4.7.1 General Thread Cutting Principles
Threads are cut by synchronizing the movement of the carriage with the rotation of the spindle using
the leadscrew.
The carriage advances in exact proportion to the spindle's rotation, allowing the cutting tool to trace a
helical path along the workpiece.
During threading operations, manual feed and automatic feed (via feed rod) are disabled; only
leadscrew-driven movement is used.
4.7.2 Setup for Thread Cutting
Select the Desired Thread Type:
o Imperial threads (4–56 TPI) or Metric threads (0.25–7 mm).
Adjust the Gearbox Levers:
o Refer to the Thread Chart on the machine to set the correct combinations of levers (A, B, C, D)
for the selected thread pitch.
Engage the Leadscrew:
o Shift the transmission lever to select leadscrew drive instead of feed rod.
4.7.3 Preparing the Machine
Mount the workpiece securely in the chuck or between centers.
Install a sharp threading tool in the toolpost and align it square to the workpiece axis using a thread
gauge or machinist's square.
Set the compound rest at a 29° angle (for imperial 60° threads) to facilitate proper cutting and chip flow.
Adjust spindle speed:
o Use lower speeds (typically 70–200 RPM) to allow better control during threading.
4.7.4 Threading Procedure
Start the spindle.
Set the carriage close to the starting point of the thread.
Observe the Thread Dial Indicator for imperial threads:
o Engage the Half-Nut Lever at appropriate marks (typically numbered or evenly spaced) when
the dial aligns.
For metric threads:
o Keep the half-nuts engaged throughout the entire threading operation. Do not disengage
between passes.
The carriage will now move in synchronization with spindle rotation, cutting the thread.
After completing a pass:
o Disengage the spindle, back the tool out slightly using the cross-slide handwheel.
o Return the carriage to the starting point without disengaging half-nuts (for metric threads) or by
retracting for imperial threads.
o Adjust the compound rest inward slightly to increase cutting depth for the next pass.
Repeat the process until the desired thread depth is achieved.
4.7.5 Important Notes
Use cutting fluid as needed to improve finish and tool life, especially on difficult materials like stainless
steel.
Keep hands clear of moving parts at all times.
Always verify thread pitch and thread form after cutting by using thread gauges or fitting the mating
part.
Never change spindle speed or engage/disengage half-nuts while the spindle is rotating.
4.8 Tailstock Operation
The tailstock is an essential component of the lathe, designed to support long workpieces, hold tooling for
