Our Core CNC Machining Equipment for Heavy-Duty Parts
We invest in top-tier machinery to handle large, heavy metal workpieces with exceptional precision—each device is regularly calibrated (quarterly) to maintain stability:
30140 CNC Machining Center
Key Specifications : X-axis travel 14000mm, Y-axis 3000mm, Z-axis 1500mm; Spindle speed 6000rpm (15kW spindle power);
Advantages :
- High-rigidity cast iron bed reduces vibration during heavy cutting (ideal for 45# steel, 304 stainless steel thick plates)
- 16-tool magazine + automatic tool length compensation, cutting efficiency improved by 40% vs. traditional machines
- Coolant system with chip conveyor prevents workpiece overheating during long machining cycles
3060 CNC Machining Center
Key Specifications :
-X-axis travel 6000mm, Y-axis 3000mm, Z-axis 1500mm; High-torque spindle (22kW, 3000rpm for hard metal); Automatic tool changer (24 tools, tool change time <2 seconds); Worktable load capacity 3000kg
Advantages :
-Specialized for long, narrow parts (e.g., 3000mm industrial guide rails) with consistent parallelism (≤0.02mm/m)
-Dust-proof and waterproof design, suitable for aluminum alloy (6061) and copper machining
Tempering Furnace
- Function :
- Eliminates internal stress of large workpieces (e.g., welded frames) to prevent post-machining deformation
- Enhances material hardness (up to HRC 50 for 45# steel) and fatigue resistance
- Quality Assurance : Each tempering cycle is recorded with temperature curves, provided to clients as quality proof
Welding & Assembly Workstations
- Welding Capabilities :
- MIG/TIG welding (welding thickness 3-50mm); Submerged arc welding for thick plates (50-150mm)
- Weld inspection: 100% visual inspection + ultrasonic testing (UT) for critical parts, meeting AWS D1.1 Class A
- Assembly Service :
- Integrated machining + welding + assembly for complex systems (e.g., custom industrial press frames)
- Parts cleaning (degreasing, rust removal) and surface treatment (painting, galvanizing) available

Custom Large-Scale CNC Machining Process
We simplify your customization journey with a transparent, efficient workflow—each step is tracked via a dedicated project manager:
- Demand Consultation (1-2 days)
- Our engineers review your CAD/STEP files, discuss material options (carbon steel, stainless steel, aluminum, copper), and confirm precision requirements (tolerance, surface roughness)
- Provide DFM (Design for Manufacturability) suggestions to reduce costs (e.g., optimizing part structure to avoid complex machining)
- Quotation & Contract (24 hours)
- Detailed quote including material cost, machining fee, heat treatment, and shipping (FOB/CIF terms available)
- Sign NDA if needed to protect your design confidentiality
- Process Design (3-5 days)
- Create machining drawings and process flowcharts (shared with you for approval)
- Prepare custom jigs/fixtures if required
- Sample Trial (7-10 days)
- Produce 1-2 prototypes; conduct dimensional inspection and material testing (hardness, tensile strength)
- Ship sample to you for physical inspection; adjust processes based on feedback (free re-sample if needed)
- Bulk Production (2-4 weeks)
- Use 30140/3060 machining centers for stable production; conduct in-process inspection (5% sampling rate)
- Heat treatment, welding, and assembly (if required)
- Final Quality Inspection (1-2 days)
- 100% dimensional inspection with CMM; 3D scanning for complex parts
- Material certification (MTC) and quality report provided
- Packaging & Delivery
- Custom packaging (wooden cases, anti-rust film) to protect large parts during shipping
- Support sea/air shipping (cooperate with DHL, Maersk; door-to-door service available)
- After-Sales Service
- 1-year warranty for machining defects (free repair/replacement if issues occur)
- Technical support via email/Zoom (response within 8 hours)

FAQs
Q1: What’s the maximum size of parts you can machine?
A: Our 30140 machining center handles workpieces up to 14000×3000×1500mm. For larger parts (e.g., 9000mm-long frames), we offer split machining + welding assembly—we’ve successfully delivered 12000×2000×1000mm parts for industrial presses.
Q2: How long does a custom large CNC part take to produce?
A: Prototypes: 7-10 days (faster for simple parts: 5 days); Bulk production: 2-4 weeks (depends on complexity and quantity). For urgent orders, we can arrange overtime production (30% faster with a 15% premium).
Q3: Do you provide material sourcing? Can we use our own materials?
A: Yes to both! We source high-quality materials from trusted suppliers (with MTC certificates). If you have preferred materials, we can process them—just provide material specifications and delivery address (we handle customs clearance for imported materials).
Q4: What surface treatments do you offer for large parts?
A: We provide painting (epoxy, polyurethane), galvanizing (hot-dip, electro-galvanizing), chrome plating, anodizing (for aluminum), and passivation (for stainless steel). We can also meet custom requirements (e.g., FDA-approved coatings for food industry parts).
Q5: How do you ensure parts are not damaged during shipping?
A: Large parts are packaged in heavy-duty wooden cases (IPPC-certified for international shipping) with anti-rust film and foam padding. For extra-large parts (e.g., 3000mm frames), we use steel frames for reinforcement. We also purchase shipping insurance (100% compensation for damage).
