Multiple Swiss-type and cam automatic lathes for flexible scheduling, stable capacity, and on-time delivery.
Spindle speed up to 15,000 RPM, designed for sub-Ø10mm ultra-small parts. Short cycle times and excellent surface finish — ideal for medical micro components and optical communication precision parts.
Ultra Small Diameter High Speed Medical / OpticalDovetail guideway structure provides exceptional rigidity with minimal vibration during cutting — delivering stable tolerances for small-to-medium diameter shafts, connectors, and complex geometry parts.
High Rigidity Stable Tolerance Complex PartsAngled turret design for effective chip evacuation — enables long continuous runs without interruption. Handles up to Ø20mm OD, balancing precision and throughput for multi-spec production.
Large Diameter Continuous Production Multi-specMechanical cam-driven with fast cycle rates and consistent timing — ideal for high-volume, mature part numbers. Low unit cost, with bar feeder automation for extended unattended operation.
High Volume Low Unit Cost Auto FeedThese capabilities represent Jian Chang's core competencies — difficult to replicate by general turning shops.
High-volume production of Ø1mm, Ø1.5mm, Ø2mm, Ø3mm micro parts — our most fundamental expertise.
Min. Ø1mm70mm, 80mm, 100mm slender shafts — high L/D ratio parts require Swiss-type guide bushing support to maintain roundness and straightness.
L/D RatioStandard ±0.01mm; precision parts ±0.0015mm — meeting close-fit assembly requirements.
±0.0015mmProven production in SUS304/316/440C, SCM440, Inconel 718, Titanium, SKH9, and other superalloys and stainless grades.
