Technology As The Core To Provide You With High-Quality Processing Manufacturing Services. Here Is A Brief Introduction To Some Issues That The Machining Center Should Pay Attention To When    Processing Composite Materials :

  1. Types Of Composite Materials For Machining Centers   

  Composite Materials Are Divided Into Metal-Metal Composite Materials, Non-Metal-Metal Composite Materials, Non-Metal-Non-Metal Composite Materials According To Their Composition. According To Their Structural Characteristics, They Are Further Divided Into: 


  1. Fiber Composite Materials. Various Fiber Reinforcements Are Placed In The Matrix Material For Compounding. Such As Fiber Reinforced Plastics, Fiber Reinforced Metals, Etc.    

  2. Sandwich Composite Materials. It Is Composed Of Surface Materials Core Materials With Different Properties. Usually The Surface Material Is High-Strength Thin; The Core Material Is Light Low-Strength, But Has A Certain Rigidity Thickness. It Is Divided Into Solid Sandwich Honeycomb Sandwich. Huiwen Intelligent Manufacturing Technology Has Long Been Committed To The Processing Of High-Precision, High-Difficulty, Easy-To-Deform Metal Plastic Parts , Small Medium-Volume Production Manufacturing Of Light Alloy Composite Materials (Such As Aluminum Alloy, Carbon Fiber, Etc.),  Robot Parts Procurement Customization Services.

  3. Fine-Grained Composite Materials: Distribute Hard Fine Particles Evenly In The Matrix, Such As Dispersion-Strengthened Alloys, Metal Ceramics, Etc.   

  4. Hybrid Composite Materials. They Are Composed Of Two More Reinforcing Phase Materials Mixed In One Matrix Phase Material. Compared With Ordinary Single-Reinforcement Phase Composite Materials, Their Impact Strength, Fatigue Strength Fracture Toughness Are Significantly Improved, They Have Special Thermal Expansion Properties. They Are Divided Into Intra-Layer Hybrid, Inter-Layer Hybrid, Sandwich Hybrid, Intra-Layer/Inter-Layer Hybrid Super-Hybrid Composite Materials. 

  2. Some Issues That Should Be Paid Attention To When Machining Composite Materials In Machining Centers 

  1. The Interlayer Strength Of Carbon Fiber Composite Materials Is Low, It Is Easy To Produce Delamination Under The Action Of Cutting Force. Therefore, The Axial Force Should Be Reduced When Drilling Cutting. Drilling Requires High Speed Small Feed. The Speed Of The Machining Center Is Generally 3000~6000r/Min, The Feed Rate Reaches 0.01~0.04mm/R. It Is Better To Use A Three-Pointed Two-Edge Two-Pointed Two-Edge Drill. The Sharp Tip Can First Cut The Carbon Fiber Layer, The Two Edges Have A Repairing Effect On The Hole Wall. The Diamond-Studded Drill Is Sharp Wear-Resistant. Drilling Of Composite Materials Titanium Alloy Interlayers Is A Difficult Problem. Generally, A Solid Carbide Drill Is Used. Drilling Is Carried Out According To The Cutting Parameters Of Drilling Titanium Alloys. Drill The Titanium Alloy Side First Until It Is Drilled Through. Lubricant Is Added During Drilling To Relieve Burns Of Composite Materials. Boeing Has Specially Developed A PCD Combination Drill For Drilling Interlayers.    

  2. The Three New Types Of Special Milling Cutters For Processing Solid Carbide Composite Materials Have Better Cutting Effects. They All Have Some Common Characteristics: High Rigidity, Small Helix Angle, Even 0°, Specially Designed Herringbone Blades, Which Can Effectively Reduce The Axial Cutting Force Of The Machining Center Reduce Delamination. Their Processing Efficiency Effects Are Very Good.    

  3. Composite Material Chips Are Powdery Harmful To Human Health. A High-Power Vacuum Cleaner Should Be Used To Remove Dust. Water Cooling Can Also Effectively Reduce Dust Pollution.    

  4. Carbon Fiber Composite Material Processing Components Are Generally Large In Size, Complex In Shape Structure, With High Hardness Strength, Are Difficult To Process Materials. The Cutting Force Is Large During The Cutting Process, The Cutting Heat Is Easy To Be Transmitted. In Severe Cases, The Resin Will Be Burned Softened, The Tool Will Be Severely Worn. Therefore, The Tool Is The Key To Carbon Fiber Processing . Its Cutting Mechanism Is Closer To Grinding Rather Than Milling. Therefore, The Cutting Line Speed Of The Machining Center Is Usually Greater Than 500m/Min, A High-Speed Low-Feed Strategy Is Adopted. The Trimming Tools Generally Use Solid Carbide Knurling Milling Cutters, Electroplated Diamond Grain Grinding Wheels, Diamond-Set Milling Cutters, Copper-Based Diamond Grain Saw Blades.
