In a vertical turning center, gravity reinforces workholding security and process stability. Workpiece weight is directed straight down into the machine foundation and produces no off-axis loads on the spindle. Fixturing is simplified and clamping forces are greatly reduced. The arrangement minimizes the effect of interrupted cuts compared to horizontal lathes while facilitating part handling and increasing the amount of weight the machine can handle. Vertical turning centers often have a smaller footprint than equivalent horizontal lathes. Read More.
