Other Specification : For Hard Rock,
abrasive Wear Is Relatively Low, Such As Granite (impact Or Rotary Impact Drills), Alloy Failure Is Mainly Caused By The Shock And Impact Fatigue. The Compressive Strength And Flexural Strength Of The Alloy Alloy Directly Impact Performance-related Fatigue; Addition, Phase And The Alloy Purity Of WC Grain Size And Co Mean Free Path Related. Furthermore, The Impact Of Fatigue Properties Of The Alloy Is Directly Related To The Impact Energy.For Hard Rock,

For Hard Rock, Such As Quartzite (Impact Drills), Dominated By Abrasive Wear. Abrasive Wear Coarse Grain Drilling Carbide New Progress.
On The Basis Of Analyzing The Carbide Drilling Failure Mechanism Indicating The
ultra-coarse Grain Carbide Because Of Having Good Thermal Conductivity, Impact Toughness And Resistance To Thermal Fatigue, And Have Been Widely Used In The Drilling Tool, And The The Coarse Grain Drilling Carbide Production Of New Technology.
Carrying High-impact And High Load, Or
mechanical Vibrations Under Hard Cutting Conditions Are Required Carbide Has A Better Strength And Fracture Resistance. In Addition, We Also Know That Compared With The Fine Grain Cemented Carbide Coarse WC Grain Size Is
