4-Axis CNC Machining for Complex Geometries
Our 4-axis CNC machining centers combine rotary axis capabilities with traditional 3-axis milling, enabling us to machine complex parts with undercuts, angled features, and continuous contours in a single setup. This multi-axis approach eliminates multiple setups, reduces cumulative positioning errors, and ensures superior geometric accuracy. We operate Doosan, DMG MORI, and Mazak machining centers equipped with high-speed spindles (12,000-24,000 RPM) and advanced tool management systems.
The fourth rotary axis allows continuous indexing and simultaneous 4-axis interpolation, critical for aerospace components, medical device housings, and precision instrumentation parts. Our CAM programming team utilizes Mastercam and Siemens NX to generate optimized toolpaths that minimize cycle time while maintaining surface finish requirements (Ra 0.8-3.2μm). Fixture design is customized for each project to ensure rigid workholding and vibration-free machining.
Large Format Gantry CNC Processing
For oversized structural components and equipment frames, our 12-meter gantry CNC machining center provides the capacity to machine large workpieces that exceed standard machine tool envelopes. This bridge-type machine features a moving gantry structure with exceptional rigidity, capable of maintaining ±0.05mm positional accuracy across the entire 12m x 4m x 2m work envelope. Applications include wind turbine main frames, semiconductor equipment chambers, and industrial machinery bases.
The gantry CNC is particularly valuable for post-weld machining of fabricated structures where welding distortion must be corrected through precision milling. We employ vibration stress relief and thermal stabilization before final machining to prevent dimensional instability. Heavy-duty cutting tools with indexable inserts handle interrupted cuts and varying material sections common in welded assemblies. Zeiss CMM verification ensures all critical dimensions meet drawing specifications.
High-Precision CNC Turning Services
Our CNC turning department operates multi-axis lathes with live tooling, sub-spindles, and Y-axis milling capabilities. This allows complete machining of complex turned parts including shafts, flanges, and valve bodies without secondary operations. Maximum turning diameter reaches 800mm with 2000mm between centers, accommodating both small precision components and large industrial parts. Turning accuracy of ±0.01mm is maintained through thermal compensation, high-resolution encoders, and rigid machine construction.
Live tooling stations enable milling, drilling, and tapping operations on turned parts, eliminating transfer to separate milling machines. Sub-spindle capability allows backside machining and part-off operations that produce finished components ready for assembly. We machine a wide range of materials including aluminum alloys (6061, 7075, 2024), stainless steels (304, 316, 17-4PH), carbon steels, and engineering plastics. Surface finishes down to Ra 0.4μm are achievable through precision turning and grinding operations.
Aluminum CNC Machining Expertise
Aluminum machining requires specialized knowledge of material properties, cutting parameters, and thermal management. Our aluminum machining services cover aerospace-grade 7075-T6, marine-grade 5083, and general-purpose 6061-T6 alloys. High-speed machining strategies with optimized chip evacuation prevent built-up edge formation and ensure excellent surface finish. Flood coolant systems and through-spindle coolant delivery maintain consistent cutting temperatures and extend tool life.
For thin-walled aluminum components prone to deflection, we employ strategic fixturing, climb milling techniques, and adaptive toolpath strategies that minimize cutting forces. Anodizing, chromate conversion coating, and powder coating services are available for corrosion protection and aesthetic requirements. All aluminum parts undergo deburring and edge break operations to remove sharp edges and burrs. Dimensional inspection includes CMM measurement, surface roughness testing, and visual quality checks.
