The core advantages of high-pressure waterjet cutting are cold cutting without heat impact, wide material adaptability, and high cut quality. Compared with traditional methods such as milling, wire cutting, and laser cutting, it differs significantly in processing principle, applicable scenarios, and cost efficiency.
High-Pressure Water Jet Cutting
Advantages:
1.Dust-free, flame-free, environmentally friendly and safe
2.Cold cutting, no heat deformation, no heat-affected zone (HAZ)
3.Unrestricted cutting materials (metal, stone, glass, composite materials, rubber, etc.)
4.Smooth cut, no secondary processing required5.Can cut complex irregular shapes, flexible cutting path
Disadvantages:
1.High precision control is required for cutting extremely thin materials
2.Cutting speed is lower than laser and plasma cutting (except for thick plates)
3.Abrasive consumption incurs consumable costs
Milling
Advantages:
Poor flexibility, difficult to cut irregular curves
High machining accuracy, capable of complex 3D forming
Suitable for multi-process machining such as milling, drilling, and chamfering
Good rigidity for machining metal parts
Disadvantages:
Tool wear is easy, resulting in high consumable costs
Low efficiency when cutting thick materials
Wire EDM:
Advantages:
1.Extremely high precision (up to ±0.005mm)
2. Suitable for complex molds and small parts processing
3. Narrow kerf, high material utilization
Disadvantages:
1. Can only process conductive materials (metals)
2. Slow cutting speed, low efficiency
3. Electrode wire wear exists, high cost
Laser Cutting
Advantages:
1. Fast cutting speed, high efficiency
2. Narrow kerf, high precision (±0.01mm) 3. High degree of automation, suitable for mass production
Disadvantages:
1. Thermal cutting has thermal deformation and heat-affected zone
2. Highly reflective materials (copper/aluminum) easily damage the laser
3. Weak ability to cut thick plates, cost increases sharply
Plasma Cutting
Advantages:
1. Fast cutting speed, high efficiency for thick metals
2. Equipment cost is lower than laser and waterjet
3. Suitable for harsh working conditions, low operating threshold.
Disadvantages:
1.Large thermal deformation, rough cut requiring secondary processing.
2.Low cutting accuracy.
3.Generates smoke, dust, and arc light pollution.
Punch Press Cutting
Advantages:
1.Extremely high batch processing efficiency and low cost.
2.Can simultaneously perform cutting, bending, and punching.
3.Strong equipment stability and simple maintenance.
Disadvantages:
1.High mold cost and long mold changeover cycle.
2.Only suitable for regular shapes and batch products.
4.Poor flexibility, unable to cut complex irregular parts.
