Wire EDM + Grinding + CNC Machining: Crafting High-Precision Parts
From complex mold cavity components to precision collets and gear blanks, perfect metal part forming relies on the synergy of Wire EDM, grinding, and CNC machining. These three processes work together to create a seamless design-to-finish workflow for high-precision, complex components. Dongguan Senfa Precision Machinery Co.,Ltd. — a professional precision machining enterprise — uses this integration to deliver custom solutions for global customers.
I. Multi-Process Integration: Wire EDM, Grinding & CNC for Precision Machined Parts
The machined parts in the pictures cover mold accessories, tooling fixtures, and precision mechanical components. All are made possible by combining Wire EDM, grinding, and CNC machining:
- Core mold parts: CNC roughs out mold inserts, cavity plates, and base blocks. Wire EDM cuts complex contours with high precision. Grinding machines add the final precision grind for flat and outer surfaces. This ensures mold clamping accuracy hits the micron level. Explore our custom mold components machining to see how we deliver flawless mold parts for automotive and electronics industries.
- Tooling fixtures: CNC machines shape ER collets and positioning templates, cutting basic holes and outer forms. Wire EDM carves the elastic grooves in collets. Cylindrical grinders finish the outer circles to lock in clamping accuracy. Learn more about our high-precision clamping components on the CNC machining services page — precision ER collet manufacturing is our core offering.
- Precision structural parts: CNC handles multi-surface milling and drilling for brackets, gear blanks, and heat dissipation parts. Wire EDM shapes special tooth profiles and grooves. Surface grinders refine key datum planes to meet strict geometric tolerance standards. For hardened steel materials, we follow proven guidelines from Machining Hardened Steel Best Practices for optimal results.
II. Advantages of Wire EDM, Grinding & CNC Machining for Precision Parts
Single machining processes fall short for high-end precision parts. But combining these three processes takes our capabilities to the next level — backed by Senfa’s 100+ high-precision machining equipment and strict quality control system:
- Accuracy superposition: CNC machining centers have a repeat positioning accuracy of ±0.01mm. WEDM-LS (Wire Electrical Discharge Machining – Low Speed) hits ±0.002mm. Precision grinding tightens dimensional tolerance to within 0.001mm. The result? Micron-level finished products you can trust.
- Process complementarity: CNC excels at fast rough machining and complex curved surface milling. Wire EDM specializes in cutting hard material contours. Grinding fixes precision and surface finish issues. Together, they eliminate the limits of single processes. For professional Wire EDM insights, check out GF Machining Solutions Wire EDM Technology. Discover our tailored custom mold services that leverage this process synergy.
- Wide material adaptability: We adjust process parameters to machine aluminum alloy, stainless steel, SKD11, Cr12MoV, and more. This lets us meet material needs across industries. View our 50+ certified material options on our CNC machining service platform.
- Strong customization capability: We handle single-piece prototypes and large-batch production alike. Our multi-process setup adapts quickly to custom needs. Plus, Senfa offers 48-hour rapid technical response and lifelong consultation support.
III. Advantages of Wire EDM + Grinding + CNC Machining
Quality multi-process parts start with strict process control — aligned with Senfa’s ISO 9001, IATF 16949, and other certification standards:
- Process planning: Engineers map out the order of CNC roughing, Wire EDM cutting, and grinding based on part drawings.
- CNC rough machining: We select the right cutting tools to remove excess material, leaving precise allowances for finishing.
- Wire EDM machining: CAM software generates tool paths for Wire EDM to cut contours, grooves, and precision holes.
- Grinding machine precision grinding: Surface and cylindrical grinders refine datum planes, outer circles, and inner holes to fix errors and boost finish quality.
- Post-processing and quality inspection: After deburring and anti-rust treatment, 2D/3D measuring tools check every dimension. Our “triple inspection” system ensures zero-defect delivery.
- Packaging and delivery: Anti-collision, anti-static packaging protects parts during shipping to prevent damage.
