The GROB G550 in use at Csaba Tool Kft.Csaba Tool Kft. from Hungary is an established company in the field of die and mould industries. Since its foundation in 2014, the company has specialised in the manufacture of high-precision aluminium die-casting moulds and plastic injection moulds under the management of CEO Csaba Stallmeiszter. What began with a clear vision is now a recognised company with 30 employees — and an uncompromising commitment to quality, reliability, and on-time delivery.
In a highly competitive market where precision and delivery reliability are crucial, Csaba Tool Kft. relies on ‘state of the art’ technologies to meet the requirements of its customers, around 95% of whom come from the automotive industry. Mr Stallmeiszter said: “Our greatest strength is our precise and accurate way of working. We deliver on time, which is crucial in our industry. But that only works with machines we can rely on 100%.”
When the company was faced with the decision to expand its production capacity in 2022, it quickly became clear that it needed a solution that not only worked at the highest technological level, but one that also offered a reliable service environment. Mr Stallmeiszter continued: “For machines used in tool and mould making, it is essential that they adhere precisely to the required tolerances — and that we receive support very quickly in the event of a problem.”
The choice fell on
Grob — partly because of itswell-thought-out machine concept, which focuses on quality and compactness. After intensive discussions, Csaba Tool Kft opted for the G550 five-axis universal machining centre, and in addition to the basic configuration, the machine was equipped with a special high-precision package which really shows its strengths in the production of complex mould inserts. It took around seven months from the initial quote to the installation of the machine in the hall — a timeframe that was exactly in line with the Hungarian company’s plans.
Consistently good millingSince then, the investment has paid off for the company. László Gogh, production manager at Csaba Tool Kft, highlights the technical details that make the difference. “The machining area is 800 x 1,000mm, with a spindle movement of almost 1,000mm in the Z axis. This allows us to optimally machine inserts of approximately 450 to 500mm — exactly the size we need.”
He is particularly impressed by the spindle design. He continued: “One advantage of this machine is that the length between the spindle nose and the first guide carriage is always the same. This ensures consistently good milling characteristics and optimum stability during machining — which is a huge advantage given our accuracy requirements.”

This enables simultaneous five-axis machining with maximum rigidity and thermal stability. Despite its large machining area, the compact design of the machine ensures a small footprint — an advantage that should not be underestimated in efficiency-oriented production. The side tool changer and optimal chip removal also make the machining centre ideal for machining demanding materials, such as those typically found in die and mould industries.
But it is not just the machine itself that has impressed. The cooperation with Grob has also been consistently cooperative and solution-oriented. Mr Stallmeiszter added: “What we appreciate at Grob is their customer-oriented attitude. Questions are answered quickly and special requirements are taken into account. This reliability is worth its weight in gold in our business.”
For Csaba Tool Kft, the decision to go with Grob was an important step, and one that has already paid off after just a short time. The machine runs reliably, the results are impressive, and the company plans to continue relying on Grob’s technology and experience in the future.
Mr Stallmeiszter concluded: “Everything we have experienced with Grob so far reinforces our belief that we made the right decision. The collaboration works on an equal footing and with the same understanding of quality. For us, this is the basis for a long-term partnership.”
