Selection of Adjustable Multiple Spindle Heads


Adjustable Multi-Spindle Heads are available in four layouts. These layouts cover many of the requirements to make closely spaced holes. The common requirement for all adjustable Multiple Spindle Heads is that the pattern be equally spaced from the head's input centerline. This is not to say that other spacings are not possible. It is to say that if you expect the pattern to be centered on the input centerline of the head the pattern must be symmetrical about this centerline. Go to the PAGE showing how to adjust the Multi-Spindle Heads to view an example.
