This will clean and smooth the previous cut. 6. When the cut is complete, press the red Off button. Machining Cones Manually This operation is similar to machining cylinders with the following differences. 1. To manually cut a cone, determine the taper requirement and turn the small cutter rest to the desired slope on the workpiece. Retighten the cutter rest. 2. Press the green On button to start the lathe. 3. Turn the Straight Lever (F) clockwise to make the cut. Automatically 1. To automatically cut a cone, determine the taper requirement and turn the small cutter rest to the desired slope on the workpiece. Retighten the cutter rest. 2. Horizontally move the tailstock from the spindle centerline to the required slope on the far right surface of the work piece. 3. Press the green On button to start the lathe. 4. Press down on the Straight Lever (G) to engage apron clasp nut over the Gear Shaft. The tool will automatically move from right to left while cutting the workpiece. 5. Repeat steps 2 through 4 until the desired cone size is cut. 6. When the cut is complete, press the red Off button. Machining Threads The Gear Box is composed of the change gears, shaft bolt, fixing shaft bolt, and square nut. The change gear box is fixed on the left support of the leadscrew (101). To cut threads, select the proper change gears for the desired thread type (see Thread Formula Table), and engage with approximately 0.1 mm tolerance. Tighten Screw (835). The Fixed Shaft Bolt (825) under the spindle is used for right hand cutting and threading. The set of Fixed Shaft Bolts in the accessory kit is used in combination with the original set of Shaft Bolts to reverse the rotation of the long leadscrew for left-handed threading and cutting. The change gear for metric or inch threading is selected according to the Thread to Gear formula and table. The feed amount depends on the material to be cut, the surface roughness, and finish requirements. If the two settings “0.1 and 0.2”, of the Gear table do not meet the requirement, you can add or change gears. The same is true if the number of teeth listed in the Gear table do not coincide with the calculated number of teeth. In this case, use gears with similar number of teeth. In doing so, however, the following relationship of the driving shaft must be met: Z3+Z4+>Z2+Z5. Otherwise, the addendum of circles A2 and Z5 will hit each other. The left formula below is an example of 0.3 mm spindle round. The right formula is an example for 8 threads per inch. The Thread to Gear settings table on the following page allows you to select the number of threads per inch or millimeter, and which gears need to be used. Rest Accessories The Follow Rest (not supplied) is mainly used for cutting long and thin shaft pieces to ensure no bending takes place during cutting. It also provides a better finish surface as a result of less vibration. The Steady Rest (not supplied) provides a similar function as with the Follow Rest. The difference being that the Steady Rest is fixed on the bed guides, and does not follow the movement of the cutting tool. Both rests can be purchased from Harbor Freight Tools. Maintenance General 1. Unplug power cord from receptacle when not in use. 2. Using compressed air, blow off all dirt and particles after using. 3. Keep all tools sharp. 4. Cover Lathe when not in use. 5. Periodically, check all bolts and nuts for tightness. Lubrication Lubricate the Lathe daily using an appropriate machine oil from a forced-feed oil can.
