Southbend SB1027 owner manual To tram the spindle to the table, Tools Needed Qty

For Machines Mfg. Since 8/09 O P E R A T I O N Model SB1027

Tools Needed	Qty
Dial Test Indicator
(with at least 0.0005" resolution)	................... 1
Indicator Holder
(mounted on the quill/spindle)	1
Precision Parallel Block
(at least 9" in length)	1

Note: A precision-ground plate can be substituted for the parallel blocks. Keep in mind that the farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be.

To tram the spindle to the table:

1.DISCONNECT MILL FROM POWER!

2.Prepare the mill by performing the following tasks:

•Stone the table to remove all nicks and burrs, then clean off all debris. Verify the table is clean by running your hand over the top of it.

•Position the table for the milling operation you intend to perform after the tramming—preferably centered to the saddle.

•Tighten any table, knee, quill, or ram locks that should be tight during the intended milling operation.

3.Place the parallel block underneath the spindle.

4.Install the indicator holder into the spindle or onto the quill, then mount the indicator onto it so that the point is as parallel to the block as possible (see the illustration in Figure 28 for an example).

5.To measure spindle alignment along the X-axis, place the parallel block directly under the spindle and indicator across the length of the table, as illustrated in Figure 29.

Note: If you must re-position the quill or the knee to accommodate the above step, then review the tasks in Step 2 to make sure the mill is properly prepared for the tramming operation.
