JUGAO engineers responded quickly and urgently repaired the oil leakage of the CNC bending machine

Professional seal replacement + full machine after-sales inspection to ensure zero downtime of customer production lines

Yesterday, the technical service center of JUGAO, a well-known domestic sheet metal equipment manufacturer, received an urgent repair report from a metal products factory. A CNC bending machine at a key station had oil leakage in the hydraulic cylinder, resulting in reduced accuracy and the risk of downtime. The JUGAO after-sales team immediately activated the rapid response mechanism and completed remote fault diagnosis within 2 hours. It was confirmed that the problem was caused by the aging and failure of the main cylinder seal ring, and engineers were dispatched overnight to the customer site with the original seal kit.

After the JUGAO engineers arrived, they quickly started standardized operations:

Precise disassembly: Use special tools to disassemble the hydraulic cylinder to avoid damage to precision parts;

Replacement of seal rings: Replace with JUGAO's new generation of high-pressure fluororubber seals (temperature resistance up to 200℃/pressure resistance 35MPa), which significantly improves the reliability of the equipment under continuous stamping conditions;

In-depth inspection: Synchronously conduct full-machine inspections on the hydraulic system, guide rail accuracy, and CNC module of the bending machine to eliminate potential hidden dangers in advance;

Parameter calibration: Recalibrate the bending angle compensation value according to the ISO 9013 standard to ensure that the product tolerance is ≤±0.1mm.

The plant's equipment manager said, "JUGAO not only solved the oil leakage problem, but also proactively optimized the hydraulic system pressure curve. The equipment efficiency has increased by 5% compared to before the failure." This service also comes with the JUGAO Care annual maintenance agreement, and customers can enjoy year-round remote monitoring and priority spare parts support.

Taking this quick service as a microcosm, JUGAO is redefining the after-sales service standards for sheet metal equipment - from "passive maintenance" to "active full life cycle management." In the next three months, the JUGAO technical team will conduct a tour inspection of 100 factories across the country to help the manufacturing industry upgrade to intelligence.
