NEW GENERATION
REPKON RFM - SERIES

As a proven method for the production of rotational symmetrical seamless high pre-cision parts, flow forming ranks amongst those metal forming technologies which are increasingly gaining in importance. Reserved for many years for use only in the aerospace and defense technology this method opens up new avenues for application in the industries of the future.

REPKON has designed and engineered a machine that broadens the applications. In a winning combination of long proven experience in metal forming with high-tech and state of the art solutions we de-veloped a machine meeting the high cus-tomer specific requirements concerning productivity and return on investment.

 
Enclosed symmetrical flow of force

The outstanding technical highlight of this machine is the fixed machine tool table with the three radial rollers and the two moving headstocks. With the use of high precision ball-screw spindles symmetrically pulling the headstocks to the robust machine tool table an enclosed flow of forces develops. This machine design achieves because of its embedded stability shorter cycle-times with ultimate precision of the formed parts.

The REPKON RFM Series is the best solution for the production of cylindrical high precision seamless parts. The RFM Series covers a diameter range of 40 mm to 1.500 mm and a length of the finished part between 200 mm and 15.000 mm. Within this basically data REPKON customizes every machine to the specific requirements of the customer.

Outstanding design advantages

  • All ball-screw spindles for moving the two headstocks are positioned symmetrically round the work-piece to exclude bending loads on the linear guiding system.

  • All movements of the machine are done by high precision ball screw spindles dri-ven by electric motors. The machine uses no hydraulic drives gaining advantages in energy consumption, noise level and clean environment.

  • The radial axes are driven by state of the art torque motors guaranteeing highest torque at low revolution of the motor. They are guided by maintenance-free special bronze guide-ways.

  • Both spindles are synchronized driven by AC-motors broadening the spectrum of producible parts.

  • The axial position of the radial rollers can be CNC controlled under load.

  • The electrical cabinet is integrated into the machine-bed resulting into a fast in-stallable “One-piece” machine.

  • For high speed flow-forming the machine is equipped with a special cooling device and an inside cooled mandrel.

  • All welded construction is built from ST 52 steel and stress relieved after completion.
