Dean Machine Tools (formerly “Doosan Machine Tools”) DVF5000 helps Germany’s Raussendorf achieve complex‑shape and multi‑functional machining.

　　Germany’s Raussendorf company presents the DVF5000, a 5-axis vertical machining center from Dean Machine Tools—formerly “Doosan Machine Tools”—that delivers both complex‑shape machining and multi‑functional capabilities!

　　“Among the 17 machine tools owned by our company, the DVF 5000 is the one we’re most satisfied with—its performance only improves with increased use,” said Robert Redman, Production Management Manager at Raussendorf Maschinen-und Gerätebau GmbH, a German firm that purchased a DVF 5000 model from Doosan Machine Tools (formerly “Doosan Machine Tool”) in 2019.

　　According to the company’s on-site report, the DVF 5000 has been praised for its technical advantages, including enhanced efficiency, deburring capabilities, flexible processing of a wide range of materials, and optimized service.

　　“Doosan equipment can clamp four components simultaneously and complete all machining operations within 12 minutes, reducing cycle time by 300% compared to the past.”

　　Challenge

　　Expand the scope of machining and manufacturing activities across multiple industries!

　　Raussendorf Maschinen- und Gerätebau GmbH, with a history spanning 150 years (hereinafter referred to as Raussendorf), is a contract manufacturer specializing in mechanical and equipment engineering, agricultural machinery, and related products.

　　Prioritizing “meeting customer needs,” the company is expanding its production activities across multiple industries to adapt to the evolving machining environment and ensure stable business operations. In particular, the company’s representative, Mr. Hannes Stefan Hannenheim, has anchored the core strategy on “strengthening manufacturing expertise centered on machining equipment” and has consistently invested in enhancing R&D capabilities in this area over the years.

　　Solution

　　1. Flexible production and broad material compatibility

　　Multi-variety, small-volume production • Few-variety, large-volume production

　　Raussendorf processes workpieces made from a wide range of materials, using the DVF 5000—from soft materials such as aluminum and plastics to brass, castings, steel, stainless steel, and Hardox steel.

　　Robert Redman also stated, “The high degree of composite functionality and versatile applications offered by Dean Machine Tools (formerly Doosan Machine Tools) are clearly advantageous.” He added, “From small to large batch sizes and across a wide range of workpiece materials, the DVF 5000 can handle it all—capabilities that have been validated both within our company and by our customers.”

　　2. Tool position, clamping options, and machine speed

　　For process‑centric operations, the efficiency experienced by customers can increase by as much as 300%.

　　“The DVF machine is a 5-axis vertical machining center equipped with a rotary‑axis turntable, delivering significant savings in both machining time and cycle time,” Robert Redman added. “When performing machining operations, our company utilizes a large rotary‑axis turntable. With a single clamping, it can simultaneously machine four workpieces, thereby not only reducing machining time but also boosting production capacity.”

　　Raussendorf uses Doosan equipment to machine brackets for inspection tools; the finished brackets are then employed in laser‑cutting systems manufactured by a renowned company. “Doosan machines deliver repeatability as tight as 2/1000 mm, a performance that exceeds our customers’ requirements.”

　　Robert Redman also stated, “The Doosan machine tool model ‘DVF 5000’ used by Raussendorf features a 40‑tool turret and, thanks to its ‘Tool Load Monitoring Software,’ offers conditions that help shorten cycle times. Its key advantage is the ability to smoothly machine components with complex geometries.”

　　3. Equipment for perfectly deburring four components

　　Four-sided machining, thread cutting, and the machining of four components can all be completed in just 12 minutes.

　　Robert Redman believes that the DVF series’ tool magazine achieves faster tool changes than any machine from Raussendorf. Even with large tools measuring 75 × 300 mm and weighing up to 8 kg, it can supply all the tools required for machining in just 1.5 seconds.

　　“In the past, it took 12 minutes to clamp a single workpiece and complete machining,” said the spokesperson. “But Doosan’s equipment can simultaneously clamp four components, allowing all operations to be finished within 12 minutes—shortening the cycle time by 300% compared with previous systems.”

　　In recent years, Raussendorf has expanded the machining capabilities of its DVF 5000, extending its applications beyond just the holder for alignment gauges to include indexing pins, prototype cams for the automotive industry, coupling bases, and more. The company added, “There’s no need to make any special preparations to the machining equipment, allowing for flexible production of diverse components, and the DVF system’s versatility will only continue to improve in the future.”
