Rafi Robotiques et Machineries
Three-year workshop apprenticeship across CNC repair, industrial machinery restoration, 5-axis robotic welding systems, and PLC-based production troubleshooting.
2020 - 2023 | Mechanical repair, CNC machining, robotics, automation
Duration
3 years
Long-form industrial exposure.
CNC stack
840D / 611
Siemens Sinumerik and Simodrive.
Robotics
5-axis
Welding robot fabrication work.
Automation
PLC
Machine recovery and logic repair.
Workshop scope
Industrial context
The work took place in a practical machine-repair environment where downtime, missing programs, worn mechanical parts, and urgent client constraints had to be handled directly on industrial equipment.
Engineering value
This apprenticeship built hands-on judgment across mechanics, CNC controls, robotics assembly, sensor integration, PLC debugging, and machine restoration before the academic engineering cycle.
Industrial interventions
Machine restoration
Sharmaann horizontal boring machine repair
Diagnosed worn worm gear pinions, supported disassembly, helped manufacture custom bronze replacement parts, and participated in precision reassembly to restore machine reliability.
Mechanical diagnostics, custom component manufacturing, tolerance control, precision assembly.
Robotics fabrication
5-axis welding robots for Armasteel
Contributed to two 5-axis welding robot builds with extended displacement, infrared path tracking, and motion-speed adjustment according to welding angle.
CAD support, mechanical assembly, sensor integration, robotic motion concepts, fabrication methods.
CNC recovery
Geminis CNC lathe repair for Longofer
Supported diagnosis of Z-axis immobilization and alarm faults, then helped recover the operating system, restore machine parameters, and reintegrate Siemens Sinumerik 840D with Simodrive 611.
CNC diagnostics, OS recovery, parameter configuration, system integration, machine commissioning.
Automation recovery
Matissar spring assembly machine reprogramming
PLC debugging, industrial troubleshooting, logic recovery, client-facing repair work.
