Key Features & Benefits:

Heavy-Duty Cast Iron Structure – The one-piece bed and column are made of high-quality Meehanite cast iron, stress-relieved to ensure long-term stability and vibration dampening. This allows for aggressive cutting without compromising surface finish.
4-Axis Capability – Equipped with a CNC rotary table (optional) or direct indexing, the machine enables complex multi-face machining in a single setup, reducing handling errors and increasing throughput.
BT40 Spindle with 12kW Power – The belt-driven spindle delivers ample torque for roughing and finishing operations on steel, stainless steel, aluminum, and other metals. The high-speed option (up to 12,000 rpm) is ideal for non-ferrous materials.
Generous Work Envelope – With 3000 mm X-axis and 1500 mm Y-axis travel, large parts such as diesel engine blocks, railway components, and press molds fit easily. The Z-axis clearance of 800 mm accommodates tall workpieces.
Precision Linear Guideways – All axes use heavy-duty roller linear guides with preloaded ball screws. The combination ensures high rigidity and smooth motion, achieving positioning accuracy within ±0.005 mm/300 mm.
Automatic Lubrication System – Centralized lubrication delivers oil to all critical sliding surfaces and ball screws automatically, extending machine life and reducing maintenance workload.
User-Friendly CNC Control – Choose from Siemens or Fanuc controllers, both offering intuitive interfaces, 3D simulation, and tool management. The control supports complex cycles and is compatible with CAD/CAM software.
Safety & Reliability – Full enclosure splash guard, interlock doors, and emergency stop buttons comply with international safety standards. Overload protection on all axes prevents damage.

Frequently Asked Questions (FAQ)

Q: What is the maximum workpiece weight the machine can handle?
A: The standard worktable is rated for up to 5,000 kg. If you need to machine heavier parts, please contact us for design evaluation – reinforcement options are available.
Q: Can I use this gantry mill for both roughing and finishing?
A: Yes. The 12 kW BT40 spindle provides high torque at low speeds for heavy roughing, while the high-speed range (up to 8,000 rpm) is suitable for fine finishing. With optional higher speed spindle, even better surface quality can be achieved on aluminum.
Q: What control system do you recommend for 4-axis work?
A: We strongly recommend Siemens 828D or Fanuc Oi-MF with option for rotary axis. Both support 4-axis interpolation and are widely used in mold and metalworking shops. We can pre-configure the control based on your part types.
Q: How long is the delivery time?
A: Standard machine delivery is 30–45 days after order confirmation. Customized configurations may require 60–75 days. We will provide a detailed schedule upon order.
Q: Do you offer training and installation support?
A: Yes, we provide free online training for basic operation and programming. For on-site installation and advanced training, our engineers can travel to your facility (travel costs negotiated).
Q: What is the spindle taper? Can I use standard BT40 tool holders?
A: The standard spindle is BT40 with pull stud retention. Any industry-standard BT40 tool holder (DIN 69871 or MAS BT) can be used. Optional SK40 or HSK-A63 are available upon request.
Q: Does the machine come with a chip conveyor?
A: A chip conveyor is an optional accessory. The standard equipment includes a coolant system with a removable chip tray. We can add a hinge belt or scraper conveyor to meet your production needs.
Q: How do you ensure the quality before shipment?
A: Each machine undergoes a 48-hour continuous run test, including spindle thermal growth check, axis positioning accuracy measurement, and real cutting test on a sample part. A final inspection report is issued before packaging.
