Taizhou Zhongya Auto Parts Co., Ltd.
Dual-track production: fully automated hub bearing lines and smart crankshaft lines, delivering a powerful output advantage.
Fully automated Gen-1 and Gen-2 ball-taper hub unit production line, with daily capacity of 8,000 sets. Constant-temperature clean-room assembly at 20±1°C keeps bearing clearance variation under 5 μm at a takt time of 25 seconds per set.
Four fully automated crankshaft lines carry parts from raw blank to finished product, with output of 8,000 pieces per shift. Flexible fixtures support multiple product variants with changeover under 30 minutes; in-line SPC keeps roundness within 0.003 mm.
Inclined-rail CNC lathes improve machining efficiency and precision stability, ensuring dimensional consistency across bearing inner and outer rings.
Machining centers complete multi-face drilling and milling in a single setup, ensuring hole-position consistency for high-accuracy hub flange installation.
Precisely temperature-controlled heat-treatment furnaces ensure parts meet hardness and toughness targets, extending bearing ring fatigue life.
CNC grinders fine-finish critical mating surfaces, improving dimensional accuracy and surface quality as the foundation for bearing running precision.
Superfinishing of raceway grooves reduces surface roughness, improves bearing running smoothness, and extends service life.
The 1050 centerless grinder features a hydrostatic spindle and CNC wheel dresser with robotic loading/unloading, effectively preventing surface scuffing and scratches.
Precisely machines gears and splines. Servo-driven control of rolling force and speed ensures tooth-form accuracy and surface consistency.
Mesh-belt ultrasonic cleaning removes machining residue and particles, ensuring part cleanliness meets assembly requirements and preventing contamination from entering the bearing.
Fully automated Gen-1 / Gen-2 ball-taper hub unit production line, daily capacity 8,000 sets. Integrated grease filling, riveting, and inspection at a takt of 25 s/set.
Four fully automated production lines achieve fully automated flow from raw blank to finished product, with output of 8,000 pieces per shift. Flexible fixtures support multiple product types with changeover under 30 minutes; in-line SPC keeps roundness within 0.003 mm; complete online inspection data retention ensures full traceability.
Fully automated flow from forged blank through inspection. Four lines running in parallel deliver 8,000 pieces per shift with stable year-round output.
Advanced CNC equipment and in-line inspection systems collect machining data in real time, triggering immediate alerts on any anomaly to ensure product consistency.
CNC lathes and four-axis machining centers precisely machine crankshaft journals and connecting-rod pins, holding dimensional tolerances to ±0.005 mm.
20 dedicated grinding machines enable simultaneous double-row groove machining. Roundness held within 0.003 mm; surface roughness Ra ≤ 0.4 μm.
Automated line integrates grease filling, riveting, and clearance inspection. Machine vision provides 100% cosmetic inspection at a takt of 25 s/piece — fully unmanned.
