Ultra fast vertical machining centre

The YCM NSV102A vertical machining centre features a powerful 22 kW Isolated Direct Drive (IDD) spindle design that runs through ceramic angular contact bearings to provide superb axial and radial cutting rigidity at up to 12,000 rpm. Combined with roller-type linear guideways and a heavy-duty frame, the NSV102A is ideal for work that requires high chip removal rates. Oversized linear bearings on all guideways to offer an optimal balance between machining performance, rigidity and accuracy. Feedrates are 48 m/min in all three axes and axial acceleration up to 1 g (10 m/s2). Larger than standard spans are used on the NSK roller-type guideways to ensure stability, with the Y-axis bearings set 850 mm apart and the X-axis using a six bearing truck to increase the workpiece load on the table to 1,000 kg. Axis travels are 600 mm in Z and Y, while the X axis is 1020 mm. The worktable is 1,120 by 650 mm and can accommodate very heavy parts. The NSV102A is equipped dual screw-type chip augers each side of the Y axis that feed chips into a slatted-type swarf conveyor. The IDD 22 kW spindle design provides low spindle vibration and optimal heat isolation, resulting in an exceptional surface finish while maximising both spindle and cutting tool life under hard milling conditions.
