How to Choose the Appropriate Method for Carbon Steel Bars Customized Cutting

How to Choose the Appropriate Method for Carbon Steel Bars Customized Cutting
Laser Cutting
Applicable scenarios: High precision (±0.1 mm), medium-thin plates (≤20 mm)
Advantages: Fast speed, smooth edges, ability to cut complex shapes
Techniques: Focal adjustment, pressure control, step-by-step piercing
Case: Automotive part processing cycle shortened by 30%, with a scrap rate of <1%
Plasma Cutting
Applicable scenarios: Medium-thick plates (20-50 mm), high-efficiency requirements
Advantages: Lower cost than laser cutting, strong cutting capability
Limitations: Lower precision (kerf width 1-3 mm), requires grinding
Case: Steel structure processing time reduced from 15 minutes to 5 minutes
Flame Cutting
Applicable scenarios: Extra-thick plates (>50 mm), low-cost scenarios
Advantages: Simple equipment, low maintenance costs
Limitations: Poor precision (kerf width 3-5 mm), requires straightening
Case: Shipyard reduced per-unit cost by 40%, but straightening is required
Waterjet Cutting
Applicable scenarios: Heat-sensitive materials, no thermal deformation requirements
Advantages: High precision (kerf width 0.1-0.5 mm), no thermal impact
Limitations: Slow speed, high cost
Case: Aerospace parts have no thermal deformation, but processing time is three times that of laser cutting
Mechanical Cutting (Sawing/Shearing)
Applicable scenarios: Thin plates (<10 mm), simple low-precision requirements
Advantages: Lowest cost, simple operation
Limitations: Poor precision (kerf width 1-2 mm), requires grinding
Case: Hardware processing costs 0.5 yuan per unit, but grinding is required
