The taper, or bevel, is cut by setting the cross-slide appropriately then using the compound slide feed handle to 

advance the cutting tool in the direction of the arrow as shown in Fig.9. 

 

 

Screw Cutting 

This operation requires a degree of skill and accuracy and should not be attempted unless you are completely 

familiar with all aspects of the lathe.  

Essentially, the carriage/saddle will move towards the headstock under power, the same as cutting with auto 

feed, except the rate of feed is greater, as determined by the gear configuration. The cutting tool, therefore, is 

moving ever closer to the rotating chuck. Great care and concentration must be exercised to ensure that the two 

do not meet when the machine is operating, as the possible damage caused could be disastrous. 

The lathe is supplied with a lead screw that will produce Imperial Threads in a range from 12 to 52 threads per 

inch, or metric threads in a range from 0.4-2.0mm pitch. It is important to remember that the type of thread you 

need to cut (i.e., UNF, BA, BSP, BSW etc.), will be totally dependent upon the cutting tool profile, as profiles 

differ from thread to thread. For detailed information regarding screw cutting techniques, cutting tools, etc., you 

should consult a suitable handbook or obtain advice and/or training from a qualified person. 

The general procedure for screw cutting is as follows: 
1.  Try to get as much distance from the chuck to the end of the proposed screw thread as possible, and if your 

design allows, cut a 'run-off' into the work piece which is of a smaller diameter than the root diameter of the 

proposed screw thread. 

2.  Install the appropriate gears for the thread required, and correctly mount the cutting tool. Set your required 

depth of cut and position the tool ready to begin cutting. 

NOTE

: Depth of cut is vitally important and may be calculated or obtained from an appropriate reference 

manual. 

3.  Take all necessary precautions previously stated and start the machine with the automatic feed lever in its' 

disengaged position (UP). 

4.  Engage the auto-feed lever sharply, turn the FORWARD/OFF/REVERSE (F/O/R) switch (B) to 'FORWARD'. 

As the tool approaches the end of the desired thread, turn the switch (B) to 'OFF’. Do not disengage the 

auto-feed lever.
