Multi-spindle auto for parts up to 40 mm diameter
1 min read
German multi-spindle automatic lathe manufacturer, INDEX, has introduced a six-spindle CNC machine with 40 mm bar capacity. The multi sits between the 32 mm and 52 mm capacity models in the MultiLine range, and is available from Geo Kingsbury.
The 6-spindle MS40C lathe can be customised with up to 12 CNC cross-slides, optional Y-axes and further equipment to enable high productivity one hit machining of up to 40 mm bar stock, or chucked parts up to about 70 mm in diameter.
Simultaneous back-working is achieved using one or two scara robot arms carrying synchronous, 13.5 kW / 10,000 rpm pick-up spindles that present parted-off components to six separate tools, two of which can be driven.
The core of the machine is the compact spindle drum with six fluid-cooled motor spindles rated at 24 kW / 7,000 rpm. C-axis positioning is available at all stations. The machine features V-shaped tool carriers that allow two CNC slides to work simultaneously at one spindle. Each of the 12 slides can perform internal or external turning, boring, or driven tool work.
Manufacturers and subcontractors are therefore not restricted to running one type of tool in any particular position, as there is no set order. Only the toolholder determines the type of machining. Off-centre drilling, thread cutting, inclined drilling, cross drilling, contour milling, gear hobbing, elliptical deburring and multi-edge turning are just a few of the many possibilities.
Control is by the INDEX C200-4D, a derivative of the Siemens 840D which is easy to program on the shop floor and automatically performs collision checking.
