Compact CNC Mill-Turn Machine 330mm High-Precision Machining

Product Overview

The BMT40 High-precision CNC Mill-Turn emerges as a compact yet highly capable solution tailored for machining complex parts across industries where precision is non-negotiable—including aerospace, electronics, and optical engineering. With a 7.5KW high-performance spindle and a versatile BMT40 turret, this machine seamlessly combines advanced live tooling to produce intricate geometries —a level of precision that eliminates the need for secondary finishing operations. Its gantry-style design provides exceptional structural rigidity, while direct-drive motors on all axes eliminate backlash and enhance dynamic response, ensuring smooth motion even during high-speed machining. Designed for both small-batch prototyping and high-precision production, the BMT40 redefines what’s possible in a compact CNC machine footprint.

Product Features

Multi-Tasking Capability

The BMT40’s versatility shines through its multi-tasking design, centered around the BMT40 turret that supports 12 or 15 tool stations—more than enough to accommodate a full range of turning tools, milling cutters, drills, and taps. What sets it apart is the inclusion of live milling spindles in the turret, enabling where the turret acts as a secondary spindle, rotating and feeding while the main spindle indexes. The high-speed spindle reaches 20,000 RPM, paired that ensures secure, precise tool clamping—critical for accommodating micro-tools as small as 0.3mm in diameter for fine feature machining. This capability allows the BMT40 to produce complex parts like micro-machined connectors and aspheric lens molds in a single setup, reducing lead times by up to 50%.

Thermal Stability

In high-precision machining, temperature fluctuations can ruin even the most carefully programmed toolpaths—and the BMT40 addresses this with advanced thermal management. The temperature-controlled spindle uses internal cooling channels and a dedicated thermal sensor to maintain consistent operating temperatures, while the coolant jacketed machine structure circulates temperature-stabilized coolant around critical components like the bed and ballscrews. Together, these features maintain thermal equilibrium within ±0.5°C—a level of stability that’s critical for machining optic lens molds where sub-micron surface finishes are required, and micro-mechanical components where tight tolerances directly affect functionality. Complementing this are ceramic linear guides that reduce friction-generated heat and resist wear, extending the machine’s service life while preserving precision over time.

Advanced Programming

Programming the BMT40 is made efficient by the Heidenhain TNC 640 controller, a industry leader in high-precision machining control. The controller offers 3D path optimization that smooths toolpaths to reduce vibration and improve surface finish, while its AI-driven collision avoidance system analyzes toolpaths in real time to prevent crashes—even when machining complex 5-axis contours. A standout feature is the virtual machining module, which allows operators to simulate entire machining programs offline using a digital twin of the machine. This not only identifies potential issues before cutting starts but also reduces setup time by 50% compared to traditional trial-and-error methods. The controller also supports CAD/CAM integration, enabling seamless import of 3D models for direct programming of complex geometries.

Automation Ready

Designed for modern manufacturing environments, the BMT40 is fully automation ready, allowing it to integrate seamlessly into smart factory ecosystems. It can be paired with collaborative robotics cells for automated loading and unloading, and pallet changers that reduce setup time between batches by swapping out workholding fixtures in seconds. For small-batch production, the machine supports unattended operation with features like automatic tool length measurement and broken tool detection. A built-in tool presetter ensures ±0.002mm tool length accuracy, eliminating manual measurement errors and minimizing downtime during tool changes. These automation features make the BMT40 ideal for industries like electronics, where quick changeovers between part numbers are essential.

1.High-precision component manufacturing

CNC machine tools use AI technology to optimise processing parameters, significantly improving the precision and consistency of robot core components.

2.Intelligent production processes

AI enables CNC machine tools to achieve a closed loop of ‘perception-learning-decision-control,’ optimising the entire robot manufacturing process:

Intelligent programming and code generation: AI assistants can automatically generate CNC code through voice or text commands, increasing programming efficiency by several times and supporting rapid response to personalised orders.

Adaptive processing and process optimisation: Based on AI large model fusion modelling technology, the CNC system can adjust processing parameters in real time.

Predictive maintenance and fault diagnosis: The AI fault diagnosis system has reached the level of an engineer with 1-2 years of experience, reducing downtime and ensuring the stable operation of robot production lines.

3.Driving the intelligent upgrade of robots

The combination of CNC machine tools and AI technology directly helps industrial robots achieve a higher level of intelligence.

Intelligent R&D support: Precision components processed by five-axis CNC machine tools (such as impellers and biomimetic structures) provide a highly flexible hardware foundation for embodied intelligent robots.

Data-driven flexible production: CNC systems open data interfaces to support seamless integration with robot production lines, enabling flexible manufacturing of multiple varieties in small batches.
