The new multi-surf finisher RMSF 4/800 of Rösler is four times faster than traditional drag finishing machines and fully automated.

A leading implant manufacturer has expanded its product line to include titanium knee implants, necessitating advanced surface finishing solutions. Rösler answered the call with the multi-surf finisher RMSF 4/800, a cutting-edge system that delivers results four times faster than traditional drag finishing machines.

Designed for efficiency, the RMSF 4/800 automates the finishing of critical “box” surface areas while achieving good precision. Process water recycling is managed by the Z 1000 centrifuge, equipped with Rösler’s Advanced digital process water management software, ensuring exceptional process stability and consistent quality.

Key Advantages of the RMSF 4/800 system:

  • Fast and Precise Finishing: titanium and cobalt chrome alloy knee implants undergo a two-stage automated process that slashes cycle times by 75%. Using specialized plastic grinding media, the RMSF achieves surface roughness below Ra = 0.1 µm in just 20 minutes. The innovative system fully automates the previously manual grinding of complex “box” surfaces, enhancing precision and repeatability.
  • Surf-Finishing Technology: RMSF leverages surf-finishing, the most intensive mass finishing technology available. This innovation precisely targets complex surfaces with unparalleled accuracy. Knee femurs are mounted on servo-driven rotary spindles, and treatment occurs in a rotating bowl of grinding or polishing media. Adjustable tilting and rotary motions ensure a consistently flawless finish. Process parameters, such as cycle time and speed, are stored in the PLC for seamless, repeatable operations. Pneumatic clamping and a robot-compatible loading window enable efficient automation.
  • Space, resource, and energy Savings: by eliminating the pre-grinding stage required in drag finishing, the RMSF reduces the number of machines needed from three to two. This translates to significant savings in capital expenditure, energy consumption, and floor space. Additionally, transferring some CNC grinding tasks to the RMSF further optimizes processing times and costs.
  • Digital Monitoring for Maximum Stability: Rösler ensures process stability with a visualization module integrated into the RMSF control system. Operators can monitor each process stage in real-time, minimizing errors and maintaining high-quality output.
  • Advanced Process Water Management: the Z 1000 centrifuge recycles and manages process water using Rösler Smart Solutions’ “Advanced” software. This system continuously monitors up to 14 parameters, such as pH levels and microbiological loads, providing instant alerts and actionable recommendations when values deviate. Even operators with minimal training can maintain optimal process conditions, ensuring consistent product quality while reducing water and compound consumption. Long-term data tracking also supports quality audits and documentation needs.

So, the RMSF 4/800 represents a significant leap in surface finishing technology - combining speed, precision, and sustainability, while reducing energy use, resource consumption, and manual intervention.
