The Wickman 2 14 6 Spindle Automatic has the standard Wickman design features, proven in large scale production environments across the globe, including the 'no cam change. This ensures smooth running at fast production times, whilst maintaining consistent accuracy of the produced components. Multiple Spindle Automatic Lathe: Multiple spindle automatic lathes are machines which can produce larger work pieces than single spindle automats. The principle advantage of the multi spindle automat is that it has a tool slide working on the jobs on all spindles simultaneously and hence the time for producing a piece is the time for the. Multi Spindle Automatic Lathe For increase in rate of production of jobs usually of smaller size and simpler geometry. Having four to eight parallel spindles are preferably used. Multiple spindle automats also may be parallel action or progressively working type.
