FLEX

General Features
As is characteristic of all BAHMÜLLER series, the FLEX has all expansion options, between internal grinding, combined grinding and external grinding. The use of a robot within the machine room is particularly innovative and beneficial.

Consistent alignment to standardized axle arrangement relationships and selective tool arrangements result in cost-efficient and retrofit-flexible solutions for a variety of applications.

Your Benefits

Further expansion of the standardization of the basic setup

  • 80% of the basic setup between internal grinding, external grinding in the chuck and external grinding between centers are identical
  • this establishes the basis for "re-use" projects

Pre-defined and pre-designed, fixed arrangement relationships in the project-specific expansion of the basic setup

  • significantly shortened project through-put times (delivery time reduction by 30%)
  • lower risks through lower project-specific proportions
  • higher common part rate

Standardized internal loading by robot

  • reduction of individual engineering proportions in the project
  • parallelization of commissioning of the loading system through simulation options
  • reduced failure risks through standardized mechanisms (robots)
  • remote diagnostics capability

Optional integration of sub-systems within the machine

  • loading by internal robot
  • integration of up to two systems (pre-measurement systems, post-measurement systems, brush systems and small pallet systems)
  • fully autonomous machine incl. pallet handling with optional post-measurement station without external peripherals

Simplified retrofit flexibility

  • general structuring of the series enables extensive dismantling and modification options
  • use of robot for internal loading enables simplified upgrade to additional work piece variants

Modular interface to external Systems

  • unified transfer to external rail, belt, bulk material or pallet feeds
  • faultless operation through debugged interface
  • simple upgrade to higher autonomous systems (start-up orientation)
