The vendor stopped stocking the part
The machine works, the part does not. You are left hunting auction listings for a discontinued spindle or bowl scraper, and the units you find have unknown wear.

Where It Goes Wrong
When a Replacement Part Doesn't Fit
These are the four problems we hear most from kitchens, integrators and repair shops running older CL50 units.
02
The replacement shaft wobbles
A shaft turned to ±0.1 mm looks fine on the bench. Once it spins at speed the blade runs out, the cut goes uneven, and the bearing takes the load instead of the shaft.
03
Wrong steel, early failure
Standard 304 on a part that sees food acid and daily washdown pits at the weld line. Six months later you are back to the same repair.
04
One-off quantities, no supplier
You need two pieces, not two thousand. Most shops quote minimums that make a single repair uneconomical, so the machine sits idle.
How We Rebuild It
Reverse Engineering and Machining Used Robot Coupe CL50 Parts
We work from the worn part itself, from a drawing, or from both.
Measure First
Reverse Engineering From the Worn Part
Send us the failed part. We measure it on a coordinate measuring machine, compare the readings against the original design intent, and rebuild a 3D model that accounts for the wear. A worn bore does not get copied as a worn bore.
You get a DFM note within 12 hours listing what we changed and why: wall thickness added where the old part cracked, a fillet radius opened up, a thread changed to a standard pitch that is easier to source.

- 3Material call-outWe tell you where 304 is enough and where 316L or 17-4PH is worth the cost.
Cut It Right
5-Axis Machining for Blades, Shafts and Housings
Blades and impellers need a continuous surface, so we cut them on 16 simultaneous 5-axis centers. Four-axis mills handle the turned-and-milled parts: a shaft with a keyway and a flange, a bushing with cross holes, a housing with a machined face on three sides.
Turning and milling happen in one setup on our 16 mill-turn centers. That matters for concentricity on a rotating part. If the blade seat and the bearing journal are cut without re-chucking, runout stays where the drawing puts it.
Maximum processing size is 4,000 mm, so a full motor housing or a long feed screw is not a problem. Smaller work sits on a Ø400 mm rotary table.
- 15-axis for curved surfacesBlade and impeller geometry cut in one pass, no blend lines.
- 2Mill-turn for round partsShaft seats and journals held concentric in a single setup.
- 3Inspection before shipping100% inspection; dimensional reports available on request.
Material Choice
Which Steel for Which CL50 Part
Pick by what the part touches, not by what is cheapest at the moment.
| Part group | Recommended material | Why |
|---|---|---|
| Blades and cutting discs | 440C, 420 stainless | Holds an edge, resists food acid |
| Shafts and spindles | 17-4PH (SUS630), 316L | High strength, low corrosion in washdown |
| Bushings and sleeves | C36000 brass, 316L | Good bearing surface, easy to re-machine |
| Housings and covers | 6061-T6, 304 stainless | Machines fast, food-safe finish available |
| Brackets and mounts | 1018, 4130 steel | Stiff, weldable, inexpensive to replace |
What We Do
Capabilities Behind Every Replacement Part
One shop for the machining, the finishing and the inspection.
01
5-Axis CNC Machining
Sixteen simultaneous 5-axis centers for blades, impellers and any part with a curved or angled surface that a 3-axis setup cannot reach.
02
CNC Milling & Turning
Mill-turn centers cut a shaft and its features in one setup, so the bearing journal and the blade seat stay concentric.
03
Rapid Prototyping
Test the fit in plastic or aluminium before committing to stainless. Useful when the drawing is still moving.
04
Surface Finishing
Anodizing, electroless nickel, bead blasting, tumbling and polishing. Laser marking down to 1.5 mm character height.
05
Sheet Metal Fabrication
Guards, covers and mounting plates bent and formed to match the original footprint.
06
Custom 3D Printing
Non-structural brackets and spacers printed for quick trials when a machined part is overkill.

FAQs
Questions We Get About CL50 Replacement Parts
Can you copy a part if I only have the worn original?
Yes, that is most of what we do on discontinued equipment. We measure the part on a CMM, rebuild the 3D model, and restore worn features to nominal rather than copying the wear.
Send the part and, if you have one, a photo of where it sits in the machine. The photo often explains a failure that the part alone does not.
What file formats do you need for a quote?
STEP and IGES are best. STL works for geometry checks. A PDF drawing with tolerances and material call-outs is enough to quote if the geometry is simple.
If you have nothing but the physical part, ship it. We will quote from measurement.
Which stainless should I pick for a part that gets washed daily?
316L for anything that sees food acid, salt or repeated washdown. 304 is fine for dry-side brackets and covers.
For a blade that must hold an edge, 440C or 420 gives better wear resistance at the cost of some corrosion margin. We will flag the trade-off in the DFM note.
How tight a tolerance can you actually hold?
±0.005 mm on critical features. We do not apply that across an entire part by default, because it drives cost on faces that do not need it.
Tell us which dimensions matter. The mating bore and the bearing journal usually do. An outside profile rarely does.
What is the smallest order you will take?
One piece. There is no minimum order quantity. A single replacement shaft runs through the same inspection as a production batch.
For volume runs above roughly 100 pieces we will quote dedicated fixturing, which usually lowers the per-part price.
Do you sign an NDA before I share drawings?
Yes. An NDA is available on request, and uploads are handled as confidential under our ISO 27001:2022 controls.
If your drawings are export-controlled or otherwise restricted, tell us at the quoting stage so we can confirm before files move.
How fast can I get parts?
Quotation and DFM analysis within 12 hours. Production can start within 24 hours of approval, and parts typically ship in 3–5 days.
That assumes the material is in stock. A specialty alloy may add sourcing time, and we will say so in the quote rather than after.
Can you match a surface finish from an original part?
We work to Ra 0.2–0.8 μm for fine finishes, Ra 0.8–1.6 μm for standard machined surfaces, and Ra 1.6–3.2 μm as-machined.
If the original has a bead-blasted or tumbled look, we can match it. Send the part and we will compare against our sample set.
