Project Description:

Fully automatic laser trimming cell for rotary shaft seals (RWDR)

Development of a fully automated 'stand-alone' manufacturing cell for the laser trimming of radial shaft seals from bulk material. Unlike inline solutions, this system manages the entire process: from feeding and singulation, through precise double-trimming (outer and inner diameter), right down to sorted output. The process guarantees a burr-free cut at two positions in a single setup.

Technical Data:

• Application: Radial shaft seal (RWDR) trimming on the outer (30 mm) and inner diameter (20 mm).

• Material Feed: Bulk material via vibratory bowl feeder & linear conveyor.

• Laser Source: Fiber laser.

• Beam Delivery: Fiber optic cable with integrated collimator.

• Optics: Beam diameter 7 mm (input), focal spot diameter < 0.2 mm.

• Cycle Time: Approx. 7 - 10 sec. per component.

• Handling: Pneumatic pick-and-place system with a high-precision clamping fixture.

• Cycle: Parallel feeding and processing for minimized cycle times.

Skills & Deliverables:

• Special Purpose Machinery

• 3D Assembly Design & Kinematics

• Design for Manufacturing (DFM)

• Project Support from Concept to Commissioning

• Autodesk Inventor

• FEM Simulation

• Mechanical Engineering Calculations

• 3D Printing (Prototyping)
