MANUFACTURING PANELS

How it’s done

A little look behind the scenes is always interesting. Find out here how the production of operating panels and door locks is done at KRONENBERG. Why do we like to show that? As we are proud of what we may do every day for our customers around the world. And because a hidden champion is allowed to show what goes on every day behind the walls at Kurt-Schumacher-Straße 1.

After the CAD configuration of the operating and display panels in the sales department, the V2A cut sizes are made in our sheet metal processing center. All punchings are made here. The turret punching machine used at KRONENBERG has a punching force of 200KN and includes a tool turret for 51 different tool stations in total.

In the next step the pre-cut sheet metal is transported to the laser machine. The larger cut sizes for which no punching tools are available are made here, e.g. the outer contours of the panels or larger cuts for floor position displays and information fields.

The laser cutting center at KRONENBERG has a laser power of 2.5 KW and a traversing range of 2,520 mm (X), 1,550 mm (Y) and 300 mm in (Z).

The laser was equipped with an optical measurement system to ensure a perfect link between the punching and laser machines.

In our engraving room company logos, lift symbols and common texts are milled into the already punched and cut stainless steel sheets. These letterings are then permanently filled with color.

In order to increase the stability of the car operating panels / panels, they are folded on the CNC-controlled bending machine. With a pressing force of 1300 KN and a bending length of 3m, KRONENBERG can produce floor-to-ceiling panels with a sheet thickness of 3mm. Control panels are also bended on this machine according to their processing.

Manufacturing DOOR LOCKS

The rough cast housings for our door locks are prepared for final assembly in our FH4000 machining center. For this purpose, two cubes are alternately fitted with untreated housings and moved into the machining center. During the processing of the equipped cube, the removal and replacement of the other cube are made in parallel.

The finished housings go together with the prefabricated locking bolts and other components for the door locks (such as toothed levers, roller levers, locking pins, contact inserts, etc.) in the final assembly.

There the door locks are finalized according to customer’s orders and component testing and quality control is done.

for both processes:

In our dispatch warehouse the final material is removed and the QR codes are scanned so that we are able to inform our customers of a delivery status just in time.
