The micron within everyone’s reach

The micron within everyone’s reach

14-Nov-2017 SSP TECHNOLOGY LTD

In Europe the series of publications «…for Dummies» sells like hot cakes. Not that buyers are considered as stupid, far from that …but it is a way to say that these books are addressed to consumers who do not know the subject. They aim to make people informed and efficient very simply. The new modular MVRL 160 vertical honing machine by Pemamo follows this trend and allows everyone to be able to master the micron scale simply and without prior knowledge.

Presented at the EMO, the first vertical machine by Pemamo was a great success. Indeed, for the first time since the foundation of the company it was possible to work with the proven technology of Pemamo (continuous expansion, adjustment to the tenth of a micron, reliability of machines and robustness of the processes) on a machine working vertically. Mr. Decker, responsible for sales, says: “The presentation of the MVRL 160 clearly opened new markets; our arrival on the market with this type of machine has been extremely well perceived by individuals and companies convinced by vertical honing”.

For all applications

The MVRL 160 machine was presented at the EMO in 1-spindle configuration and equipped with a 2-position rotary table. Depending on customer’s needs, this version may be underequipped. For this reason, the company continued its developments and will present a 2-spindle configuration with a 6-position rotary table at GrindTec. Mr. Grimm, CEO , says: “Our customers wished to have more possibilities, for example, roughing-finishing or roughing-brushing in the same machine. The two-spindle version answers perfectly to this desire.” The spindles are totally independent and allow many combinations of operations. The machine is modular and a three-spindle version is also available. Mr. Decker adds: “In addition we offer many possibilities at the level of how we support parts, from a simple cross table to 2, 4 or 6-position rotary tables and even a linear transfer system”. According to the needs, the machines can also be mounted in parallel to increase significantly the number of operations while remaining in a very low foot print.

For everyone to be able to work with such a modular machine, adaptable on request, offering the accuracy of the tenth of a micron is a dream comes true for many companies. What about its manipulation and programming? Mr. Decker says: “Loading and unloading of the machine are performed in hidden time, and changes of set-ups require a few minutes only. The machine is ideal for the realization of batch sizes between 1’000 and 300’000 parts”. This for a reduced investment compared to some «big solutions» available on the market.

“There is no CNC programming to perform; we have developed an expert system that allows anyone to guarantee perfect work within the accuracy of the tenth of a micron. According to machining and production conditions, the operator is guided across a very visual and intuitive interface” adds Mr. Grimm. Pemamo’s know-how is embedded in the system and available to all operators.

Fully integrated compact solution

Regardless of the type of selected MVRL (number of spindles, kind of table), the machine is designed on the same basis and 80 to 90% of the components are identical; it is a good guarantee of reliability. And if Pemamo innovates, it is relying on its long history. Indeed, the inventor of the technology of continuous expansion of tools always uses this in its ultra-modern machines. Questioned about the future, Mr. Grimm says: “When you need to count on holes of small diameters offering micrometric accuracies and moreover with controlled surfaces finishes, honing technology is a must and it is now available as never before with our MVRL 160 modular system”.
