Implant and Small Part Polishing Machines
Discover our automated systems adapted to the medical and luxury industries
Technology?

Polishing is a component of the finishing process for parts made from all types of materials (metallic, plastic, wood, etc.), aimed at achieving a high-quality surface appearance or finish. This surface quality is characterized by roughness, gloss, and shine.
Methods used: Polishing wheels, back-stands.
The part is manually presented on the surface of pads, grinding wheels, or discs made from various materials (cotton, sisal, tampico, rope, synthetic composite fibers, etc.), rotating at high speeds (around 3,000 m/min), and usually coated with polishing paste for mirror-like finishes.
In some cases, particularly for deburring or sanding, abrasive belts with different grain sizes are used.
Mirror Polishing is a finish that requires the complete removal of all defects and results in a perfect glossy polish. The treated surface must be reflective without any distortion of the image.
MEDICAL SIDE
From a medical perspective, mirror finishing is necessary for safety and minimizing friction (e.g., hip cups).
DESIGN SIDE
From a design perspective, mirror polishing often meets very high aesthetic standards associated with luxury or art.

Applications of Our Polishing Machines
The primary field of application for our implant polishing machines is the medical industry (orthopedics, surgery, etc.) but also the luxury industry (watchmaking, art, etc.).
Various applications include:
MEDICAL INDUSTRY
Mirror polishing of hip cups: automatic configuration of polishing spindles from a pad storage system, robot dispensing polishing paste, polishing by the robot using a specific gripping tool.
LUXURY INDUSTRY
Sanding pepper mill caps and bases: retrieving parts from the lathe, sanding, and placing them on a rotating tray for quality control by an operator.

FAQ
Is the cell not too dirty?
A suction system at the spindle level eliminates much of the dust.
Required suction: around 500 m³/H.
The cell should be cleaned once a day, approximately 10 minutes.
What about wear parts?
Wear parts include pads and polishing paste, which have a defined lifespan and are automatically replaced by the robot from the storage system.
Gripping tips or suction nozzles are also wear parts. Similarly, bearings and rotating seals.
Cycle time and autonomy?
The cycle time for the inner mirror polishing of a hip cup is around 8 to 9 minutes.
The cell autonomy is at least 12 hours.
The pad storage system is crucial for cell autonomy in terms of the number of parts. The roughing pad is replaced every 10 to 12 parts, the finishing pad every 20 to 24 parts, and the polishing pad every 30 to 36 parts.
The size of the pad storage must match the required autonomy in terms of part volume.
How many different pads are needed for mirror polishing?
Typically, three pads are required for mirror polishing. The first two steps use polishing paste (with two different references).
The final step is done without polishing paste, possibly with a higher rotational speed to achieve a perfect shine.
