DRILLING OF GREY CAST IRON WITH SOLID CARBIDE DRILLS
|
| |
|
Summary :
|
|
THIS WORK HAS THE PURPOSE OF EVALUATING THE BEHAVIOR OF FIVE DIFFERENT TYPES OF SOLID CARBIDE DRILLS, PRODUCED BY FOUR DIFFERENT TOOLS MANUFACTURES WHEN MACHINING GRAY CAST IRON. ALTHOUGH IT IS CONSIDERED AN EASE-TO-MACHINE MATERIAL, ITS USE IS JUSTIFIED BY ITS LARGE APPLICATION IN THE INDUSTRY, MAINLY IN THE AUTOMOTIVE. THE DRILLS PRESENT DIFFERENCES IN GEOMETRY AND IN THE PRESENCE OF COATINGS. THE PERFORMANCE OF THE TOOLS IS EVALUATED BASED ON TOOL LIFE AND DIMENSIONAL QUALITY OF THE HOLES. THE PRESENCE OF THE TIALN COATING, IMPROVED THE DRILL LIFE AND THEREFORE RESPONSIBLE FOR THE BEST RESULTS.
KEY WORDS: DRILLING, CAST IRON, SOLID CARBIDE DRILLS, COATED SOLID CARBIDE DRILLS.
