• For longer workpieces, use the tailstock for additional support.

4.3 Tool Holder and Tooling

• Mount turning tools securely in the tool post.
• Ensure the cutting edge of the tool is aligned with the center height of the workpiece.
• The maximum tool holder capacity is 8 mm.

4.4 Speed and Feed Control

The spindle speed is continuously variable from 50 to 2500 min^-1 via the control knob. Adjust the speed according to the material being machined and the cutting tool used.

Figure 4: Close-up of the cross slide and feed mechanism. This image highlights the handwheel for cross-feed, the graduated dial for precise adjustments, and the lever for engaging the automatic longitudinal feed. The "16T" label likely refers to a gear setting for specific operations.

• Automatic Longitudinal Feed: Engage the lead screw for automatic longitudinal turning.
• ത്രെഡ് കട്ടിംഗ്: The lathe supports metric threads from 0.5 to 2.5 mm/r. Use the standard included metal change gears to set the desired thread pitch. Refer to the machine's gear chart for specific configurations.
• Cross Slide and Compound Slide: Use the handwheels for manual control of the cross-feed (70 mm travel) and compound slide (70 mm travel). The tailstock can be offset for taper turning.
