Our Advanced CNC Machining Processes
CNC Milling
Our high-speed CNC milling centers utilize multi-axis capabilities to create complex geometries with tight tolerances down to ±0.005mm. We excel in producing intricate parts including housings, brackets, and molds from various materials.
The CNC milling process involves rotating cutting tools that remove material from a fixed workpiece. Our 5-axis machines allow for simultaneous movement along multiple axes, enabling us to machine complex 3D shapes in a single setup.
- 3-axis, 4-axis, and full 5-axis simultaneous machining
- High-speed spindles up to 24,000 RPM for efficient material removal
- Automated tool changers for maximum efficiency and reduced setup time
- Advanced coolant systems to maintain tool life and surface quality
- Support for complex geometries including pockets, slots, and 3D contours
Our milling capabilities extend from simple 2.5D profiles to complex 5-axis simultaneous machining. We use specialized tooling strategies for different materials, optimizing cutting parameters to achieve optimal surface finishes and production efficiency.
High-precision CNC Milling Center in operation
CNC Turning & Lathe Operations
Precision CNC turning delivers superior cylindrical components with excellent concentricity and surface finishes as fine as Ra 0.4μm. Our multi-tasking turning centers combine turning, milling, and drilling in one setup.
In CNC turning, the workpiece rotates while a fixed cutting tool removes material to create cylindrical shapes. Our turning centers are equipped with live tooling capabilities, allowing us to perform milling and drilling operations without repositioning the workpiece.
- Live tooling for complex features and secondary operations
- Bar feeder capacity up to 65mm diameter for unattended production
- Sub-spindle capabilities for complete machining of both ends
- High-precision spindle bearings for exceptional concentricity
- Support for thread cutting, knurling, and grooving operations
We specialize in producing shafts, pins, sleeves, and other rotational components with tight tolerances. Our turning centers can handle diameters from 1mm to 300mm with lengths up to 1500mm.
