Your turned parts in large series,
at the right price
YOUR CHALLENGE
In large series, everything hinges on unit price and consistency
The right turning shop, the right machine (cam or CNC), the right material, the capability that holds over 100,000 parts: every detail weighs on your cost and quality.

page — the two offerings are complementary.
Swiss-type lathe (sliding headstock)
Tour poupée mobile (Swiss)
Pièces longues et élancées, petits diamètres, haute précision. Le cœur du décolletage.
Fixed-headstock lathe
Pièces courtes et de plus gros diamètre, reprises intégrées.
Multi-spindle (CNC and cam)
Très grande série, cadence maximale, coût unitaire le plus bas.
Single-spindle CNC lathes

Perçage transversal, fraisage, taraudage, roulage de filet, moletage.
Finishing
Deburring, washing, vibratory finishing, optical sorting, packaging.
MATERIALS
Grades with good machinability for large series — with or without lead depending on your regulatory constraints.
Free-cutting steels
Heat-treatable steels
C45, 42CrMo4, case-hardening steels 16MnCr5 / 20MnCr5.
Stainless steel

Aluminum · Bronze · Copper
Alu 2011 / 6262, bronzes, copper (connectors).
Titanium and specials
for automotive, electronics, drinking water or medical, prefer
- lead-free
- grades. We guide you according to the applicable directive (RoHS, REACH, ACS).
- TOLERANCES AND INSPECTION
- Tight diameter tolerances (IT6–IT7, down to a few µm)
Fine surface finishes controlled in turning
- Rolled threads (stronger) or cut threads
- High output without dimensional drift
- Inspection
- Statistical control (SPC) and Cpk capability

Cut unit cost from the drawing
Machinable material
A well-chosen free-cutting grade increases output and lowers the price.
Limit secondary operations
Each off-machine secondary operation adds cost. Group them.
Useful tolerances
Only tighten functional dimensions. The rest in ISO 2768.
Rolled threads
Low-resistance noble contact
Prefer rolling over cut threading: stronger, faster.
Reasonable slenderness
Stated volume
Give the real annual quantity: it determines the machine and the price.
