Celikform Gestamp launches hinge production four spindle machining center from LiCON

30.12.2023

Celikform Gestamp has successfully launched the production, using the technology and expertise of Edscha, a leading company for hinge production and also member of the Gestamp group. At Technosab, a brand new industrial area in outer Bursa, a new production was installed. The new hall is as big as 17000 m². The line produces hinges for a leading passenger car maker. All steps from the forged blanc to the ready to install hinge set successfully started operation. Before the hinges are assembled in an automatic assembly line, the blancs are machined on two four-spindle machining centers. For this core process, Celikform Gestamp relied on LiCON as supplier for the machining centers. As a leading and technology driven German company, LiCON provides a wide range of single-, twin- and four-spindle machining centers.

Three strong points

• Maximum production on minimum floor space
• Energy saving
• Robust machines with powerful spindles

Milestone project

Mustafa Ugur Alayci, explains the decision for the LiCON machines: "The LiCON four-spindle LiFLEX IV 244 DL DT B00 convinced us. With four spindles working parallel on each machine, only two machines were required for the entire volume." As Business Development Manager at Celikform, he drove this project for Celikform. It was a milestone project for Celikform. Coming from the sheet metal fabrication, the machining was an additional process, opening doors for further business. Besides the machining centers, all the peripheries had to be installed, such as CMM and tool set-up rooms.

With all these challenges ahead, LiCON was chosen as partner. Celikform selected sixty years of experience. "These machines are robust and strong, with approx. 18% more spindle torque than the alternatives," explains Fatih Acet, the Production Technologies Manager.

Maximum production on minimum floor space

Each four-spindle machine has two bridges on the double trunnion, which allows loading parallel to machining. Eight different part numbers are loaded to the bridges of the two machines. No manual changeover is required. With each cycle of the two machines, four passenger cars can be equipped with the door hinges. The smart design of the clamping fixture allows for a compact arrangement.

The LiCON department designs, builds and tests clamping fixtures inhouse. Many customers appreciate the turn-key solutions from one hand. LiCON supplied the machine fit for the process, i.e. with fixtures, tooling and process run-off.

With a floor space of only 50 m² including the manual loading area, the four-spindle machines use almost no space relative to the high production volumes.

Energy saving

Energy saving becomes more and more important. Both machines are equipped with minimum quantity lubrication (MQL) in lieu of the traditional coolant. This technology is known for two decades now and more and more producers take advantage of up to 40% energy saving and longer tool live.

Successful project

All the challenges were mastered, and new standards set in the production of passenger car hinges. Celikform is now recognized as a reliable supplier for such parts by leading car manufacturers. " With LiCON, we have found the right partner for the machining" says Semih Kurt, Purchasing Manager.
