M4 Post-processing system

Stop compromising on quality or flexibility. The M4 is the revolutionary 2-in-1 finishing system that combines a rotary vibrator and a cleaning centrifuge in a single, mobile unit. Designed as the ideal entry-point into automated post-processing, it delivers professional, repeatable results for small and midsize metal and plastic components—anywhere on your production floor.

Forget complex installations and fixed plumbing. The M4’s integrated process water recycling means it operates entirely without fresh or waste water connections. Simply roll it into place, plug it in, and start achieving perfect finishes from day one. It’s the simplest way to upgrade from manual finishing to automated, cost-effective mass finishing.

FAQs

The M4 uniquely combines two essential pieces of equipment into a single, compact unit: a rotary vibrator for the actual finishing (deburring, smoothing, polishing) and a cleaning centrifuge for processing water treatment. This integrated design saves space, reduces initial investment, and ensures optimal process stability by continuously recycling the water and media.

Yes, absolutely. A major advantage of the M4 is its fully integrated, closed-loop process water recycling system. The machine does not require a permanent connection to a fresh water supply or a drain. This makes it incredibly mobile and allows you to place it anywhere on your production floor with just a standard 400V electrical connection.

The M4 is a highly versatile system suitable for a wide range of mass finishing applications, including:

• Deburring
• Grinding and edge-breaking
• Surface smoothing and homogenization
• Matting (creating a uniform satin finish)
• Polishing
• Cleaning

The M4 is ideal for small to midsize parts with a maximum diagonal dimension of approximately 185 mm. The total batch volume can be up to 23 liters, making it perfect for processing multiple smaller parts at once.

The M4 delivers highest process stability through its intelligent design. The integrated water treatment system maintains consistent water quality, which is critical for repeatable results. The modern, intuitive human-machine interface (HMI) allows for precise control and monitoring of all process parameters

Yes, it’s designed for it. The M4 features a special machine housing for noise protection, making it suitable for use alongside other equipment. Its mobile nature (easily moved with a pallet truck) and small footprint allow for flexible placement without disrupting workflow.

This means the M4 is equipped with advanced controls that can record and monitor process data. This facilitates traceability, allows for the saving of proven recipes for different parts, and enables predictive maintenance, helping you integrate smarter, data-driven practices into your operation.
