Vertical Spindle Machining Center VMC-1160L

The VMC-1160L is a vertical spindle machining centre built for medium-to-large parts where long overhang and continuous cuts demand damping as much as speed. The column's herringbone support span is optimised and paired with high-speed silent ball screws, which together suppress end-vibration when the spindle runs out over long X-axis parts. HT300 castings go through double aging so the frame stays dimensionally stable under high-temperature continuous operation. The BT40 11 kW spindle reaches 8,000 rpm through a timing belt; X/Y/Z travel is 1,100/600/600 mm over a 1,200 x 600 mm 800 kg table, with 36/36/30 m/min rapid traverse and a 24-tool disc magazine in 2.5-second exchanges. Cutting feed covers 1-10,000 mm/min, air supply is 6-6.5 kg/cm2 and required power is 25 kVA. Positioning holds at 0.01 mm and repeat at +/-0.003 mm. The result is a machine that does multi-process integrated machining on long shaft-like brackets and large cavity housings without moving the part between fixtures, weighing 7,600 kg to keep the long X travel rigid.

Because the VMC-1160L serves military-grade and automotive housings, buyers typically require OEM/ODM-style cooperation: their own datums, their own process routing and often their own controller specification. Our independent R&D team can map those requirements onto the optimised herringbone span - adjusting column width, screw pitch and spindle package - so the delivered machine is certified to their drawing rather than a generic catalogue unit, and the after-sales team (over 10 years in CNC) supports commissioning and first-article validation on site. The long X travel is verified on our Renishaw laser interferometer before shipment, so customers receive a machine whose linear pitch compensation is already tuned to their longest workpiece rather than being a generic factory test.

The suppressed end-vibration and double-aged castings hold tight tolerances on small-to-medium defence parts - brackets, housings and mounting plates - where datum drift across a long X travel is unacceptable.

With 1,100 mm X travel and 600 mm Y, the machine mills transmission covers, pump housings and long brackets in one set-up, reducing process turnover between milling, drilling and tapping stations.

The silent ball screws and herringbone column manage deflection on slender cantilever workpieces, supporting multi-process integrated machining that previously needed two machines.
