Our client is a major provider of industrial solutions for the plastic industries.
Tested products: aluminium profiles (door frames and thresholds)
The door frame is the door part which is fixed on the wall and supports the door sash. A door threshold is the lower transom of a door frame, aiming at protecting the inside of a room from exterior infiltrations.

Machining holes and milling aluminium profiles (door frames and thresholds) in an automatic way.
Our engineering team fully complied with the client's specification. This one notably wanted to have a 3-axis machining centre that was simple of use and easily programmable by any operator, included by non-machinists.
Solution and result
The LF Technologies team provided the technical solution, by developing a machining centre with several removable spindles, each one comprising a different machining tool, so as to carry out drilling with diverse diameters and adapted to each profile.
The profile is manually placed on a removable table fitted with a precise positioning device and a locking that are controlled by the operator.
The machine is also equipped with a 3-axis (X, Y, Z) digital command which perform 3 movements:
- The profile is mounted on a cart that moves on a twin rail for a 3-meter run, this movement is applied by a ball screw with nut (X-axis);
- A rigid frame with vertical plane and horizontal movement is mounted on a fixed chassis which is located in the middle. The frame slides on two precision linear guides and is driven by a ball screw with horizontal axis (Z-axis);
- Another frame with vertical plane and vertical movement slides on the last frame with horizontal movement. It is driven by two synchronized ball screws with vertical axis (Y-axis).
According to the application the operator programmed, the electro spindles perform machining on the aluminium profiles, with the possibility to make movements in X, Y, Z. The machining centre is fitted with 2 software applications, which indicate the tools position in X, Y, Z and also allow storing unlimited different machining programs. The software applications are very intuitive and simple of use, as required by the client.
