Case Study

Automotive Shaft Production For German Tier 1 Supplier

A German Tier 1 automotive supplier manufacturing high-torque transmission shafts faced recurring quality issues, including high scrap rates, micro-vibrations, and concentricity drift exceeding 0.02mm under high-speed operation. To address these bottlenecks, our Cnc Turning Service implemented Swiss-type precision lathes equipped with multi-axis live tooling, automatic bar feeders, and in-process laser gauging systems. We customized the cutting tool path and selected optimal insert geometry specifically for hardened 20CrMo alloy steel shafts. By maintaining tight machining tolerances within ±0.005mm and concentricity under 0.008mm, workpiece runout was practically eliminated. The integrated live tooling allowed milling, turning, and keyway grooving in a single setup, cutting handling time significantly. Consequently, the client's assembly scrap rate fell from 5% to 1.2%, part rework dropped by 22%, and cycle efficiency rose.

Medical Bone Screws For US Orthopedic Firm

A leading US orthopedic medical device manufacturer required high-precision titanium (Ti-6Al-4V ELI) bone screws with ultra-fine thread profiles and a surface roughness below Ra 0.2μm. Traditional turning methods resulted in burrs on thread crests and frequent dimensional variances, risking non-compliance with stringent FDA regulatory requirements. Our Cnc Turning Service deployed high-speed Swiss-type CNC automatic lathes featuring oil-mist high-pressure coolant, thread whirling attachments, and automated optical CMM verification. By optimizing feed rates and spindle speeds under controlled thermal conditions, we achieved zero-burr thread execution and superior surface smoothness without secondary polishing. In-process laser inspection verified 100% of thread pitches and core diameters in real time. First-pass yield reached 99.8%, delivery lead time was compressed from 21 to 14 days, and the customer successfully passed comprehensive FDA audits with zero observations.

Hydraulic Valve Bodies For Italian Hydraulics Manufacturer

An Italian industrial hydraulics producer required 20,000 precision steel valve bodies per month, featuring complex internal step bores, tight O-ring grooves, and deep internal metric threads. Multi-stage handling on legacy turning centers caused setup alignment errors, high labor overhead, and a 30% cycle time bottleneck. We upgraded their production workflow through our specialized Cnc Turning Service, deploying multi-spindle CNC turning centers paired with automated magazine bar feeders and high-speed thread whirling systems. Internal geometries, counterbores, and thread features were completed in a single continuous clamping cycle, preventing concentricity errors between internal chambers. Process capability indices (Cpk) consistently exceeded 1.67 across 20,000 monthly units. This integrated strategy cut overall machining cycle time by 30%, ensured 100% thread gauge compliance, and raised on-time delivery to 98.5%, solidifying a 5-year strategic manufacturing partnership.

Cnc Turning Service is a subtractive manufacturing process where a single-point cutting tool removes material from a rotating workpiece to create cylindrical or complex geometries. Our Cnc Turning Service leverages multi-axis CNC lathes, live tooling, and automation to produce parts with tight tolerances and superior surface finishes. The process begins with raw bar stock or near-net forgings loaded into bar feeders, enabling lights-out production. We use CAD/CAM programming to optimize tool paths, reducing cycle times by up to 25% compared to conventional turning. In-process probing and post-process CMM inspection ensure adherence to ±0.005mm tolerances. Our facility in Taizhou, Jiangsu, operates 30+ CNC lathes, including Swiss-type and multi-spindle machines, serving automotive, aerospace, medical, and energy sectors.
