There are a number of ways to check and align the cutting tool to the spindle centerline. If nec- essary, you can raise the cutting tool by placing steel shims underneath it. The shims should be as long and as wide as the cutting tool to properly support it.
Below are two common methods:
•Move the tailstock center over the cross slide and use a fine ruler to measure the distance from the surface of the cross slide to the tip of the center. Adjust the cutting tool height so it is the same distance above the cross slide as the tailstock center.
•Align the tip of the cutting tool with a tailstock center, as instructed in the following pro- cedure. For this to work, the tailstock must be aligned to the spindle centerline (refer to
Aligning Tailstock To Spindle Centerline in this manual for detailed instructions).
