Automated oil removal from chips increases efficiency

As part of a strategic realignment, Monnin SA was looking for an automated solution for swarf oil removal. The solution needed to be technically flexible, operationally reliable, and require minimal manual effort. The challenge: three types of swarf, three different oils, and stringent requirements for cleaning, recirculation, and integration. Discover how the Rimann team implemented these requirements.

MONNIN SA HAS BEEN PRODUCING PRECISION SINCE 1946

Located in the heart of the Bernese Jura, a region known worldwide for its microtechnology expertise, Monnin SA has been manufacturing high-precision screw-machined components for the watchmaking and related industries since 1946. This traditional company combines craftsmanship with technological progress, focusing particularly on efficient and clean production processes.

GOALS FOR THE NEW OIL REMOVAL SOLUTION

Monnin SA defined four key requirements for the new structure:

1. Collect and process three different swarf types and oils separately.
2. Achieve fully automatic oil removal from the swarf with Rimann's Aryma 51-1, eliminating manual handling.
3. Maximize the recovery, purification, and reuse of cutting oil.
4. Seamlessly integrate into Monnin SA's existing infrastructure.

A complex requirement, ideal for a flexible solution from Rimann.

THE SOLUTION: FCM 65 FOR AUTOMATED AND ROBUST PROCESSES

In collaboration with its partner company FAMA, Rimann implemented a system centered around the FCM 65 centrifuge, which was custom-tailored to the specific needs of Monnin SA. The technical foundation includes a drum diameter of 650 mm, a capacity of 130 kg, and a speed of 720 rpm. The system is complemented by coordinated, customer-specific peripheral components:

1. Lifting and Tilting Device: For automatic drum loading, adapted to Monnin's swarf trolleys.
2. Three Separately Controlled Return Pumps: For oil separation.
3. Shuttle System: Featuring three defined discharge stations and fill-level monitoring.
4. 10" Touchscreen Control: With an intuitive interface, data transfer via USB and Ethernet, and operation via tablet.
5. Safety Features: CE-compliant safety devices and a robust design for 24/7 operation.
