It depends upon:

  1. Sise of compression machine/model.
    2.Also associated accessories equipment-metal detector and deduster, and
  2. There should have enough area/ space available for easy operation, operator movement, cleaning and maintenance of machine

It depend uopn required number of machine punch/die stations.
For higher number turret area will be large and hence the machine size and vice versa.
