Frequent equipment failures have sparked heated debate over the division of responsibilities between suppliers and customers.

In recent years, the contradiction of "frequent failures and unclear responsibilities" in equipment supply and demand cooperation has gradually become a high-frequency pain point in the industrial field. From core CNC equipment on the production line to special operation machinery in engineering scenarios, many companies have encountered the dilemma of "failures immediately after production and subsequent disputes." Disputes between the supply and demand sides over the division of responsibilities often turn small problems into major disputes that affect project progress and erode the trust between the two parties.

According to industry research data, in the past three years, 42% of projects experienced more than three malfunctions within 12 months of equipment delivery, with core component downtime accounting for over 65% of these failures. One manufacturing company reported that its core production equipment, launched in 2022, experienced five malfunctions within just eight months of delivery, including abnormal spindle noise and control system glitches. The longest single downtime was 18 hours, directly impacting monthly production capacity completion by 12% and resulting in over one million yuan in order delays. These types of malfunctions have become the trigger for supply-demand disagreements—each side insists on assigning blame, turning a simple repair request into a protracted tug-of-war.

The core of the dispute lies in the completely different standards used by the supply and demand sides to define the "cause of failure." Suppliers often attribute failures to non-standard user operations: for example, the equipment maintenance manual clearly requires "a 2-hour cooling period after no more than 12 hours of continuous operation," but users operate at full capacity for extended periods to meet production demands; or users replace non-original consumables without authorization, leading to accelerated component wear; some suppliers even refuse to assume warranty responsibility on the grounds that "users did not participate in the required operation training." Demands, on the other hand, directly point to inherent defects in the supplier's products: core components are made from low-standard general-purpose parts instead of customized wear-resistant models; insufficient redundancy in the heat dissipation design leads to a surge in failure rates under high temperatures; factory testing failed to expose hidden defects, resulting in sudden structural failures after delivery; some users also reported that suppliers only provided cursory operating instructions upon delivery, and acceptance was completed after a single impromptu training session, making it impossible to strictly define the operational correlation of subsequent failures.

More problematic is the extremely vague liability delineation clauses in most procurement contracts, which fail to provide quantifiable standards for core concepts such as "reasonable wear and tear," "design defects," and "improper operation." Once a malfunction occurs, both parties can only offer conflicting accounts. Furthermore, fault diagnosis relies on specialized equipment and technical teams; third-party assessments can cost tens of thousands of yuan and take months. These high time and financial costs make both parties more inclined towards a "passive stalemate" rather than a negotiated solution. In a 2023 infrastructure project, a large hoisting equipment purchased by the construction company experienced boom deformation within the warranty period. The supplier insisted that the construction company had exceeded the rated lifting weight, while the construction company pointed out that the boom material did not meet national standards. The stalemate lasted nearly six months. Ultimately, due to project deadlines, the construction company bore the repair costs itself, with the supplier only issuing a "technical support letter." The construction company still had to pay for the subsequent hidden costs of equipment maintenance.

This vicious cycle of "frequent failures - disputes over responsibility - losses" not only drives up the cooperation costs for both equipment suppliers and buyers, but also causes intangible damage to the trust system in the industrial sector. To break this deadlock, both parties need to shift from "post-event accountability" to "pre-event prevention": the contract stage should detail the boundaries of responsibility, clarify the identification process for failure attribution, and define the rules for cost allocation; suppliers should improve product reliability from the design stage, and buyers should establish standardized operation and maintenance mechanisms to reduce human-caused failures. Only in this way can equipment procurement shift from a "one-off transaction" to long-term, stable cooperation, allowing equipment to truly become a stable support for industrial development.
