When it comes to the processing of steel through to the creation of complete welded assemblies, the family-owned company KTS Technologiepark Stahl has all the necessary machinery under one roof.  The German company, which is located close to the A5 near Karlsruhe, prides itself on being a versatile contact for customers when it comes to contract orders. Because delivery times for laser parts were too long and adherence to deadlines was too erratic, the steel manufacturer invested in a XXXL fiber laser from MicroStep's MSF series with the option for bevel cutting, drilling and tapping. This enables the very large customer demand to be served, especially for components in small batch sizes.

When it comes to processing steel, the company KTS Technologiepark Stahl is a true all-rounder. The family-managed company was founded in 2010 with the aim of combining all technologies for processing steel under one roof. The range of services is diverse: from flame-cut parts, mechanical processing and individual coating to the completion of complete welded assemblies. And thanks to a wide range of know-how, managing director Mario Koch's contracting company sees itself not only as a supplier, but also as a partner and provides customers with advice – for example on issues of process and cost optimization. "A fast turnaround time, quality and fair prices across the entire portfolio are what set us apart," says the managing director, describing his company's strengths. The company was thus able to grow from five to 55 employees within eleven years. In order to take into account the changing conditions and to act even more competitively, Mario Koch decided in 2018 to build a new production hall with around 2000 m² and to invest in a fiber laser MSF from MicroStep with an extraordinary working area, thus introducing laser cutting technology in the company.

Growth with existing machinery limited

The need for laser parts already existed earlier – nevertheless, the company did not initially want to create its own production capacities here. If a customer needed a laser part, it was purchased. However, the difficulties increased: Long waiting times for a quotation, unreliable delivery or the lack of necessary larger sheet metal panels characterized the business relationships with laser service providers. At the same time, the company's own plasma system was operating at almost full capacity. An in-house analysis came to the conclusion that 30 percent of the cutting time of the plasma system was utilized by orders with thin sheets below 12 mm – so the idea to invest in an own laser system was finally born.

Consistent technological development and commitment to Industry 4.0 convince

With the acquisition of the new laser system, emphasis was placed on a wide range of processing options. KTS regularly processes large-format sheet metal panels and also wanted to be able to apply automated weld seam preparations with the laser system. Against this background, a detailed analysis was carried out to find out who on the market could meet these specific requirements. A visit at the Swiss steel and facade manufacturer Rytz AG with a MicroStep reference machine finally convinced Mario Koch of the quality of a MicroStep system, and so the choice fell on the MSF series from MicroStep in a XXXL version. "The bevels had fit tip-top and that without any major adjustments. The precision of the machine is incredible," says the managing director about the laser that was demonstrated at that time.

The metal manufacturer was particularly impressed by the fully automatic ACTG® calibration function, which is part of the standard equipment of MicroStep's 3D cutting solutions and ensures the best possible precision for bevel cutting in the long term. The option to integrate an automatic nozzle changer was also an important purchase criterion. MicroStep's pioneering position on the subject of digitization and the company's commitment to the Industry Business Network 4.0 and the IndustryFusion Foundation also impressed: "MicroStep thinks about what a customer needs and starts developing it. Others wait until the customer whines and complains. It's nice when someone thinks the other way around," says Mario Koch, describing MicroStep's commitment to research and development.

"We are very satisfied with the laser cutting technology we have invested in and are very happy having MicroStep as a partner," says Mario Koch about his decision for MicroStep. The broad processing spectrum includes combined 2D and 3D cutting, drilling, tapping, countersinking and marking. Bevels up to 45° can be realized, and the drilling spindle enables drilling up to 20 mm in diameter and tapping up to M16. MicroStep also implemented the desired color of the machine in traffic purple.

"We are very pleased with the laser cutting technology we have invested in and are very happy having MicroStep as a partner. I would make the same decision for this MicroStep system all over again."

"The quality of the drilling is excellent!"

The necessary documentation for the in-house production control can also be provided easily and effortlessly with the machine. This is because CNC machines from MicroStep are generally capable of digitally providing the parameters used for cutting. Compared to manual documentation with pen and paper, this saves a lot of work in the production process. At the same time, perfect and complete traceability of the manufactured parts, e.g. in crane construction, is an important quality feature of KTS.

The bevel unit is very heavily utilized at the metalworking company and is pushed to its limits. "About 20-25 percent of our components are beveled parts and all possible combinations (V, A, X, Y, K bevel) are handled by the machine just fine. With the new laser, we have also been able to massively reduce the manufacturing time," says Mario Koch, describing the advantages of the new system. Today, for example, a component with a six-meter chamfer is cut on the laser with very little effort. "The quality of the drilling is excellent," says Mario Koch about the drilling unit. Drilling is used weekly for five to ten percent of orders and saves a lot of rework, as this manufacturing process previously had to be done labour-intensively by hand. In the view of the managing director, the entire project process and also the implementation of the new laser system worked great. "No matter at what time, MicroStep has always taken care of emerging challenges with mega power! It's really top level service and when we call, we know that the problem is always taken care of very promptly. I would make the decision for this MicroStep system all over again!", says Mario Koch.
