Transfer machine

A transfer machine for cold plastic deformation and/or chip removal of at least one tubular profile, comprising:

• a base for resting on a base plane;
• a mounting table fixed and arranged orthogonally to the base plane;
• a rotary table facing the mounting table;
• and
• a plurality of electromechanical work units installed on said mounting table,
• wherein the rotary table comprises a plurality of work stations, wherein each work station of said plurality of work stations comprises a vise for clamping the at least one tubular profile,
• a plurality of housing seats being formed in the mounting table, wherein each housing seat of said plurality of housing seats faces a respective work station and is suitable for accommodating an electromechanical work unit of said plurality of electromechanical work units, each electromechanical work unit comprising a first advance group, wherein the first advance group of each electromechanical work unit comprises:
• a first advance motor, wherein said first advance motor is electric;
• a first advance recirculating ball screw moved by the first advance motor and extending along a first advance screw axis orthogonal to the mounting table;
• a first advance nut engaged by the first advance recirculating ball screw and translatable along the first advance screw axis;
• and
• a first tubular stem extending between a first stem proximal end and a first stem distal end, the first stem proximal end being engaged to and made integral with the first advance nut, the first stem distal end being suitable for defining advancement and/or positioning of a first tool holder element,
• wherein the first advance motor is a hollow shaft motor, and
• wherein each electromechanical work unit comprises an external covering frame made of anodized aluminum, the external covering frame allowing obtaining electromechanical work units light enough to be installed cantilevered in the housing seats of the mounting table.
