Industrial Cutting Solutions

China’s global position in shipbuilding industry:

• China Shipbuilding Group’s new orders in 2024 account for more than 40% of the global total

• The world’s first LNG dual-fuel powered ultra-large container ship (23000TEU) manufacturer

​​Pain point focus:

• ​​Thick steel plate cutting: The thickness of the hull steel is 80-120mm, and the life of traditional tool consumables is short (ordinary grinding wheels need to be replaced after 200 cuts)
• ​​Composite material processing: Cutting of carbon fiber hull parts is prone to delamination damage (accuracy requirement ≤0.1mm)
• ​​Environmental compliance: It must comply with the IMO 2020 low sulfur emission standards, and abrasives containing phenol resin are prohibited

​​1. High-efficiency cutting system for hull steel plates​​

• ​​Product portfolio​​:

  • ​​Superhard cutting wheel​​: Made of zirconia corundum (ZA)​​, resistant to high temperatures up to ​​1600°C​**​

  • ​​Large diameter diamond saw blade​​: Φ800mm specification, single cutting depth ​​120mm​​

• ​​Technical parameters​​:

  • Cutting speed increased by 40%**: 100mm thick Q345 steel cutting is completed in 8 minutes (traditional tools take 13 minutes)

  • Tool life extended by 300%**: Single grinding wheel can complete 800+ standard cuts

  • Dust control: Equipped with nano-level dust suppression coating, PM2.5 in the working area is reduced by 65%

In the Jiangnan Shipyard 24000TEU container ship project, our cutting system shortened the block construction period by 18 days.

2. Precision machining solutions for composite materials ​​

• ​​Special tools​​:
  • ​​Low-vibration pulse grinding wheel​​: Amplitude ≤​​0.02μm​​, to prevent tearing between carbon fiber layers
  • ​​Honeycomb ceramic abrasive​​: For polishing the surface of marine radar covers (Ra≤​​0.8μm​​)
• ​​Intelligent monitoring​​:
  • Integrated​​IoT sensor​​Real-time monitoring of tool wear (automatic alarm when accuracy loss exceeds 5%)
  • Data:

Real-time parameters	Standard value	Current status
Cutting force fluctuation	<15 N	12.3 N
Temperature deviation	±5 °C	+3.2 °C

​​3. Green Shipbuilding Compliance System​​

• ​​Environmental certification​​:

  • All products have passed the ​​DNV GL environmental certification​​ (the list of banned substances complies with EU REACH regulations)

  • Biodegradable coolant: used with cutting tools, COD value ≤​​30mg/L​​

• ​​Carbon footprint management​​:

  • Carbon emissions per grinding wheel production​​1.2kg CO₂e​​ (industry average is 2.8kg)

  • Provide ​​EPD Environmental Product Declaration​​ to support the preparation of shipyard ESG reports
