Escofier’s Flex machine series features a modular design and is well-suited for cold rolling processes used with dies. Machine bases are available in M and L sizes, accommodating a range of workpieces. The maximum rolling force of the cylinder is between 5 and 60 t. One cylinder, either hydraulic or electric, ensures the symmetrical movement of the slides, the company says.
The machine features two movable carriers controlled by the cylinder. Ground guides are designed to ensure carriage movement accuracy. The spindles are rotated by reducers or direct-drive shafts, and spindle diameter is adapted to rolling dies and applications. Movements are controlled by PLC, numerical axis or CNC. Options include force and position control systems for the gear-finishing process as well as taper and helix adjustment.
The machines enable in-feed, through-feed and forced through-feed uses, and they are capable of multiple rolling operations in the same cycle. According to the company, they ease production change-overs, and rolling station accessibility enables specific part fixture and automatic loading integration.
Applications include thread and knurl rolling, high-precision spline rolling, gear roll finishing, sintered part densification and tubes-specific form rolling. The machines are designed for the automotive, aerospace, railway, medical and construction industries, among others.
