How Much Can a Cutter Bender Rebar Process in an 8-Hour Shift?

How Much Can a Cutter Bender Rebar Machine Process in an 8-Hour Shift?

The daily output of a Cutter Bender Rebar machine depends on several factors such as the machine model, bar specifications, bending complexity, and operator skill. Below is a general reference to help estimate daily processing volume over an 8-hour shift.

Rebar Bending Cutting Combined Machine

1. Theoretical Output (Using Standard Machines as an Example)

• Simple Bends (e.g., 90° Hook):
  Average cycle time: ~20 seconds per bend
  Approx. 180 bends per hour → 1,440 bends in 8 hours

• Complex Bends (e.g., Spiral Shapes):
  Average cycle time: ~90 seconds per bend
  Approx. 40 bends per hour → 320 bends in 8 hours

2. Key Factors Affecting Output

• Bar Diameter: Larger bars (e.g., Φ20 and above) take longer to bend.

• Level of Automation: CNC bending machines typically offer 2 to 3 times higher efficiency compared to manual machines.

• Team Efficiency: Faster loading, positioning, and unloading can significantly boost overall productivity.

• Machine Condition: Worn-out or poorly maintained machines may see a 20% to 30% drop in efficiency.

3. Estimated Output in Practice

• Manual Bending Machines:
  Typically handle 800 to 1,200 bends per 8-hour shift, depending on bend complexity.

• CNC Bending Machines:
  With automatic feeding, can achieve 1,500 to 3,000 bends per 8-hour shift.

4. Recommendation for Accurate Estimation

To determine more precise output, consider the following:

• Refer to Machine Specifications: Use the “cycles/hour” rating from the user manual.

• Field Testing: Measure the actual bending time on-site using typical steel bars.

• Adjust for Real-World Conditions: Account for pauses due to adjustments, breaks, and downtime. A common adjustment is to reduce the theoretical capacity by 20%.

Example:
If a machine is rated at 200 bends/hour:
→ 200 × 8 hours × 0.8 (real-world factor) ≈ 1,280 bends per shift

Conclusion

While theoretical calculations provide a baseline, actual output should be adjusted based on on-site conditions and project-specific requirements for a more reliable estimate.
