Product Description

Product Focus

Large-Mold Processing Advantages

Unlike smaller mold-focused CNC machining tools, the VC-610 solves large-mold pain points: frequent repositioning, clamping errors, and stable cutting for big workpieces—gaps general vertical CNC machines can’t fill.

◈
Large Worktable for One-Time Clamping: Its 1100×650 mm worktable (800 kg load) fits large molds (automotive door panels, appliance shells). Unlike smaller 950×600 mm tables that split molds into 2–3 setups, it eliminates repositioning errors, ensuring consistent accuracy across the mold.
◈
Extended X-Axis for Full-Mold Machining: X/Y/Z travel of 1050/610/530 mm (X-axis 200 mm longer than smaller models) covers full large-mold lengths, avoiding "segmented seams" common in milling centers with shorter travels—critical for 1m-long molds (e.g., refrigerator doors).
◈
Oil-Air Spindle for Long Runs: Large molds need 10+ hours of continuous machining. The oil-air spindle reduces heat, preventing thermal warping (a risk with basic vertical milling machines’ grease-lubricated spindles). Its 12000–20000 rpm speed and 11–40 kW motor adapt to roughing mold bases and finishing surfaces.
◈
BBT-40 Tool Holder for Precision: Dual contact (taper + face) ensures tool stability during high-speed cutting of large mold details (e.g., bumper ribs), outperforming standard BT-40 holders in CNC turning centers that cause runout for big workpieces.

Core Value & Applications

✓
Time Savings: One-time clamping cuts setup time by 40% for big-tool projects.
✓
Accuracy: No repositioning meets automotive/appliance mold OEM tolerances.
✓
Stability: Oil-air spindle and rigidity reduce rework for high-value large molds.

Typical uses: Automotive bumper/fender molds, large appliance drum/liner molds, and industrial pallet molds—leveraging table size, X-axis travel, and motor power for efficient processing.

Frequently Asked Questions

What makes the VC-610 suitable for large automotive molds?
The VC-610 features an extended X-axis travel of 1050mm and a large 1100x650mm worktable, allowing for one-time clamping of large components like bumper ribs and door panels, eliminating repositioning errors.
What are the benefits of the Oil-Air Spindle?
The oil-air lubrication system significantly reduces heat generation during long-duration machining (10+ hours), preventing thermal warping and ensuring surface finish consistency compared to standard grease spindles.
How much weight can the VC-610 worktable support?
The reinforced worktable is designed to handle a maximum loading capacity of 800 kg, making it ideal for heavy industrial and appliance molds.
What is the advantage of the BBT-40 tool holder over standard BT-40?
The BBT-40 utilizes dual contact (both taper and face), providing superior stability and rigidity during high-speed cutting, which reduces tool runout and improves accuracy for intricate mold details.
Can the spindle speed and motor power be customized?
Yes, the VC-610 offers various spindle speed options ranging from 12,000 to 20,000 rpm and motor power configurations from 11kW up to 40kW to suit different roughing and finishing requirements.
How does this machine improve production efficiency?
By allowing one-time clamping for large workpieces, it reduces setup time by approximately 40% and eliminates the risk of "segmented seams" found in smaller machines with shorter travels.
