Vertical CNC Milling Machine VMC-1380LH

The VMC-1380LH is a vertical cnc milling machine engineered for large-sized heavy-cutting work. Its core structure is a reinforced, widened four-linear-guide base paired with a herringbone column and a six-slider worktable; the column and spindle box use a hard-rail structure to carry heavy-cut loads. A 15 kW spindle motor delivers the power needed for heavy removal on large parts, HT300 castings go through double aging, and high-speed silent ball screws with precision grinding keep the datum stable under load. X/Y/Z travel is 1,300/800/700 mm over a 1,500 x 800 mm table rated at 900 kg; the spindle taper is BT50, speed 8,000 rpm through a timing belt, rapid traverse 30/30/24 m/min, and the 24-tool disc magazine exchanges tools in 3.75 seconds. Cutting feed covers 1-10,000 mm/min, air supply is 6-6.5 kg/cm2 and required power is 25 kVA. A deadweight balance system supports the heavier spindle package. At 9,500 kg the machine targets large automotive casings, military components and heavy mould blocks where both reach and stock removal matter.

Large heavy-cutting buyers typically send their own casting or steel-part drawings and need the machine engineered around the part, not the reverse. The VMC-1380LH's value is in OEM/ODM cooperation plus drawing-based manufacturing: our R&D team takes the customer's cavity and load drawings, then tunes the four-guide widened base, BT50 spindle package and deadweight balance to the actual large-part envelope. Because we control casting supply, machining and assembly in-house, structural changes and material mix are quoted against signed customer drawings, and first-article validation is part of the delivery.

The 1,300 x 800 mm table and BT50 15 kW spindle rough-mill large gearbox housings and oil-pump covers in one set-up, where a smaller taper would flex under chip load.

The reinforced four-guide base and hard-rail column hold heavy cuts on thick defence housings and brackets, with the deadweight balance stabilising the heavy spindle over long Z moves.

For large injection and die-cast mould blocks, the 700 mm Z travel and 900 kg table load support deep-cavity heavy milling without a second machine.
