Metav 2018 5-axis centre machines two tonnes within an 820-mm cube
The VC1650 5-axis machining centre from Germany-based machine tool builder Spinner is said to be able to machine complex components weighing up to two tonnes within an 820-mm cube.
Whitehouse Machine Tools markets this 5-axis machining centre from Spinner in the UK and Ireland and says it's rigidity and accuracy are assured by deploying a +1°/-110° B-axis spindle to provide the fifth CNC axis, thereby avoiding having to swivel the rotary table. A fixed table to the right of it allows for workpieces up to 1,650 mm to be supported horizontally for 3-axis metal cutting, extending the machine’s versatility. The spindle head centreline is offset by 200 mm to the left of its centre of rotation to allow features closer to the table to be machined, the company notes.
The patent-pending method protecting the table’s Y-axis guide way from swarf and coolant ingress with a single wiper system eliminates the need for a telescopic cover. The depth of the machine is thus shorter, with a 30% reduction in footprint. As the table moves to the extremes in the X-axis, automated loading and unloading from the sides is simplified. VC1650 has a FEM-optimisation cast structure to ensure rigidity and vibration damping for high-cutting performance and good surface finish on machined parts.
Features and options available are a 464 Nm high-torque spindle or a 18,000 rpm high-speed spindle, a 96-pocket magazine for SK50 / HSK100 tools or 138 pockets for SK40 / HSK63, a 70-bar high-pressure coolant instead of 22 bars, linear scales in X, Y and Z, and either a Siemens 840D sl control with Spinner’s 24-inch Touchpanel 4.0 interface or a Heidenhain TNC640 with a 19-inch screen.
The company will be exhibiting at Metav 2018 and will be in Hall 17, Booth B17.
