1. Two Model Differentiation
ZW-KH20 Small Ring Coiling Machine
Fit for thin strip wire from 0.5×1.5mm to 1.5×3mm. Compact body with 800KG net weight, perfect for small-size flat ring, clockwork spring and miniature hardware ring production. Max wire feeding speed reaches 80m/min to boost daily output.
ZW-KH45 Heavy Duty Ring Coiling Machine
Support thick strip wire from 1×4mm up to 3×8mm. Higher total servo power of 22.2KW and larger forming space, ideal for thick industrial ring, brake scroll spring and heavy hardware ring mass processing.
2. Core Machine Advantages
- High Precision Wire Feeding: Min feeding command value down to 0.01mm, ensures consistent ring dimension for all finished parts
- Large Program Storage: Over 2000 sets of forming programs can be saved for quick model switching
- Stable Servo Driving System: 4-axis synchronous servo motor, smooth running and low failure rate
- Wide Production Range: Unlimited max feeding length to produce extra-long spiral ring components
- Humanized Operation: Independent touch control panel, simple editing and parameter adjustment without complex training
