Progressing to keep moving forward: Mechanical training workshop


This year 2020/2021 has been marked by the arrival of the COVID 19 virus. Health and then economic crisis, confinements and curfews, attestations and teleworking, wearing masks and barrier gestures, etc... This global pandemic has spared no one.

Within the company, we felt that young people were particularly affected by the cessation of classes, the cessation of social life, the difficulty of distance learning, etc.

Borrelly Spring Washers had long had the idea of setting up a mechanical training workshop to enable its young people to progress within the company. 

The extension of its activity to two buildings at the end of 2019 has enabled a reorganisation of its production and the possibility of setting up the training workshop. Taken up with the daily routine, the idea was put aside.

During this year, we recruited a large number of young people, the crisis offered us time, so it was only natural that we set up the training workshop.

We have equipped ourselves with equipment for basic mechanical training and have launched our mechanical training workshop. This allows the young people to learn or acquire new technical knowledge and apply it individually. They are supervised by a professional in the trade.


Read a testimonial about this first mechanical training at Borrelly Spring Washers.

"On 21/04/21, we were able to work alone on the lathe or milling machine.

Personally, I made a chess pawn, here the tower. First I drew the plan of the part and then I thought about how to machine it.

Once on the machine, I installed my blank (ø20 rolled aluminium bar). I straightened the face of my blank by 1 mm. Then I moved it to ø18.

I mounted my centring drill, pointed the end of my workpiece and then drilled with a ø13 drill to a depth of 8 mm.

I mounted my cut-off tool, and machined the shaft of my ø10 lathe leaving a 2mm wide ø12 shoulder.

Then I tilted the lathe's z-axis to 45° to make a chamfer on the top of my lathe.

Finally, I cut my part leaving a 5mm thick base.

On 28/04/21, during this training day, we decided to keep the machines we had used last week. So I did some more turning. To observe the difference in speed of execution of a part already made, the teacher made me redo a chess lathe but this time in copper. So I did exactly the same thing as last week, but with a different material. This time I made the piece much faster than last week. I was able to make the slots for my milling machine. To do this, I clamped my part in the vice with a screw. I attached a dial indicator to the spindle of my milling machine. Then I positioned the spindle axially to my lathe with the pepitas. I mounted a ø4 cutter. I made the 0 in z of my part. Then I machined my slots taking 0.4mm passes."

We are pleased to have been able to conduct this training workshop."
