And,

Declining accuracy. Increasing defect rates. Unexpected machine stops. Recurring machine stops. These four events are warning signs that a problem is developing. Before repairing the machine, the cause must first be identified. Please refer to our Solution page for details.

(Accuracy & Defect Rates) Every trouble has multiple causes. Machines naturally lose performance over time. However, this is not a failure. Both accuracy requirements and defect-rate targets have acceptable limits. The key is to identify the cause and make adjustments before those limits are exceeded.

(Alarm Stops & Power Abnormalities) Machine components wear over time. Machines may also stop when abnormal power conditions are detected. An alarm is not a failure. It is a warning that a failure may be approaching. In many cases, the machine can be restarted by following the manufacturer's instructions. However, if the cause is not identified, the same trouble will occur again. Inspection and investigation are essential.

Machines do not fail suddenly. Declining accuracy. Increasing defect rates. Alarm stops. Recurring alarms. These are warning signs that should not be ignored. In many cases, damaged parts or devices are replaced. However, the cause that damaged them is often left unidentified. If the cause remains, the same trouble will return. Repair costs increase. Eventually, machine replacement becomes unavoidable. Whenever trouble occurs—or whenever a warning sign appears—the cause should be identified before deciding what action to take. An alarm stop is often the last opportunity to prevent a major breakdown and prolonged production downtime.

Most inquiries received by SGX involve machines that have already experienced repeated trouble. Machine type and level of damage are not important. After a detailed inspection, we propose both the repair method and the repair budget. Repair costs are generally limited to a maximum of 40% of the price of a new machine. Our target is to restore approximately 80% of original machine performance. Before delivery, we verify stable operation and confirm one week of normal production. Our warranty period is one year after delivery.
