Celebrating 50 Years of Rotary Transfer

September 16, 2016 / , Senior Editor Production Machining


For more than 50 years, Winema Maschinenbau GmbH (supported in the United States by ACI Machine Tool Sales LLC of Lawrenceburg, Kentucky) has been manufacturing rotary transfer machines. All of the machines’ mechanical components are made in the company’s plant in Grosselfingen, Germany, or by qualified partner businesses. Visitors to Booth N-7098 can check out Winema’s latest offerings in rotary transfer technology.

New to the market is the company’s RV 30 Flexmaster, designed for medium and large workpieces (diameters of 15 to 50 mm and lengths to 200 mm). Raw material is fed either from the bar, via the Winema loading cartridge, or as a blank placed directly into one of 10 clamping stations. Workpieces can be machined from three sides simultaneously at each station and can be turned or repositioned at defined stations. The station with the longest machining time determines the cycle time. All machining feeds of the vibration-reducing quill units are CNC-controlled and are equipped with hydraulic drives and direct measuring systems. The machine offers the possibility to carry out radial drilling and milling operations at as many as four stations (thread milling or contour milling). A flange-mounted angle head allows machining such as the milling of wrench sizes, polygon milling, slotting, front-side partial-circle drilling, contour milling and so on.

Also on display in the booth is Winema’s RV 10 Flexmaster, designed for workpieces with diameters between 2 and 13 mm and lengths ranging to 80 mm. The indexing table on this machine also has 10 clamping stations with centric clamping jaws. The workpiece can be processed with a maximum of 18 axial and four radial machining units. Indexing time of the table is less than 0.3 seconds.
