Featuring a working volume of 815 x 510 x 510 mm in a small 2.5 x 1.8 m footprint, the new VC850-5A is the latest prismatic metal-cutting machine to be launched by German manufacturer Spinner.
The five-axis, vertical-spindle machining centre, which is configured with a +110/-5° swivelling trunnion carrying the rotary table, is available in the UK and Ireland through sole sales and service agent, Whitehouse Machine Tools.
Managing director Tim Whitehouse says: “This is a top-end machine with robust rotary axes, which are normally the weak point in five-axis machining. They are driven by a new planetary gear train and fitted with absolute rotary scales instead of incremental encoder feedback.
“We’re also impressed by the additional clamping plate beside the table that allows Op20 – as well as Op10 – to be programmed in a single cycle for one-hit machining,” he adds. “The option of a rotary hydraulic supply for automatic workpiece clamping is a further benefit, as it introduces the possibility of automation for long periods of unattended production.”
The 5-tonne machine has an FEM-optimised, cast construction that provides a high level of rigidity and vibration damping for elevated cutting performance and high standards of surface finish on machined components up to 200 kg. Further advantages are that tool life is extended and machining accuracy is enhanced, reports the company.
Part of the reason for the machine’s compactness is the patented method for protecting the saddle’s Y-axis guideway from swarf and coolant ingress using a single wiper system, eliminating the need for a telescopic cover.
