Extra-Large Mold CNC Mill Tongtai VC-711: High-Load Oil-Air Spindle

Unlike large-but-limited CNC machining tools (e.g., for medium-large molds), the VC-711 targets ultra-big mold pain points: heavy workpiece clamping, 3D full-contour machining, and long-run stability—needs general vertical CNC machines or smaller mold mills can’t address.

● Extra-Large High-Load Worktable: Its 1200×710 mm worktable (1000 kg max load) fits super-large molds like automotive chassis molds or industrial equipment shell molds (e.g., 1.2m-wide excavator cab molds). Unlike smaller 1100×650 mm tables that struggle with heavy oversized workpieces, this design ensures stable clamping without table deformation—critical for maintaining accuracy of heavy mold bases.

● Triple-Axis Extended Travel: X/Y/Z travel of 1100/710/710 mm (Y/Z axes 100 mm longer than VC-610) covers 3D full contours of deep, wide molds (e.g., tall refrigerator side panel molds). It avoids "layered machining" gaps common in milling centers with shorter Z-axis travel, ensuring smooth integration of mold cavities and ribs.

● Oil-Air Spindle for Heavy Mold Long Runs: Super-large molds require 12+ hours of continuous machining. The oil-air spindle reduces friction heat, keeping rotation stable even when cutting thick mold steel—preventing thermal expansion that warps large mold dimensions (a flaw in basic vertical milling machines). Its 12000–20000 rpm speed and 40 kW max motor power handle roughing heavy mold bases and finishing precision surfaces.

● BBT-40 Tool Holder for Big Mold Details: Ultra-large molds need uniform cutting force for edge details (e.g., automotive frame mold joints). The BBT-40 dual contact system (taper + face) eliminates tool runout, ensuring consistent cutting depth—outperforming standard BT-40 holders in CNC turning centers that fail to stabilize tools for super-large workpiece machining.

● Heavy Mold Compatibility: 1000 kg load handles overweight molds, no need for split clamping.

● 3D Full-Contour Machining: Triple-axis travel covers deep/wide molds, reducing rework.

● Long-Run Stability: Oil-air spindle and rigidity ensure accuracy for high-value super-large molds.

Typical uses: Automotive chassis/frame molds, industrial equipment shell molds, and large-scale injection molds—relying on table size, load capacity, and travel to simplify ultra-big tooling processing.
