Checking Machine for Crankshafts 350 MBRK, 550 MBRK, 650 MBRK - Schenck Bulgaria

  • Quality control of crankshaft castings or forging and finish machined crankshafts
  • Manual loading and unloading
  • Expandable with a correction unit

Design

Machines with horizontal rotor axis and rugged sub-critical balancing unit. Belt-drive for the crankshaft and end-drive for the cage. Support of the crankshaft according to requirements and task, between spindle cones or in a cage.
Yстройство

Range of appliation

Unbalance measuring machine for passenger vehicle and commercial vehicle crankshafts of various sizes. Can be used in production for checking production quality of mass-centered castings or forgings and/or of completely machined crankshafts.
Transport of the shafts either manual or by corresponding lifting device.

Special features

Machine concept expandable through modular design. Universal belt-drive or end-driven cage, both require no adapters.
Rotor support between either spindle cones or in a cage with large setting range for crankshaft castings or forgings.
