Why must "tool material × workpiece material" be evaluated together?
Why must "tool material × workpiece material" be evaluated together?
Why must "Tool Material × Workpiece Material" be evaluated together?
The lifespan and machining quality of threading tools should not be judged solely by the hardness of the tool material.
Practical applications must consider the following simultaneously:
• Workpiece material
• Final workpiece hardness
• Material machinability
• Workpiece material adhesion
• Workpiece material work hardening characteristics
• Chip morphology
• Thread depth
• Blind holes or through holes
• Chip breaking capability at the thread tip
• Threading tool chip removal capability
• Threading tool structure
• Threading tool material
• Tool-workpiece adhesion
• Spindle runout
• Tool holder runout
• Cooling and lubrication conditions
• Machining method
• Production volume
• Tool life requirements
Therefore, UGMIC's precise Thread Material × Thread Problem framework is not a simple table of "one material, one tool," but rather uses workpiece material characteristics and thread machining problems as the entry point for tool selection and improvement.
