OPERATION

SET-UP FOR SIMPLE TURNING
Before beginning any project, it is critical that the Lathe unit be properly set up for the type of work to be performed.
The following section describes how to set up the Lathe in order perform a simple turning operation.
ALWAYS plan for the work to be done. Detailed drawings or notes along with any required measuring equipment such as micrometers, verniers, calipers etc.
should be on hand.
• Select a cutting tool that will produce the desired cut and mount it in the Tool
Rest, with as little overhang as possible, securing it with at least two of the
socket Head screws as shown in (FIG 12). Ideally, the overhang should be 0.38"
[10mm] but not more than 0.59" [15mm] for a straight tool.
• It is IMPORTANT that the tip of the cutting tool is on the center line of the work,
or very slightly below it. It MUST NEVER be above the center line.
• At the correct cutting height, the tip of the tool should be in exact alignment with
the point of the Tail Stock center. If not, it may be necessary to make adjust-
ments using shims, grinding the cutting tool tip, or selecting another tool.
• When adjusted, mount the workpiece, either in the chuck or on a faceplate, and if
necessary, use the Tailstock Center for additional support (If the work cannot be
adequately secured by the chuck, if it is an excessively long piece, or of small diam-
eter). Additionally, optionally available 'Steadies' may be used (not included).
• If the Tailstock is not to be used, it may be removed completely by loosening the securing nut at the base and sliding it free of the bed.
• Mark the surface of the work at the point where the cut is to end using a scriber or similar tool, and move the Saddle so that the cutting tool is directly
opposite the mark, then wind in the Cross-Slide so that the tool touches the surface of the work.
• While making these adjustments, rotate the Chuck by hand to prevent anything from contacting it when turning takes place and that there is adequate
clearance between the Saddle, Cross-Slide, Tool Post or cutting tool and the Chuck.
• It may be necessary to adjust the position of the Compound Slide or reposition the work in the Chuck to guarantee that there is adequate clearance.
• When ready for cutting, retract the Cutting Tool and wind the Saddle away from the Headstock.
"ZEROING" PROCEDURE
• Next, wind the Cutting Tool up to the workpiece somewhere along the length to
be cut while slowly rotating the Chuck by hand. Continue to advance the Cutting
Tool slowly until it just touches the workpiece surface. Record this position by
"zeroing" the scale on the Cross-Slide Scale by turning the moveable scale until
the "zero" marks are in alignment (FIG 13).
• Once "zeroed", retract the Cross-Slide one complete turn then move the Saddle
until the Tool is a short distance from the right edge of the workpiece.
• Slowly wind the Cross-Slide back in one full turn until the Zero marks are once
again aligned.
If the number mark moves past the previously "zeroed" alignment, back off again at least 1/2 turn then slowly rotate the
Cross-Slide to bring the scale back into Zero alignment.
It should be noted that whenever the Scale is used to advance the Cross-Slide or Compound Slide, ALWAYS use this procedure
to compensate for any backlash and clearances in the gearing, slides etc.
• Continue to turn the Handle an amount equal to the desired finished depth of cut.
NOTE: It is recommended for rough cutting not to exceed 0.010" [0.25mm] as a depth of cut.
The Set-Up is now complete to begin the cutting operation but as a checklist before starting, check the position of:
- The Auto Feed Lever. MUST be in the "UP" position for manual feed.
- FORWARD/NEUTRAL/REVERSE Leadscrew Lever. If Auto-Feed is not required, set to "NEUTRAL"
- HIGH/LOW Lever. Select required speed range.
