Youthful experimentation was yesterday - PAWA-Tech GmbH
Automation was an issue from the outset. “I built the first automation system for the C 250 U myself,” says Paul Walczok proudly. “A lightweight robot, a few control components, with the charm of youthful experimentation.” But somehow, it worked. “It taught me what truly matters: Chip removal, coolant supply and, of course, above all else, process reliability.” In 2023, he took a major step: Acquiring a C 22 U equipped with an adapted HERMLE robot system RS 05-2.
For almost a year now, the automation system has been operating unmanned overnight. During the day, the qualified employees run the three machining centres in two shifts. At night, a robot colleague operates the C 22 U. PAWA-Tech now produces batches of ten or more components fully automatically. “This has proven especially effective for workpieces with long runtimes. It keeps the machine busy all night,” says the company founder.
A 6-axis industrial robot handles blanks weighing up to ten kilograms, changes different grippers fully automatically and can thus flexibly move various components. PAWA-Tech uses a five-drawer storage that can hold 50 to 90 workpieces on each level. The universal dies can be quickly adapted to changing components. The robot system RS 05-2 has a very compact design, only requiring an installation area of around two square metres, and allows operators unrestricted access to the working area and rack storage. It is fully integrated into the HERMLE environment and can be operated via a touch pad. The HERMLE “Automation-Control-System” (HACS) shows, for example, an overview of the orders, the sequence plan as well as tool data and prioritisation. Thanks to the long-stroke clamping device and the drawer system, various component sizes can be clamped without the need for conversion.
The spindle runtime has doubled since the robot’s introduction. While the conventional machines operate in two shifts, the C 22 U with the RS 05-2 also mills overnight. “Today, 24/7 is only possible with automation,” Paul Walczok asserts.
Why does Paul Walczok place such consistent trust in HERMLE? He does not think twice before answering. “Because it works. The machines are extremely reliable. And should we need to report a fault, a replacement arrives the very next day. The second reason is the high precision of the machining centres. “In motor sports, we work with tight tolerances and mill complete cylinder heads on the C 32 U – including channels and fits,” explains the managing director. Depending on the component, this process can take up to a full day. “Precision on five axes – that is our business.”
PAWA-Tech exemplifies modern production: Precise, flexible and well organised. The blend of machining centre, robot system and the reliable HERMLE service makes all the difference. Paul Walczok and his team can count on this. For motor sports and other demanding customers, this means more than just words. It is about components that fit perfectly, processes that run smoothly and machines that never break down overnight.
