Product Introduction

BY-3-8 CNC High-Speed Rebar Wire Straightening and Cutting Machine

Industrial-grade high-speed wire straightening and precision cutting machine designed for processing cold-rolled ribbed rebar, hot-rolled steel bar, and smooth wire. Equipped with an aerodynamic multi-rotor straightening frame and servo hydraulic rotary fly-shear, delivering ultra-high cutting speed (up to 150m/min), mirror-smooth surface finish, and length accuracy within ±1.0mm.

High-Speed Rotary Straightening
Multi-die dynamic straightening rotor utilizes hardened alloy dies to relieve internal stress without damaging wire ribs.
Fly-Shear Hydraulic Cutting
Servo-synchronized flying shear cuts wire continuously at full line speed without stopping the wire feed.
Zero Surface Marking
Dual-pair polyurethane feeding pinch rollers prevent surface scraping or rib crushing on processed rebar.
Touchscreen Batch Programming
Preset multiple cutting lengths and batch piece counts with automatic sorting and rack discharge.

Core Design & Operational Advantages

  • Hardened Alloy Straightening Dies: Tungsten/Cr12 alloy dies ensure long service life without groove wear.
  • Automatic Wire Jam Detection: Optical sensors halt feed motors instantly if wire tangling occurs at the pay-off stand.
  • Pneumatic Automatic Rack Dropper: Drops finished cut rods automatically into collection cradles upon reaching batch count.

Buyer Inquiries & Technical FAQ

Q: Does high-speed straightening damage the cold-rolled ribs on CRB550 wire?
A: No, our curved roller rotor geometry is specifically profiled to straighten ribbed rebar while preserving 100% of rib height and metallurgical properties.
Q: What is the power supply requirement?
A: Standard 380V/3-Phase/50Hz or custom 220V/415V/440V 60Hz configured according to your regional industrial grid.
