PrimeARC profile bending machines – from design to realization
We invite you to an interview with Marek Glet and Łukasz Żarczyński, designers and constructors of the PrimeARC series of Polish three-roll bending machines. It includes: where did the idea for this type of machines come from and what made the bending machine a favorite machine in many enterprises.
How to start? Where did the idea: “let’s design a bender!” come from?
ŁŻ: We came up with the idea in our free time. Over the years, we have launched machines from many global manufacturers and at first we began to notice that they were repeatedly limited. What was missing on the market was a flexible one that would combine a solid plug with built-in CNC control and at the same time be available locally – without import devices from the other end of Europe. So we thought, “Since we’re designing everything around anyway, why not create our own machine?” I took the idea of PrimeARC.
From the beginning, you had specific design goals – what the machine was supposed to do and for whom?
MG: Yes, we had clearly defined goals. The product was intended to be addressed to customers requiring the highest quality and precision of operation. We wanted to create a three-roller bending machine that would have advanced CNC control allowing the production of the most geometrically complex shapes. We also realized that for customers to be happy to use the machine and be satisfied with it, the control must be intuitive to use and allow for the quick implementation of new details into production.
ŁŻ: It was also important that we wanted to create a bending machine based on components available in Poland and with a fully proprietary CNC control, combining the best features of other machine controllers. Moreover, we wanted a device that would be industrially adapted to full-shift work, but would also work well in a small company where simplicity and reliability are important.
What was the most difficult in the initial design phase?
MG: In the initial design phase, we spent a lot of time discussing possible concepts for both general solutions – regarding the entire machine – and very detailed specific components. We had to find a balance between modern solutions and costs and availability of materials. We spent a lot of time testing different concepts to make sure they met our goals.
ŁŻ: An example of finding such a balance was the integration of the mechanical system with the control system. On the one hand, we designed a rigid, solid structure with components that are available locally – on the other, we had to connect it all with electronics and software. It was really demanding to make everything work precisely and smoothly.
What about implementation? What does the process of creating the machine look like?
MG: The process of creating a machine, skipping the concept and design stage in CAD programs, starts with placing orders for all the machine’s components. By this I mean all mechanical, electrical and electronic components. We attach great importance to ordering parts from local suppliers with particular emphasis on the highest quality of workmanship. We choose the best global manufacturers as suppliers of electronic components that are not produced in Poland. After completing the entire order, we start building the machine, which is actually one of my favorite stages. The construction stage itself takes several days, and culminates in operational tests and the commissioning of the machine for bending tests for new customers.
Were all design assumptions achieved?
MG: We are very satisfied with the project and I can say that we managed to implement all the key design assumptions. Moreover, during work on the machine, further ideas for certain modifications and improvements to increase the level of advancement of the machine appeared, which we also implemented.
ŁŻ: Definitely yes – and even more. The PrimeARC CNC project exceeded our expectations in terms of precision and repeatability. And the best answer to this is the opinions of our customers, who often say that it is their favorite machine in the plant – because it is intuitive, fast and easy to program.
What are the next design challenges facing you and PrimeARC?
MG: The first, continuous and constantly undertaken challenge is the development of CNC software in order to increase its attractiveness for customers and intuitive operation for machine operators. The second consistently implemented activity is the design of new sets of equipment for bending increasingly complex cross-sections provided to us by our clients.
ŁŻ: We are also working on two new models of bending machines. PrimeARC 65 CNC – it will be a machine for much heavier applications. PrimeARC NC Basic, on the other hand, will be a more budget version, for those who do not need a full CNC.
MG: We are still active at Primetec, and of course, please contact us if you are interested in PrimeARC solutions! At this point, I would also like to point out that the option we offer to carry out bending tests at our company’s headquarters is an aspect that distinguishes Primetec from other companies offering three-roll bending machines, where tests are often performed at the customer’s premises only after purchasing the machine. Thanks to this, we can offer solutions tailored to individual requirements, and the customer can be sure that the selected solutions will fully meet his expectations.
We design and build highly advanced profile bending machines with CNC control. We provide modern equipment for bending machines and professional technical advice.
