Mold CNC Mill Tongtai VC-608: Oil-Air Spindle

Unlike auto-focused CNC machining tools, the VC-608 targets mold manufacturing challenges: precise contouring, spindle heat control for long runs, and tool stability for complex cavities—needs general-purpose vertical CNC machines often don’t address.

● Oil-Air Lubrication Spindle: Mold processing often requires 8–12 hours of continuous spindle operation. The VC-608’s oil-air lubrication reduces friction heat, avoiding thermal deformation that skews mold dimensions (a issue with basic milling centers’ grease-lubricated spindles). With spindle speeds up to 20,000 rpm (12,000 rpm standard) and matching motor power, it handles mold surface finishing and base roughing.

● BBT-40 Dual Contact Tool Holder: Mold cavities need tool runout control for smooth surfaces. The VC-608’s BBT-40 system (taper + face contact) locks tools tightly, ensuring consistent cutting depth for mold ribs/undercuts—outperforming standard BT-40 holders in CNC turning centers (only taper contact).

● Dynamic Rigidity for Mold Shapes: Mold 3D contouring requires frequent direction changes. The VC-608’s structure resists torsional deformation, maintaining path accuracy. Its 950×600 mm worktable (800 kg max load) fits medium molds, while X/Y/Z travels (850/610/530 mm) accommodate deep cavities without repositioning, cutting setup time.

● High-Precision Control: Equipped with high-speed, high-precision control, it supports micro-step feeding for fine mold features (draft angles, textures). Its 24/24/24 m/min rapid traverse balances speed and stability, avoiding overshoot that risks damaging mold surfaces (a flaw in faster but less controlled vertical milling machines).

● Long Spindle Life: Oil-air lubrication reduces wear, lowering maintenance costs for high-utilization mold shops.

● Mold Precision: BBT-40 dual contact and dynamic rigidity meet strict injection mold/stamping die accuracy standards.

● Tooling Flexibility: Optional 30-tool magazine and multi-power spindle motor (11–40 kW) adapt to mold materials (aluminum to hardened steel), no need for specialized machines.

● Injection molds: Machining plastic part molds (e.g., electronic housings) with smooth surfaces via high spindle speed.

● Stamping dies: Roughing/finishing die cavities for metal parts, using rigidity to avoid deformation.

● Precision tooling: Making mold inserts/core pins, relying on micro-step control for fine features.
