Custom CNC Clutch Plates for Construction Machinery Excavators

Xiamen Goldcattle, with 25 years of in – depth experience in the construction machinery parts field, leveraging its expertise in CNC precision machining, has pioneered the “condition – customized” model. From the high – intensity mining operations in mines to the muddy construction in wetland areas, we tailor – make exclusive clutch plates for various construction machinery excavators. Under extreme conditions, we reduce the slip rate by 85% and extend the service life by 200%, redefining the reliability standards of the power transmission system for excavators.

• Heavy – Load and High – Torque Strengthening: For the 500kN·m high – torque condition in mining, the thickness of the friction material of the clutch plate is increased by 35%, the strength of the steel plate is increased by 50%, the torque – resistance capacity is increased by 70%, and the slip risk is reduced by 90%.

• Environmental Adaptation: In the low – temperature environment of the Arctic Circle, cold – resistant friction materials (with a stable friction coefficient at – 40°C) are used. In tropical high – humidity areas, stainless – steel plates are used with moisture – proof coatings, and they can pass the salt – spray test for more than 3000 hours without rust.

Aiming at the complex stress and friction characteristics of clutch plates for construction machinery excavators under different working conditions, we carefully select four categories of high – performance materials and combine CNC precision machining to achieve condition – specific adaptation:

• Material Properties: The copper – based powder metallurgy friction material has a copper content of ≥65%, and solid lubricants such as graphite and molybdenum disulfide are added. The friction coefficient is stable between 0.35 and 0.45, and it has excellent wear – resistance. The high – strength alloy steel plate has a tensile strength of ≥1200MPa and a yield strength of ≥1000MPa, with good fatigue resistance.

• Processing Advantages:

• • The CNC pressing and sintering process ensures a uniform density of the friction material, and the bonding strength with the steel plate is increased by 80%, making it less likely to fall off under high torque.

• • The steel plate is subjected to CNC precision stamping and heat treatment, with the dimensional accuracy controlled within ±0.03mm and the flatness error ≤0.05mm, effectively improving the dynamic balance performance of the clutch plate. It is suitable for heavy – load operations such as mining and large – scale infrastructure construction, and the measured service life exceeds 10000 hours.

• Material Properties: The 304L stainless – steel plate has a carbon content of ≤0.03%, a chromium content of 18% – 20%, and a nickel content of 8% – 10%. The corrosion rate in a humid and salt – fog environment is <0.02mm/year. The special rubber – coated friction material has good waterproof and anti – slip properties, and the friction coefficient in a wet and slippery condition is ≥0.4.

• Processing Advantages:

• • The CNC laser cutting of the stainless – steel plate achieves an edge accuracy of ±0.01mm, reducing stress concentration.

• • The rubber coating is applied by the CNC spraying process, with a uniform thickness controlled between 0.8 – 1.2mm, effectively preventing the erosion of water and salt. It is suitable for wet and salty environments such as wetlands and coastal areas and can be continuously used for more than 5 years.

• Material Properties: The friction material with a ceramic fiber content of ≥30% has an oxidation – resistant temperature of up to 800°C, and the friction coefficient fluctuates <±0.05 at 400°C. The heat – resistant alloy steel plate contains alloy elements such as chromium, nickel, and molybdenum, and the yield strength at 400°C is ≥500MPa, with good high – temperature strength.

• Processing Advantages:

• • The CNC hot – pressing process ensures a tight bond between the friction material and the steel plate at high temperatures, with the bonding strength increased by 70%.

• • The heat – resistant alloy steel plate undergoes special heat treatment to eliminate internal stress, and the dimensional stability in a high – temperature environment is increased by 90%. It is suitable for high – temperature operation scenarios such as cement production and high – temperature furnaces and can operate stably at 500°C for 3000 hours.

• Material Properties: The organic friction material is based on phenolic resin and added with fiber – reinforced materials. The friction coefficient is stable between 0.3 and 0.4, with high cost – effectiveness. The high – quality carbon steel plate has a hardness of HB200 – 230 after quenching and tempering treatment, providing reliable structural support.

• Processing Advantages:

• • The CNC molding process ensures the forming accuracy of the organic friction material, and the fit clearance with the steel plate is ≤0.1mm.

• • The carbon steel plate is processed by CNC turning, with a surface roughness of Ra ≤ 1.6μm, reducing friction loss. It is suitable for ordinary conditions such as urban construction and small – scale earthwork projects, with high cost – effectiveness and meeting daily use requirements.
