Bar turning is a material-removal machining technique, also known as subtractive, as opposed to additive. Machining is based on a bar revolving around an axis.
The world of bar turning seems to have originated in the world of watchmaking, and bar turning owes its name to the “collar” of the screws that had to be removed using specific production methods.
Words like décolleteuses, for production machines, or décolleteurs, for bar turning specialists, follow.
Examples of screw machines at Massard
Massard, the Décolletage Solution in Haute-Loire
As already mentioned in our article on customer loyalty, Massard, the bar turning solution in the Haute-Loire, is no accident.
While our colleagues in the Arve Valley are well known for their ability to produce large and very large series, Massard, based in the Haute-Loire region, began specializing in small and medium production runs in the 90s.
Of course, it’s all a question of paradigm, so let’s be precise. Bar turning is generally appreciated for small parts (small diameters) and at Massard, your bar turning solution is based on diameters from 5 to 40 mm; as for series production, it starts at 10,000 parts and goes beyond 30,000 parts.
Massard, the screw-cutting solution for your inserts, parts and mechanical fasteners
At Massard, your inserts are bar-turned parts produced on multispindle lathes with bar feeders.
The multispindle, or “multipass” as it’s known in the workshop, enables us to carry out 6 operations in a very short time, 3 to 5 times faster than on a numerically-controlled machine. This is much appreciated by our customers, to whom we offer very competitive prices. Each tool is placed in the turret, each operation carried out in a precise order, like a never-ending dance, giving the bar turning machine the air of a machine of the future… especially when they arrived in the workshop in the 90s!

The other asset we offer our customers is our bar feeder. Whether single or multi-stage, it allows the machine to be loaded in a way that, once again, optimizes time.
With a simple change of program, our screw machines link your inserts, parts and mechanical fasteners to suit your needs. Our custom-made products are particularly suitable for self-tapping inserts, overmolding inserts and inserts to drawings. Our teams are also available to help you define your needs, if required.
