Compact five-axis machining centreAnyone needing to machine complex components weighing up to 2,000kg within an 820mm cube may wish to consider the
new VC1650 five-axis machining centre from Spinner, which is represented in the UK and Ireland by Kenilworth-based Whitehouse Machine Tools Ltd (www.wmtcnc.com).

Rigidity and accuracy are ensured by using a +1/-110deg B-axis spindle to provide the fifth CNC axis, thereby avoiding having to swivel the rotary table.

Furthermore, a fixed table to the right of the rotary table allows workpieces up to 1,650mm long to be supported horizontally for three-axis metal cutting, extending the machine’s versatility; and because the spindle head centre-line is offset by 200mm to the left of its centre of rotation, features close to the table can be machined.

Also featured is a method of protecting the table’s Y-axis guideway from swarf and coolant ingress by means of a single-wiper system that eliminates the need for a telescopic cover.

This allows the depth of the machine to be shorter, resulting in a 30% reduction in the overall footprint; and because the table moves to its extremes in the X axis, automated loading and unloading from the sides is simplified.

Customers can choose from a variety of alternative features and options, including: a 464Nm high-torque spindle or an 18,000rev/ min high-speed spindle; a 96-pocket magazine for SK50/HSK100 tools or 138 pockets for SK40/HSK63 tools; 70-bar high-pressure coolant (instead of 22-bar); linear scales in the X, Y and Z axes; and either a Siemens 840D sl control with Spinner’s Touchpanel 4.0 interface or a Heidenhain TNC640.

For chip disposal, Spinner provides four spiral augers that deliver chips to a conveyor at the front of the machine for convenient removal. This configuration also ensures that there is negligible heat transfer to the machine structure.

Be seen in all the right places!
