COMPANY GROBE
High-tech in the smallest of spaces
The Grobe stonemasonry business has been in the family for three generations. Gravestones account for around two thirds of the orders, one third is work on buildings, but restoration projects and sculptures are also carried out. In-house production has always been very important in Zossen and currently accounts for 75%. Even in GDR times, in addition to new material, old material was also processed and reworked manually and with a surface sanding machine. In order to speed up the sawmill, Karin Grobe’s father converted a Hensel bridge saw built in 1936 for operation with automatic feed and lowering before reunification. After various other machine purchases, a KSL 80 edging machine from Löffler rounded off production in 1998.
The impetus for the modernization of production, which began in 2021, came when the bridge saw broke down for several weeks. Although the outdated machine could be repaired, the entrepreneur realized that sawing with the rotary table was no longer up to date. However, it was also clear that only a customized new machine would fit into the narrow and low halls. The choice fell on an LDZ 2000 from Burkhardt-Löffler. In addition to the individual configuration of the bridge saw, the reliable, German-speaking service was the decisive factor, explains Karin Grobe: „As we have never had any problems with the support of our edging machine for more than two decades, Burkhardt-Löffler was also chosen for the saw.“ While the LDZ 2000 was already under construction, Karin Grobe saw a current KSL 80 at an in-house exhibition and decided to replace the existing edging machine with the current model. To make room for both machines in the workshop, not only was the hall extended and the roof raised in the area of the saw, but the entire infrastructure of electrics, water pipes and compressed air was also adapted. The engineers also adapted the design of the machines to the limited space available. Because the height adjustment of the saw was too high for transportation through the hall, it was hoisted over the roof into the hall in a spectacular way using a truck-mounted crane. Looking back, the master stonemason is pleased to say that it was perfect precision work that went off without a hitch.
The connection of the machine control system to the Diestein ERP program from Dietrich, from which the order is sent directly to the saw, also functions smoothly.
Karin Grobe also opted for a Dietrich solution for the CAD program: „Here too, I always have a German-speaking contact person and I always get help on the same day. This is a service that we have been able to rely on since the 1990s.“ But Karin Grobe is not satisfied with just two new machines: The next investment – a surface sander from Burkhardt-Löffler – is already in the pipeline. There are almost no spare parts left for the existing machine and, in line with her father’s motto, a stonemasonry business must not only be able to saw, but also grind. This makes them independent of material deliveries and offers many processing options.
