Features

Stable Machining

Resin-sand cast components with internal rib reinforcement are stress-relieved to maintain long-term geometric accuracy.

Rigid Cutting

Inverted "V" column layout provides superior bending and torsional rigidity for precise heavy cutting.

Smooth Motion

Precision linear guides on X/Y axes and hardened sliding guides on Z ensure smooth movement and consistent cutting force retention.

Precise Cutting

BT40 belt-driven spindle (11 kW, 15 kW peak, 8,000 RPM) delivers balanced roughing and finishing for both ferrous and non-ferrous metals.

Efficient Tool Change

24-station disc-type ATC completes tool changes in under 3 seconds and accommodates heavy, large-diameter tools for uninterrupted machining cycles.

Quality Assurance

Material and Casting Control

All castings undergo stress relief and rigorous inspection, with iron composition verified using Bruker spectrometer analysis to ensure material consistency and integrity.

Comprehensive Validation

Each machine is subjected to laser calibration (±0.008 mm positioning accuracy), a 24-hour load test, and automatic tool changer (ATC) cycle verification to guarantee reliable performance.

Complete Documentation

A full inspection report, including accuracy data, test logs, and compliance checklist, is provided prior to shipment to ensure traceability and quality assurance.

Packaging & Delivery

Export-Standard Packaging

Fumigated wooden crate reinforced with internal bracing, protected with VCI anti-corrosion wrap and desiccant packs to prevent moisture and corrosion during transit.

Monitored Transport

Tilt and shock indicators installed; machine secured for ISO container loading to ensure safe handling throughout shipping.

Transparent Delivery Process

Standard lead time: 30–45 days. Foundation drawings, electrical and air specifications, and packing list provided 7 days prior to shipment for smooth handover and installation.

After-Sales Support

Dedicated Technical Support

Direct access to application engineers via email and WhatsApp, with guaranteed initial response within 24 business hours to resolve technical inquiries efficiently.

Remote Commissioning Assistance

Secure remote support provided for system startup, parameter verification, and basic program validation, ensuring smooth initial operation.

Global Service Network

On-site installation, calibration, and training available through certified partners across Europe, North America, and Southeast Asia (services provided at buyer's expense), ensuring worldwide support coverage.

fAQ

Why does the Z-axis use sliding guideways instead of linear rails?
Sliding guideways provide higher rigidity and better vibration damping under heavy axial loads-critical for deep cavity milling and rigid tapping.

What's the maximum material hardness this machine can handle?
Optimized for materials up to HRC 45. Continuous machining of hardened steel (>HRC 50) is not recommended.

Is through-spindle coolant (CTS) available?
Yes-as a factory-installed option with high-pressure pump (up to 30 bar).

How is thermal expansion compensated?
Ball screws feature double-nut pre-tensioning and thermal compensation algorithms in the Fanuc control.

Can I upgrade to a hard rail version?
Yes-linear guideways on X/Y are standard, but a full hard rail configuration is available upon request.
