Multi Spindle Drilling and Tapping machines are normally high volume production machines. Normally the Multi Spindle Drilling and Tapping machines can perform Multi Times as many as spindles, because the Spindles are in multiples and the operation done in multiple passes, it can be done in one pass. for Example if you want to do 2mm or 25mm Drill in 4 nos to 10 nos or even more. if single spindle takes 1 minute to do 6 holes, multi spindle can do it 10 seconds. and simultaneously it can also do the Tapping operation, which theoretically does not consume and time. So if your product is manufactured by multiple manpower in multiple machine, all that can be brought in one machine with single operator. This will result in high Volume production along with cost cutting and more profits. https://www.youtube.com/watch?v=FsoqmD-0Bbc
