Machining workshop

Joseph Martin has a well-equipped, modern and efficient machinery.  We master our manufacturing processes and guarantee a best quality production, in average and large series, from diameters 0.5mm up to 32 mm.

A steady rate of investments and a good partnership with the machine builders enable us to boost our technological lead and to maintain a high productivity level.

We modify and adapt our production means so that they meet our customers specific requirements.

Machinery :
42 cam-operated multi-spindle turning lathes (6 & 8 spindles)
32 CNC driven multi-spindles (6 & 8 spindles)
13 CNC- mono-spindle machines

Assembly and automatic control of machined parts

Always looking for the 0 PPM goal, we develop and invest in automatic control solutions. These may be customer dedicated or flexible machines, enabling us a continuous adaptation to your needs.

We implement following controls :

  • Camera controls (aspect)
  • Dimensional checks (by laser contact or camera)
  • Eddy current method
  • Sealing and leakage tests
  • Draft control

In order to meet your various technic constraints, our range of assembly machines (crimping, press-fitting, torque and draft controls) enables us to supply complete subassemblies.


Cleanliness – Deburring

We ensure and guarantee the required cleanliness levels by taking special care of your parts during machining, deburring and multistage washing. The size and gravimetry of particle contamination on delivered parts is mastered and followed-up day per day.

Cleaning equipments of machined parts

Joseph MARTIN has washing means equipped with ultrasounds, efficient filtration systems as well as an in-situ corrosion protection solution. Components are washed in bulk or carefully stored in trays.

  • 10  AMSONIC washing machines (A3 solvents or soap cleaning agents)

Tribofinishing of machined parts

We have some tribofinishing machines that enable us to proceed to deburring or polishing operations.

In order to preserve the environment, we treat the released effluents through our filtration base.

  • 10 tribofinishing machines
