Product Description

Product Focus

Tooling Industry-Specific Solutions

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. With spindle speeds up to 20,000 rpm (12,000 rpm standard), it handles mold surface finishing and base roughing efficiently.
🔧
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.
🏗️
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.
🎯
High-Precision Control: Equipped with high-speed, high-precision control, it supports micro-step feeding for fine mold features like draft angles and textures. Its 24/24/24 m/min rapid traverse balances speed and stability, avoiding overshoot risks.

Core Value for Tooling Manufacturers

💎

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 from aluminum to hardened steel.

Typical Tooling Applications

🔹 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.

Frequently Asked Questions

How does the VC-608 handle long machining cycles?
The VC-608 utilizes an oil-air lubrication spindle system specifically designed for continuous operation (8–12 hours), reducing friction and thermal deformation to maintain mold accuracy.
What makes the BBT-40 system better for mold making?
The BBT-40 dual contact system provides both taper and face contact. This ensures higher rigidity and better tool runout control, which is essential for machining smooth mold ribs and deep cavities.
Can this machine process hardened steel molds?
Yes. With optional high-power spindle motors (up to 40 kW) and a rigid structure designed for dynamic stability, the VC-608 is capable of machining materials ranging from aluminum to hardened steel.
What is the maximum weight capacity of the worktable?
The worktable measures 950x600 mm and can support a maximum loading capacity of 800 kg, making it suitable for most medium-sized mold bases.
What are the available spindle speed options?
The standard spindle speed is 12,000 rpm, with optional configurations available for 10,000, 15,000, or high-speed 20,000 rpm to suit different finishing requirements.
Is the machine suitable for fine detail work?
Yes, the VC-608 features high-precision control with micro-step feeding, which is critical for achieving the necessary draft angles and fine textures in precision mold manufacturing.
