| Spindle Selection Procedure 1. Determine the Power and Speed requirements for the application. Refer to the cutting data found in tool catalogs. For assistance, consult the SETCO Application Group. 2. Locate the Spindle Speed (rpm) on the chart and follow the line up until it intersects with the required Power (hp). 3. Continue up until it crosses the Spindle Size (model) line. This line is the minimum spindle size. 4. Verify that the Tool Overhang, measured from the spindle nose, falls within the maximum for the spindle. 5. For finish bore applications, verify the front spindle bearing is as large as the bore to be machined. |
