Combined Wire EDM & Grinding: High-Accuracy Processing for Complex Micro Parts

Custom Wire EDM and precision grinding are our core high-precision processing services, dedicated to manufacturing ultra-tight tolerance components for global industrial clients. Equipped with advanced wire electrical discharge machining equipment and professional precision grinding machines, we deliver intricate, thin-walled, hard material parts and ultra-smooth surface workpieces that conventional CNC machining struggles to produce.

As a professional custom processing manufacturer, we support prototyping, small-batch and mass production for various metal materials. Our integrated Wire EDM & grinding solutions cover full-process services from drawing review, material processing to final quality inspection. We specialize in machining complex contours, narrow slits, tiny holes and flat/round workpieces with superior dimensional accuracy and excellent surface finish, widely trusted by industries with rigorous precision standards.

Core Advantages of Wire EDM & Precision Grinding

· Extreme Machining Precision: Our process maintains ultra-high dimensional accuracy. Wire EDM achieves tolerance up to ±0.003mm, and precision grinding delivers tolerance as low as ±0.002mm, fully meeting the requirements of high-end precision manufacturing.

· Excellent Machinability for Hard Materials: Perfect for processing hardened steel, alloy steel, tungsten carbide and other high-hardness metals. No cutting force is generated during Wire EDM processing, so workpieces will not deform.

· Capability for Complex & Micro Structures: We excel at machining ultra-narrow slits, tiny holes, intricate 2D/3D profiles and thin-wall components with no tool wear or processing dead zones.

· Superior Surface Quality: Precision grinding optimizes surface roughness down to Ra 0.2μm or even lower, creating smooth, burr-free surfaces for parts requiring high wear resistance and tight fit.

· Stable Batch Consistency: Adopting automated digital control systems, all finished parts keep uniform dimensions and surface effect in mass production, effectively reducing manual errors.

· One-Stop Custom Service: We provide free drawing evaluation, process optimization, combined Wire EDM & grinding processing, surface treatment and complete quality testing. Flexible MOQ and fast lead time help you save procurement costs and shorten project cycles.

Wire EDM & Precision Grinding Technical Specifications

Standard Production Workflow

We follow a standardized and rigorous production flow for every order. Each procedure is strictly monitored to ensure outstanding precision, stable quality and reliable performance of all custom machined parts.

Detailed Process Steps Description

1. Drawing Review & Process Analysis: Our professional engineering team checks design drawings, verifies dimensions, tolerances and structural features. We formulate the optimal processing plan and offer free process optimization suggestions to avoid potential processing risks.

2. Material Cutting & Preparation: Select qualified raw materials according to customer requirements, conduct incoming material inspection, and cut materials into standard blanks for subsequent processing.

3. Wire EDM Machining: Import programmed data into Wire EDM equipment to complete contour cutting, slotting and hole machining. Non-contact processing ensures no deformation on high-hardness and thin-wall workpieces.

4. Precision Grinding: Carry out surface grinding, cylindrical grinding or form grinding as required, to calibrate dimensions and greatly improve surface finish of workpieces.

5. Deburring & Cleaning: Remove tiny burrs and stains on parts, ensure clean and smooth surfaces for follow-up treatment.

6. Surface Protection Treatment: Apply anti-rust oil or customized surface protection as requested, to enhance parts’ durability and corrosion resistance.

7. Full Quality Inspection: Use micrometers, roughness meters, coordinate measuring instruments and other precision tools to conduct 100% inspection on dimensions, tolerance and surface quality. We provide official inspection reports.

8. Packaging & Delivery: Adopt anti-collision, moisture-proof and shockproof professional packaging, then arrange safe logistics and delivery worldwide.
