Threading Inserts Wear Problems and Solutions

Turn Thread

Mill Thread

Type of Wear

- ×
  
  Plastic Deformation
  Plastic Deformation
  
  Cause
  - Excessive heat in cutting zone
  - Wrong grade
  - Inadequate coolant supply

  - Check center height
- ×
  
  Poor Chip Control
  Poor Chip Control
  
  Cause
  - Excessive heat in cutting zone
  - Wrong grade
  - Inadequate coolant supply
  - Wrong turned dia. prior to threading
  - Incorrect method of infeed
  Remedy
  - Reduce RPM /change depth of cut /check turned dia.
  - Use coated grade /check turned dia./use M/B type inserts
  - Apply coolant
  - Check turned dia.
  - Modified flank infeed 3-5°
- ×
  
  Thread Profile is Too Shallow
  Thread Profile is Too Shallow
  
  Cause
  - Incorrect center height
  - Worn insert
  - Insert isn’t machining the tread crest
  - Excessive wear
  Remedy
  - Check center height
  - Change to new cutting edge sooner
  - Check the workpiece dia.
  - Increase radial infeed
- ×
  
  Broken Nose During First Pass
  Broken Nose During First Pass
  
  Cause
  - Cutting edge too cold
  - Depth of cut too large
  - Wrong grade
  - Wrong turned dia. prior to threading
  - Incorrect center height
  - Infeed depth too shallow
  - Wrong inclination anvil
  - Tool overhang tool long
  Remedy

  - Adjust center height
  - Change the program

Flank Wear

Cause	High cutting speed
Remedy	Reduce cutting speed

Cause	Chip too thin
Remedy	Increase feed rate and reduce radial passes

Cause	Insufficient coolant
Remedy	Check coolant pressure / flow direction

Fracture/Chipping

Cause	Vibration
Remedy	Check stability

Cause	High load on cutting edge
Remedy	Reduce feed rate Add radial passes

Build-up Edge

Build up Edge

Cause	Cutting speed too low
Remedy	Increase cutting speed

Cause	Insufficient coolant
Remedy	Check coolant pressure / flow direction

Thread Surface-Chatter Marks/Vibrations

Cause	Feed rate is too high
Remedy	Reduce feed rate

Cause	Large profile
Remedy	Add passes

Cause	Thread length too long
Remedy	Add radial passes Reduce overhang

Thread Accuracy (GO/NOGO Gauge)

Cause	Tool deflection
Remedy	Reduce feed rate Add radial passes Use ZERO compensation

Cause	CNC program error
Remedy	Check CNC program

Insert/Tool Breakage

Cause	High load on the cutting edge
Remedy	Add radial passes

Cause	Unproper cutting conditions
Remedy	Adjust cutting conditions

Cause	Chip evacuation
Remedy	Add sufficient coolant

Cause	CNC program error
Remedy	Check CNC program

Tapered Thread

Cause	Tool cutting load
Remedy	Add radial passes and/or reduce cutting conditions

Cause	Tool overhang
Remedy	Clamp tool to the minimum overhang length

Short Tool Life

Cause	Unsuitable cutting conditions
Remedy	Adjust feed/speed
