Reference Specification
Hydraulic Cylinder inner hole machining
1. Use of precision hole boring machine. After the boring rolling, product is high
dimensional accuracy, wear resistance.
2. Use of Imported strong milling machine. First, use hole boring machine boringhole,
then milling, the intelligent control process can achieve Hole Roundnesswithin 0.01mm,
Straightness achieve 0.02/1000, Roughnessachieve Ra0.2. This process enhance the
accuracy of inner hole dimension, also it ensure the durability of the hole. All of these
make the overall performance is more remarkable
Quality Control
1.Cylinder products from purchased materials, processing, assembly, have strict
quality control.(We passed the certification of ISO/TS 16949:2009)
2.Automated cleaning equipment to ensure the cleanliness of fuel tank assembly.
3.Welding using CO2 arc welding and automatic girth welding, which ensure the
welding quality of the seal parts.
4. Full Cylinder inspection, product has 100% pass the comprehensive test then can
be delivered out from factory.
