Technical Information:

• NPT thread for steam, natural gas and water pipes.
• Turning threads are common operations on CNC machines. The use of indexable tools to cut threads enables safe and high productivity of the process.
• The feed of the machine is the most important factor in turning the thread: it must be equal to the pitch, which is the distance between a point on the thread and the corresponding point of the adjacent thread. The fit between the pitch and the feed per revolution is accomplished by controlling subroutines in the CNC machine.
• Thread turning should initially consider three aspects to determine the best method and tool selection for threading:
  • Main parameters of the thread:
    • External or internal thread
    • Thread type
    • Pitch
    • Right or left hand thread
    • Tolerance
  • Workpiece material properties, shape and quantity
    • Whether the workpiece is safely clamped
    • Whether there is any problem with chip removal
    • Workpiece batch
  • Machine parameter
    • Stability, power and torque requirements, especially for larger diameter threading
    • Workpiece clamping condition
    • Threading cycle should be easy to program
    • Cutting fluid and coolant
