Turning

This department, where all the production is born, represents Alintech’s heart. We are able to produce mechanical components with sliding headstock and fixed head CNC lathing and multi-spindle turning.

For example, we make conical or straight knuckles, blind or through holes, external or internal threads, keyways and tongue.

For example, we make conical or straight knuckles, blind or through holes, external or internal threads, keyways and tongue. Thanks to even more sophisticated numerical control machines, the department has renewed itself in order to satisfy the increasingly numerous requests of customers operating in the field of hydraulic pumps, gearmotors, rack actuators and where molded elements, that require maximum precision, are used.

Machining of die-casted rotors with shaft

The majority of Alintech’s production is concentrated in this area, equipped with advanced machinery and movement systems for cutting-edge parts. In fact, it represents the technological and development center of the company itself.

Inside we carry out assembly, straightening, turning and grinding of die-cast shafts thanks to the use of fully automated turning and driving islands, inside which it can found various type of anthropomorphic robots.

Machinery

N° 4 shafts turning islands

Each island consists of 2 lathes and 1 robot for loading, unloading and automatic piece control.

N° 2 rotors assembly islands

Each island is completely robotized.

Others processes

In order to maintain high standards, we also carry out finishing processes, such as:

  • millings;
  • external metric, gas, american and whitworth threads;
  • lapping smooth shafts or gearworms;
  • smooth or crossed knurling;
  • chamferings for assembly with rotors.

Finally, each piece, before being packed for shipment, undergoes washing with perchlorethylene in a closed chamber, as well as the application of dedicated anti-oxide protection.
