Dual-Bearing CNC Lathe Machine for Metal Processing

Product Overview

Designed as the pinnacle of sub-micron precision metalworking, the 4200 RPM Dual-Bearing Ultra-Precision CNC Lathe integrates double-row angular contact bearings with hydrostatic guideways to achieve ±0.001mm positioning accuracy—a level of precision validated by ISO 230-2 standards. Its 4200 RPM direct-drive spindle, powered by a 11kW high-torque motor, delivers ≤1.5μm radial runout even under full load, making it the ideal solution for machining aerospace turbine blades and medical implant components where dimensional consistency is critical. The BMT55 servo turret supports 8 tool stations with 0.2-second tool change time, enabling live milling, drilling, and tapping in a single setup—reducing cycle times by 30% compared to conventional multi-machine processes.

Product Features

Dual-Bearing Spindle System:

Preloaded angular contact bearings (C3 clearance) with spring-loaded preload adjustment maintain thermal stability within ±0.5°C, even during 12-hour continuous machining of Invar 36 and tungsten carbide.

Oil-air lubrication system delivers 0.05ml/min per bearing to reduce friction by 60%, extending bearing service life to 20,000+ hours—30% longer than grease-lubricated alternatives.

Hydrostatic Guideway Technology:

Constant-pressure oil film (5MPa) generated by progressive cavity pumps eliminates stick-slip motion, ensuring Ra ≤0.05μm surface finish on optical lens molds and semiconductor tooling.

Heidenhain LC 483 linear scales with 0.1μm resolution provide real-time position feedback, validated via VDI/DGQ 3441 standard for ultra-precision machining.

Advanced Control Architecture:

Siemens 840D sl controller with AI-driven collision avoidance analyzes 500+ data points/second to prevent tool collisions during 5-axis helical interpolation for complex aerospace components.

Offline simulation module (Siemens NX CAM) reduces setup time by 50% via virtual twin technology, allowing operators to validate toolpaths before production.

1.High-precision parts machining

The core components of pneumatic components (such as valve cores, pistons, sealing grooves, and air passages) have extremely high requirements for dimensional tolerances and surface roughness. CNC machine tools can achieve micron-level precision through programmed control, ensuring the airtightness and durability of the components.

Typical applications: high-precision boring of cylinder inner walls, positioning machining of complex hole systems in valve bodies, and precision grinding of sealing surfaces.

2.Complex Geometric Shape Machining

Pneumatic components often involve irregular curved surfaces, multi-angle channels, or thin-walled structures (such as valve body flow channels and pneumatic connectors). CNC machine tools can complete the machining of complex geometric shapes in a single setup, eliminating human error.

Typical applications: milling of three-dimensional curved air passages, tapping of multi-angle threaded holes, and high-stability machining of thin-walled valve bodies.

3.Mass production and consistency assurance

CNC machine tools can quickly switch between processing tasks and achieve mass production through programmed control, ensuring product consistency and reducing scrap rates.

Typical applications: Mass turning of standardised cylinder end caps, automated processing assembly lines for pneumatic solenoid valve bodies
