The youngest member of the SF series is our SF-HP for heavy and large workpieces in various industries: for example, aviation, food industry, mold tools, mechanical engineering, energy, oil and gas industries.
What is new and unique about the SF-HP and how does it differ from previously available vibratory finishing technologies?The uniqueness of this machine lies in the fact that heavy and large components now benefit for the first time from proven OTEC Streamfinish technology and expert support in process definition. The key difference compared to currently available mass finishing systems is that the SF-HP is the world's first streamfinish machine for workpieces with a diameter and length of up to 650 mm and a weight of up to 200 kg.
The wide range of axis settings of the process head and spindle allows for virtually any workpiece pass through the process. This results in precise surface finishing in the shortest possible time, even for the smallest geometries. OTEC Streamfinish technology is a mechanical process without aggressive chemicals (a green process). The tribological surface properties are improved, meaning friction and abrasion are reduced.
Armen Papanian, Head of International Sales, explains details of the new SF-HPMr. Papanian, why did OTEC Precision Finish develop this new generation of the SF series?
"Our customers worldwide were asking for the proven SF technology to machine their larger and/or heavy workpieces. We could offer a solution for smaller workpieces up to 350 mm in diameter and 400 mm in length, and up to 60 kg in weight, but we didn't have a machine capable of handling larger dimensions. To offer the customer a system that covers most of their product range, we developed the SF-HP."
What types of workpieces can be machined with the new SF-HP?
"All types of workpieces up to 650 mm in diameter and height and up to 200 kg in weight can be machined in the SF-HP. Currently, our customers from the above-mentioned industries commission us with the finishing of their products. For example, we have received requests for improving the surface of blades to Ra=0.15-0.2µm, for defined edge rounding of gears with simultaneous
